Description Oliver Henshaw 2015-09-23 10:10:05 EDT
Description of problem:

I tried invoking gst-launch-1.0 with similar options to those used by firefox - at least according to https://bugzilla.mozilla.org/show_bug.cgi?id=894372#c8 which is hopefully still current. Playback has no problems without vaapi or with LIBVA_DRIVER_NAME=vdpau or without ximagesink, but:

$ LIBVA_DRIVER_NAME=gallium gst-launch-1.0 --gst-debug=*:2 --gst-debug-no-color playbin uri=file:///home/watcher/Videos/test.mp4 video-sink=ximagesink

Shows no video, just a green square with colored glitches on the very top. Running without software color balance (flags=0x217) still shows no video but now the playback window is pure black.

Both times, the output shows:

Please verify if you can reproduce with gstreamer1-vaapi for f23.
