onFirstLocalVideoFrame property

void Function(VideoSourceType source, int width, int height, int elapsed)? onFirstLocalVideoFrame

Occurs when the first local video frame is displayed on the local video view. The SDK triggers this callback when the first local video frame is displayed on the local video view.

  • source The type of the video source. See VideoSourceType .
  • width The width (px) of the first local video frame.
  • height The height (px) of the first local video frame.
  • elapsed Time elapsed (ms) from the local user calling joinChannel until the SDK triggers this callback. If you call startPreview before calling joinChannel, then this parameter is the time elapsed from calling the startPreview method until the SDK triggers this callback.
