Build errors on Debian Sid ("use of undeclared identifier 'av_register_all' and more)

Hi,

I'm getting the following build errors on Linux / Debian Sid:

$ make

It seems like av_register_all() for instance was deprecated in ffmpeg:

Frmpeg breaks its api quite often. I wont have time to address this for the next months. You can either downgrade to ffmpeg 4 or disable ffmpeg by passing ENABLE_FFMPEG=0 to cmake.

Thanks a lot, using "cmake -DENABLE_FFMPEG=0 .." as a workaround worked and I can play N64 midi/dls files through ANMP now!
