Could be than they're not freely available or license-compatible with 
ffmpeg? (Quite likely, actually.) Or that those codecs are not the best for 
the actual purpose (the output, not the process).

Because for many people it does what's needed ("most important codecs"? like 
mpeg2, h264/265, jpeg, etc).

That's not a "media" format....) And many uses are well-fulfilled by the 
codecs/formats/containers that ffmpeg does support.

misunderstanding of ffmpeg's purpose and license (see
