BrainyPi’s SoC Rockchip RK3399 has built-in hardware encoders for H.264/MVC/VP8 and a hardware decoder. But this has only been implemented in GStreamer. This topic is created to consolidate all the information related to it to help with the development of FFmpeg support.

To check if GStreamer plugins are installed on your board run:
gst-inspect-1.0 | grep -i mpp
The output should be something like this:
typefindfunctions: audio/x-musepack: mpc, mpp, mp+
rockchipmpp: mppvideodec: Rockchip's MPP video decoder
rockchipmpp: mpph264enc: Rockchip Mpp H264 Encoder
rockchipmpp: mpph265enc: Rockchip Mpp H265 Encoder
rockchipmpp: mppvp8enc: Rockchip Mpp VP8 Encoder
rockchipmpp: mppjpegenc: Rockchip Mpp JPEG Encoder
rockchipmpp: mppjpegdec: Rockchip's MPP JPEG image decoder
To Decode h264 and again Encode to h264:
gst-launch-1.0 filesrc location=./bbb_sunflower_1080p_60fps_normal.mp4 num-buffers=3000 ! qtdemux name=d d.video_0 ! h264parse ! mppvideodec ! video/x-raw,format=NV12 ! mpph264enc ! h264parse ! qtmux ! filesink location=./h264dec-h264.mp4
To Decode h264 and again Encode to vp8:
gst-launch-1.0 filesrc location=./bbb_sunflower_1080p_60fps_normal.mp4 num-buffers=3000 ! qtdemux name=d d.video_0 ! h264parse ! mppvideodec ! video/x-raw,format=NV12 ! mppvp8enc ! qtmux ! filesink location=./h264dec-vp8.mp4
