 I verified the problem is compiler specific testing it in gcc.

 The attacched (test.tar.bz2) c++ sample works in gcc with SSE extensions
 enabled. With MSVC++ --> crash. It just need a (possibly interlaced) video
 to be set in the
 Test.cpp source.

 Follows compile instructions:

 Reflect include/ and /lib dirs to the correct headers and
 shared objects locations of ffmpeg

 g++ -c -o libav.o -Iinclude/ -D__STDC_CONSTANT_MACROS libav.cpp
 g++ -c -o Test.o -Iinclude/ -D__STDC_CONSTANT_MACROS Test.cpp
 g++ -o Test libav.o -Llib/ -llibavformat -llibavcodec -llibavdevice
 -llibavutil -llibavfilter -llibswscale Test.o
