Kacper Michajłow 047eb18451 avcodec: add PCM DVD-Audio decoder ...

Decodes the LPCM variant found in DVD-Audio AOB streams. Unlike
DVD-Video LPCM it supports up to 192 kHz sample rates and splits
channels in two channel groups, which may use different quantization.
Samples are grouped in sets of 2 samples over all channels, with the
second channel group's data stored first within each set, as 16-bit
big-endian most significant parts followed by the remaining bits.

Based on information from expired US 6,580,671 patent et al.
