Using the HW encoder with ffmpeg

[cmuki]

Dear developer,

Are you aware of a way to use the encoder for transcoding with ffmpeg? I would like to use it with Jellyfin to transcode videos.
I searched a lot of projects and built a kernel with the Cedrus VPU Driver (and other modules), but couldn't find a way to do it, especially with a modern kernel (there are several github repos, but a lot of them are over 5 years old and not updated).
For reference here - a lot of work was done to Rockchip's hwaccel support in Jellyfin and it will be enabled in the 10.9 release.

Best regards,
cmuki
