linux c++ ffmpeg rtsp推流报错 rtsp://localhost:8554/Live: Protocol not found

根据报错内容rtsp://localhost:8554/Live: Protocol not found

意思是没有找到对应协议，添加以下红色字体指令解决，

std::string rtsp_server_url = "rtsp://localhost:8554/live";

std::stringstream command;

command << "ffmpeg ";

command << "-y " // overwrite output files

<< "-an " // disable audio

<< "-f rawvideo " // force format to rawvideo

<< "-vcodec rawvideo " // force video rawvideo ('copy' to copy stream)

<< "-pix_fmt bgr24 " // set pixel format to bgr24

<< "-s 640x516 " // set frame size (WxH or abbreviation)

<< "-r 25 "; // set frame rate (Hz value, fraction or abbreviation)

command << "-i - "; //

command << "-c:v libx264 " // Hyper fast Audio and Video encoder

<< "-pix_fmt yuv420p " // set pixel format to yuv420p

<< "-preset ultrafast " // set the libx264 encoding preset to ultrafast

<< "-f flv " // force format to flv

<< "-rtsp_transport tcp "

<< "-f rtsp "

<< rtsp_server_url;
