Question

Hey Everyone,
I was wondering if there is a current class or library in a web language (php, perl, etc.) that is able to extract audio from flash files or youtube links directly.

Thanks for your time!

Answer 1

The easiest way to extract audio from a video is to use FFMPEG. There is a PHP extension available, but I have found it easier (due to installation woes) to just call the binary directly with exec().

Here is a great tutorial for stripping the audio from a video file: http://howto-pages.org/ffmpeg/#strip

From that tutorial:

ffmpeg -i mandelbrot.flv -vn -acodec pcm_s16le -ar 44100 -ac 2 mandelbrot.wav

Now if by “flash files” you mean SWF, that is another matter entirely.
