1 .TH BLIND-SPLIT 1 blind 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). 82 .SH SEE ALSO 83 .BR blind (7), 84 .BR blind-from-video (1), 85 .BR blind-to-video (1), 86 .BR blind-cut (1), 87 .BR blind-concat (1), 88 .BR blind-disperse (1), 89 .BR blind-split-cols (1), 90 .BR blind-split-rows (1), 91 .BR blind-rewrite-head (1) 92 .SH AUTHORS 93 Mattias Andrée 94 .RI < maandree@kth.se >
