Hardware transcoding on RK3582 - Vagrantly4 - 2024-08-02
Hello, I'm looking to build a small NAS and the best solution I found so far was using a Radxa Penta SATA Hat with an SBC, something like this. I would like to run my Jellyfin server on the NAS to avoid unnecessary network traffic as my router isn't the most robust and is limited to Gigabit Ethernet. Considering price, availability and compatibility with the hat, an interesting option is the Radxa 5C Lite which uses the RK3582 chip. From what I gathered, this is a budget version of RK3588S and according to the specs on the Radxa website is capable of "H.265 / H.264 multivideo encoder up to 4K@60fps".
Has anyone ever tried to run Jellyfin with HW Acceleration on this chip to see if it behaves well with Rockchip RKMPP?
I usually watch media from Jellyfin on my Samsung 4K HDR10+ TV and try to run it in direct stream, but some codecs don't work well with it and need transcoding, so it would be nice if I could do it directly on the NAS.

@nyanmisaka - Your input would be appreciated.

RK3582 is a down-binning variant of RK3588S. The availability of its GPU (mali-g610), CPU (two of four cortex-a76 cores) and VPU (one of two decoders/encoders) is determined by silicon lottery. Rockchip disabled this uncertainty by default in u-boot bootloader. And there are u-boot patches in the Armbian repo to force them re-enabled and shell scripts on Radxa forum to verify the availability of hardware units.

The CPU has little effect on RKMPP hardware transcoding, and half the VPU will only halve the transcoding speed. But without the GPU you lose HDR to SDR tone-mapping.
