Use ffmpeg

Both FriendlyCore and FriendlyDesktop systems are built-in ffmpeg, with bin file, static libraries, and header files, all stored in the /usr/ffmpeg-rkmp directory.
ffmpeg supports the RockChip MPP, for details, please refer to: https://trac.ffmpeg.org/wiki/HWAccelIntro

Test the decoding performance of 4K video:

/usr/ffmpeg-rkmp/bin/ffmpeg -benchmark -loglevel 48 -vcodec h264_rkmpp -i 4K-Chimei-inn-60mbps.mp4 -map 0:v:0 -f null -

The results are shown below:

To play the video, you can use the ffmpeg-based player mpv. The 4K video used for the above test can be found in the test-video directory of the network disk. The network address is http://dl.friendlyarm.com/nanopct4.
