choppy playback on new danish dvb channels

Denmark finally closed down analogue tv broadcast and most new channels
transmitted in H264 mpeg4.
I am running an older combined backend/frontend with a turion processor
and 5200FX.
At first I was only able to view the HD channel (on my desktop pc/core2
3GHz/8800GT) transmit 720p until I today figured out to installed new
codec for the lower resolution.
When I view the channels with mythtv the play back is very choppy but
the strange is that it seems the framerate is good enough but the
problem is that it seems the frames not played in proper order giving a
very choppy playback especially when a lot of movement in picture.
The playback problems are alike in both h264 704x576 50fps and 1280x720
100fps.
The strange is that vlc can play back without these problems while
mplayer has same problems as mythtv.

I have no idea how to proceed from here I googled for other with similar
problems but without luck so. I hope any of you guys can give me
directions how to find the problem.

What version of myth are you running? There are huge improvements in
0.22 in terms of handling h264.

You could also consider getting a vdpau capable video card (unless
your only choice is AGP).

If VLC does NOT need this, I think it's circumventing the problem.

Maybe true. I have seen people say before that VLC will play stuff
that myth will not. Often a function of CPU/processing power and/or
the state of the VLC code vs the mythtv code. Often the processing
power is enough to decode via VLC but not enough via myth. myth seems
to come with a penalty in terms of its complexity as compared to
'lighter' software like VLC.

I have also seen vdpau fix such problems.

First step is for the OP to tell us what version of myth he is using
and see if an upgrade fixes the problem.

I am running mythbuntu 9.10 which run mythtv version 0.22. On my desktop PC which I use to show HD channel I do not think it is a performance issue (E6850 3GHz/8800GT). mplayer have exactly same problems and if I slow down the playback of a recording I see the same issue that frames seems to be player in wrong sequence (guessing wrong codec).

VLC report following codec info:

Have you tried using VDPAU?
There was a post on the danish xmltvdk list by someone who had given up on
using 0.22 on H.264 and instead uses MythBuntu + MythTV 0.21 with some H.264
related patches. That solution has been reported to work by at least two
persons on the list.

Re: choppy playback on new danish dvb channels [In reply to]

I am also running Ubuntu 9.04 and 0.22 trunk with same troubles with the new
hdtv h.264 dvb-t streams.

If some h.264 patches can solve this - the problem seems to lie with the
decoder libraries - which are MythTVs ffmpeg implementation?

I will search for h.264 patches, but now I'm 0.22 and its tricky to go
back...

Re: choppy playback on new danish dvb channels [In reply to]

I tried trunk with VDPAU too now - not any better. same weird sequence
problems, like the whole picture is dancing the wrong way.

What were those patches for 0.21 ? anyone ?

Have a read on the mplayer-users list, talking the same kind of
problems. Search [MPlayer-users] MPEG-TS + H264 (again)

Michael, Martin,

Please try the following patch for 0.22 and report back. It is planned to go in for the 0.23 release.

Re: choppy playback on new danish dvb channels [In reply to]

I tried patch against 0.22-fixes and trunk same results both with standard
(XV) and with VDPAU. It's still jerky - but it seems to be jerking in the
right sequence anyway.
Got anymore patches ? ;)

I am using the Ubuntu/Mythbuntu binaries so I would need to setup svn build first and I am not sure I get the time to do it this weekend.

Martin,

Thanks for testing. So it sounds like the patch corrected the ordering issue but it is still choppy? I'm wondering if you have more than one issue here. It would help if you could cut the first 50MB of the video and post to www.filebin.ca so myself and others can do more to debug the problem. You can run the following to generate the 50MB sample:

dd if=inputfile.mpg of=inputfile_sample.mpg bs=1024 count=50000

Thanks,

Martin,

One more thing to try. With the reordering patch applied please use VDPAU and increase the VDPAU video buffers using the method described here:

http://svn.mythtv.org/trac/ticket/7405

Thanks,

As suggested by Taylor, can someone please upload a sample clip and
create a ticket on trac. That way I can actually see what's going on
and not forget about it :)

thanks and regards

Mark

Re: choppy playback on new danish dvb channels [In reply to]

I uploaded a clip: http://filebin.ca/qqgbod/tv_sample.mpg

I tried NUM_VDPAU_BUFFERS=40 and no difference.

I may have been a bit hasty in saying that the jerking is in right sequence
- when I play the exact same clip, it still jerking forward and backward
abit - I think its different after the patch, but its hard to see with all
the jerking.

Re: choppy playback on new danish dvb channels [In reply to]

I would like to add a me too but it on french dvb channel
the stream is identified as follow by ffmpeg :
Input #0, mpegts, from 'out.mpeg':
Duration: 00:00:15.19, start: 64935.518456, bitrate: 5390 kb/s
Program 1
Stream #0.0[0x140]: Video: h264, yuv420p, 1440x1080 [PAR 4:3 DAR
16:9], 50 tbr, 90k tbn, 50 tbc
Stream #0.1[0x14a](fra): Audio: eac3, 48000 Hz, 5.1, s16, 256 kb/s
Stream #0.2[0x14b](qaa): Audio: eac3, 48000 Hz, stereo, s16, 128 kb/s
Stream #0.3[0x154](fra): Subtitle: dvbsub
Stream #0.4[0x155](fra): Subtitle: dvbsub

It plays flawless with vlc. I tried with / without VDPAU, with the
patch #3 of the ticket 7252 without success.
a sample file has been upload here :
http://gui.membre.free.fr/mythtv/tv_sample_m6hd.mpg

For information, h264 samples found on the web like trailers from
spider man 3 play perfectly in mythtv.

My systems are :
- Proc Q6600 with a geforce 7600 Gt running debian sid with mythtv
0.22 fixes r22772, NVidia drivers 190.42
- Atom 230 with a Geforce 9300 running debian sid with mythtv 0.22
fixes r22772 with VDPAU, NVidia drivers 190.42

Martin,

Thanks for creating the ticket. The FFmpeg developers are currently working on a solution. I've attached one of the proposed patches by cehoyos to the ticket. Please try and report back to this thread.

Re: choppy playback on new danish dvb channels [In reply to]

Yes worked for me as well. I have some problems compiling with -enable-libfaad and get vdpau to work with my own compile but thats another story.

Hi,

Not wanting to hijack another thread, but is this purely a problem with (danish) dvb? I'm getting occasional video glitsches in hd-pvr files created from a motorola ip cable box (Norway, altibox). It's not enough to call frame skipping (which I had on my movies before applying the framerate-refreshrate fix), and nothing showing up in backend or frontend logs, but noticable and irritating. Looks like a ripple in a frame here and there. Could it be the same issue? I'm using 720p with vdpau (9400 GT). Turning up the cpu freq. (dual core opteron 2,4GHz) doesn't make any difference.

Cheers!

Marius

Marius,

Your problem doesn't seem likely to be the same. This thread concerns a playback problem specific to recent changes by Danish and French broadcasters and their h264 encoders. The best way to get help is either start a new thread or ticket and provide a sample showing the issue as they did for this problem. Please also provide your VDPAU details such as Nvidia driver version, composite extension disabled or enabled, amount of video memory, MythTV version, etc.
