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…
Yes, mesa have nothing to do with video on arm devices as arm have a vpu unit to handle video encoding and decoding.
Currently @Darksky is testing H265 (HEVC) over kodi 19 which seems to work fine but h264 will be software decoded.
Will the H265 (HEVC) works on Amlogic Bifrost chip?
No dear, rpi uses didnt soc.
Also amlogic bifrost is not used for vpu. Amlogic vdec is used for video decoding.
