2.1.2, crash using vaapi or vdpau hw accel for decoding

opensuse 13.1 x86_64 vlc 2.1.2

i use freebox.luac to access to tv stations via internet these stations are broadcasted by my isp "Free"

if vlc uses vaapi or vdpau for hw accel decoding it works well but when switching from a tv station to another then vlc disappears totally

if vlc uses no hw accel decoding then no pb

Symbolic strack trace is needed for crash reports.

additional info :

with the fisrt tv station displayed there is no pb . vlc does not crashes . the hw accel with gpu works well for a hd stream . displaying a hd stream consumes 8 % of cpu power instead of 35 % without gpu accel .

vlc crashes when switching to the second tv station (any of the list)

by default vlc choose vdpau for decoding

i display only mp4 stream , for example :

Flux 0 :

• type: Videos
• Id original: 68
• Codec : H264 - MPEG-4 AVC (part 10) (h264)
• Résolution : 720x576
• Débit d'images : 25
• Format décodé: Planar 4:2:0 YUV

Not really. The crash occurs when stopping the accelerated decoding according to the stack trace. libavcodec tries to free the picture too late.

This is most certainly a bug in your version of libavcodec, since VLC has flushed the buffers earlier, such that there should not be any remaining pictures when avcodec_close() is called.

Could you install ffmpeg-debuginfo (I hope this is the right package) and post a backtrace for the VDPAU crash?
