FFmpeg file conversion formats and file extensions

I hope someone knows a link to point me to here.

I'm converting different video and audio formats using ffmpeg. I want to only let files with file extensions be converted that are supported by ffmpeg. The supported formats are found here: http://ffmpeg.org/general.html#SEC4

My question: is there a list of file extensions somewhere? I don't want to research for every format which file extensions might be used for that. Or is there a pain-free format-recognition library or class for C#/.NET available, that can scan for a audio/video format?

Solution

  • If you call ffmpeg with just the input file and no other parameters, it will give you information on the contained streams, if it can read them.

    ffmpeg -i input.avi
