Only the JPEG encoder is available for now, although there are patches for the undocumented VP8 encoder floating around[0].
This has been tested on a rock-5b, resulting in four /dev/video* encoders. The userspace program I’ve been using to test them is Onix[1], using the jpeg-encoder example, it will pick one of these four at random (but displays the one it picked): % ffmpeg -i <input image> -pix_fmt yuvj420p temp.yuv % jpeg-encoder temp.yuv <width> <height> NV12 <quality> output.jpeg

Changes since v1: - Dropped patches 1 and 4. - Use the proper compatible form, since this device should be fully compatible with the VEPU of rk356x. - Describe where the VEPU121 name comes from, and list other encoders and decoders present in this SoC. - Properly test the device tree changes, I previously couldn’t since I was using a too recent version of python-jsonschema…
