backtrace

[Comment 8 Alexis Ballier 2013-03-13 16:41:02 UTC]

could you try to see if your problem persists with ffmpeg-1.0.5?

[Comment 9 dolohow 2013-03-13 18:34:29 UTC]

On ffmpeg 1.0.5:

Too many buffered pts
[h264_vdpau @ 0x7fa232be9d00]VDPAU decoding does not support video colorspace
[h264_vdpau @ 0x7fa232be9d00]decode_slice_header error
[h264_vdpau @ 0x7fa232be9d00]no frame!
Error while decoding frame!

but I switched from vdpau to gl and it's working

[Comment 10 Alexis Ballier 2013-03-13 18:47:54 UTC]

its likely vdpau isnt supported for you movies

what does mplayer ran from command line prints ?
please attach a sample.

[Comment 11 dolohow 2013-03-13 18:55:30 UTC]

I did attached the sample, see previous comment.
Apart from that there also warning that I'm running slow machine.

[Comment 12 Alexis Ballier 2013-03-13 20:40:37 UTC]

hmm, no, there is no video sample as far as I can see :)

[Comment 18 Alexis Ballier 2013-03-15 11:00:16 UTC]

Thanks, I've been able to reproduce your problem but unfortunately I have no clue how to fix this :-(
Could you please report it upstream (with the backtraces from mplayer-9999 and ffmpeg-9999)?
http://ffmpeg.org/bugreports.html for guidelines
and: https://ffmpeg.org/trac/ffmpeg
for the bug tracker
since you have a small sample, that should help them.

Also, I don't think you can reproduce this bug with the ff* tools since those do not support vdpau, so you'll have to mention mplayer and provide these logs and backtraces (don't worry about ffmpeg 0.10* they will want -9999)

[Comment 19 dolohow 2013-03-18 20:22:38 UTC]

Looks like it's not a ffmpeg bug, because ffplay can play this file.

ffplay doesnt use vdpau afaik, so that's quite normal if it plays fine with mplayer without vdpau :)

[Comment 21 Alexis Ballier 2013-07-29 21:40:34 UTC]

please test with mplayer-1.2_pre20130729. It doesnt seem to segfault anymore but will simply not play the video. My guess is that your vc= options are wrong.
