[Ffmpeg-devel] [PATCH] Build failes on i386 if snow is disabled

[Martin Storsjö]

Hi,

When building shared libraries of ffmpeg on OS X on i386 with the snow 
encoder and decoder disabled, the build fails due to an undefined 
reference to ff_snow_inner_add_yblock in i386/snowdsp_mmx.o. The attached 
patch fixes this, by only including that object file when building the 
snow encoder.

Kind regards,
// Martin Storsj?
