gstreamer plug-in development-Constructing the Boilerplate

Constructing the Boilerplate Construction template file In this chapter, you’ll learn how to build minimal code for a new plugin. Starting from scratch, you will see how to obtain the GStreamer template source. You’ll then learn how to use some basic tools to copy and modify template plugins to create new plugins. If you follow […]

Gstreamer implements preview and dynamic recording

The goal is to be able to enter the recording command in the command line during preview to record. The code is as follows: #include <gst/gst.h> #include <stdio.h> #include <linux/input.h> #include <sys/types.h> #include <sys/stat.h> #include <fcntl.h> #include <stdlib.h> static gboolean bus_call (GstBus * bus, GstMessage * msg, gpointer data) { GMainLoop *loop = (GMainLoop *) […]

Gstreamer – local UDP port receives H264 data and decodes (mppvideodec) to YUV

The following code usage scenarios: It is used for other processes in the current RK device to forward the video data to the local port after receiving the video data. The current process reads the video data from the local port, decodes it into YUV through the hard decoder mppvideodec, and converts YUV into RGB […]

RockChip3568 MPP hard decoding and gstreamer1.0 compilation

MPP video hardware decoding and compiling 1. Configure the rock sdk environment The currently used rk3568 sdk package provided by rockchip has an unknown version and should be relatively new. Configure the environment before compiling: source envsetup.sh Select rk3568 configuration (67 rockchip_rk3568) Note: Every time you compile make in the skd directory, you must run […]
