Hi, I just confirmed that this driver also works for rk356x. I tested it on orangepi3b with kernel 6.9, and chromium can decode 4K H264 video with hardware acceleration. Here is the devicetree patch for rk356x: https://github.com/amazingfate/build/blob/4c3564bc82b8963246450d3ebe1ad93965e7c22f/patch/kernel/archive/rockchip64-6.9/rk356x-add-rkvdec2-support.patch Please ignore the change of vpu's compatiable string change. I did that to disable its 1080p h264 hantro g1 decoder. Best regards, Jianfeng
