Properties

bufferType ↔ TRTCVideoBufferType
  • Field description: Video data structure type.
    • getter/setter pair
    data ↔ Uint8List
  • Field description: Video data when bufferType is TRTCVideoBufferType_Buffer, which carries the memory data blocks for the C++ layer.
    • getter/setter pair
    hashCode → int
    The hash code for this object.
    no setterinherited
    height ↔ int
  • Field description: Video height. Recommended value: please enter the height of the video data passed in.
    • getter/setter pair
    length ↔ int
  • Field description: Video data length in bytes. For I420, length = width * height * 3 / 2; for BGRA32, length = width * height * 4.
    • getter/setter pair
    rotation ↔ TRTCVideoRotation
  • Field description: Clockwise rotation angle of video pixels.
    • getter/setter pair
    runtimeType → Type
    A representation of the runtime type of the object.
    no setterinherited
    texture ↔ TRTCTexture?
  • Field description: Video data when bufferType is TRTCVideoBufferType_Texture, which carries the texture data used for OpenGL rendering.
    • getter/setter pair
    timestamp ↔ int
  • Field description: Video frame timestamp in milliseconds. Recommended value: this parameter can be set to 0 for custom video capturing. In this case, the SDK will automatically set the timestamp field. However, please "evenly" set the calling interval of sendCustomVideoData.
    • getter/setter pair
    videoFormat ↔ TRTCVideoPixelFormat
  • Field description: Video pixel format.
    • getter/setter pair
    width ↔ int
  • Field description: Video width. Recommended value: please enter the width of the video data passed in.
    • getter/setter pair
