How I can convert this data to LPCM?
Isn't _that_ called LPCM?
My hardware decoder in the embedded device can play sound in the
LpcmDvd, LpcmHdDvd or LpcmBluRay formats.
I have found function "pcm_bluray_parse_header" in file "pcm-mpeg.c"
Comment on this function is "Parse the header of a LPCM frame read
from a MPEG-TS stream"
So, I think, that LPCM must have some specific header...
I found LPCM header format, but I'm not sure, that it is correct:
http://lists.mplayerhq.hu/pipermail/mplayer-dvb/2001-December/000224.html
id 8 bit
number of frames 8 bit
first acces unit pointer, i.e. start of audio frame 16 bit
audio emphasis on-off 1 bit
audio mute on-off 1 bit
reserved 1 bit
audio frame number 5 bit
quantization word length 2 bit
audio sampling frequency (48khz = 0, 96khz = 1) 2 bit
reserved 1 bit
number of audio channels - 1 (e.g. stereo = 1) 3 bit
dynamic range control (0x80 if off) 8 bit
