8 [-r | |
9 .IR frame-rate ] | |
10 [-w | |

16 .RI [ output-file ] | |
17 .SH DESCRIPTION | |
18 .B blind-from-video | |
19 converts the video, in the file | |
20 .IR input-file , | |
21 to a format usable by the | |
22 .B blind | |
23 tools, and prints the new video to the file | |
24 .IR output-file . | |
25 .I input-file | |
26 and, unless -L is used, | |
27 .I output-file | |
28 must be regular files. | |
29 .I input-file | |
30 must be a normal video file with a container (i.e. not raw video) | |
31 that is supported by | |
32 .BR ffmpeg (1). | |
33 It is unspecified what happens if | |
34 .I input-file | |
35 does not have exactly one video stream. All non-video streams, | |
36 such as audio and subtitles are discarded. | |
37 .P | |
38 If | |
39 .B output-file | |
40 is omitted, | |
41 .RB ' - ' | |
42 (stdout) is used. | |
43 .SH OPTIONS | |
44 .TP | |
45 .B -d | |
46 Perform coarse colour-model conversion. This will increase the | |
47 performance of the conversion, but modifications to the colours | |
48 will not produce the expected colours. This is useful for | |
49 drafting or if you will not modify the colours. If you use this | |
50 flag, you should also use it in | |
51 .BR blind-to-video (1), | |
52 otherwise the colours will be modified. | |
53 .TP | |
54 .BR -F " "\fIpixel-format\fP | |
55 Select pixel format, see | |
56 .BR blind-convert (1) | |
57 for more information. Pixel formats starting with | |
58 .BR raw , | |
59 other than | |
60 .BR raw0 , | |
61 are not supported. | |
62 .TP | |
63 .BR -h " "\fIheight\fP | |
64 Change the height of the video to | |
65 .IR height . | |
66 .TP | |
67 .B -L | |
68 Write to stdout that the number of frames in the video is 0. | |
69 This allows you to use a non-regular file, including a pipe, as | |
70 .IR output-file . | |
71 If you specify | |
72 .RB ' - ' | |
73 as the | |
74 .IR output-file , | |
75 the video is printed to stdout. | |
76 | |
77 This option is useful if you want to split a video, into | |
78 multiple videos, as it allows to to split the video without | |
79 having to store the entire raw video to disc. | |
80 | |
81 If you use this option, you can use | |
82 .BR blind-split (1) | |
83 to write the actual number of frames to the head, if this | |
84 is needed. | |
85 .TP | |
86 .BR -r " "\fIframe-rate\fP | |
87 Change the frame rate of the video to | |
88 .IR frame-rate . | |
89 This value can be a rational. | |
90 .TP | |
91 .BR -w " "\fIwidth\fP | |
92 Change the width of the video to | |
93 .IR width . | |
