Understanding OGX files

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.

Common uses for OGX files

  • Multi-stream media
  • Complex media files
  • Specialized multimedia applications

Who works with OGX files?

OGX files appear most often among open-source software developers, Linux users, and digital archivists who standardize on royalty-free, patent-unencumbered media formats. Accessibility and localization teams also encounter OGX when a single file bundles video, audio, and text streams such as subtitles.

OGX vs OGV: which should you use?

Both OGX and OGV use the same Ogg container from Xiph.Org; the difference is convention rather than structure. OGV is the recommended extension for standard Ogg video files, typically Theora video with Vorbis audio, while OGX is the generic extension for multiplexed Ogg files that combine multiple or nonstandard stream types, such as video plus audio plus text tracks. Choose OGV for ordinary video playback compatibility, and expect OGX when a file carries a more complex mix of streams.
