ogmsplit - Split OGG/OGM files into sevaral smaller OGG/OGM files
ogmsplit [options] inname
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.
- 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
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.
- -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
- -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 mode. Progress output will be terminated by \n instead of
- -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
- -h, --help
- Show this help.
- -V, --version
- Show version information.
Example: If your source file contains these four chapters:
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
CHAPTER01NAME=Chapter 02 (continued)
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.
