Public bug reported:
On a Ubuntu 18.04 (amd64) laptop, all H264 videos read by Totem display a green
screen (but the audio is fine, and the subtitles are displayed above the green
screen). VLC reads them properly. Totem reads them properly on another Ubuntu
18.04 computer.
If I remove the package gstreamer1.0-vaapi, the videos are read properly.
If I install it back (version 1.14.1-1~ubuntu18.04.1), the videos are green
again.
There is no error message in the kernel log, or in the standard output of Totem.
I suppose the hardware decoding is failing?
All the packages are up-to-date.
The laptop is a Lenovo X201 with a Core i5 M 540 CPU, with no other
graphics card.
All videos should be read properly (with hardware acceleration if
possible, but it should fallback to software decoding if something goes
wrong).
