I have one on a shelf and want to use it for h265->h264 transcoding. http://www.orangepi.org/html/hardWare/computerAndMicrocontrollers/details/Orange-Pi-One-Plus.html says it can.
H6 Quad-core 64-bit ARM Cortex™-A53
Decoding: H265/HEVC Main/Main10 profile@Level5.2 High-tier ;4K@60fps, up to 6Kx4K@30fps
Encoding: H.264 BP/MP/HP encoder up to 4K@25fps or 1080p@60fps
Googling finds some old branches of ffmpeg and kernel for H3.
Current armbian 25.2.3 comes with 6.12.20-current-sunxi64 which has:
sunxi_cedrus
v4l2_mem2mem
videobuf2_dma_contig
videobuf2_v4l2
videodev
videobuf2_common
mc
so the kernel seems to be aware of my specific chip (hence sunxi_cedrus) and modern Kodi seems to support decoding but nothing about encoding.
Is that it, encoding is just not supported and my Pi is only good as a player?
ps. sadly there is no One Plus specific forum and no common Sunxi forum and for some reason I must choose one of the boards and hence Quadra which seems using H6.
