FFmpeg Cheat Sheet

A little FFmpeg 0.5 guide made by RodrigoPolo.com

This is a small personal cheat sheet for audio/video encoding where I put some of my most used stuff with FFmpeg 0.5 and other tools. I use H.264 and AAC on MP4, M4V or MKV container most of the time.

I also have a FFmpeg command generator tool here, If you have any question just contact me, if you want to help, give us a donation:
