Hello,
I have rk3399 and installed mpp( https://github.com/rockchip-linux/mpp ).
I am receiving rtsp stream using by ffmpeg(C++).
And now I have to decode h264 video using by mpp but I don't understand how to
do this.
I found https://github.com/FFmpeg/FFmpeg/blob/master/libavcodec/rkmppdec.c

I need an avpacket because i read rtcp stream using by ffmpeg and receive from
the rtcp stream an avpacket. Mpp can't read rtcp stream as i know.
Also I saw that ffmpeg have "--enable-rkmpp" flag at the configuration stage.

I tried to do this, but it doesn't work.(software decoding works, hardware
decoding does not work)

Mpp is built with -DHAVE_DRM.
You are right, my user cannot access the DRM device.
But i started my decoder program with sudo access and this does not
So what is the issue? It seems to be working?

Technically it works, but not completely...
I try do decode 50 packets(i think that each contains 1 frame) and I can't
receive no one decoded frame.
I looked the code of rkmppdec.c. The decoder must print to log " Received a
frame. " but it doesn
