ogmsplit - Split OGG/OGM files into sevaral smaller OGG/OGM files
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 (-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 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.
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:
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:
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.
