14 NUT is a low overhead generic container format. It stores audio, video,
15 subtitle and user-defined streams in a simple, yet efficient, way.
17 It was created by a group of FFmpeg and MPlayer developers in 2003
18 and was finalized in 2008.
20 The official nut specification is at svn://svn.mplayerhq.hu/nut
21 In case of any differences between this text and the official specification,
22 the official specification shall prevail.

26 @section Generic raw YUVA formats
28 Since many exotic planar YUVA pixel formats are not considered by
29 the AVI/QuickTime FourCC lists, the following scheme is adopted for
32 The first two bytes can contain the values:
38 The third byte represents the width and height chroma subsampling
39 values for the UV planes, that is the amount to shift the luma
40 width/height right to find the chroma width/height.
42 The fourth byte is the number of bits used (8, 16, ...).
44 If the order of bytes is inverted, that means that each component has
45 to be read big-endian.
