(Its GPU is too slow for 4K HDR tone mapping anyway). If most of your library is in SDR it could be a good choice if you know how to set that up.
Last time I checked it could do 2160p@55fps with HDR10 tone-mapping enabled. So the RK3588 should be able to handle two 4k@24fps HDR->SDR transcodes.
Regarding DOVI, actually RKMPP parses out the metadata for each frame, but it does not meet the expectations of the DOVI helpers in FFmpeg. It may be related to different data structures or bitstream parsers built into MPP runtime.
