@Mosu,
LPCM streams in VOB files are marked with "stream_index & 0xf0 == 0xa0". Each PES LPCM data block has a 3 byte header. Here's how to read the header:
Code:
channels = buf[1] & 0x7 + 1;
bitdepth = (buf[1] & 0xc0) >> 6; // 0=16bit; 1=20bit; 2=24bit
samplerate = (buf[1] & 0x30) >> 4; // 0=48k; 1=96k; 2=192k
The actual LPCM data for 16bit tracks is stored as expected (in big endian). However, 20bit/24bit is stored rather strangely. Unfortunately I don't have any samples for 20bit and 24bit...
Please note that the header is different for EVO files!
