-1. Check encoder. +
- +
-```shell +
-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 +
-typefindfunctions: audio/x-musepack: mpc, mpp, mp+ +
- +
-``` +
- +
-2. Encoding format ''NV12'' to ''H264''. +
- +
-```shell +
-khadas@Khadas:~$ gst-launch-1.0 -v filesrc location=./test.yuv ! videoparse width=1920 height=1080 format=nv12 ! mpph264enc ! h264parse ! queue ! filesink location=./test.h264 +
-Setting pipeline to PAUSED ... +

-Pipeline is PREROLLED ... +
-Setting pipeline to PLAYING ... +
-Redistribute latency... +
-New clock: GstSystemClock +
-0:00:16.1 / 0:12:05.0 (2.2 %) +
-^Chandling interrupt. (2.8 %) +
- +
-``` +
- +
-3. Get data from USB camera and encode. +
- +
-<tabbox kernel 5.10.66> +
- +
-```shell +
-khadas@Khadas:~$ gst-launch-1.0 v4l2src device=/dev/video33 io-mode=mmap num-buffers=300 ! image/jpeg, width=1920, height=1080, framerate=30/1 ! mppjpegdec ! mpph264enc ! filesink location=./test.h264 +
-``` +
- +
-<tabbox Other version> +
- +
-```shell +
-khadas@Khadas:~$ gst-launch-1.0 v4l2src device=/dev/video60 io-mode=mmap num-buffers=300 ! image/jpeg, width=1920, height=1080, framerate=30/1 ! mppjpegdec ! mpph264enc ! filesink location=./test.h264 +
-``` +
- +
-</tabbox> +

-Other encoding formats are used similarly. Just replace the corresponding encoder.+
