ogminfo - Print information about streams in OGG/OGM files SYNOPSIS
ogminfo [options] inname DESCRIPTION
This program lists all streams contained in an OGM including information about the codecs used. inname Use 'inname' as the source. -v, --verbose Be verbose and show each OGG packet. See the section 'VERBOSITY LEVELS' for details. -s, --summary Will print a short summary for each stream including the total size in bytes, the bitrate, the number of packets/frames and the length in seconds. This requires the parsing of the complete file. -h, --help Show usage information. -V, --version Show version information. VERBOSITY LEVELS
The -v option can be used to increase ogminfo's verbosity level and print more information about the current file. level 0 will print only the streams it finds and their types. level 1 will also print each stream's header and comment packets' contents. These two modes will not process the whole file (as opposed to all other modes) if the comment packets are placed correctly. level 2 will print a line for each OGG packet it encounters containing the stream the packet belongs to, the payload size, the packet's granulepos, the packet's number, its start time, its end time and several flags. The flags may include 'sync_ok' or 'OUT_OF_SYNC' which indicates whether the packet's placement in the file is correct according to its granulepos. Other flags are 'IS_SYNCPOINT' or 'EOS'. level 2 and above automatically imply --summary. level 3 also prints a line whenever a new OGG page was read completely along with the page's exact position in the file it was read from. level 4 will dump the complete stream_header structure found in the header packet for any non-Vorbis stream. The levels 3 and 4 are intended for debugging purposes only. NOTES
What works: * OGM with Vorbis audio, 'normal' video (like DivX etc.), audio streams (PCM, MP3 etc.), text streams (subtitles). What not works: * Headers created by older OggDS (DirectShow) filter versions are not supported (and probably never will be). AUTHOR

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 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 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 renum- bered 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 follow- ing 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. AUTHOR
