addVideoElement

  • addVideoElement(video: HTMLVideoElement): number
  • Makes video element parameter display this stream. This is useful when you are managing the video elements on your own

    Parameters

    • video: HTMLVideoElement

    Returns number

    1 if the video wasn't associated to any other Publisher/Subscriber and has been successfully added to this one. 0 if the video was already added to this Publisher/Subscriber. -1 if the video was previously associated to any other Publisher/Subscriber and has been successfully disassociated from that one and properly added to this one.

createVideoElement

  • createVideoElement(targetElement?: string | HTMLElement, insertMode?: VideoInsertMode): HTMLVideoElement
  • Creates a new video element displaying this stream. This allows you to have multiple video elements displaying the same media stream.

    Events dispatched

    The Publisher/Subscriber object will dispatch a videoElementCreated event once the HTML video element has been added to DOM. See VideoElementEvent
