xcamera_record.cpp

cpp 复制代码

#include "xcamera_record.h"
#include "xdemux_task.h"
#include "xmux_task.h"

void XCameraRecord::Main()//124
{
    XDemuxTask demux;
    XMuxTask mux;
    if (rtsp_url_.empty())
    {
        LOGERROR("open rtsp url failed!");
        return;
    }

    //自定重连
    while (!is_exit_)
    {
        if (demux.Open(rtsp_url_)) //最坏情况阻塞1秒
        {
            break;
        }
        MSleep(10);
        continue;
    }
    //音视频参数
    auto vpara = demux.CopyVideoPara();
    if (!vpara)
    {
        LOGERROR("demux.CopyVideoPara failed!");
        //需要考虑demux 资源释放的问题
        demux.Stop();
        return;
    }
    //启动解封装线程，提前启动，防止超时
    demux.Start();

    auto apara = demux.CopyAudioPara();

    AVCodecParameters* para = nullptr;  //音频参数
    AVRational* timebase = nullptr;     //音频时间基数
    if (apara)
    {
        para = apara->para;
        timebase = apara->time_base;
    }

    if (!mux.Open(save_path_.c_str(),
        vpara->para, vpara->time_base,//视频参数
        para, timebase))            //音频参数
    {
        LOGERROR("mux.Open rtsp_url_ failed!");
        demux.Stop();
        mux.Stop();
        return;
    }
    demux.set_next(&mux);
    mux.Start();
    MSleep(3000);
    mux.Stop();
    demux.Stop();
}

主函数:

cpp 复制代码

int main(int argc, char *argv[])
{
    XCameraRecord xr;
    xr.set_rtsp_url(
        "v1080.mp4");
    xr.set_save_path("./testrecord.mp4");
    xr.Start();
}

运行结果:

录制了两个视频在当前目录下
