We now support playback via openh264 but I'm not sure how that interacts with flatpak sandbox.

Comment 2 Michal Konecny 2020-11-04 09:00:52 UTC
I switched to Flathub Firefox in the meantime, so I'm not sure if the issue is still there.

Comment 3 Mirek Svoboda 2020-11-17 18:28:11 UTC
I am successfully reproducing this issue on my system.

I use a different Twitch video for reproduction, as the video from the issue description is no longer available.
The video currently used for reproduction: https://www.twitch.tv/videos/805606231
