-===== Introduction ===== +{{page>products:sbc:edge2:applications:hardware-encoding&noheader}}
- +
-This document explains how to utilize hardware-accelerated video encoding on the Edge-2L using the Rockchip MPP (Media Process Platform) framework. +
- +
-===== Eencoding ===== +

-</WRAP> +
- +
-1. Verify available MPP encoders +
- +
-First, check that the GStreamer MPP plugins are installed and recognized: +
- +
-```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. Encode a raw YUV (NV12) file to H264 +
- +
-Encode a raw YUV file (test.yuv) in NV12 format to a raw H.264 elementary stream (test.h264). Adjust the width and height parameters to match your source video resolution. +
- +
-```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 PREROLLING ... +
-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. Capture and encode from a USB camera +
- +
-The following examples capture JPEG frames from a USB camera, decode them using the MPP JPEG decoder, and then hardware-encode the video stream to H264. +
- +
-```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 +
-``` +
- +
-You can adapt these pipelines for other encoding formats (e.g., H265, VP8) by simply replacing mpph264enc with the corresponding MPP encoder element (e.g., mpph265enc, mppvp8enc).+
