hoolio:

wagnerrp, i've an issue with mythvideo and it's shitting me

[00:01:45]

hoolio:

we've recently started watching alot of TV series through mythvideo

[00:02:02]

hoolio:

say we have 4 or 5 or more on the go at any one time

[00:02:19]

hoolio:

it's getting really hard to remember at which point we're up to in each series

[00:02:42]

wagnerrp:

please watch the language

[00:02:49]

hoolio:

sorry matey

[00:03:12]

hoolio:

given mythvideo doesn't easily allow me to determine what we've watched and what we havent

[00:03:39]

hoolio:

how do you work it?

[00:04:45]

wagnerrp:

mythvideo has a 'watched' flag in the database, to determine what has been seen before

[00:04:51]

wagnerrp:

you should be able to filter by that

[00:05:06]

hoolio:

yeah, you can, apparently, but it's tedious.

[00:06:17]

hoolio:

and you can't get it to save that that filter as default

[00:06:42]

hoolio:

was there some talk of integrating mythvideo with mythtv recordings?

[00:06:58]

wagnerrp:

no

[00:07:02]

hoolio:

:(

[00:07:20]

wagnerrp:

there was talk, and plans, of merging and reworking the database tables used by recordings and mythvideo

[00:07:28]

wagnerrp:

but they serve two independent purposes

[00:07:33]

hoolio:

yep

[00:08:02]

hoolio:

is mythvideo getting much developer love, in general?

[00:09:06]

wagnerrp:

quite the opposite, mythvideo is no more

[00:09:40]

hoolio:

so what is the future for that functionality?

[00:10:00]

wagnerrp:

the core frontend code formerly part of mythvideo gets much developer love

[00:11:24]

hoolio:

should i be reading some roadmap or something?

[00:11:59]

hoolio:

so mythvideo code has been merged into something else

[00:12:06]

hoolio:

>

[00:12:07]

hoolio:

?

[00:12:16]

wagnerrp:

mythvideo was consumed by the frontend

[00:12:21]

wagnerrp:

it is no longer a plugin

[00:12:24]

hoolio:

okay

[00:12:32]

hoolio:

this is in .25?

[00:12:49]

wagnerrp:

yes

[00:14:06]

hoolio:

okies, so will mythvideo still be a separate menu item?

[00:14:27]

hoolio:

but with a partually rewritten ui

[00:16:06]

wagnerrp:

why would the UI be rewritten?

[00:16:39]

hoolio:

i don't know ;) i'm just trying to workout what to expect from .25

[00:17:02]

hoolio:

and if dealing with transcoded tv series will be less painful

[00:20:49]

hoolio:

and normal recordings are marked with an icon to indicate they've been watched

[00:21:21]

hoolio:

imho that sort of elegance needs to be visted upon in mythvideo

[00:21:34]

wagnerrp:

you may want to look into creating a new 'browse by' mode

[00:21:38]

hoolio:

it seems a poor cousin compared to recorded tv

[00:21:41]

hoolio:

okay

[00:21:43]

wagnerrp:

one that does something like the watch list

[00:21:53]

hoolio:

okay, i'll have a look at that

[00:22:03]

wagnerrp:

the issue is that mythvideo and recordings are for completely different purposes

[00:22:28]

hoolio:

well i think that's debatable.

[00:22:28]

wagnerrp:

their UI is dissimilar, because it doesnt make sense to organize them in the same manner

[00:22:59]

hoolio:

when it comes to TV series, it makes complete sense for the UIs to be similar

[00:23:17]

hoolio:

but for normal video content, i can understand why a difference is okay

[00:24:00]

wagnerrp:

well if you want a relatively easy way of altering how content is displayed in mythvideo

[00:24:07]

wagnerrp:

look into the browse by mechanisms

[00:24:29]

hoolio:

okay, i have done so trivially, but i'll look into it some more.

[00:27:01]

hoolio:

from an end users perspective, can you see why having to handle transcoded tv series differently to recorded tv series makes not a lot of sense?

[00:28:12]

wagnerrp:

no, because transcoded tv series are still in recorded programs

[00:28:20]

wagnerrp:

mythvideo is intended as a long term archive

[00:29:28]

hoolio:

s/transcoded/not-recorded

[00:29:47]

wagnerrp:

so... DVDs and Bluray

[00:30:19]

hoolio:

did you ever see the downloadable TV series called "the scene"?

[00:30:57]

wagnerrp:

http://www.welcometothescene.com/index.php ?

[00:31:10]

hoolio:

yep

[00:31:41]

wagnerrp:

so... not transcoded

[00:31:49]

wagnerrp:

its simply in the format it is distributed in

[00:31:52]

hoolio:

yeah

[00:31:58]

hoolio:

s/transcoded/not-recorded

[00:32:11]

hoolio:

my point being, it's a TV series

[00:32:32]

hoolio:

and in myth we have a beautifully elegant mechanism to watch tv series; recorded programs

[00:32:54]

hoolio:

yet because this content didnt originate from within myth, i have to wrestle with mythvideo

k-man:

wagnerrp, the recent stuff to support BBC iPlayer – is that to enable recording of bbc content from internet (as opposed to FTA)?

[00:35:35]

k-man:

oh, it was ticket not a commit

[00:35:39]

wagnerrp:

k-man: i believe it is something to do with interactive content on broadcast

[00:35:42]

k-man:

10019

[00:35:48]

k-man:

ah ok

[00:35:53]

wagnerrp:

hoolio: i would say in response, stop wasting CPU transcoding and just get a bigger hard drive

[00:36:18]

hoolio:

ok, say they are watching VOBs then

[00:36:22]

wagnerrp:

k-man: yeah, mheg is interactive broadcast tv

[00:36:32]

hoolio:

my point is it's inelegant to watch TV series from mythvideo

[00:36:39]

hoolio:

but myth forces us to.

[00:37:19]

k-man:

wagnerrp, ah yeah, I remember now

[00:37:23]

wagnerrp:

the 'watched' flag is likely exposes to the theme

[00:37:43]

wagnerrp:

chances are you could modify the theme and make it display something to indicate watched-ness

[00:37:49]

wagnerrp:

either give it an icon

[00:37:58]

wagnerrp:

or darken the shows that have been watched

[00:38:03]

wagnerrp:

or, whatever you want

[00:38:25]

hoolio:

yes, okay.

[00:38:43]

hoolio:

it just seems like some odd parallel evolution because recorded TV already does all i want

[00:41:04]

hoolio:

anyhow, like you've said i'll have a go hacking the theme, thanks for hearing me out.

[00:41:46]

westlock:

[17:47] <wagnerrp> so you add all eight inputs through their respective types

[00:41:57]

westlock:

[17:49] <wagnerrp> and then you add the mutually exclusive inputs each to their own input group

[00:42:19]

wagnerrp:

so adapter0 and video0 will be in one input group

[00:42:27]

wagnerrp:

adapter1 and video1 will be in another input group

[00:42:28]

wagnerrp:

etc...

[00:43:57]

westlock:

It seems to make input groups for me based on the dvb adapters0frontend0 adapter1frontend0 adapter2frontend0 adapter3frontend0

[00:45:02]

westlock:

The Input group #1 has usually adapter0–3frontend0 in it and for input group #2 it has generic? Do I do anything with the generic?

[00:46:05]

wagnerrp:

change 'generic' to something else, whatever string you want

[00:46:17]

wagnerrp:

then on video0, set one of those groups to that same string

[00:46:19]

westlock:

Okay I've done that and it is called analog

[00:46:33]

wagnerrp:

no, because you have four independent analog inputs

[00:46:42]

wagnerrp:

and they can all operate at the same time

[00:46:50]

wagnerrp:

only one tuner in an input group can be used at a time

[00:46:59]

wagnerrp:

they define mutual exclusivity

[00:47:15]

westlock:

So your saying I need analog0 analog1 analog2 analog3 as options for input group 2

[00:47:24]

wagnerrp:

sure, if you want to call them that

[00:49:55]

westlock:

okay I will attempt to implement. Is there a resource online that has pictures and information. Actual screenshots would be good buth then if it could be done in ascii art that would even help. Oh and wagnerrp << you are a big help too.

[00:50:19]

wagnerrp:

not that i am aware of

[00:50:28]

wagnerrp:

you can search the wiki, but ive never personally used input groups

[00:52:11]

westlock:

It is not a big step to change video0–3 from input group 2 from the current analog setting to 4 independent groups i.e.: analog0 analog1 analog2 analog 3 each paired with their accompanying adapter0–3frontend0 input group #1 setting.

[00:52:54]

westlock:

And I've defined all video0–3 as ivtv cards.

[00:53:25]

westlock:

I'ma make that happen.

[00:56:55]

westlock1:

whats up with the regx

[00:57:38]

westlock1:

nvm

[00:59:30]

westlock:

./mythfilldatabase

[00:59:54]

westlock:

All changes completed sucessfully. Testing....

[01:00:31]

westlock:

Made way more sense doing it that way as well. Hope to see some welcome changes in the log files.

[01:02:11]

westlock:

I have the video0–3 cards tuned to their own source and the adapter0–3frontend0 cards tuned to use a different television source. Is that correct?

[01:02:24]

westlock:

Thought I better ask...

[01:02:51]

westlock:

Good question relevant?

[01:02:57]

westlock:

I don't know what are you going to type.

[01:03:29]

wagnerrp:

you should have two sources, one for analog and one for digital

[01:04:00]

westlock:

that we do. k mythfill is done so will test now.

[01:05:06]

wagnerrp:

you keep running stuff in the local path, ./mythfilldatabase ./mythfrontend

[01:05:06]

wagnerrp:

why?

[01:08:29]

westlock1:

http://pastebin.com/wWdT62xM front

[01:10:03]

wagnerrp:

well thats completely illegible

[01:10:57]

westlock:

http://pastebin.com/Ybjwhw5H backend log

[01:18:06]

westlock:

You ask why I'm running that way and I'm not sure how to answer. I have always gone to /usr/bin to run the commands. Am I too somehow be doing this through the web interface or the program itself? I mean I can click on and run myth-frontend from the start menu but then how do I get to see what is going on with the logs pertaining to the client. Does it make a difference where I run mythfilldatabase from? When I run it the way I do I see output

[01:18:07]

westlock:

to the stdout as it is running. I can provide that output as well.

[01:19:05]

westlock:

Oh and I don't actually need eight different video sources defined do I/

[01:19:13]

westlock:

?

westlock1 (westlock1!~mythtv@24.65.240.253) has quit (Ping timeout: 246 seconds)

[01:21:11]

westlock:

I tested and same thing. Immediate video for 1 second followed by blue screen. Channel guide is spot on. Have all my regular channels. Of course no audio. I know on older bt848 cards if the audio wasn't working it would stall the recording. Would the same hold true in this instance? Someone said I could simply disable pulseaudio before is that correct?

[01:24:13]

wagnerrp:

westlock: /usr/bin should be in your $PATH variable

[01:24:37]

wagnerrp:

for any command in a directory listed in your $PATH, you just need to run the command

[01:24:43]

wagnerrp:

you do not need to specify what file to run

[01:25:10]

wagnerrp:

IVTV cards record the audio and store it in the mpeg file internally

[01:25:21]

wagnerrp:

mythtv never sees the audio to screw it up during recording

[01:25:40]

wagnerrp:

as mentioned, you only need two sources

[01:25:44]

wagnerrp:

one for digital, one for analog

[01:25:52]

wagnerrp:

you can map multiple cards to a single source

[01:36:42]

westlock:

Okay I will try that now.

[01:37:48]

westlock:

the other source will not be mapped to anything and SD will complain as also it will be noted in the logs. I am not removing a good video source as channel scanning is brutal.

Besides you can't delete only one video source. Appears to be all or nothing.

Unless I could go and delete a record in a table somewhere and be done with it.

sure you can

[01:39:07]

highlight it, press d

[01:39:37]

Well that is a 8 hour channel scan roundabout gotcha.

[01:58:14]

westlock:

didn't delete the analog video source defined earlier. Implications?

[01:59:06]

wagnerrp:

all eight from one source?

[02:01:03]

westlock:

yes before I had what I thought was a TV source assigned to all the adapter0–3frontend0 devices and the analog TV source assigned to all the video0–3 devices

[02:02:11]

westlock:

when I push c or y I can sometimes change tuners but usually not a good idea.

[02:02:55]

wagnerrp:

no, you need two sources

[02:03:02]

wagnerrp:

one for your analog tuners, one for your digital tuners

[02:03:13]

wagnerrp:

the video source contains the list of channels

[02:03:27]

wagnerrp:

all tuners mapped to that source must be able to access all channels contained within that source

okay so I'll change it back. But I had no video at that point so would the problem then lie in the playback profiles?

[02:04:09]

wagnerrp:

first thing to check is the backend logs, to make sure it is actually recording something

[02:04:32]

westlock:

it records. I'll put some data in the log.

[02:09:49]

sphery:

it cleans out everything you've defined before that didn't work, so you're starting fresh--as if from a new database (but without affecting anything other than capture cards, video sources, input connections, and channels)

[02:14:40]

westlock1:

does it wreck my channels ?

[02:17:33]

westlock1:

in the video scource setup -> Channel frequency table: <options list> us-cable > try-all > us-bcast > us-cable > us-cable-irc etc... Does this apply differently to different video sources?

[02:28:55]

wagnerrp:

it has been moved

[02:29:19]

wagnerrp:

its more explicitly located in 0.25

[02:29:36]

sphery:

but yet it does apply, generally, to all users of sound--tv, video, music, ...

[02:29:49]

wagnerrp:

well... except it doesnt

[02:29:57]

wagnerrp:

music doesnt use that audio device does it?

[02:30:04]

sphery:

though, I will admit our setup menus were unnavigable, we're working slowly to fix that

[02:30:16]

snsumner:

So I changed the default sound device to device 3 which is my HDMI audio

[02:30:26]

snsumner:

I'm assuming that I need to restart frontend?

[02:30:38]

sphery:

main problem isn't where things are/were, but the fact that there are 2,323,028 different setup options

[02:30:48]

wagnerrp:

snsumner: you shouldnt, no

[02:31:08]

snsumner:

Well, I change the sound settings but no sound still

[02:31:08]

** sphery should really finish that 95% complete patch that removes 2 **

[02:31:30]

snsumner:

I'm watching ESPNHD without sound

[02:31:33]

sphery:

snsumner: what specifically does it call it

[02:31:43]

sphery:

if it calls it "device 3", it's definitely not right

[02:31:43]

snsumner:

the device?

[02:31:51]

sphery:

if it's something else, it might not be right

[02:32:16]

snsumner:

I clicked "Scan for audio devices"

[02:32:17]

sphery:

because when you scan you get a list of all the things it finds plus whatever garbage you had selected, before, even if the previously-selected garbage was invalid

[02:32:28]

snsumner:

Then under Audio output device

[02:32:31]

snsumner:

I selected

[02:32:33]

sphery:

so I recommend scan, choose something at random, then scan, then choose what you think it is

[02:32:41]

sphery:

yeah, what's it call the device

[02:32:48]

snsumner:

ALSA:dmix:CARD=NVidia,DEV=3

[02:32:54]

snsumner:

when I ran aplay -l

[02:33:08]

snsumner:

My hdmi was card 0 device 3

[02:33:22]

snsumner:

I have Dolby Digital checked

[02:33:34]

snsumner:

my Samsung is a stereo TV but it can decode DD

[02:33:38]

snsumner:

I have DTS unchecked

[02:33:46]

sphery:

I'm not sure what to do next

[02:33:48]

snsumner:

westlock1:

The shared library was not found.

[02:35:38]

snsumner:

sphery you might be on to something

[02:35:39]

wagnerrp:

mythtv does not use gstreamer for anything

[02:35:40]

westlock1:

I have that annoying popup on the client continuously.

[02:35:54]

westlock1:

Would that affect my playback?

[02:36:05]

snsumner:

after second scan there is a new device called: ALSA:hdmi:CARD=NVidia,DEV=0

[02:36:09]

snsumner:

that sounds better, right?

[02:36:15]

westlock1:

happens as soon as I start the desktop.

[02:38:07]

snsumner:

Well I changed the device still no sound

[02:38:30]

[02:41:19]

snsumner:

wagnerrp, well I changed the device to ALSA:hdmi:CARD=NVidia,DEV=0 and I'm still not getting sound.

[02:41:43]

sphery:

westlock: yeah, as wagnerrp said, something else is using gstreamer--not MythTV

[02:42:22]

attempting to build from git-master

[02:42:56]

sphery:

westlock: closest MythTV gets is when you use MythBrowser or MythNetvision to view a page with Flash, Qt-Webkit uses Phonon, which uses gstreamer (but MythTV never ever talks to either gstreamer or Phonon--that's all internal stuff in Qt)

[03:00:58]

snsumner:

If I plug headphones into the front and change it to default the sound works.

[03:01:03]

snsumner:

so I know the sound drivers are working

[03:01:09]

snsumner:

the issue is getting the sound through HDMI

[03:01:20]

wagnerrp:

thats often a problem

[03:02:20]

snsumner:

There is so many settings so its confusing.

[03:12:56]

rhpot1991:

detect your audio devices and try them all

[03:13:45]

rhpot1991:

and make sure that all of the s/pdif outputs in alsamixer are unmuted

[03:13:48]

rhpot1991:

snsumner: ^

[03:16:09]

snsumner:

why do you have to have s/pdif output in alsamixer unmuted?

[03:16:14]

snsumner:

if you are using HDMI?

[03:16:54]

wagnerrp:

sphery: --do-channel-updates, --remove-new-channels, --refresh-today/second/all/day, --dont-refresh-tab options all only function with schedules direct, correct?

[03:21:50]

snsumner:

rhpot1991 I'm having troube finding s/pdif output on mixer

[03:22:02]

rhpot1991:

snsumner: cause one of them will be your hdmi output

[03:22:18]

rhpot1991:

snsumner: hit menu, make sure you are on the nvidia card and not an intel one or something

[03:22:51]

snsumner:

what do you mean by hit menu?

[03:23:07]

rhpot1991:

F6 actually

[03:23:55]

snsumner:

rhpot1991 you are the man

[03:24:22]

snsumner:

The issue was that s/pdif was muted

[03:24:26]

snsumner:

by default that is lame

[03:25:35]

snsumner:

Within mixer I went under playback

[03:25:50]

snsumner:

and found surround, center, LFE, side muted

[03:26:02]

snsumner:

after unmuting it fixed it.

[03:26:45]

Does anyone know how you switch tuners within Myth? I hit C and it just shows my current tuner it doesn't switch to the other one.

wagnerrp: --remove-new-channels is definitely DD only

[04:10:27]

westlock:

snumner you might try naming them each (optional) Then you will see it in the middle of the OSD at the top. From what I can tell anyhow. If that pertains to changing I'm not sure.

[04:11:10]

snsumner:

I have both of them labeled differently.

[04:11:19]

snsumner:

what I don't know how to do is switch between them in from the frontend

[04:11:54]

westlock:

y or c but I'm one to talk.

[04:12:24]

sphery:

snsumner: C = NEXTINPUT you want NEXTCARD... That means you need to map a key to it

[04:12:35]

sphery:

snsumner: or just use MENU (M) then find the option in the menu

[04:13:07]

snsumner:

what is the hotkey for nextcard?

[04:13:38]

That means you need to map a key to it

Hi, how can i confirm that mythfrontend is running in realtime mode? I changed my limits.conf, but playback is not better..

[16:46:36]

wagnerrp:

why would you want to run mythfrontend in realtime mode?

[16:48:35]

oopepe:

Ive read that it can boost the performance a little. I cannot watch dvb-c hdtv (720p) smoothly.

[16:49:21]

wagnerrp:

it will boost the performance very marginally, at the expense of other operations taking place on your system, operations that may be critical to the stability of the system

[16:50:17]

wagnerrp:

and if this is a combined frontend/backend, it will be at the expense of recording, causing faults all throughout the backend as it gets starved of cycles and IO

[16:50:59]

[16:51:13]

wagnerrp:

realtime operation is something that should be used because a task has to be performed right now

[16:51:32]

wagnerrp:

in your case, using it because you need more power, it is a _very_bad_ idea

[16:51:49]

oopepe:

Ok

[16:51:56]

wagnerrp:

what is your system?

[16:53:07]

oopepe:

Ive seen that mythfrontend uses ~105% cpu. I have a a dualcore atom with hyperthreading so i have 4 cpus. My system is at 60% idle while mythtv is playing tv. Doesnt mythtv use threads or something?

[16:53:22]

wagnerrp:

well see, theres your problem

[16:53:35]

wagnerrp:

you bought an Atom, and apparently not one with nvidia graphics you could offload to

[16:53:40]

dekarl:

oopepe: with nvidia graphics on ion? you have playback via vpdau enabled?

[16:53:52]

oopepe:

sadly without ion

[16:54:03]

oopepe:

so its not possible??

[16:54:09]

wagnerrp:

h264 playback can use threads, if the video is encoded in such a manner to support multithreaded decoding

[16:54:12]

oopepe:

the cpu is 60% idle..

[16:54:17]

wagnerrp:

mpeg2 playback cannot use threads

[16:54:24]

oopepe:

i see

[16:54:33]

oopepe:

i get mpeg2 streams :(

[16:54:47]

dekarl:

wagnerrp: likely h.264 720p50, need too look for the other parameters..

[16:54:48]

wagnerrp:

note that deinterlacing /can/ be run in a separate thread, so your CPU only need to be sufficiently powerful enough for decoding alone

[16:55:00]

dekarl:

oopepe: which channel is that?

[16:55:17]

wagnerrp:

ah, right... 720p so no deinterlacing

[16:55:45]

oopepe:

zdf hd for example.

[16:56:11]

dekarl:

ok, then i guessed right :)

[17:02:27]

[17:02:53]

dekarl:

actually doing as suggested in the error message made it a bit better for me (I get the same error)

[17:03:04]

dekarl:

> irq 16: nobody cared (try booting with the "irqpoll" option)

[17:03:54]

Seeker`:

dekarl: how do I do that? Just add it to the kernel in grub

[17:03:56]

dekarl:

I suspect conflicting commands to the card, but don't know how to debug that... (e.g. EIT Scanner and Recorder fighting over the tuner)

[17:04:01]

dekarl:

exactly

[17:04:45]

dekarl:

if it's mythbuntu try there /etc/default/grub:GRUB_CMDLINE_LINUX="irqpoll"

[17:05:17]

dekarl:

but you should be aware that it does not solve the problem, it's just a workaround

[17:07:41]

Seeker`:

dekarl: as long as the end result is that it doesn't invoke girlfriend rage i dont care atm :P

[17:09:04]

dekarl:

Seeker`: then it's not for you! It lowered the fault rate for me, but not to zero...

if i delete a show i've recorded from the "Manage recordings". is it going to delete all traces of it? (or will it know not to re-record that same episode again if it comes on)

will give it a go, thanks

i was faulting elsewhere because i had no X server

because of the manner that value is processed

[18:23:14]

wagnerrp:

it has to be run after the application is set up

which means the X server already needs to be polled

there's no log – even with -v all

youve only mentioned it about half a dozen times havent you?

sure you can

But that's not Asrocks fault ;)

[18:32:59]

I just thought it was funny to see a thread, "[mythtv-users] Possible 'holy grail' of frontends?" after days of getting yelled at for telling people that there exists an ASRock Vision 3D with nvidia GPU and a real (non-Atom) CPU so buying Atom is a bad idea--since it offended their sensibilities that I might be suggesting that they might just get what they pay for with an dirt-cheap Atom box

sphery: how do I get a backtrace if it doesn't crash?

[18:39:44]

wagnerrp:

actually, thats not true

[18:40:03]

wagnerrp:

command line arguments are now stored in a reference counting class

[18:40:07]

wagnerrp:

and the reference counter has a mutex

[18:40:19]

wagnerrp:

but that mutex is only used to control editing of the counter

[18:40:28]

it should not be possible to block on that

yeah, that makes no sense

[18:45:12]

wagnerrp:

its faulting within libs/libmythbase/mythcommandlineparser.cpp: CommandLineArg::ReconcileLinks

[18:45:21]

wagnerrp:

but that shouldnt happen

[18:45:35]

wagnerrp:

its not actually dealing with any mutexes

[18:45:43]

wagnerrp:

the parent class, ReferenceCounter, is

[18:45:53]

wagnerrp:

but that is used in several other places in the code with no problems

[18:49:09]

somedude:

I can try to put some debug statements in and figure out where it dies in that method

[18:50:59]

sphery:

or get a backtrace :)

[18:51:12]

i need to add some debugging anyway

[18:51:13]

[19:12:52]

wagnerrp:

its faulting here... https://github.com/MythTV/mythtv/blob/master/ . . . nter.cpp#L24

[19:14:28]

sphery:

wagnerrp: not sure, but it looks like it's double-unlocking the mutex

[19:14:35]

sphery:

Beirdo would be a better person to ask...

[19:15:16]

sphery:

I think there's something about a recursive lock if you need to be able to do that--but I'm guessing in this case it's just an extra call caused by an untested path

[19:15:31]

wagnerrp:

double locking where?

[19:15:46]

wagnerrp:

the only place the mutex is used is in those UpRef and DownRef methods

[19:15:50]

Beirdo:

double locking whore?

[19:16:33]

sphery:

ah, wait, there are 2 backtraces in there

[19:16:38]

sphery:

so not double-unlocking

I have the same output for me network frontend

[19:24:59]

FabriceMG:

and on mythfrontend.log -> Starting mythfrontend.real..

[19:25:16]

sphery:

you said it works on one and not on the other? is the one it works on local to the master backend (like FabriceMG's?)

[19:25:38]

Hoochster:

so I got my HDHomerun Prime over the weekend, just now getting around to setting it up, anything special I should know? I am going to go without cable card for now to see what I get

[19:26:03]

somedude:

sphery: it works on the remote frontend but not on the machine that also has the backend

[19:26:03]

iamlindoro:

If you are going without the cable card, it's just a regular HDHomeRun

[19:26:17]

Hoochster:

ahh so will only get the locals then

[19:26:21]

iamlindoro:

You don't need to know anything special until you get the cablecard and get it activated

[19:26:29]

FabriceMG:

the reverse for me

[19:26:39]

iamlindoro:

At which point you will need to redo your configuration of the devices and lineups from scratch

[19:26:44]

Hoochster:

ok guess I will be calling and fight the cable company to get me a card, thank you for the reply iamlindoro

[19:26:48]

iamlindoro:

np

[19:26:57]

Hoochster:

not worried bout redoing, I was running off pvr-150's and am happy to get rid of em heh

[19:27:05]

sphery:

FabriceMG: so the frontend that's local to the backend doesn't work, but the one on a remote system works?

[19:27:15]

iamlindoro:

Once you have the card, and you are 100% sure it is paried and activated, you can follow http://www.mythtv.org/wiki/Configuring_MythTV . . . omeRun_Prime

[19:27:50]

Hoochster:

I should be able to test activation etc just using the hdhomerun config app I assume?

[19:28:12]

Hoochster:

thanks for the link

[19:28:14]

iamlindoro:

You will verify correct pairing and activation status from the tuner's web page

sphery, work on master backend, don't work on my laptop

ohh heh shows how much I know being as I haven't even cracked open anything yet heh didn't know it had a webpage cool

sphery:

that's good news, though--since I can't effectively test a remote frontend on my dev system

[19:29:49]

sphery:

and it means that the remote vs local is likely not related

[19:29:53]

iamlindoro:

Hoochster: You should read the SiliconDust Forums, as you are likely to run into sissue getting the cablecard paired, activated, and provisioned-- and knowing what others have run into is extremely helpful

in theory profile and release are identical with the exception that release actually strips the debug symbols during make install

[19:32:43]

FabriceMG:

I don't compile, I use the ppa mythbuntu

[19:32:51]

somedude:

maybe it's a timing issue that "profile" takes slightly longer to start and hits the issue?

[19:32:57]

sphery:

but I always build profile on my dev systems, so I'll find out

[19:33:18]

yeah, very much sounds like a timing issue

sphery: if I have three multiple video sources, and I need to rescan for one of them, do I need to delete the whole video source and recreate it?

[19:33:35]

skd5aner:

sphery: I know there's a method of best approach

[19:34:05]

sphery:

skd5aner: no need to, but if you don't, you may have to clean up leftover "garbage" manually after the rescan

[19:35:14]

sphery:

I always do because a) I have only one video source, and b) starting from an empty video source means that the only channels I'll have are actually valid channels.

[19:36:00]

sphery:

with multiple video sources, though, it becomes more challenging to delete first since it means you should also do a "Delete all capture cards" after you delete and re-create that one video source

[19:36:16]

sphery:

(so that your inputs are connected in the right order)

[19:36:43]

sphery:

that said, "Delete all capture cards" should take 2 mins to redo.... :)

skd5aner:

sphery: sorry, had a call come in... yea, it's such a pain in the arse

[20:02:32]

skd5aner:

sphery: I'm wondering if I can just get away with rescanning without deleting anything?

[20:03:30]

skd5aner:

sphery: if I go into mythtv-setup | channel editor – and just do "channel scan" – it should overwrite everything correctly I would think? what risks would that lead to?

[20:03:46]

sphery:

old channels that no longer exist may remain

[20:04:13]

sphery:

new channels may be created instead of overwriting details of existing channels where insufficient information exists to know they're supposed to be the same

[20:04:16]

sphery:

things like that

[20:04:32]

skd5aner:

well, I could "delete all" channels too for a source, then rescan, right?

[20:04:33]

sphery:

basically, you'll have to go through the list of channels in the channel editor and figure out which ones shouldn't be there

[20:04:42]

sphery:

and possibly update xmltvid for ones that didn't merge properly

[20:04:47]

skd5aner:

I've got to do that anyway...

[20:04:53]

skd5aner:

icons, xmltvid, etc

[20:05:09]

skd5aner:

luckily, I've saved some sql querries to do joins against a backup table to pull some of that stuff over

[20:05:19]

sphery:

could do it that way

[20:05:53]

skd5aner:

yea, I'll just delete all channels for the source, rescan, and fill in the blanks

[20:05:57]

sphery:

is there a delete all channels button?

[20:06:00]

skd5aner:

yes

[20:06:05]

sphery:

then, yeah, should be easy enough

[20:07:39]

skd5aner:

lol – it didn't do anything though

[20:07:49]

skd5aner:

don't know if it's a bug because it's not hooked up or what?

[20:10:22]

sphery:

:( My mythfrontend works.

[20:10:43]

sphery:

skd5aner: not hooked up?

[20:10:50]

sphery:

you mean video source isn't connected to inputs?

[20:10:56]

skd5aner:

heh... no

[20:11:03]

skd5aner:

in mythtv setup | channel editor

[20:11:08]

sphery:

in which case, you might as well just delete the video source

[20:11:24]

skd5aner:

you can select a particular video source, and look at the channels associated with that video source...

[20:11:45]

skd5aner:

there is a "Delete All" button under list options...

[20:11:45]

sphery:

since you'll have to connect inputs eventually--whether the video source is new or not makes no difference

[20:11:50]

sphery:

just delete that one video source

[20:12:24]

sphery:

and it will delete the associated channels

[20:12:25]

skd5aner:

when I hit delete all, it says "delete all channels on %sourcename%?" ok or cancel

[20:12:30]

skd5aner:

I hit OK, and nothing happens

[20:12:44]

skd5aner:

seems the code isn't hooked up to actually do anything

[20:13:42]

it's hooked up in master

[20:21:47]

skd5aner:

but the button I described inthe channel editor is working for you? (in master)?

[20:22:11]

the button in channel editor, which is improperly labeled "Delete Source" in my theme pops up a dialog

sphery:

you can have mythfrontend take you to the guide before entering live tv

[20:34:24]

you can't tell mythfrontend to start up and go directly to live tv mode

[20:34:51]

somedude:

sphery: it looks like m_reflock is null at the time it gets passed to the QMutexLocker – could it be an initialization issue – something in the constructor?

sphery:

we need a thread log

[20:43:34]

wagnerrp:

there is only the single thread at then

[20:43:35]

somedude:

there's a "delete this" in downref

[20:43:54]

wagnerrp:

yes, when the counter hits zero, it deletes itself

[20:44:18]

wagnerrp:

its so you can have a single object, pointed to from multiple locations

[20:44:31]

wagnerrp:

and easily track how many users you have so you can delete it when it is no longer needed

[20:44:33]

sphery:

can't seem to fail it when I use a verbose log

[20:44:34]

somedude:

since it defaults to 1 and the first thing that gets called is "downRef" does that mean the commandlinarg will delete it self?

[20:44:36]

simple memory management

[20:44:53]

what if the delete releases the memory to the m_refLock before the qlocker can unlock it?

somedude:

would that cause the issue?

[20:45:50]

wagnerrp:

somedude: that may do it

[20:47:02]

sphery:

yeah, since you're using a QMutexLocker local variable, it's doing an unlock() on the QMutex when the QMutexLocker goes out of scope

[20:47:22]

sphery:

might need to switch it to use the QMutex directly so you control when/if the unlock() occurs

[20:49:34]

sphery:

wagnerrp: alternatively, you could just put { } around the first 3 lines of ReferenceCounter::DownRef()

somedude:

Do you really want to delete a CommandLineArg when it is blocking another arg? Maybe it's doing a DownRef when it doesn't need to?

[20:50:38]

I think you'll have to use the QMutex direclty in DownRef()

[20:50:57]

wagnerrp:

somedude: i havent actually hooked up the memory management to work properly

[20:51:34]

wagnerrp:

the only place downref gets called currently is for the temporary CommandLineArgs generated before the dependencies are reconciled

[20:51:43]

wagnerrp:

rather than having to supply the correct commandlinearg

[20:51:50]

you just supply the name of one

no, couple month old phenom ii

[21:03:27]

wagnerrp:

but were not talking about a significant difference in performance

[21:05:00]

maybe it's more related to RAM speed or which linux memory manager or (bad) luck at compile time?

linux?

[21:06:05]

aren't there different linux memory management strategies that you (or the distro) can configure?

Hey, could any of you guys tell me if the mythtv OSD is rendered via QT?

[21:54:34]

… or is it using something like Qt when in menus, but OpenGL when rendering the OSD?

[21:54:45]

skd5aner:

depends on the rendor selected :)

[21:54:48]

skd5aner:

(I think)

[21:55:38]

devinheitmueller:

fair enough. I haven't dug into the source yet – figured it might just be quicker to ask.

[21:55:43]

devinheitmueller:

thanks.

[21:55:58]

sphery:

yeah, that's basically it...

[21:56:04]

sphery:

though it's using mythui

[21:56:12]

sphery:

which may be using a Qt painter in menus

[21:56:20]

skd5aner:

could be opengl, could be Xv

[21:56:22]

skd5aner:

coudl be Qt

[21:56:23]

sphery:

but it's not Qt widgets per se

[21:57:26]

devinheitmueller:

The hand-made GUI toolkit in tvtime is driving me nuts. Just wondering what everybody else is using (e.g. 10 foot display so the typical widgets is not an option)

[21:57:57]

devinheitmueller:

Anyway, off-topic. Carry on. :-)

[21:59:26]

sphery:

yeah, that's why we have mythui--because the Qt widgets are all 2-ft UI widgets, so don't work right

[21:59:55]

sphery:

reference all the complaints about how mythfrontend setup and mythtv-setup UIs don't work at X resolution or are too small to read on TV or ...

[22:00:15]

devinheitmueller:

Yup.

[22:00:24]

sphery:

so we have mythui, which is basically our hand-made GUI toolkit

[22:00:57]

sphery:

but sounds like Chutt's/stuartm's hands are more skilled than those of the tvtime toolkit creators :)

[22:01:06]

devinheitmueller:

I am trying to get away from hand-made toolkits, which is why it is useful for you to point out that myth did this via their own toolkit built on top of Qt, rather than using functionality that is already in the core Qt toolkit.

[22:01:41]

devinheitmueller:

Well, the tvtime toolkit does far less, and I'm sure the developer invested *much* less time in developing it since it didn't need to support everything under the sun.

I would be tempted to reuse mythui, but I would imagine little effort had been made to separate it out from the rest of Myth, meaning the dependency tree would be enormous.

Is there any benefit to choosing "Test Decryptability" when scanning QAM channels?

libmythui is relatively low in the dep order, but it's not the bottom

[22:04:33]

[22:04:36]

minimally libmythbase is below it

iamlindoro: that's what I figured.

skd5aner: no, all it does is try to activate the CI bits

[22:05:06]

thought so... thanks

[22:05:10]

iamlindoro:

skd5aner: Yes, there is a benefit

[22:05:34]

skd5aner:

for non-cam type QAM/ATSC tuner cards?

[22:05:40]

iamlindoro:

The stream says its encrypted, test decryptability checks to see if it's actually true

[22:06:09]

skd5aner:

ah – so the headend could flag it as one thing, but it not actually be true?

[22:06:10]

iamlindoro:

It needn't always be

[22:06:23]

iamlindoro:

yes

[22:06:50]

iamlindoro:

Though evidently on many systems the time penalty for checking decryptability makes scans take an enormous amount of time, which is why it's off by default

[22:07:12]

sphery:

wagnerrp: are you OK with my pushing a slightly-modified version of http://code.mythtv.org/trac/ticket/10015 (that just checks the current value before setuid, and sets it back to whatever it was before)?

iamlindoro:

Though I believe that would be more of a problem in actual encrypted/CAM-using systems

[22:07:22]

skd5aner:

well, I'll let you know how long it might take me

[22:07:35]

sphery:

seems upstart can use a different user if you have it call a script

but when that script does an su or whatever to mythtv user, consolekit sees it as a user logging in and sets console and other devices to be owned by the mythtv user

i see VDPAU as a "thats nice to have" feature

considering with a 2.8GHz dual core athlon, you should have no need for hardware acceleration

[23:41:44]

sphery:

wagnerrp: so, for an AMD APU or a Sandy Bridge ceepeegeepee, can you disable the onboard GPU using BIOS or some such? And, if so, does it actually cut power to the GPU portion or just leave it at an idle mode?

now that nvidia's out of the chipset business and it's either outdated nvidia integrated gpu or discrete nvidia gpu

actually, all of those ION2 systems have both integrated intel graphics and discrete nvidia graphics

those users are all wasting power to drive unused graphics hardware

so if anyone does complain about running a SB or Llano system with discrete graphics

ask them their opinion on ION2s

[23:52:29]

sphery:

hehe, cool

[23:55:07]

wagnerrp:

sphery: so if i understand that email, we would still store all 16KB (or whatever the limit is) in the database, but only be using the first 767 bytes to generate the index?

[23:55:44]

wagnerrp:

that index would only be used to accelerate duplicate matching, correct?

[23:56:55]

sphery:

yeah... it's basically what we were doing before, but instead of using 341 characters, using only 255

[23:57:25]

wagnerrp:

would there be any way to make the index work on the last <n> bytes rather than the first?

[23:57:27]

sphery:

since before, having a text type column, the DB automatically imposed the character limit on our ops

[23:57:39]

sphery:

pretty sure you can't

[23:57:53]

sphery:

kormoc would know better than me, though

[23:58:20]

wagnerrp:

at least to me, it seems like guide providers that supply excessively long descriptions would tend to have a series writeup, followed by an episode writeup

[23:58:39]

wagnerrp:

so the first chunk might be the same, but the last chunk would be different

[23:58:48]

wagnerrp:

although thats assuming the subtitle wouldnt be sufficient in that case

[23:58:55]

sphery:

yeah, not sure how they look

[23:59:09]

sphery:

some of the pastebins of descriptions I've seen were basically walkthroughs of the entire episode, though

[23:59:13]

wagnerrp:

if dekarl is still around, he might have some input

[23:59:24]

sphery:

"Then Bob opens the door and see Mary..."
