NAME

6       pfsinyuv  -  Read  frames  from  a  single .yuv file used by many video
7       codecs
8

SYNOPSIS

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

DESCRIPTION

16       Use this command to read an uncompressed yuv file into a pfsstream.
17
18       <file> may contain one or more formatting strings, which  describe  the
19       format of the yuv file. The formatting strings are:
20
21       %s     The entire description in the format <width>x<height>_<fps><bit‐
22              depth>_<colorspace>_<chroma-format>,         for         example
23              1920x1080_25_10b_pq2020_420
24
25       %d     Width in pixels
26
27       %d     Height in pixels
28
29       %d     Bit-depth in bits
30
31       %s     Colorspace, such as 'bt709'
32
33       %s     Chroma subsampling format, either '444' or '420'
34

OPTIONS

36       --width, -w
37              Specify the width in pixels of the YUV file
38
39       --height, -h
40              Specify the height in pixels of the YUV file
41
42       --fps, -f
43              Specify the frames per second of the YUV file
44
45       --bit-depth, -b
46              Bit-depth of the integer values stored in the yuv file. A single
47              color component is stored as a byte if bit-depth is 8, or as two
48              bytes otherwise. Default: 10 [bits]
49
50       --chroma-format, -s
51              Specify the chroma format of the YUV file. Can be one of:
52
53              444 Standard 4:4:4 YCbCr format, with no chroma downsampling
54
55              420 4:2:0 YCbCr format, with both colour channels downsampled by
56              half
57
58              V210 The v210 format is a packed YUV 4:2:2 (UYVY) format with 10
59              bits per component
60
61       --colorspace, -c Currently it can be either:
62
63              pq2020  for  HDR  images with BT.2020 colorspace and PQ transfer
64              function, or
65
66              bt709 for LDR images in BT.709 (rec.709) colorspace without  any
67              transfer function or
68
69              hlg2020  for HDR images with BT.2020 colorspace and HLG transfer
70              function.
71
72       If no option is specified, colorspace is inferred from  the  LUMINANNCE
73       tag  in  the  pfsstream:  pq2020  if LUMINANCE is ABSOLUTE or RELATIVE,
74       bt709 if LUMINANCE is DISPLAY.
75
76       --no-guess, -n
77              Don't try to extract image metadata from the filename
78
79       --frames, -r
80              Read only frames within the range specified  as  first:last,  or
81              first:step:last.  The  frames are indexed from 1, so that the to
82              read the first and second frame one needs to specify 1:2.
83
84       --verbose, -v
85              Print extra information to stderr.
86
87       --quiet, -q
88              Disable warning message about the change  in  handling  absolute
89              values in RGBE files. See IMPORTANT NOTE below.
