[Ffmpeg-devel] [PATCH] AVISynth support

[Víctor Paesa]

The patch avisynth-input_v5.patch works fine for me, under Cygwin
and MingGW (cross compiled under Cygwin).

Platform is SVN-r6027, Cygwin 1.5.21-2, gcc 3.4.4, binutils 20060817-1,
Avisynth 2.56.

Transcode test is:

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

Scenarios:

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.

4) 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.
