Annodex format basics

Terminology

libannodex introduces terminology directly related to Annodex format, and also borrows some terminology from the underlying Ogg framework. Ogg is a non-heirarchical container format developed by Monty at Xiph.Org, originally for the Ogg Vorbis audio codec.

Managing multitrack data

Annodex format allows time-synchronous interleaving of multiple data tracks such as audio, video and annotations. Each track is uniquely identified by a serial number or serialno in Ogg terminology.

A random serial number will be assigned to each track automatically.

Time: video frames, sampling rates etc.

All data contained within Annodex tracks must be timed. Annodex format introduces the generic concept of granulerate to describe such things as framerates and sampling rates.
