So I've been thinking about this more....

We're not going to run the web process with --device=all (or --filesystem=, which could also be used to mount /dev/video* devices).
I'm thinking nobody has yet considered how hardware-accelerated video decoding is supposed to work for Flatpak applications. If access to /dev/video* is not security-sensitive, then Flatpak should just mount it automatically IMO. But I'm guessing it's moderately-sensitive, in which case a new permission, say --device=video, would make sense: we would use the new permission when launching the web process, then it would work if the application itself also uses the same permission. Another option *might* be a new desktop portal, but I'm thinking that's probably not suitable for this.
