Hi, I believe this might be related to this problem: http://libav-users.943685.n4.nabble.com/Libav-user-Building-with-MSVC-toolchain-resulting-in-seeking-problem-td4656914.html There was a patch made for that (on March 12th): Commit:713ac21097555722257343494f83999068006653 * avutil/os_support: use 64-bit fstat/lseek variants for MSVC as well http://ffmpeg.org/pipermail/ffmpeg-cvslog/2013-March/061893.html This fix didn't make it into the 1.2 release of ffmpeg though If you need to use 1.2 then maybe you can apply this yourself. regards, Bjoern _______________________________________________ Libav-user mailing list Libav-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/libav-user
