Mplayer has a quicktime demuxer which reads the properties of the quicktime file (FourCC, height, etc.). It then has a set of codecs that it can use to decode the video. "Codecs.conf" is used to determine which codec to use for each FourCC. If you play a Sorenson Video 3 quicktime with mplayer, the demuxer will determine that the FourCC is SVQ3 and will search through "codecs.conf" for a compatible decoder. The first one listed is ffmpeg, so mplayer will grab compressed media samples from the quicktime file and feed them to the ffmpeg SVQ3 decoder. If you remove or comment out the ffmpeg decoder entry, it will try to use the next one in the list, "Win32/QuickTime SVQ3 decoder." I have not been successful using the quicktime decoders with mplayer but they seem to work with mencoder. I added an entry for Blackmagic's 10Bit codec (v210) and mencoder successfully re-encoded the file to mpeg4.
