RK3399Pro入门教程（10）RTSP推流介绍

可以在虚拟机上搭建环境吗？

想问下，理论上的延时是多少。
目前，将rtsp接收端重写了下，发现640*480的usb采集的视频，在局域网内推流动，延时都是300ms左右，想提升到150ms，有具体的改进方法么？
或者有没有更高效的推流框架？

你好  我才看到你的问题。
就是将rga例程的“rockchip_rga”文件夹源码放到RTSP例程根目录下，头文件放到 ...

要修改，V4L2.cpp，不是 V4L2.h

[toybrick@localhost IPCamera]$ ./RTSPServer

"h264ESVideoTest" stream, from the file "test.264"
Play this stream using the URL "rtsp://172.23.100.12:8554/h264ESVideoTest"

(We use port 8000 for optional RTSP-over-HTTP tunneling.)

楼主你好，我执行make的时候，找不到相关函数请问如何解决呢？

已解决，谢谢

请教各位大佬，我的是ubuntu系统，更新了源，apt-get install rockchip-rga-dev可以安装rga，但是apt-get install rockchip-mpp-dev却找不到mmp包，有什么办法可以解决吗？

在测试RTSP推流时，VLC端画面只有上半部分显示出来，下半部分变成白色马赛克。其次在示例运行几十秒后出现segment fault:

从gdb调试看，是mmp出现了空指针操作？还麻烦问一下版主，你们几小时测试没有这个问题吗？我是在Debian10下进行的测试。

在linux下用python可以调用吗？有文档吗？
