FLV Audio Extractor

Many programs that download videos from, say, YouTube or Google Video to your computer, often download them in the form of a .FLV file. A lot of times, though, we want to rip the music from that video into MP3 form, etc... so the following program does just that - extracts audio from FLV's into separate files. This is far from a consumer version, first of all it is a command-line tool!

Usage is:
FLV_AudioExtract [input] [output].

For example:
FLV_AudioExtract sample_video.flv sample_video_music.mp3

The audio format may not always be MP3 - be sure to check the "Dominant format: ..." field, it will have something like mono 22 kHz mp3, which is the audio format.

Also included is a tag viewer for FLV files. I'm sure it will be self-explanatory. Big thanks to http://www.osflash.org for reverse engineering the FLV format!
