- h264 video decode failed with assertion and tendency to crash GNOME/GUI
Test h264 clip:
$ youtube-dl -f mp4 <a href="https://www.youtube.com/watch?v=azvR__GRQic">https://www.youtube.com/watch?v=azvR__GRQic</a>
Gstreamer command line
$ gst-launch-1.0 playbin uri=file:///path/to/MP4
or
$ gst-launch-1.0 filesrc location=/path/to/MP4 ! qtdemux ! vaapidecodebin !
vaapisink
Use enhanced-h264ify plugin on Chromium to playback the same h264 video clip
from YouTube.com
Geforce 9300 mGPU - video played as garbage, browser may crash
GT730 - fallback to FFmpegVideoDecoder after asserts
ve4_set_surface_info:969 - unsupported surface format, try
is_format_supported() !
