pfsinyuv(1)		    General Commands Manual		   pfsinyuv(1)

NAME
       pfsinyuv	 -  Read  frames  from	a  single .yuv file used by many video
       codecs

SYNOPSIS
       pfsinyuv	 [--verbose]  [--quiet]	 [--width]  [--height]	[--colorspace]
       [--noguess]  [--chroma-subsampling]  [--bit-depth]  [--frames] [--help]
       <file>

DESCRIPTION
       Use this	command	to read	an uncompressed	yuv file into a	pfsstream.

       <file> may contain one or more formatting strings, which	 describe  the
       format of the yuv file. The formating strings are:

       %s     The entire description in	the format <width>x<height>_<fps><bit-
	      depth>_<colorspace>_<chroma-format>,	   for	       example
	      1920x1080_25_10b_pq2020_420

       %d     Width in pixels

       %d     Height in	pixels

       %d     Bit-depth	in bits

       %s     Colorspace, such as 'bt709'

       %s     Chroma subsampling format, either	'444' or '420'

OPTIONS
       --width,	-w
	      Specify the width	in pixels of the YUV file

       --height, -h
	      Specify the height in pixels of the YUV file

       --fps, -f
	      Specify the frames per second of the YUV file

       --bit-depth, -b
	      Bit-depth	of the integer values stored in	the yuv	file. A	single
	      color component is stored	as a byte if bit-depth is 8, or	as two
	      bytes otherwise. Default:	10 [bits]

       --chroma-format,	-s
	      Specify the chroma format	of the YUV file. Can be	one of:

	      444 Standard 4:4:4 YCbCr format, with no chroma downsampling]

	      420 4:2:0	YCbCr format, with both	colour channels	downsampled by
	      half

       --colorspace, -c	Currently it can be either:

	      pq2020 for HDR images with BT.2020 colorspace  and  PQ  transfer
	      function,	or

	      bt709  for LDR images in BT.709 (rec.709)	colorspace without any
	      transfer function	or

	      hlg2020 for HDR images with BT.2020 colorspace and HLG  transfer
	      function.

       If  no  option is specified, colorspace is inferred from	the LUMINANNCE
       tag in the pfsstream: pq2020 if	LUMINANCE  is  ABSOLUTE	 or  RELATIVE,
       bt709 if	LUMINANCE is DISPLAY.

       --no-guess, -n
	      Don't try	to extract image metadata from the filename

       --frames, -r
	      Read  only  frames  within the range specified as	first:last, or
	      first:step:last. The frames are indexed from 1, so that  the  to
	      read the first and second	frame one needs	to specify 1:2.

       --verbose, -v
	      Print extra information to stderr.

       --quiet,	-q
	      Disable  warning	message	 about the change in handling absolute
	      values in	RGBE files. See	IMPORTANT NOTE below.
