  • Downloading, transcoding, then streaming on the fly with VLC

    12 avril 2012, par Alexis K

    I need to download a file from a web service the immediatley extract the audio, then transcode it, then stream it out.

    When I use :

    vlc.exe URL :sout=#transcode{acodec=mp3,ab=128,channels=2,samplerate=44100}:http{dst=:8080/audio.mp3}

    it is really choppy when I listen to it on the other computer. What is strange also is that for some YouTube links, the above works well, but for others it dosen't work well. I am not sure why this is.

    However, when I download the audio first, then stream it out, like this
    vlc.exe "song.mp3" :sout=#transcode{acodec=mp3,ab=128,channels=2,samplerate=44100}:http{dst=:8080/audio.mp3}

    it works well. The issue is I can't always download the song before hand (long pod casts or internet radio...).

    Is there a command or VLC optimization that I can use to help remedy this situation ? Or another program that would be good ?

  • Forwarding rtsp feed from one local port to another

    11 août 2021, par Thabet Sabha

    so let's say I have an rtsp server running on port 554, and when a certain command is received, i want the rtsp server to start forwarding the feed (using rtsp+tcp) to a service running on the same machine but on port 553 (Linux OS), is that possible via a CL command, or do I have to use something like ffmpeg ?

    


    currently this is what is being used, but I feel like this is redundant since all we're doing is just forwarding the feed to another port on the same machine.

    


    const ffmpegOptions = [
"-rtsp_transport", "tcp",
"-i", "rtsp://127.0.0.1:554",
"-codec", "copy",
"-f", "rtsp",
"-rtsp_transport", "tcp",
"rtsp://127.0.0.1:553"
]

const myProcess = spawn('ffmpeg', ffmpegOptions);


    


    Thanks.

    


  • How to manually reset the offset of an mp4 video created from m4s files ?

    12 août 2020, par natdev

    I'm building a service that combine .m4s files (from a dash stream) to a mp4 video.
    
I have some sample m4s files from a random point in time of a stream,
    
using ffmpeg on those file + the init file does the job.

    


    cat init.mp4 032.m4s 033.m4s 034.m4s > output.mp4


    


    I have tried concating the m4s files to the mp4 init file and I manage to play the video,
    
but there is an offset from the encoded video segments.

    


    I guess ffmpeg does reset that somehow, and I was wondering how can I reset that offset as well ?
    
Having a little bit of experience with dash, I know that there is a field name presentationTimeOffset that is responsible to set the offset.
