#2915 new defect

mpeg2 vdpau hardware decoding does sometimes not work with libavformat mpeg2 demuxer, but always works with mplayer mpegps demuxer

Reported by:	gjdfgh	Owned by:
Priority:	normal	Component:	avformat
Version:	git-master	Keywords:	vdpau
Cc:		Blocked By:
Blocking:		Reproduced by developer:	no
Analyzed by developer:	no

Description

Sample file:

http://www1.datafilehost.com/d/27de60ea

Working playback:

mplayer -vc ffmpeg12vdpau -vo vdpau -demuxer mpegps vdpau_pic_broken.vob

Broken playback (blocks all over the place):

mplayer -vc ffmpeg12vdpau -vo vdpau -demuxer lavf vdpau_pic_broken.vob

This also happens with various other mplayer forks. MPlayer or ffmpeg versions don't seem to matter. I tested above two test cases with "MPlayer 1.1-4.8 (C) 2000-2012 MPlayer Team" (debian package 3:1.1.1-dmo6 from http://www.deb-multimedia.org/), and could confirm the blocking with my own mplayer fork compiled against a very recent ffmpeg git checkout.

Console output:
