There was something that applications used, and that worked
documentation could have been better and there was no
real delineation between internal and external API IIRC

These things incrementally improved as problems where hit

whatever API we would design/choose to be used for plugins should
be "well designed" (that is it should strive for simplicity,
completeness, correctness, long term stability, efficiency, ...)

and i belive if we create such an API, all internal codecs, (de)muxers,
filters, protocols and so on should also be moved to use it.
