You can request H264, MJPG, and raw data from the vidsrc, but only MJPG and raw data from the vfsrc. When requesting H264 from the vidsrc, then the max resolution for the vfsrc will be 640×480, which can be served as jpg or as raw (decoded from jpg). So if you don...
Basically the source is Video 4 Linux Version 2 (v4l2src) using video device 0. Ask the camera for MJPG (image/jpeg) 1920×1080 resolution at a frame rate of 30 frames per second. Gstreamer calls this acapability. Because the video is encoded as MJPG (a compressed image), you have ...
二、代码直接配套携带opencv库,且能够在rk3568终端中使用gstreamer访问mipi摄像头。 1、编译安装支持gstreamer版本的opencv,相关教程自己去网上查询。 这边直接给出一个编译好的opencv库文件地址: 链接:https://pan.baidu.com/s/18-z3SJtgqrviOAuPl0x1xQ 提取码:ncxr 2、代码目录结构如下: opencv_camera -src -...
