NAME
oggCut - extracts parts of an ogg file (.ogv, .ogg and .oga)
SYNOPSIS
oggCut [options] inputfile outputfile
DESCRIPTION
oggCut creates a new ogg file named outputfile as a subpart of the
original file named inputfile
oggCut is able to cut video (theora) only files, audio (vorbis) only
files or files with both video and audio streams.
The start and end time for the cut area must be given in milliseconds
with the options -s and -e.
As a video stream consists of I‐frames (which are full pictures) and
P‐frames (which are delta pictures to the leading I‐frame) the oggCut
algorithm searches for the first I‐frame. If a video file would start
with a p‐frame, the player is not able to interpret this picture, as
the leading I‐frame (on where it is based) is not available. oggCut
starts the I‐frame search at the start time given by the -s option. So
expect a shorter video time than the calculated seconds for the new
file.
oggCut does not do any reencoding, therefore the output quality is
completely the same as from the input file.
For those involved into the ogg container format: The file is cut on
packet basis, not on page basis.
There is another tool called oggCut out in the internet with a
different synopis. This one has not been written by the author of this
tool you are actually using.
OPTIONS
-s Cut start position in ms. If the input file is a video file, the
cut area starts with the next keyframe found. Default: 0
Example: -s 5000
-l Length of the cut area in ms. If -e is also given, the length is
ignored.
Example: -l 10000
-e Cut end position in ms. If -l is also used, the end position is
prefered. If the end position is set to -1, the end of the
stream is assumed.
Default: -1
Example: -e 20000
EXAMPLE
oggCut -s 1000 -e 21000 myVideo.ogv myOutput.ogv
Creates a new video called myOutput.ogv from the video myVideo.ogv
starting after 1 second ending after 21 seconds
