ogmtools are a set of utilities for Ogg Media files (OGM) manipulation, written by Moritz Bunkuns. Ogg is a container format that can contains much more than a simple Vorbis sound stream: notably, you can have a video stream, subtitles, etc. ogmtools are not meant to encode or decode anything, but will be used complementary to mplayer/mencoder or any other media encoding utility. ogmmerge will produce an OGM file from separated components, like an audio track and a video track, and ogmdemux will have the inverse behaviour. ogmsplit will cut a file into several parts, and ogminfo will print information about the file. The last tool, dvdxchap is used in combination with ogmmerge to add some special comments into the resulting OGM file to provide chaptering with the player that support it (the OggDS Windows filter takes advantage of that).
Binary packages can be installed with the high-level tool pkgin (which can be installed with pkg_add) or pkg_add(1) (installed by default). The NetBSD packages collection is also designed to permit easy installation from source.
The pkg_admin audit command locates any installed package which has been mentioned in security advisories as having vulnerabilities.
Please note the vulnerabilities database might not be fully accurate, and not every bug is exploitable with every configuration.
