Detailed Description

Single encoded video packet retrieved from a camera source.

The payload is laid out as Annex-B NAL units. The first packet handed back on a given source is always an IDR, with SPS/PPS (and VPS for HEVC) inlined in front, so writing successive packets to a .h264 / .hevc file produces a stream playable by any standard player.

Note

data is owned by the SDK and remains valid until the next call to RetrieveEncodedStreamPacket() on the same source, or until the camera is closed. Other calls do not invalidate the buffer. Use GetData() to copy the bytes out if you need them longer.

Functions

GetData()

byte [] GetData ( )

inline

Copies the encoded payload into a managed byte array.

Returns

The Annex-B payload, or an empty array if the packet holds no data.
