Streaming and Decoding

Streaming events is done using Metavision HAL, specifically using the I_EventsStream facility which exposes functions to start and stop the streaming as well as getting the raw events stream from the camera.

The events stream is encoded in one of the formats described here.

To decode the raw events stream, the I_Decoder facility is provided in Metavision HAL. It offers functions to decode raw buffers into decoded event buffers, which are provided via C++ callbacks registered onto the I_EventDecoder facility.

Raw Buffer Format

Raw data received from the camera are in one of the following EVT formats.

Decoded Buffer Format

Only CD and Trigger events are decoded. See more information on the data format here.
