First of all, you asked to get LPCM _data_.

From this, i assume that LPCM is not a container format, but raw data
format. That is exactly what i described above, and what you get after
avcodec_decode_audio().
Now you talk about your hardware decoder... Maybe you should better
ask straightly what your mission is, like "transcode a movie for
playback on dvd-player "CORPORATION MODEL100500".
My h/w decoder is running on the MIPS chipset Broadcom 7213. I think
you don't know anything about this chipset.
LPCM header for MPEG2 PES info: http://www.mpucoder.com/DVD/ass-hdr.html
I have added LPCM header to the PES header over private stream 1
(http://www.mpucoder.com/DVD/pes-hdr.html).
Now h/w decoder can play decoded by ffmpeg ac3 stereo, but it still
can't play ac3 5.1 sound.
