Thank you for your bug report. Is that a specific webm video or any video in that format? Is playing /usr/share/help/fr/gnome-help/figures/gnome-launching-applications.webm for example working for you?
If that's only one could you attach an example maybe to the report?

[corrado venturini (corradoventu)]

Problem occur with ALL the videos created by a trail camera in AVI format and converted to webm using ffmpeg. Problem does NOT occur with the videos created by a DIFFERENT trail camera in AVI format and converted to webm using ffmpeg.

The file you link does not exist:
corrado@corrado-n2-mantic:~$ cd /usr/share/help/fr/gnome-help/figures
corrado@corrado-n2-mantic:/usr/share/help/fr/gnome-help/figures$ ls
tile-software.svg ubuntu-logo.png
corrado@corrado-n2-mantic:/usr/share/help/fr/gnome-help/figures$

Attaching totem debug output
will also attach a video causing the problem

[corrado venturini (corradoventu)]

Attaching also ffmpeg output

[Sebastien Bacher (seb128)]

Thanks for the log and video example, it confirms that the issue is due to gstreamer-vaapi, the video plays fine without gstreamer1.0-vaapi installed

[corrado venturini (corradoventu)]

Problem does not occur with gstreamer1.0-vaapi: Installed: 1.24.2-1
