6 oggCut - extracts parts of an ogg file (.ogv, .ogg and .oga)
7
9 oggCut [options] inputfile outputfile
10
12 oggCut creates a new ogg file named outputfile as a subpart of the
13 original file named inputfile
14
15 oggCut is able to cut video (theora) only files, audio (vorbis) only
16 files or files with both video and audio streams.
17
18 The start and end time for the cut area must be given in milliseconds
19 with the options -s and -e.
20
21 As a video stream consists of I‐frames (which are full pictures) and P‐
22 frames (which are delta pictures to the leading I‐frame) the oggCut
23 algorithm searches for the first I‐frame. If a video file would start
24 with a p‐frame, the player is not able to interpret this picture, as
25 the leading I‐frame (on where it is based) is not available. oggCut
26 starts the I‐frame search at the start time given by the -s option. So
27 expect a shorter video time than the calculated seconds for the new
28 file.
29
30 oggCut does not do any reencoding, therefore the output quality is com‐
31 pletely the same as from the input file.
32
33 For those involved into the ogg container format: The file is cut on
34 packet basis, not on page basis.
35
36 There is another tool called oggCut out in the internet with a differ‐
37 ent synopis. This one has not been written by the author of this tool
38 you are actually using.
39
40
42 -s Cut start position in ms. If the input file is a video file, the
43 cut area starts with the next keyframe found. Default: 0
44
45 Example: -s 5000
46
47
48 -l Length of the cut area in ms. If -e is also given, the length is
49 ignored.
50
51 Example: -l 10000
52
53
54 -e Cut end position in ms. If -l is also used, the end position is
55 prefered. If the end position is set to -1, the end of the
56 stream is assumed.
57
58 Default: -1
59
60 Example: -e 20000
61
62
63 -i Input file and output file set (alternative). These parameters
64 can be used alternatively. They are overwritten by the arguments
65 after the options. If there is one argument given, it is used as
66 the input file (and overwrites a file given with -i). If there
67 are two arguments, the input and output files from the -i and -o
68 option values are overwritten.

72 oggCut -s 1000 -e 21000 myVideo.ogv myOutput.ogv
73
74 Creates a new video called myOutput.ogv from the video myVideo.ogv
75 starting after 1 second ending after 21 seconds
