• 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.
