What is a OGX file?
Multiplexed Ogg media container
OGX files are multiplexed media files saved with the OGG container format. OGX files are very similar to OGG files, but can have multiple media streams that are encoded using different codecs. OGX files were designed to replace the older OGG Vorbis format. The OGX file is primarily associated with OGG files created by Xiph.Org Foundation. The file format can multiplex a number of separate independent open source CODECs for audio, video and text (e.g., subtitles). Ogg's various CODECs have been incorporated into a number of different free and commercial media players as well as portable media players from different manufacturers.
