Attributes

codecType
The codec type of the video:
  • VIDEO_CODEC_VP8(1): VP8.
  • VIDEO_CODEC_H264(2): H.264.
  • VIDEO_CODEC_H265(3): (Default) H.265.
Note: In certain scenarios, such as low resolution of the captured video stream or limited device performance, the SDK automatically adjusts to the H.264 encoding format.
width
Width (pixel) of the video frame.
height
Height (pixel) of the video frame.
framesPerSecond

The number of video frames per second.

When this parameter is not 0, you can use it to calculate the Unix timestamp of externally encoded video frames.

frameType
The video frame type.
  • 0: (Default) VIDEO_FRAME_TYPE_BLANK_FRAME, a blank frame.
  • 3: VIDEO_FRAME_TYPE_KEY_FRAME, a key frame.
  • 4:VIDEO_FRAME_TYPE_DELTA_FRAME, a Delta frame.
  • 5:VIDEO_FRAME_TYPE_B_FRAME, a B frame.
  • 6: VIDEO_FRAME_TYPE_UNKNOW, an unknown frame.
rotation
Rotation information of the video frame, as the following:
  • 0: (Default) 0 degree.
  • 90: 90 degrees.
  • 180: 180 degrees.
  • 270: 270 degrees.
trackId
Reserved for future use.
The track ID. Used in scenarios with multiple video tracks in the channel.
captureTimeMs
The Unix timestamp (ms) for capturing the external encoded video frames.
uid
The user ID to push the externally encoded video frame.
streamType
The type of video streams.
  • VIDEO_STREAM_HIGH(0): High-quality stream, that is, a high-resolution and high-bitrate video stream.
  • VIDEO_STREAM_LOW(1): Low-quality stream, that is, a low-resolution and low-bitrate video stream.
