## Detailed Description

Packet containing compressed media data (audio or video).

## Member Function Documentation

## ◆ codec()

virtual const char* nx::sdk::analytics::ICompressedMediaPacket::codec | ( |  | ) | const
| pure virtual

Returns
  Null-terminated ASCII string containing the MIME type corresponding to the packet data compression. For the video data, the following MIME types are available:
  - "video/h264" for H264 streams
  - "video/hevc" for H265/HEVC streams
  - "video/mpeg4" for MPEG-4 streams
  - "video/mjpeg" for MJPEG streams

For the metadata, check the Onvif documentation.

## ◆ context()

Ptr<const IMediaContext> nx::sdk::analytics::ICompressedMediaPacket::context | ( |  | ) | const
| inline

Returns
  Pointer to the codec context, or null if not available.

## ◆ data()

virtual const char* nx::sdk::analytics::ICompressedMediaPacket::data | ( |  | ) | const
| pure virtual

Returns
  Pointer to the compressed data.

## ◆ dataSize()

virtual int nx::sdk::analytics::ICompressedMediaPacket::dataSize | ( |  | ) | const
| pure virtual

Returns
  Size of the compressed data in bytes.

## ◆ flags()

virtual MediaFlags nx::sdk::analytics::ICompressedMediaPacket::flags | ( |  | ) | const
| pure virtual

Returns
  Packet media flags.

## ◆ getContext()

virtual const IMediaContext* nx::sdk::analytics::ICompressedMediaPacket::getContext | ( |  | ) | const
| protected pure virtual

Called by context()
