I'm increasingly excited about what #opencl support coming together across the board in #mesa could mean for multimedia in the free ecosystem.

Just some thoughts about what I think is on the table:

• fluent/efficient AV1[1] playback across the board, maybe even on hardware like the Raspberry Pi4

• real-time AV1 encoding in reasonable quality for video chat, screencasting and camera recording

• a GPU ISP, allowing reasonable image quality with any camera sensor

1: or any other format?

This is probably over-optimistic - but seeing what's being done with CUDA on that other platform, how dmabuf and kms are evolving and how gl/vk support came together in Mesa - it might be somewhat realistic?

Hm, looks like I was wrong about de- and encoding parts and it's actually hard to speed those up with opencl. One claim I read was that modern codecs are just too branchy and CPU ends up being better - does anyone know more about that, specifically regarding AV1?
