ffmpeg notes

I often want to do something that I believe is non-trivial in ffmpeg, only to discover that it is actually very simple, if only I had known how to do it. I even end up writing wrappers to do simple things, because I keep forgetting what to do. However, this file is my new solution: simply write my own documentation for things I would occasionally like to do.
