...ute() function eg. seek_absolute(3561525); and step inside it with gdb, then print the value of "sample" (the arguement), it is NOT 3561525, rather it is some huge number like 4621539102901141517. I figure it could be something to do with types or something, seek_absolute expects a FLAC__uint64, I have tried a few things along this line without success eg. FLAC__uint64 seekpos = 3561525; seek_absolute(seekpos); doesn't work either. Does anyone know what this problem is, or has anyone else had problem with seek_absolute of the C++ File decoder class ?? Thanks, Dave

...change. Declarations from MSDN: unsigned char _BitScanReverse(unsigned long * Index, unsigned long Mask); unsigned char _BitScanReverse64(unsigned long * Index, unsigned __int64 Mask); FLAC uses them as: _BitScanReverse(FLAC__uint32* idx, FLAC__uint32 v); and _BitScanReverse64(FLAC__uint64* idx, FLAC__uint64 v); AFAIK unsigned long is not the same type as FLAC__uint32 (= unsigned int) but it doesn't really matter since both of them are 4-byte unsigned integers. However, _BitScanReverse64 expects a pointer to a 4-byte uint, but it is called with a pointer to a 8-byte uint. The g...

In the precompute_partition_info_sums_ function, instead of selecting 64-bit accumulator when the signal bps is larger than 16, revert to the original approach based on partition size, but make room for few extra bits to not overflow with unusual signals where the average residual magnitude may be larger than bps. It slightly improves the performance with standard encoding levels and 16-bit files
