• Play just audio (without launching a window)

  6 août 2017, par Paradise on E

  Is there a way to hide ffplay window on Windows ? I want to play audio files (some of them have video streem as well), but I don’t want a window to appear. Is there any way to hide window completelly ?

  I took a look at their documentationa and I didn’t find a way to do it. I also searched on the internet and didn’t find anything useful. Everyone are asking "Why in the world do you want to hide window..." and similar questions instead of actually posting an answer on how to do it.

  I believe ffplay doesn’t have native way to hide window. So, what are the most easiest alternative ? One of the alternatives would be to download ffplay source code, modify it and recompile it, but it is definitelly not an easy and quick way.

  Is there any way I can launch a process without showing window. It would be great if there is some way to achieve it when ffplay is launched from Node.js (becuase I am using Node.js’s module child_process to play audio files). So, how can I hide ffplay’s window ?

  My current code is following :

  var cp = require('child_process');
  
  var proc = cp.spawn('ffplay', [
  
    '-no_banner',
  
    '-loglevel', 'panic',
  
    playlist.splice(Math.random() * playlist.length | 0, 1)[0]
  
  ]);

  Question

  How to hide ffplay’s window ? If it is possible using ffplay native arguemnts (which I didn’t find in ther documentation) then what arguments to use ? If there is no native way, then is it possible to do it using Node.js’s module child_process ? If not, is there any other way I can hide ffplay’s window ? Again, I must note that some of files I play have video stream as well. So, is there any way to hide ffplay’s window ?

  Thanks in advance.

• ffmpeg use amix and adelay to play ad over song

  15 mars 2017, par snowkiterdude

  I have two mp3 files, one long and one short(a song and an ad). I need the ad to play over the song starting 15 seconds into the song. I also need the volume of the song to fade out/in slightly before and after the ad. I have tried using amix with adelay but just can’t get it right.

  here is something close but broken.

  ffmpeg -i song.mp3 -i ad.mp3 -filter_complex "amix=inputs=2:duration=first:dropout_transition=2 ;adelay=0|15000" output.mp3

  How can I get the ad to mix with the song properly ?
