[FFmpeg-devel] [PATCH] avformat/nut: add DSDs support

[Takayuki 'January June' Suwa]

codec tags for DSDs are similar to PCMs: 'D'<type><interleaving><bits>, where
 'D' means DSD, or pulse-Density-modulation,
 <type> is 'L' for LSB-first, 'M' for MSB-first
 <interleaving> is 'D' for default, 'P' for planar
 <bits> is always binary one :)
