[Ffmpeg-devel] [PATCH] AVISynth support

The patch avisynth-input_v4.patch works fine for me, under Cygwin
and MingGW (cross compiled under Cygwin).

Platform is SVN-r6022, Cygwin 1.5.20, gcc 3.4.4, Avisynth 2.56.

Transcode test is:

$ ./ffmpeg -i 'C:\Program Files\AviSynth 2.5\Examples\Authors.avs' -y

1) Static Cygwin
   make distclean; ./configure --enable-static --disable-shared \
   --enable-avisynth; make
   Builds OK.
   Transcodes AVS to PNG OK.

2) Shared Cygwin
   make distclean; ./configure --disable-static --enable-shared \
   --enable-avisynth; make
   Builds OK.
   Transcodes AVS to PNG OK.

3) Static MinGW (cross compiled under Cygwin)
   make distclean; ./configure --enable-mingw32 --enable-memalign-hack \
   --enable-static --disable-shared --enable-avisynth \
   --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin; make
   Builds OK.
   Transcodes AVS to PNG OK.

3) Shared MinGW (cross compiled under Cygwin)
   make distclean; ./configure --enable-mingw32 --enable-memalign-hack \
   --disable-static --enable-shared --enable-avisynth \
   --extra-cflags=-mno-cygwin --extra-libs=-mno-cygwin; make
   Builds OK.
   Transcodes AVS to PNG OK.

make test fails, but exactly in the same steps as if I don't use
--enable-avisynth, so this is an error not related to the patch.

Of course, by now there is already a avisynth-input_v5.patch, I will
re-test it tomorrow ...
