FATAL: Unable to load the QT mysql driver, is it installed?

[04:22:20]

[Kid]:

any ideas on this?

[04:24:35]

gregl:

[Kid], is the driver installed? I had the same error last time i compiled and the driver wasn't installed

[04:24:47]

[Kid]:

i believe it is

[04:24:56]

[Kid]:

what is the package name for deb

[04:25:08]

What distro are you using?

[04:26:49]

Debian

[04:27:26]

[Kid]:

synaptic?

[04:27:29]

[Kid]:

[04:27:35]

[Kid]:

just aptitude

[04:28:44]

jya:

stuarta: what is that for?

[10:46:52]

jya:

I mean what is this in reference to?

[10:47:24]

stuarta:

jya: i was reading scrollback and you asked if we could use qt5.7

[10:47:57]

jya:

ah

[10:48:35]

jya:

it was more in relation of being to compile with Qt 5.7

[10:48:42]

jya:

and the answer is yes...

[10:48:57]

stuarta:

oh right, yeah it'll work fine with 5.7

[10:49:01]

jya:

I had to do some tweaks related to the 5.7 requirements of C+11 being enabled

[10:49:11]

stuarta:

feature set wise, we need to be compatible with 5.5

[10:49:40]

stuarta:

btw, shall i get devel/ffmpeg added to the buildslaves?

[10:49:52]

jya:

problem is 5.5 doesn't install on macOS 10.12

[10:49:59]

** stuarta thinks it's worthwhile **

[10:50:16]

jya:

stuarta: you can yes.. I don't foresee much problem, it was the simplest resync I've ever had to do really..

[10:50:26]

jya:

it took me a while, but nothing difficult, just time consuming

[10:50:40]

stuarta:

nice, i was hopeful of that since it was 3.0 -> 3.2

[10:51:03]

jya:

getting myth to compile on 10.12 however, that was another wasted day today. started at 9AM and only got it to run around 4PM

[10:51:13]

stuarta:

ugh

[10:51:52]

jya:

couldn't compile on 10.12 any of the requirements (libcurl no longer supporting SSL), same shit with mysql...

[10:52:26]

jya:

then it's the C++11 because they use a different ABI format in the Qt framework

[10:52:30]

jya:

like, how dumb is that

[10:52:33]

stuarta:

sounds painful

[10:52:36]

jya:

5.7 requires C++11

[10:52:55]

jya:

yet, they set the target framework as 10.8

[10:53:00]

jya:

10.8 doesn't have C++11 runtime

[10:53:05]

** stuarta facepalms **

[10:53:06]

jya:

so it just can't compile

[10:53:26]

jya:

I had to manually modify all the makespec and many headers from 10.8 to 10.9

[10:53:42]

jya:

it's like Qt doesn't even test the binaries they ship

[10:53:56]

stuarta:

that's crappy

jya:

let me have a look

[11:19:17]

stuarta:

http://code.mythtv.org/buildbot/builders/ffmp . . . bit/builds/0

[11:20:08]

it'll throw any further errors in #mythtv-commits

[11:25:32]

stuarta:

well it does if you request it here

[11:26:43]

stuarta:

to keep the noise down i requested it there

[11:30:05]

jya:

stuarta: libfaac support was removed in FFmpeg, they felt that their own AAC encoder was just as good

[11:30:38]

stuarta:

right, so the freebsd configure shouldn't call it

[11:30:43]

jya:

yes

[11:30:45]

stuarta:

lemme check the build definition

[11:30:59]

jya:

I will remove all trace of it, and make sure our aac encoder will continue to work with the new one

[11:31:22]

jya:

very happy with Visual Studio Code on linux

[11:31:30]

stuarta:

really? wow

[11:31:32]

jya:

getting mythtv working there was a breeze

[11:31:56]

jya:

just open the mythtv folder, set up the debugger

[11:31:57]

jya:

done

[11:32:03]

stuarta:

what about any of "--enable-libmp3lame" "--enable-libx264", "--enable-libvpx" "--enable-libxvid", "--enable-nonfree" ??

[11:32:47]

stuarta:

they all still good?

[11:32:52]

jya:

yes

[11:32:57]

stuarta:

ok

[11:33:01]

jya:

mp3lame is still supported

[11:33:11]

jya:

there's no other h264 encoder, and same for VP9

[11:33:22]

jya:

only libvpx supports vp8/9 encoder

[11:33:46]

jya:

xvid okay (or we using it anywhere?)

[11:34:06]

stuarta:

doubt we are using it, but that's what's on the configure line

[11:40:06]

stuarta:

removed libfaac from the freebsd configure line, just waiting for the other builders to finish before I reload that

[11:40:16]

stuarta:

s/that/the build master/

[11:40:17]

jya:

stuarta: do you have an encoder setup to use AAC (like hls?) ?

[11:40:25]

stuarta:

me, no

[11:45:30]

jya:

ok.. aac encoding should still work

[11:45:39]

jya:

the AAC encoder is searched by name "aac"

[11:45:47]

stuarta:

well the windows build broke, we'll need dblain to decipher that one

[11:46:16]

jya:

ah no

[11:47:25]

jya:

https://github.com/MythTV/mythtv/blob/master/ . . . ode.cpp#L499

[11:48:07]

jya:

we could drop libmp3lame then

[11:48:12]

stuarta:

\o/

[11:48:15]

jya:

it was only used if libfaac was configured

[11:48:28]

jya:

was 1-libfaac, 2-mp3lame, 3-aac

[11:48:48]

jya:

so we don't have 1, but have 3 which is now as good as 1 was

[11:48:56]

jya:

so I think we should go with aac all the time

[11:49:09]

jya:

we should work on making all of that more open source

[11:49:19]

jya:

aac, h264, h264, beurk

[11:49:23]

stuarta:

is that the only place we use libmp3lame?

[11:49:24]

jya:

opus all the way

[11:49:29]

jya:

let me check

[11:49:47]

stuarta:

because I remember raising a ticket to remove mp3lame as a build requirement

[11:49:52]

jya:

VS Code says that's the only place libfaac is used :)

[11:50:03]

** stuarta does a happy dance **

[11:50:23]

stuarta:

hatchet time

[11:50:35]

jya:

same for CONFIG_LIBMP3LAME_ENCODER

[11:52:17]

stuarta:

#12019

[11:52:17]

** MythLogBot http://code.mythtv.org/trac/ticket/12019 **

[11:53:05]

stuarta:

at absolute minimum we move #3 up to #1 and downgrade mp3lame to optional

[11:53:05]

** MythLogBot http://code.mythtv.org/trac/ticket/3 **

[11:53:05]

** MythLogBot http://code.mythtv.org/trac/ticket/1 **

[11:53:19]

stuarta:

but tbh, it might be time just to throw mp3 lame away

[11:54:31]

jya:

there's no method right now to set something as option

[11:54:34]

jya:

al

[11:54:41]

jya:

ah, my bad there is

[11:54:54]

jya:

there's an option HLSAUDIO

[11:55:11]

jya:

set by Chris Pinkham 59 months ago :)

[11:55:12]

stuarta:

what i meant is in configure, rather than erroring if lame isn't found, continue, then the conditionals in the code will "just work"

[11:55:44]

jya:

i'm going to drop that, aac always

[11:55:52]

stuarta:

fbm

[11:55:59]

jya:

fbm?

[11:56:04]

stuarta:

Fine By Me

[11:56:10]

jya:

ok

[11:56:21]

stuarta:

and we get to close the above ticket

[11:56:21]

jya:

you can enable libmp3lame

[11:56:27]

jya:

because ffmpeg does support it

[11:56:57]

jya:

going to drop this HLSAUDIO option too... aac always

[11:57:02]

jya:

it's only used for HLS that code

[11:57:09]

jya:

all devices supporting HLS support aac

[11:57:54]

stuarta:

yay, first green build in

[11:58:15]

stuarta:

debian jessie too

[11:58:39]

stuarta:

hopefully the rest won't take too long

[11:58:41]

jya:

I'm going to remove VDA support too and move to Apple VT instead

[11:58:57]

jya:

it can do both software and hardware, and I don't see the point of supporting 10.6 anymore

[11:59:13]

jya:

i think i dropped support for anything < 10.8 anyway when 0.28 came out

[11:59:37]

stuarta:

makes sense, even craig's builds target only the new stuff now anyway

[11:59:49]

stuarta:

+i think

[12:04:11]

jya:

stuarta: what's your libmp3lame bug #?

[12:04:41]

stuarta:

#12019

[12:04:41]

** MythLogBot http://code.mythtv.org/trac/ticket/12019 **

[12:08:13]

jya:

in reference to this bug, I see no code related to libmp3lame other than in the hls encoder

[12:08:58]

stuarta:

you had some earlier comments about the analog encoder using it

[12:09:04]

stuarta:

but tbh, analog is dead

[12:09:29]

stuarta:

and the "modern" analog capture cards do the encoding for you

[12:09:38]

stuarta:

there's hardly any "lamegrabbers" left

[12:10:17]

jya:

oh i see something related to mp3 encoding in the nuppelencoder

[12:10:51]

stuarta:

i vote for: no lame -> disable nuppleencoder

[12:11:13]

stuarta:

there by making it optional

[12:11:40]

jya:

i don't see where it does encoding in there

[12:11:50]

jya:

been too long since i've looked at this code

[12:12:59]

stuarta:

phase 1 drop the previous one you noted in the hls transcoder

[12:13:10]

jya:

looking at V4LRecoder

[12:13:19]

stuarta:

that code is horrible

[12:13:19]

jya:

looks like it doesn't use mp3lame either

[12:13:28]

jya:

did the cards have a HW mp3 encoder?

[12:15:04]

stuarta:

i dunno what they have

[12:15:21]

jya:

oh i see

[12:15:33]

stuarta:

https://paste.fedoraproject.org/480987/79125714/ <- that's the webcam on the laptop

[12:15:36]

jya:

it wasn't using ffmpeg for lame encoding

[12:15:42]

jya:

but libmp3lame directly

[12:15:44]

stuarta:

even that seems to do some stuff

[12:16:11]

stuarta:

suspect it's just raw frames it throws out

[12:16:24]

jya:

ok so i need to redo...

[12:16:38]

jya:

will split aac / mp3 stuff, had done it all in one codec

[12:18:15]

stuarta:

thanks for your work on this, it's appreciated

[12:18:57]

jya:

was long overdue

[12:19:11]

stuarta:

yep

[12:48:58]

enyc:

(aside): — I notice osuosl have ipv6 of sorts, test address ipv6.osuosl.org incl. reverse dns ... I wonder if support-request to enable ipv6 on all the mythtv-parts would be of any use =)

[12:50:44]

enyc:

want to avoid unpredictable ipv6 'auto' address, and get correct forward-confirmed reverse-dns, so email sending works etc...

[12:56:30]

stuarta:

i've been chasing them for ipv6 for a while

[12:56:50]

stuarta:

it's move from being "on the university" to "on us (ie.osuosl)"

[12:58:02]

stuarta:

might be time to open a support ticket asking for ipv6 address(es)

[12:59:14]

yes... just make sure you get reverse dns worknig before outgoing mail lists use it...

Hi. To be more uptodate during my tests i would like to switch from "fixes/0.28" to git master. I noticed, that a DB update would be done then (automatically). Is it lateron possible to switch back and forth between fixes/0.28 and master without DB corruption? Would that even work?

[19:18:15]

kukks:

Or is it even better to start with a fresh DB when using master?

[19:21:10]

stuartm:

it's not always possible to move back. When you upgrade a backup will be taken, but if you roll back to the backup then you'll lose any changes (including recording metadata) which happened post upgrade

[19:23:20]

stuartm:

there's no need to start with a fresh database, it all depends what you're aiming to do. If this is a production setup and you don't want to lose data about recordings etc then think carefully, but if that stuff doesn't matter to you then there's not a lot to lose except the time you'll spend on restoring the backup (if necessary)

jya:

stuarta: i thought windows compilation got broken, but the failures aren't related to the myth code but the dependencies.

[23:22:05]

jya:

there's also no windows builder for master. so can't tell if a regression got introduced or not
