Hope it goes well.

It is true that I do not have access to VPU documentation but the progress is going very well and we have very good support from Rockchip...

More than half a year later, any progress on GNU/Linux video with that "very good support"?
The Odroid N1 (RK3399) has a video on GNU/Linux bug which the community might get fixed but there is also a wayland+chrome bug in the mali driver which can only be fixed by ARM, Rockchip, or someone with a Mali NDA.

I still have hope...

Kodi, mpv and ffmpeg code have landed upstream for drm/kms playback support, unfortunately we have seen video decoding issues with RK 4.4 kernel pushes after https://github.com/rockchip-linux/kernel...e-20171213.

Current focus is mainly around HDR support, all pieces needed for HDR exists in RK 4.4 kernel but there is a chicken or the egg problem in that we do not want to add vendor specific HDR support in kodi/mpv, and mainline kernel have not yet settled on what drm properties to use for HDR since there is no userspace implementation that uses them.
(mainline requires a full userspace implementation when adding new drm properties)


Regarding mali we got great support from RK when the gbm version was missing an extension that was enabled in wayland version, an RK engineer was able to change some mali ddk code and provide us with https://github.com/rockchip-linux/libmal...94a0700d74 to solve our issue.
I suggest you open an issue on RK libmali repo with good and simple code that can reproduce the issue and hope for the best.
