And then I found http://fobs.sourceforge.net/ (fobs = Ffmpeg objects), which is a c++ wrapper for ffmpeg. I wish I found it much earlier. True, it does not give all the flexibility as ffmpeg itself does, but in return you don't have to become an expert before you are able to use it. I'm posting this as a reference for people like me that just want their video coded decently and don't need to tweak everything. For the more sophisticated coding use libavcodec and such.
