why an external library? are you trying to hack existing drm
binaryware (windows dlls??) to decrypt drm content for you? if so this
may be ok. if you mean that you're trying to add your own drm to
mplayer and get around gpl by making it a dynamic-loaded thing, you're
badly mistaken, as this is a flagrant and classic gpl violation.

if you're planning to write your own reverse-engineered drm-decrypting
code for mplayer, under gpl or another free and compatible license,
just include it directly in mplayer. no need for dynamic loading.
