  • How to set default streams with ffmpeg

    29 décembre 2015, par Sam

    I have some m4v files that I am wanting to add subtitles to with ffmpeg. I know I need to map the streams to get them into the output file but how do I ensure that this subtitle stream will be a default stream ? The subtitles are .srt and people seem to be saying that they are not compatible with mp4 containers, what do I need to convert the subtitles to first ?

    Also, does it matter what order the various streams are in ? Does the video stream always have to come first, followed by the audio, then the subtitles ? Or can you mix them up however you want ? Does it make any difference ?

    Lastly, what is the difference between a default stream and a forced stream ?

  • Why RTP doesn't support multiple streams to one port but RTSP does ?

    30 avril 2022, par zenno2

    I use ffmpeg for streaming a video using RTP protocol.
Why I can't send multiple streams to one RTP port, but RTSP that uses RTP can ?
I started a RTSP server that listens 8554 TCP port and 8000/8001 RTP/RTCP. It easily can receive both video and audio streams to one port 8000, I've checked it with wireshark. But when I try to do the same with pure RTP using ffmpeg, it prints me an error

    


    Only one stream supported in the RTP muxer


    


    And if I want to stream a video with sound, I have to split them into two streams and send to different RTP ports. Or maybe I can somehow make it receive multiple streams to one port via RTP ?

    


    Could you explain me, why it happens ?

    


  • how can I scan live mp3 streams for their sample rate ?

    30 juillet 2012, par Nadal

    I am new to FFMPEG and I am suppose to scan all of my files for sample rate. I am not sure as to what this is because I am new to this and don't know how to even get started with FFMPEG's scanning. These live streams are mp3 streams, music tracks. I am familiar with PHP if that makes any difference.
