| [08:00:18] | Roklobster: | mythtv is very well behaved. i can't complain of any issues for a long time |
| [08:00:28] | stuarta: | \o/ you on 0.28 now? |
| [08:00:33] | Roklobster: | been for ages |
| [08:00:43] | Roklobster: | ~ 18 months on 0.28 trunk |
| [08:01:09] | Roklobster: | i have a new mobo to replace the ancient 8 year old athlon so will put mythbuntu 16.04 on |
| [08:01:27] | Roklobster: | simply to support h.265 <cough> |

| [08:13:29] | Roklobster: | nice, well i have a g4400 processor so it should be fine. |
| [08:13:48] | Roklobster: | just need to find the time to descend into mythtv setup hell... |
| [08:14:47] | Roklobster: | lirc, dvb tuners, shepherd, hdmi audio... etc etc etc |
| [08:15:38] | Roklobster: | does vaapi do deinterlacing as nice as vdpau? |
| [08:15:42] | Roklobster: | i bet jya says no |
| [08:15:53] | Roklobster: | ;) |
| [08:28:46] | stuarta: | ENOTIMPLEMENTED |
| [08:29:01] | stuarta: | the hardware and the interface can, we just can't use it |
| [08:29:13] | stuarta: | nobody has sat down and done the work |
| [08:29:47] | Roklobster: | you reckon 3lines of code? |
| [08:29:56] | Roklobster: | this could be my big monment... |
| [08:33:59] | stuarta: | hah :) |
| [08:36:02] | Roklobster: | dunno if mrs lobsta would appreciate the hacking inteerrupting tv recordings |
| [08:40:13] | stuarta: | dev box ;-) |
| [08:40:53] | jya: | Roklobster: what am I saying no to? |
| [08:41:14] | stuarta: | i have both dev and prod backends on the one system, with 2 dual tuners (2x dvb-s2, 2x dvb-t) split between them (so both have the same setup) |
| [08:41:29] | stuarta: | and an old laptop which is my dev frontend |
| [08:41:34] | jya: | Roklobster: the new vaapid API has a full new range of deinterlacers, however we support none, and they are only supported on intel >= 3 years old |
| [08:41:44] | stuarta: | jya: vaapi based deinterlacing. |
| [08:42:26] | jya: | i have a mac mini 2011 with a crappy amd 6630M, thought I would use it for mythtv frontend, but the vdpau code segfault instantly |
| [08:42:29] | jya: | need to check on why |
| [08:42:48] | jya: | i moved to a linux laptop as my primary machine, will resume coding soon |
| [08:43:18] | jya: | stuarta: only bob deinterlacing though, so you lose half of the vertical resolution |
| [08:44:05] | stuarta: | i have the relevant hardware, but not a clue where to start. |

| [08:57:34] | jya: | Couldn't figure out how to get ubuntu to recognise the video card. fedora 24 recognise it first go... then I used the exact same kernel as in fedora. still getting driver errors and xorg segfault |
| [09:01:12] | stuarta: | must be driver differences then |
| [09:17:44] | Roklobster: | jya: once i get my g4400 cpu in i'll be a willing guinea pig |
| [09:18:40] | jya: | stuarta: I copied the kernel from the fedora one, except it boots into the ubuntu / partition |
| [09:18:50] | jya: | don't see how there could be a difference in drivers |
| [09:19:20] | jya: | plus the 6630M is old, released end of 2010 |
| [09:19:29] | jya: | surely ubuntu 16.04 would have sorted those by now |
| [09:22:37] | stuarta: | you would think so |
| [09:23:18] | stuarta: | that reminds me, time to upgrade the frontend to 16.04 |
| [09:25:00] | stuarta: | which btw, has a Intel HD 4400 in it |
| [09:25:10] | stuarta: | and work perfectly with 14.04 |
| [09:39:01] | ** stuarta upgrades prod frontend to 16.04 ** | |
| [09:39:11] | stuarta: | might even be 16.04.01 |
| [10:06:40] | Roklobster: | The G4400 has the Intel® HD Graphics 510. |
| [10:07:44] | stuarta: | ah i was confusing cpu and gpu designations |

| [14:12:42] | ** stuarta ponders adding dbus support for the network being online to the frontend ** | |
| [14:38:20] | stuartm: | ooh, that's a nice idea |
| [14:42:10] | stuartm: | just booted up myfrontend on my TV, no IR connected, without thinking I started pressing the arrow buttons on the TV remote and it moved the selection in the menus ... |
| [14:42:35] | stuartm: | colour me impressed, I'm guessing that CEC just works out of the box for the RPi now, but I missed the memo |
| [14:42:45] | stuarta: | i just upgraded my prod frontend to ubuntu 16.04.01, now it boots up so fast the network isn't ready when the frontend starts |
| [14:43:01] | stuartm: | unfortunately it's just the arrow buttons that worked, select did not |
| [14:44:01] | stuartm: | I now need to see if it's possible for the other buttons to work via CEC, if they can, then I'll be very, very happy |
| [14:44:10] | stuarta: | :) |
| [14:44:18] | stuarta: | you can thank peterbennet for that |
| [14:45:29] | stuartm: | that's a serious check in the usability column for RPi based frontends, just plug them in and you don't need another remote, you don't need to mess with lirc or a keyboard, it just works |

| [14:46:59] | stuartm: | but only if other keys can be made to work, at a minimum you need options menu, select button and playback buttons ... bonus points for buttons like Guide, but I doubt those are part of the CEC spec |
| [14:48:07] | jheizer: | I think you can go in to the key mappings and try to fix them |
| [14:48:25] | jheizer: | sometimes |
| [14:48:37] | jheizer: | IIRC |
| [14:51:08] | stuartm: | right, but for the best experience it should work out of the box and since with something like CEC we can achieve that easily since the actions will be standardised |
| [14:51:26] | stuartm: | I'll play with it tonight |
| [14:51:37] | stuartm: | if I'm not working again |
| [14:55:11] | stuartm: | well I got select working, unfortunately hdmi audio still doesn't work so I won't be using that frontend just yet |

| [19:14:38] | knowledgejunkie: | regarding LiveTV on 0.27+ with a PVR-150, if I want to increase the recording/playback buffer by a second (or two/three), which routines should I attack? Since upgrading a system to 0.27 last year from 0.21, LiveTV is unusable initially (video freezes/stutters) unless I pause it for a second or two, and programme transitions hang the frontend. No probs at all with DVB sources. |
| [19:17:49] | knowledgejunkie: | this is on a Debian Wheezy box (with myth from dmo, not source) that talks to a CRT directly from the ATI video card, so it can't be updated to Jessie due to the UMS->KMS changes. With a 2yo and a 7mo time is a bit limited but it seems odd that LiveTV is broken on this system with a PVR-150 card. |
| [19:21:55] | jams_: | knowledgejunkie, Doesn't address your question but possible solution. Same thing happens with an intel video card but nvidia seems to do ok. With that said overall the pvr/ivtv line of cards did take a big hit with livetv and .27+ |
| [19:50:57] | knowledgejunkie: | jams_: due to the ATI card's ability to generate a valid PAL signal for use with a homebrew VGA->SCART cable, this box is kinda tied to the card. Need a more complicated sync circuit cable for use with older nvidia cards (and then there's no guarantee that it would work...). |
| [19:52:02] | jams_: | figured there was a reason :) but thought it was worth mentioning |
| [19:52:11] | knowledgejunkie: | jams_: livetv does work with the ATI card and PVR-150 *if* I pause playback immediately for a second or so – I just need to know where to bump the buffer/wait. I'm hoping this is also why prog transitions fail so hard. |
| [19:57:50] | knowledgejunkie: | jams_: thx for the idea though :) |
