Comment 3 chao.a.chen 2012-08-10 00:44:26 UTC 
I tried to decode all the frames of a video but, failed. From the dump log, I found that one frame's info lost. I cannot find out which frame is lost. So I need  your help.

About The gstreamer's version, I installed them by the apt-get of ubuntu 12.04. And that is confirmed 0.10.36.1.

About the source file, I attached it here(id=220846). Thanks.

we add "printf("  %s, %s, %d\n", __FILE__, __FUNCTION__, __LINE__)" in the function "vaPutSurface", then play a 50-frames MP4 file with gst-launch, and there are 49 vaPutSurface print in log, so it seems gstreamer lost 1 frame. 
if playing raw video files, gstreamer lost more frames, about 15 frames. we have filed another bug: ID 681492

we used mplayer on the same driver to decode, there isn't any lost frames.

Looks like all frames are demuxed and decoded fine, so I guess you need to look into where they are dropped at the sink.

a GST_DEBUG=*sink:5 log might tell you.

Is this related to https://bugs.freedesktop.org/show_bug.cgi?id=54715 ? If yes, can this bug be closed?
Comment 8 Tim-Philipp Müller 2012-09-21 11:08:22 UTC 
Closing this bug, as I understand the issue was actually in gst-vaapi/libva. Please re-open if this is not the case, thanks.
