Hi, I'm trying to use both libraries in the same project, but sonymvd4.dll seems to interfere with mxflib. My application crashes when it calls MXFFile::Open() which calls ReadRunIn() which calls Seek(0). If I don't instantiate the TFileAccess class or I include the mxflib.h in a .cpp file instead of a .h file, then everything works fine. Does anyone know anything about an incompatibility between these two libraries? Thanks, Paul

This is a very interesting error. This could possibly be due to an incompatibility between the different file-io systems available. By default MXFLib uses low-level I/O rather than the more normal stream I/O when compiled with Visual Studio. This is because it has support for > 4GByte files in earlier versions of the compiler. Try adding the following section to system.h (roughly line 234) in place of the normal versions: Code: #ifndef MXFLIB_NO_FILE_IO typedef FILE FileHandle; inline int FileSeek(FileHandle file, UInt64 offset) { return _fseeki64(file, offset, SEEK_SET); } inline int FileSeekEnd(FileHandle file) { return _fseeki64(file, 0, SEEK_END); } inline size_t FileRead(FileHandle file, unsigned char dest, size_t size) { return fread(dest, 1, size, file); } inline size_t FileWrite(FileHandle file, const unsigned char source, size_t size) { return fwrite(source, 1, size, file); } inline int FileGetc(FileHandle file) { UInt8 c; return (FileRead(file, &c, 1) == 1) ? (int)c : EOF; } inline FileHandle FileOpen(const char filename) { return fopen(filename, "r+b" ); } inline FileHandle FileOpenRead(const char filename) { return fopen(filename, "rb" ); } inline FileHandle FileOpenNew(const char filename) { return fopen(filename, "w+b"); } inline bool FileValid(FileHandle file) { return (file != NULL); } inline bool FileEof(FileHandle file) { return feof(file) ? true : false; } inline UInt64 FileTell(FileHandle file) { return _ftelli64(file); } inline void FileClose(FileHandle file) { fclose(file); } inline bool FileExists(const char *filename) { struct stat buf; return stat(filename, &buf) == 0; } #endif //MXFLIB_NO_FILE_IO
