I need a way to extract the audio from some video (in PHP). I have the video streaming in from YouTube, so I would really like it if it were on the fly streaming, not I have to save it to a temp directory and process it there (though that is acceptable.) Thanks, Isaac Waller
Edit: to be more specific, I have a MP4 and I want it to be a MP3.
You’re going to want to use something like ffmpeg and call it using php’s exec command. If you look around in the docs, I’m sure you can figure out what flag to use to only get the audio.
I’ve used this app before on a project for live transcoding of video, works like a charm. Just make sure your server has it correctly installed.
