  • libFLAC : Put upper bound on number of seek points.

    18 février 2015, par Erik de Castro Lopo
    libFLAC : Put upper bound on number of seek points.

    Restrict number of seek points to 32768 total and a maximum of two per
    
second.
    

    Ten hours of content is 36000 seconds which gives about one seek point
    
for every second for those ten hours. Also, having more than two seek
    
point per second makes little sense regardless of content length.
    

    Without these restrictions flac-to-flac encoding of a malformed input
    
file (eg something generated with http://lcamtuf.coredump.cx/afl/)
    
can result in an attempt to generate a stupidly large number of seek
    
points and cause an allocation failure.

  • Compile FFmpeg Zeranoe Build with Visual Studio 2013

    29 août 2017, par mFeinstein

    I downloaded the most recent Zeranoe dev build here, included the header files to my code, placed extern "C" around the includes, since this is a C++ project and FFmpeg is a C library, and added the libs to Visual Studio as well, and I get this linker error :

    1>M :\Desktop\OpenCVTest\Debug\OpenCVTest.exe : fatal error LNK1120 : 14 unresolved externals

    Searching here and on Google I found many recommendations, such as to add #pragma comment(lib,...), and that the libs are static, so their order is important, and none of this helps.

    So I scratched my head even more and realized that the Zeranoe build is made with MinGW-w64, so probably it won’t link with Visual Studio. I inspected the lib using dumpbin and the symbols on the libs don’t have the underscore, so I am pretty sure it won’t work.

    The other Zeranoe builds for Windows don’t have libs, they are just plain .exe or exe + .dll.

    Will I have to make my own VS2013 build of FFmpeg to link it, or is there some alternative way ?
