    edrex got a reaction from JMCC in SBC with proper software support for hardware video transcoding   
    Hi @JMCC, I happened upon this thread as I was experimenting with HW encoding for one of my two HC1s, so I was very happy to read your posts and test out your custom ffmpeg build. I'm seeing a modestsubstantial speed boost (1.8x vs 0.9x) compared to the Armbian build.
     
    My encode params are `-vcodec h264_v4l2m2m -num_capture_buffers 32  -pix_fmt nv21`. Any additional suggestions? Thanks
