1 Description

-

NUT is a low overhead generic container format. It stores audio, video, -subtitle and user-defined streams in a simple, yet efficient, way. -

-

It was created by a group of FFmpeg and MPlayer developers in 2003 -and was finalized in 2008. -

-

The official nut specification is at svn://svn.mplayerhq.hu/nut -In case of any differences between this text and the official specification, -the official specification shall prevail. -

- -

2 Modes

-

NUT has some variants signaled by using the flags field in its main header. -

- - - -
BROADCASTExtend the syncpoint to report the sender wallclock
PIPEOmit completely the syncpoint
- - -

2.1 BROADCAST

- -

The BROADCAST variant provides a secondary time reference to facilitate -detecting endpoint latency and network delays. -It assumes all the endpoint clocks are synchronized. -To be used in real-time scenarios. -

- -

2.2 PIPE

- -

The PIPE variant assumes NUT is used as non-seekable intermediate container, -by not using syncpoint removes unneeded overhead and reduces the overall -memory usage. -

- -

3 Container-specific codec tags

- - -

3.1 Generic raw YUVA formats

- -

Since many exotic planar YUVA pixel formats are not considered by -the AVI/QuickTime FourCC lists, the following scheme is adopted for -representing them. -

-

The first two bytes can contain the values: -Y1 = only Y -Y2 = Y+A -Y3 = YUV -Y4 = YUVA -

-

The third byte represents the width and height chroma subsampling -values for the UV planes, that is the amount to shift the luma -width/height right to find the chroma width/height. -

-

The fourth byte is the number of bits used (8, 16, ...). -

-

If the order of bytes is inverted, that means that each component has -to be read big-endian. -

- -

<type> is S for signed integer, U for unsigned integer, F for IEEE float -<interleaving> is D for default, P is for planar. -<bits> is 8/16/24/32 -

PFD[32]   would for example be signed 32 bit little-endian IEEE float
