Hi, as described in the ffmpeg documentation http://ffmpeg.org/platform.html#Windows under 4.2, I have set up MinGW/MSys to compile using the MSVC toolchain and c99-to-c89 tool. I have got that to build, however compared to builds from the zeranoe site (and also builds I have asked a friend of mine to make for me using mingw with gcc), I always end up with seeking problems.
In most files everything seems to work fine, however when I have larger MKV files (for example I got one 15 GB movie file), the seeking can take several minutes (depending how far into the file I seek). The same code works fine however when I used one of the zeranoe builds (ie seeking near instant in the same file) The main difference seems to be that I use the msvc toolchain. I used this configuration (which contains the essentails I need: LGPL, v3, dxva2 support, shared dlls): --toolchain=msvc --enable-hwaccels --enable-dxva2 --disable-debug --enable-shared --disable-static --enable-version3 Before that I have also tried this: --toolchain=msvc --arch=x86_32 --target-os=win32 --enable-memalign-hack --disable-static --enable-shared --enable-runtime-cpudetect --disable-encoders --disable-muxers --enable-hwaccels --disable-w32threads --enable-version3 --enable-dxva2 --enable-hwaccel=h264_dxva2 --disable-debug" (and also some variations between the above two.. never with any luck) Has anyone experienced similar problems? Or any hint on how I can resolve that problem?
