I discovered to my dismay that Gnome Web, when installed as a Flatpak, stopped using hardware-accelerated video decoding at some point. Previously, this was achieved via VAAPI gstreamer plugins.
However, those plugins seem to have been deprecated and no longer enabled in the Flatpak runtime. When I asked the Gnome Web developers, they said new VA gstreamer plugins are in the works, but they aren’t ready yet.
So my question is, is there a way to reliably have hardware-accelerated video (decoding) in Flatpak apps right now?
Thanks in advance.
