2 .SH NAME | |
3 blind-split - Split a video, by frame, into multiple videos | |
4 .SH SYNOPSIS | |
5 .B blind-split | |
6 [-L] | |
7 .RI ( file | |
8 .RI ( end-point | |
9 | | |
10 .RB ' end '))\ ... | |
11 .SH DESCRIPTION | |
12 .B blind-split | |
13 reads a video from stdin and splits into multiple videos. | |
14 Starting from the first frame in stdin, it writes a video | |
15 to the first specified | |
16 .I file | |
17 until the first specified | |
18 .I end-point | |
19 number of frames have been written. | |
20 .B blind-split | |
21 then proceeds to write the following frames to the next | |
22 specified | |
23 .B file | |
24 until a total of | |
25 .I end-point | |
26 frames has been written (that is, including all previous | |
27 videos), where | |
28 .I end-point | |
29 is the associated | |
30 .IR end-point . | |
31 If | |
32 .RB ' end ' | |
33 is used instead of | |
34 .IR end-point , | |
35 .B blind-split | |
36 will proceed until the end of the input video. If you | |
37 want to discard a section of the video, you can specify | |
38 the | |
39 .I file | |
40 /dev/null. | |
41 .P | |
42 All specified | |
43 .IR end-point s, | |
44 including | |
45 .RB ' end ' | |
46 must be in strictly ascending order. | |
47 .P | |
48 The specified | |
49 .IR file s | |
50 may be of any type, except directory, including pipes | |
51 and FIFO:s. Indeed you probably want all of the to be | |
52 pipes, as saving a raw video to disc will probably fill | |
53 your disc almost immediately. If you are levering the | |
54 power of | |
55 .BR make (1) | |
56 to only rerended parts you have changes, you can | |
57 pipe the videos into | |
58 .BR blind-to-video (1) | |
59 to compress them. If you're shall does not support | |
60 process substitution or creating anonymous pipes, you | |
61 can uses FIFO:s. If you try to truncate a FIFO, it | |
62 will be flushed, if this is done after all writes have | |
63 been done, the process reading from the FIFO will think | |
64 that there no longer are any processes that have it | |
65 open for writing, assuming it, like all | |
66 .B blind | |
67 tools, have been written to treat the file as any a | |
68 regular file (which is usually have pipes are also | |
69 treated). | |
70 .SH OPTIONS | |
71 .TP | |
72 .B -L | |
73 Ignore the number of frames specified in the videos head | |
74 and read until the end or the last desired frame is reached. | |
75 If this option is used in combination with | |
76 .RB ' end ', | |
77 the last video will have an incorrect frame count written | |
78 in its head. Depending on what tools you will being using, | |
79 you may need to save that video into a regular file and | |
80 rewrite its head with | |
81 .BR blind-rewrite-head (1). | |
