This document mainly introduces how to use hardware decoding on Edge2.
If encounter error, please add sudo and try again.
1. Check decoder.
khadas@Khadas:~$ gst-inspect-1.0 | grep mpp
rockchipmpp: mpph264enc: Rockchip Mpp H264 Encoder
rockchipmpp: mpph265enc: Rockchip Mpp H265 Encoder
rockchipmpp: mppjpegdec: Rockchip's MPP JPEG image decoder
rockchipmpp: mppjpegenc: Rockchip Mpp JPEG Encoder
rockchipmpp: mppvideodec: Rockchip's MPP video decoder
rockchipmpp: mppvp8enc: Rockchip Mpp VP8 Encoder

2. Decoding with H264 file.
khadas@Khadas:~$ gst-launch-1.0 filesrc location=./test.h264 ! h264parse ! mppvideodec ! video/x-raw,format=NV12 ! filesink location=test.yuv

3. Decoding with MP4 file.
khadas@Khadas:~$ gst-launch-1.0 filesrc location=./test.mp4 ! qtdemux name=d d.video_0 ! h264parse ! mppvideodec ! video/x-raw,format=NV12 ! filesink location=test.yuv
