NAME
ogmsplit - Split OGG/OGM files into several smaller OGG/OGM files
SYNOPSIS
ogmsplit [options] inname
DESCRIPTION
ogmsplit can be used to easily split an OGM file after a given size.
Several OGM files will be created that each start with a keyframe.
inname Use ’inname’ as the source.
-o, --output out
Use ’out’ as the base name. Ascending part numbers will be
appended to it. Default is ’inname’. Examples:
1) If -o output.ogg is given on the command line then ogmsplit
will create output-000001.ogg, output-000002.ogg and so on.
2) If no -o option is given and the input’s name is movie.ogm
then ogmsplit will create movie-000001.ogm and so on.
The operation mode can be set with exactly one of -s, -t, -c or -p. The
default mode is to split by size (-s).
-s, --size size
Size in MiB ( = 1024 * 1024 bytes) after which a new file will
be opened (approximately). Default is 700MiB. Size can end in
’B’ to indicate ’bytes’ instead of ’MiB’.
-t, --time time
Split after the given elapsed time (approximately). ’time’
takes the form HH:MM:SS.sss or simply SS(.sss), e.g.
00:05:00.000 or 300.000 or simply 300.
-c, --cuts cuts
Produce output files as specified by cuts, a list of slices of
the form "start-end" or "start+length", separated by commas. If
start is omitted, it defaults to the end of the previous cut.
start and end take the same format as the arguments to -t.
-n, --num num
Don’t create more than num separate files. The last one may be
bigger than the desired size. Default is an unlimited number of
files. Can only be used with -s or -t.
--frontend
Frontend mode. Progress output will be terminated by \n instead
of \r.
-p, --print-splitpoints
Only print the key frames and the number of bytes encountered
before each. Useful to find the exact splitting point.
-v, --verbose
Be verbose and show each OGG packet. Can be used twice to
increase verbosity.
-h, --help
Show this help.
-V, --version
Show version information.
CHAPTER INFORMATION
ogmsplit correctly handles chapter information. During the first pass
the chapter information, if any is present, will be adjusted to match
the output files generated. Chapters that are not contained in the
current output file are removed entirely. The other chapters are
renumbered to start at 1, and their timestamps will be recalculated.
Example: If your source file contains these four chapters:
CHAPTER01=00:00:00.000
CHAPTER01NAME=Chapter 01
CHAPTER02=00:10:00.000
CHAPTER02NAME=Chapter 02
CHAPTER03=00:20:00.000
CHAPTER03NAME=Chapter 03
CHAPTER04=00:25:00.000
CHAPTER04NAME=Chapter 04
and you split after 15 minutes, then the first output file will only
contain the first two chapters as shown above, and the second output
file will contain the following two chapters and the remaining part of
the first:
CHAPTER01=00:00:00.000
CHAPTER01NAME=Chapter 02 (continued)
CHAPTER02=00:05:00.000
CHAPTER02NAME=Chapter 03
CHAPTER03=00:10:00.000
CHAPTER03NAME=Chapter 04
Note that only variable names are changed, not the chapter names
themselves. The exception is the first chapter of the second and
following files where "(continued)" is appended in order to indicate
that this is not the start of this chapter. If you want to change them
as well you’ll have to remerge the resulting file with a new chapter
file.
