I don't think so. The RV series uses a special version of MPP, which might be incompatible with this. I have no experience using those chips; you'll need to try it yourself.

It runs very well on the rv1126 device (since testing these days). My device is ARMv7, so I need to compile MPP, RGA, and FFmpeg for ARMv7. The code used is all from the Compilation section in this wiki.

My test:
./ffmpeg -c:v h264_rkmpp -i " rtsp://192.168.1.79:554/stream1&channel=1 " -c:v h264_rkmpp -rc_mode 0 -qp_init 30 -qp_min 30 -qp_min_i 25 -f rtsp rtsp://0.0.0.0:9554/mystream

That's great. My concern was about the memory allocator MPP used on RV series.
