Tools like mencoder, On2 Flix Engine, and GStreamer are alternatives, but they share a lot of code with ffmpeg (including the ubiquitous libavcodec). If you want to avoid this altogether, you have a few options, though none of them are as strong as ffmpeg, like Quicktime, Microsoft (Expression Encoder etc.?), and enterprise software or hardware (Rhozet, Inlet, etc.). But I wouldn't be surprised if enterprise appliances even incorporate libavcodec today.
