Title:
Hardware-accelerated video decoding (VA-API) broken in Firefox 79
(Wayland)
Status in Mozilla Firefox:
Fix Released
Status in firefox package in Ubuntu:
Triaged
Bug description:
After updating Firefox from 78 to 79, hardware-accelerated video
decoding no longer works properly in Wayland: streaming video gets cut
off with an error message from the service.
== Steps to reproduce ==
1. Follow the steps in [1] to enable VA-API.
2. Open a Youtube/Twitch video (for instance https://www.twitch.tv/rifftrax),
press play
== What I expect to happen ==
For the video be played without issues (as it did with Firefox 78).
== What happens ==
After playing for a while (anything from just a few seconds to a couple of
minutes), the video stops and is replaced by a service-specific error message,
such as error #3000 (in case of Twitch). Even when playing, the video also
flickers green. After reloading the tab, the video again plays for a few
seconds before the error message reappears.
== Other info ==
A fix is apparently already in the works upstream [2].
