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.<\/p>\n
== Steps to reproduce ==
\n1. Follow the steps in [1] to enable VA-API.
\n2. Open a Youtube\/Twitch video (for instance https:\/\/www.twitch.tv\/rifftrax), press play<\/p>\n
== What I expect to happen ==
\nFor the video be played without issues (as it did with Firefox 78).<\/p>\n
== What happens ==
\nAfter 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) or (Youtube). 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.<\/p>\n
== Other info ==
\nA fix is apparently already in the works upstream [2].<\/p>\n
