[Libav-user] Different behaviour when compiling FFmpeg with MingW and VC++2010

Hi everybody,

I tried to compile FFmpeg with 2 different compilers on Windows 7.
After testing both binaries, I don't get the same behaviour. Well, actually with most video files I do get the same results, but with some files I do get different results.

For instance, with the binaries compiled from MingW, I can decode video frames, but with the VC++2010 version I just get an error.
For another video file, after seeking and trying to get a video frame, the MingW version just returns a gray image while the VC++2010 version returns an actual scene from the video.

For the same code base to produce different outputs is quite startling. Does anybody know what the difference can come from?
