FFMPEG - Multimedia Tool

FFmpeg is a free software/open source project that produces libraries and programs for handling multimedia data. It ships with Fedora Linux so I naturally took a dive and have never turned back.....

I normaly use it to convert multimedia files from one format to another. Being a command line tool u expect faster execution.

For example
Convert from MP4 to AVI

#ffmpeg -i inputfile.mp4 outfile.avi

To See Supported File Formats
#ffmpeg -formats

You will get output similar to this
