Hello, In another attempt at using libav, I have tried to use lib files built from ffmpeg (using msys & mingw). I tried to compile apiexample.c provided in "ffmpeg/libavcodec/" using MSVC 8.0. I am getting following errors:
1>------ Build started: Project: LibSampleApp, Configuration: Debug Win32 ------ 1>Linking... 1>apiexample.obj : error LNK2019: unresolved external symbol _avcodec_decode_audio referenced in function
