EdgeVisDecoderSDK::H264Frame Class Reference
Detailed Description
An H264Frame object provides H.264 (Annex B) data from the MediaStream to the applicaiton.
H.264 is standard format for highly compressed video and may be suited to recording video data to disk or providing video data to VMS applications.
Availability
Available in version 7.2 of Decoder SDK. Requires a server version greater than 6.0

Member Function Documentation
| DB_EDGEVIS_SDK int32_t EdgeVisDecoderSDK::H264Frame::GetLength | ( | ) | const |
Will return the length of the byte array representing the H.264 frame.
- Returns
- The length of the H.264 frame
| DB_EDGEVIS_SDK byte_array EdgeVisDecoderSDK::H264Frame::GetBytes | ( | ) | const |
Get a pointer to the byte array representing the entire H264Frame.
If the frame is an I-frame, this includes the SPS and PPS values.
- Returns
- The entire H.264 frame data.
| DB_EDGEVIS_SDK H264FrameType EdgeVisDecoderSDK::H264Frame::GetFrameType | ( | ) | const |
Determine the type of this H.264 frame.
An H.264 frame may be either H264_I_Frame or H264_P_Frame.
- Returns
- The H.264 frame type.
| DB_EDGEVIS_SDK std::wstring EdgeVisDecoderSDK::H264Frame::GetSDP | ( | ) | const |
Retrieve the Session Description Protocol including SPS and PPS for this H.264 frame.
- Returns
- A string containing the SDP configuration for this frame. The string contains "sprop-parameter-sets=" and is followed by the SPS and PPS as a base64 encoded string.
