• Dash.js not playing mpd files made with ffmpeg

  31 décembre 2022, par Macster

  I'm using ffmpeg to create chunks and manifest of a webm file which I want to live stream with Dash.js. Unfortunately Dash.js won't play the mpd file, no matter which way I create the chunks and manifest. However, the sample mpd URL from Dash.js is working.

I tried to delete the ContetntComponent like suggested in other questions, but it didn't work.

  UPDATE

  


  Well, it seems like the problem in general was, that the mpd's wouldn't play from that /dash folder. So i took a look into the code and found a bad routing. Anyways, the mpd would't start with the given command I used, probably becasue it creates a dynamic manifest, like @Markus Schumann says. So I'm going with a new one which seems to be working for now, but not very well.

• ffmpeg conversion from Flac to Ogg produces corrupted files

  8 avril 2021, par experimental

  i transcoded flac files to ogg using this command

  


  ffmpeg -i input.flac -c:a libvorbis -b:a 500k  output.ogg


  


  yes i use 500k to keep the highest quality possible, some of the files are ok, but some of them can not be played - Unsupported format or corrupted file says the foobar - also my icecast streamer cant read it. So there is something wrong with the files.

  


  I believed it was due to the high bitrate so I tried

  


  ffmpeg -i input.flac -c:a libvorbis -b:a 320k  output.ogg


  


  the same happened, some files were ok, some were not playable.
so I tried again with default using this command

  


  ffmpeg -i input.flac -c:a libvorbis output.ogg


  


  same thing. some files were ok, some were corrupted and not playable.

  


  i have no clue why.

  


  both flac and ogg are in the same family, what happened during the transcoding that it became a corrupted file ?

  


  the spectral analysis does not show anything wrong - here it the ogg https://prnt.sc/115zdjl, here is the original flac https://prnt.sc/115zegw

  


  i am really interested what is going on and how to make it work ?

  


  can anyone explain ?

  


  here is complete log

• Flutter FFMPEG : Error setting profile baseline

  9 avril 2021, par Raj Dhakad

  Flutter-ffmpeg unable to set profile parameter. (I need to use profile so the rendered video can be played on WhatsApp).

  


  I am converting.bmp images into a mp4 video. Other I have tested other praramets and the work great it's only -profile:v which seems to have some problem.

  


  Everything works fine unless I use -profile:v baseline.

  


  void _runFFmpeg() async {
    var dir = await getApplicationDocumentsDirectory();
    var output = await getExternalStorageDirectory();
    String videoSize = '${ImageWidth}x$ImageSize';
    print("${ImageWidth}x$ImageSize");
    var arguments = [
      "-y", // replace output file if it already exists
      "-framerate", "30", // framrate
      "-video_size", videoSize,
      "-pixel_format", "yuv420p",
      "-i", "${output.path}/frame_%d.bmp",  
      "-profile:v", "baseline",
      "-level", "3.0",
      "${output.path}/test.mp4"
    ];
    
    _flutterFFmpeg
        .executeWithArguments(arguments)
        .then((rc) => print("FFmpeg process exited with rc $rc"));
 

    print("Done Rendering");
  }
