Xuggle 5.5 (64bit) - SandyBridge/IvyBridge compatibility test

[Itaru]

hyakki, if it's not too much trouble, can you make a build of Xuggle 5.5 with AVX enabled for me to test? I just want to confirm whether it was indeed buggy AVX support which caused the instability problem. It's still possible that the instability bug is not due to AVX support in ffmpeg but due to a bug in 5.4 that got fixed in the latest GIT source. Even if it was due to buggy AVX support, perhaps that's what got fixed in the latest GIT source, in which case there shouldn't be any need to disable AVX.
