Description nkef 2013-09-09 13:43:35 UTC

Gstreamer fails when gstreamer-vaapi hardware decoding is used trough vdpau-va-driver with NVIDIA binary drivers with the following error message:

gst-launch-0.10: vdpau_decode.c:1264: vdpau_EndPicture: Assertion `obj_buffer' failed

Example pipeline:
gst-launch-0.10 -vvv filesrc location=test.h64 ! queue ! h264parse ! queue ! vaapidecode ! vaapisink sync=false fullscreen=yes

The bug was produced in Ubuntu 13.10

vdpau-va-driver:amd64 0.7.3-2ubuntu1
libvdpau1:amd64 0.6-2
nvidia-319 319.32-0ubuntu6
gstreamer0.10-x:amd64 0.10.36-1.1ubuntu
gstreamer0.10-vaapi:amd64 0.3.6-0ubuntu4

The bug was also reproduced in Ubuntu 13.04
13.04, with default system packages.

The bug was also reproduced with custom build of gstreamer-1.0.10 and gstreamer-vaapi-0.5.6 in Ubuntu 13.04 using the vdpau-va-driver:amd64 0.7.3-2ubuntu1 

A workaround only applicable to gstreamer-0.10
Example pipeline:
gst-launch-0.10 -vvv filesrc location=test.h64 ! queue ! h264parse ! queue ! vaapidecode use-ffmpeg=true ! vaapisink ync=false fullscreen=yes

The workaround works only up to gstreamer-vaapi 0.3.8. 
From 0.4.0 FFmpeg-based decoders were dropped.

gstreamer vaapi crash while decoding picture

The same happens still in Ubuntu 14.04 with gstreamer 1.2.3 and radeon card.

I'm attaching here the backtrace I'm getting.

The GStreamer project tracks bugs on bugzilla.gnome.org, please re-file any issues there for the gstreamer-vaapi
