Public bug reported: For the linked video, if I try to play it through playbin on Jammy (`gst-launch-1.0 playbin uri=file:///home/floe/Downloads/big_buck_bunny_720p_surround.mp4`), I get only a black window with the audio track playing in the background. This happens for most H.264 encoded videos (which also can't play in Totem, see https://bugs.launchpad.net/ubuntu/+source/totem/+bug/1969512).
Running with GST_DEBUG=3 gives a lot of ``` 0:00:00.381581482 183712 0x7f5f6c05b640 ERROR vaapivideomemory gstvaapivideomemory.c:254:map_vaapi_memory: failed to make image current 0:00:00.381663666 183712 0x7f5f6c05b640 ERROR default video-frame.c:168:gst_video_frame_map_id: failed to map video frame plane 0 0:00:00.381711318 183712 0x7f5f6c05b640 WARN xvimagesink xvimagesink.c:1038:gst_xv_image_sink_show_frame:<xvimagesink0> could not map image ``` This issue can be worked around by uninstalling gstreamer1.0-vaapi package, or by downgrading to 1.16.2-2. vlc seems to be using VAAPI on the same machine & distro without issues: ``` $ vlc big_buck_bunny_720p_surround.mp4 VLC media player 3.0.16 Vetinari (revision 3.0.13-8-g41878ff4f2) [000055cebcc6f580] main libvlc: Running vlc with the default interface.
