Just to make sure:
Container formats are of course also patented.

Just to make sure I understand correctly:
The following works fine:
$ make distclean
$ ./configure --toolchain=msvc --enable-shared
$ make ffmpeg.exe

The following fails with an error when linking 
libswresample:
$ make distclean
$ ./configure --toolchain=msvc --enable-shared --disable-encoders
$ make ffmpeg.exe

And the same for this configure line:
$ make distclean
$ ./configure --toolchain=msvc --enable-shared --disable-deoders
$ make ffmpeg.exe

This is very difficult to understand...
