[09:18:25] markk_: peterbennett: I think I've worked out how to get openmax to draw direct to egl images (i.e. opengl textures). if I get this working, we could then have the choice of openmax->egl_render or openmax/ffmpeg->normal opengl render for raspberry pi. Could we then remove the softblend and egl osd overlay?
[09:20:23] markk_: egl overlay is a royal pain in the backside and softblend for pi osd will shortly be the only osd option that drives a lot of code in videooutbase. egl_render will require Qt to be using an egl backend – not sure what is the norm at the moment on the desktop.

[09:38:05] stuarta: markk_: i certainly think openmax->egl_render is the way forward (i am of course making the assumption we can get the OSD to render properly in that scenario)
[09:38:36] stuarta: markk_: question, is that with the broadcom egl, or the opensource egl

[09:39:33] markk_: stuarta: eg_render is a broadcom openmax component
[09:39:48] stuarta: ah
[09:39:52] stuarta: just found this https://wiki.qt.io/RaspberryPi2EGLFS
[09:40:24] stuarta: not sure i like it tho
[09:40:27] markk_: if we render via egl we get opengl frames out – which means it will just plug into the existing opengl video rendering – with normal osd etc
[09:40:34] stuarta: \o/

[09:43:09] stuarta: what i'm unsure of, and suspect won't work, is broadcom openmax -> opensource opengl
[09:45:23] markk_: stuarta: who knows? I've been using eglfs for all my testing on pi so far. I do wonder whether egl_render will be much faster than straight opengl rendering. as the pi has shared memory, there may not be that much of a difference.
[09:45:39] markk_: going to upgrade to a p3b++++ to test...
[09:45:43] stuarta: does that skip X and render direct?
[09:46:39] stuarta: they are pretty cheap :)
[09:47:16] markk_: with eglfs? yes – no x required. pretty sure that's what the likes of kodi do for their pi builds

[17:25:30] gigem: dragonian: DataDirect support is going away so your only choices are xmltv json with and without sqlite.
[17:30:25] gigem: I had another case (actually two) last night where the backend tried to stream a recording from the wrong directory. The good news is the FileTransfer fix prevented the backend deadlock. The bad news is the backend remains confused about where the recording is located until it is restarted.

[22:56:06] gigem: peterbennett: Building.
[22:56:53] markspieth: peterbennett: I will test too. Have to swap NDKs and rebuild all (again :-) )
[22:57:37] dragonian: gigem: is there a good switching howto? imho, there is far too much out of date instruciton
[22:58:56] gigem: dragonian: In the wiki.
[22:59:38] dragonian: and i could not for the life of me get the DD & astc scanned channels to be matched up. I recall this used to jsut work. I evenentually gave up and typed xmltv ids in manually
[23:00:34] dragonian: ok. i will try it.
[23:03:12] gigem: Now this looks wrong. rwagner essentially copied GetPlaybackURL from programs/mythbackend/backendutil.cpp into libs/libmythprotoserver/requesthandler/fileserverutil.cpp. He made recordingPathLock static in the new location but not recordingPathCache. An unlocked cache update could have caused the wrong location problems I've been seeing. I don't know of anything that would be using the services API when
[23:03:14] gigem: the problems have occurred, though. Still, I think the cache is central to the bug. Time to add more logging there and wait for the next occurrence.
[23:04:34] gigem: dragonian: The xmltvids are quite similar between DD and SD. If you know what you're doing, it's easy to automate the change.
[23:12:36] peterbennett: markspieth: I could not see your problem with a wrong frame displayed while running at 1.2x speed.
[23:15:43] peterbennett: markspieth: Also the other problem with 1080i 25fps, I don't think I have any 25fps interlaced to test.
[23:16:44] jpabq: The only time I see an ugly/wrong frame is when skipping around, and that only happens with interlaced content. It is jarring, and it did not used to do that. I believe that behavior started about a year ago, and I assume it is due to the way the 'hardware' deinterlacers are being fed fields.
[23:16:48] peterbennett: markspieth: A problem with speedup on shield is that it still gets doubled frame speed. With normal linux deinterlace it switches to single frame deinterlace when speeding up.
[23:17:44] peterbennett: jpabq: There is a bug in the shield that shows a wrong frame after a jump.
[23:18:08] jpabq: peterbennett: I see it on VDPAU with my nVidia 1050 as well.
[23:18:11] peterbennett: jpabq: If you use software decode for mpeg2 you should not see that
[23:18:38] jpabq: I do use software decode, but I use VDPAU for rendering.
[23:19:20] peterbennett: jpabq: I found softwrae decode plus vdpau render is bad, with software decode I use Opengl render
[23:19:57] peterbennett: There seemed to be various glitches using software decode nd vdpau render
[23:22:43] jpabq: I will try OpenGL. Last time I tried it, it was too slow to handle timestretch, but that was a long time ago.
[23:23:48] peterbennett: jpabq: Maybe – I do not use timestretch.
[23:28:12] jpabq: In production, I am currently running master from right around the time of the fixes/30 cut. Is there anything to caution me from bringing my production up to currest master?
[23:41:48] peterbennett: jpabq: Not that i am aware of
[23:42:29] peterbennett: jpabq: There have been some reports of live tv handing the backend.
[23:42:55] peterbennett: hanging
[23:59:46] gigem: jpabq: Software decoding has come a long way. I don't know when it happened but I suspect the multithreaded decoding finally matured. Even my lowly ChromeBox can do a decent job at software decoding.
