The AMD gpu had SDR (not UHD) capability a long time ago in a FFMPEG 4 version of PMS and was also experimental.
I do not know why Engineering didn’t complete the work.
I do know that with the new FFMPEG 6 version,
- ARC gpus do work with the new ICR and IMD
- AMD gpus are on the To-Do list (short list)
Currently, the Intrastructure team is moving the backend of how PMS is built to a new platform.
When that move is complete, we’ll be able to build PMS again and, IIRC what Chris said, FFMPEG 6 with BattleMage gpus will be mainstream.
AFAIK, after completing the upgrades to all the FFMPEG drivers (there are quite a few), Chris will be adding the AMD suite of drivers which will finally bring AMD into the foreground ( I THINK that’s the plan but don’t know all the details or if I’m 100% accurate )
