[00:01:44] torula: dekarl: is there something better for kodi than Simple IPTV CLient?
[00:01:51] torula: the guide seems to be problematic
[00:02:05] torula: i don't think mythtv will run on a fire stick will it?

[06:03:47] dekarl: I put the APK through the new app testing service from Amazon and it nicely failed on all FireTV, now looking if there is something in the logs.
[06:04:35] dekarl: I was hoping it would output something like "this'n'that must be done so the app shows up in the launcher" but that is not the case :(
[06:21:32] lapion: apparently the 0.28 framegrabber code cannot handle 25 or 30 fps let alone transcode the few received frames into anything useful

[13:41:35] lapion: stuarta, tried a lot of different things but still cannot get more then every so many seconds a frame
[13:45:13] stuarta: the fundamental problem we have is none of the devs have such hardware, so unless users can contribute code to keep it working, it'll die off slowly
[13:50:21] stuarta: lapion: out of interest, which hardware do you have?
[13:52:21] stuarta: and the output of `v4l2-ctl --all` is usually informative too
[13:53:46] lapion: Host bridge: Intel Corporation Mobile PM965/GM965/GL960 Memory Controller Hub (rev 0c)
[13:53:46] lapion: 03:00.0 Multimedia controller: Philips Semiconductors SAA7134/SAA7135HL Video Broadcast Decoder (rev 01)
[13:53:46] lapion: VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (primary) (rev 0c)
[13:54:46] stuarta: so an saa7134
[13:54:57] lapion: pcmcia card
[13:55:05] stuarta: can you pastebin the output of `v4l2-ctl --all`
[13:55:22] lapion: busy installing v4l-utils
[13:55:25] stuarta: :)
[13:55:35] stuarta: heh, my laptop doesn't even have a pcmcia slot

[14:00:45] lapion: stuarta,
[14:07:36] lapion: stuarta, any good ?
[14:14:16] stuarta: sorry was off fetching coffee++
[14:15:25] lapion: Cafeine++
[14:15:26] stuarta: interesting, so you have tried to set this up as a v4l2 device
[14:15:31] stuarta: ?
[14:16:19] lapion: this configuration has been in use ever since 0.23
[14:17:30] lapion: in the beginning with a P4 toshiba// in the mean time with a core2 duo HP.. lastly working correctly under 0.27

[14:18:17] lapion: mplayer plays fine off it..
[14:18:42] stuarta: any logs from when the backend doesn't work right?
[14:19:58] lapion: let me get some logs..
[14:21:33] lapion: shall I record something or do live playback ?
[14:21:50] stuarta: either, live = record and playback
[14:22:03] stuarta: recording is easier to do remotely
[14:22:52] pppingme (pppingme!~pppingme@unaffiliated/pppingme) has joined #mythtv
[14:25:59] lapion: any specific logging options I should pass to the backend ?
[14:26:27] stuarta: from memory --verbose record
[14:29:51] lapion: I have two lines that jump out at me , I'LL them here..
[14:30:51] lapion: "[mpeg4 @ 0x7f7b0000da00] AVFrame.width or height is not set" and "[mpeg4 @ 0x7f7b0000da00] AVFrame.format is not set"
[14:45:05] lapion: I am going to reboot the system mythtranscode has a stale process
[15:00:02] stuarta: woot, fixed 2 different mythweb issues today
[15:00:21] stuarta: must be time to give up
[15:11:47] lapion: is there any way to post a file to pastebin ?
[15:15:03] lapion: stuarta, http://pastebin.com/fwaZ6tMW
[15:16:25] lapion: stuarta, the next is ouput of 2> http://pastebin.com/4X2nQTEg
[15:32:38] stuarta: it does kinda look like it's managing to open the device okay
[15:42:27] lapion: I have tried to change the video profile to one using trjpeg in stead of mpeg4
[15:44:43] lapion: stuarta, I have also tried to use the new v4l2 encoder as a cardtype
[15:44:53] stuarta: how did that go?
[15:45:05] lapion: same result
[15:45:10] stuarta: :(
[15:50:13] lapion: well slightly better
[15:50:28] lapion: I get short video bursts
[15:50:36] lapion: when playing back
[15:52:50] stuarta: like it's only captured short segments?
[15:53:35] lapion: when I play the file in mplayer it plays the audio stream but the video is just a number of single frames
[15:54:14] stuarta: sounds like it's not capturing all the video frames sufficiently quickly
[15:54:16] lapion: about one frame per second
[15:55:08] stuarta: from your v4l2-ctl output, it only has 2 frame buffers, and runs at 25fps, so the backend needs to pull those frames at a minimum of 25fps to avoid dropping video
[16:01:14] lapion: stuarta, when recording with the old v4l method, the resulting video has 2 frames per second, in green only.
[16:01:35] lapion: the v4l2 method gets one fps in a bit more color
[16:01:46] stuarta: ugh
[16:03:13] lapion: of course it might all have to do with the fact that the backend and the player have a significantly bigger memory footprint..

[16:43:51] gigem: lapion: I would look very closely at the setup ioctls that get issued when the framegrabber device is opened and see how they differ from before. That was an area of concern when I removed the multi-input support from the ChannelBase classes.
[16:52:01] lapion: gigem, what do I have to do get you those ioctls ?

[21:22:23] gigem: lapion: Any pastebin should suffice, though, I don't know who can really help analyze them as none of the current developers are familiar with the framegrabber recorder. jpabq is with the v4l recorders that encode in hardware, but I don't know how similar the two are. The main point was for you to be able to identify what is different from before when it worked and now when it doesn't.
