Currently, watching a movie is painful since the software decoding is

too slow and it has very low fps on 1080p (or even 720p or even 480p)

can
be done, but I don't remember what it was, or i didn't find it in my
email/the archives.
Can someone tell me what exactly needs to be done (in kernel) so that
I can
take a crack at it, (hopefully with some help)?
I don't remember if this was relevant, but there was some talk of
needing to
use opengl output with a specific texture format for it to work? or is
that
seperate?
That's something for linux-media. The hardware codec isn't part of vc4
or v3d, it's a separate controller that requires a separate driver (in
v4l2).
That driver isn't upstream, and that would need the first thing to
tackle.

Can I assume you're talking about the vchiq driver, which would have
multiple things including codecs, or am I misunderstanding it?
