I updated a year ago or so to the VC4 driver and never looked back. However, I need to use accelerated video playback on a project, and I don't want to go back to the closed BRCM stack!
So I have built latest MESA (18.1.4 as of today), I am using the latest rpi-update kernel (4.14.54-v7+ as of today), and I am ready to build MPV or a similar solution. I need it to work without X11, using KMS/DRM.
So, I have seen that MMAL is the API for abstracted media playing acceleration, but I don't know if it MPV supports KMS/DRM output to start with, and I don't know if acelerated media decompression works without the BRCM stuff yet. So, is it possible at all as things are? (I take OMXPLAYER uses the BRCM stuff, and fkms overlay is not an option).
