for audacity urlprotocol is unneeded, ive just changed the code not
to use it and it works fine (see github), its simpler as well.

src/FFmpeg.cpp              |  131 ++++++++++++++-----------------------------

But yes, there are cases (like image2) that need urlprotocol, if
someone wants urlprotocol back a patch is welcome, the ABI situation
with it should be explained in the urlprotocol documentation though so
people dont get bitten by it.
