#OpenRTSP的使用

保存文件

列举一般使用的的几个命令

-d [time]--------这个是录制时间，就是单位秒，超时后，程序自动结束。

-i -----------以.avi文件格式生成。

-4-------------以.mp4文件格式生成。

-q---------是以.mov文件格式生成。

全部的命令介绍在这里

命令示例:

以mp4格式为例:

openRTSP -4 -d 15 rtsp://192.168.123.244:8554/mtvh.264 >~/Documents/tmp/a.mp4 

保存H264裸流

从这里找到的命令

示例：

openRTSP -d 20 -f 3 -w 640 -h 480 -b 400000 rtsp://192.168.123.244:8554/mtvh.264

运行之后，控制台会出现这样

这行命令会在本目录下生成h264文件，使用Subline Text查看即可知道文件流。

左边是OpenRTSP保存的，右边是原始流。

这里说VLC客户端不能播放，OpenRTSP导出的缺少一些sps以及pps信息，导致VLC无法播放。自己测试，使用本地文件方式确实无法播放，放在live555MediaServer目录下，作为一个服务是可以播放的，应该在客户端做了兼容。照着修改了playCommon.cpp表现一样，还需继续研究。

这里指定了输出路径生成的文件是0字节的，不指定默认在当前目录生成一个video-H264-1文件是正确的h264裸流文件。

Demo

用Mac程序做了个命令行Demo,可以使用。做成iOS存储路径需要修改

#import <Foundation/Foundation.h>
#import "playCommon.hh"

int main(int argc, const char * argv[]) {
    @autoreleasepool {
        // insert code here...
        NSLog(@"Hello, World!");
        //openRTSP(argc,argv);
        char *p[] = {"openRTSP","-d","20","rtsp://192.168.123.244:8554/mtvh.264"};
        openRTSP(4, p);
    }
    return 0;
}
