Hello,
I am quite new to this topic, and I have found it to be quite complex. I primarily work with tiny MCUs and RTOSes, but I am enjoying the Linux space so far.
In essence I would like to use the Mali GPU that is embedded within the RK3399 of the Helios64 for hardware transcoding. This isn't a novel idea, as shown by these sources:
https://forum.armbian.com/topic/9272-development-rk3399-media-script/
https://emby.media/community/index.php?/topic/66675-36078-transcoding-rockpro64/
I am using Jellying, and in so FFMPEG to decode/encode the data streams. It seems that V4L2 is supported for hardware ecoding/decoding in the FFMPEG package, but in my experience doesn't appropriately work with the Mesa Panfrost drivers (https://wiki.debian.org/PanfrostLima) and the ARM drivers fail to compile with the kernel headers provided by the armbian-config script. I like the idea of having hardware accelerated transcoding, and I'm not even interested in 4K content, but my helios64 fails to transcode h265 (HEVC) to h264 at a playable rate. Secondly I like to have watch-togethers with my friends and I have to use my power-hungry PC for this. Of course I can introduce new hardware to do this like an arm64 laptop, but I like the all-in-one solution, and I simply can't be the only one that feels this way.
Has anyone had success with hardware acceleration? Any ROE or ongoing efforts?
Thanks,
Victor
