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.
