Comment (by acho at macports.org):

 I've looked at this, and a very easy way to "get it working now" is to
 remove the patches from the avfilter variant.  The build system has
 changed significantly from when the patches were made and I haven't yet
 figured out what the ports patches fix (library version mismatching,
 maybe?).

 I've posted some changes I used to get it to build with avfilter.  Apply
 the Portfile diff and drop the patch-libswscale-Makefile.diff in the usual
 place for patches.

 If I find that it won't break anything to remove these patches
 permanently, I'll commit this.
