bug: HasFixedBlockSize #8
Description
HasFixedBlockSize field has inverted state.
from https://xiph.org/flac/format.html#frame_header
0 : fixed-blocksize stream; frame header encodes the frame number
1 : variable-blocksize stream; frame header encodes the sample number
but in code:
// 1 bit: HasFixedBlockSize.
x, err = br.Read(1)
if err != nil {
return unexpected(err)
}
if x != 0 {
frame.HasFixedBlockSize = true
}
