can someone point me to more informations about video acceleration under the raspberry pi 4 and aarch64. Maybe a link to a github repo or the name of a kernel subsystem. I know it is not available at the moment, but where is it implemented? I think it is not mesa. Will it be in kms or v4l2?
You sure? I think mesa is “only” for accessing the 3d pipeline via opengl es or vulkan. The video hw decoding blocks are unaffected by this. I would think it is more in the v4l2 direction…
