 I updated the ffmpeg port to have alac encoding support in m4a files, I
 dropped the default variants as liba52 is not supported anymore by
 configure script, ffmpeg has its own library now.
 Fixing this ticket could probably close #17310 too.

 I didn't crete patchfile, just change revision to 13, the svn revision
 variables to
 {{{
 set svn_rev 15943
 set swscale_svn_rev 27970
 }}}
 and the libwscale in fetch phase to
 {{{
 system "svn co -r${swscale_svn_rev}
 svn://svn.mplayerhq.hu/mplayer/trunk/libswscale
 ${distpath}/${svn_rev}/trunk/libswscale"
 }}}
