Introduction
OpenViBE has a custom format for stream recording in the designer. It stores all types of data exchanged between boxes in the software, with exception of the data flow in the message interface. This format is generated by the Generic Stream Writer box and is readable by the Generic Stream Reader box
It is based on EBML specification.

Note
- Stream refers to an input/ouput of the box Generic Stream Writer/Reader. They can have different types (see stream type for more informations).
- The Max ID length is set to 10 bytes, because it allows to use 64 bits ID (default size of ID in OpenViBE).
