FLV to SWF Using FFMPEG command line

FFmpeg, is probably one of the most versatile converters around, and used in many projects across platforms.

In Ubuntu, For a quick and dirty way to convert FLV files to SWF files I use:

ffmpeg -i input.flv -acodec copy -vcodec copy output.swf

There is also a GUI-version available (cross-platform) @ http://code.google.com/p/winff/
