Yeah, ffmpeg is a pretty successful open source project to now give credit to just one man. I remember the times when AviDemux had a much faster / better H.264 encoder implementation than ffmpeg. Open source being open source, ffmpeg incorporated AviDemux code into it and ultimately even AviDemux pragmatically opted to use ffmpeg as its backend instead of trying to compete with it. (Best example of embracing the open source spirit).
