Client Object (HWHlsClient)

startPlay

startPlay(url: string, options: StartPlayOptions): Promise<void>

[Function Description]

Starts playback. The client obtains the corresponding live stream from the server based on the entered URL.

[Request Parameters]

• url: (mandatory) String type. Ingest URL that ends with m3u8.
• options: (optional) StartPlayOptions type. If this parameter is not carried, the options data carried in the first playback start request is reused. The definition of StartPlayOptions is as follows: {
  • elementId: (mandatory) indicates the playback DOM ID.
  • objectFit: (optional) String type. Default value: cover. The following enumerated values are supported:
    • contain: prioritizes the display of all video content. The video is scaled proportionally until one side of the video window is aligned with the window border. If the video size is inconsistent with the display window size, when the aspect ratio is locked and the video is zoomed in or out to fill the window, a black bar is displayed around the zoomed-in or zoomed-out video.
    • cover: prioritizes the filling of the window. The video is scaled proportionally until the entire window is filled with video. If the video size is inconsistent with the display window size, the video stream will be cropped or the image will be stretched to fill the display window.
    • fill: The window is filled with video. If the aspect ratio of the video does not match the window, the video will be stretched to fit the window.
  • muted: (optional) Boolean type. true indicates muted; false indicates unmuted. The default value is false.
  • sessionId: This parameter does not need to be transferred.
  • showLoading: (optional) Boolean type. Indicates whether to enable the loading display effect. true indicates that the loading display effect is enabled. The default value is false. When this parameter is set to true, the loading effect upon playback start will also be enabled. The loading effect upon buffering during playback needs to be set based on the LOADING_CONFIG in the setParameter API.
    

    • The QQ browser on Android devices does not support this function.
    • You are advised to leave showLoading blank or set it to false.
  • autoPlay: (optional) Boolean type. true indicates that the autoplay function is enabled. false indicates that the autoplay function needs to be manually triggered. The default value is true.
  • poster: (optional) The object definition is as follows: {
    • url: (optional) String type. Sets the complete address of the thumbnail image to be played. The image must be in JPG, PNG, or static GIF format, the size cannot exceed 1 MB, and the resolution cannot exceed 1920 x 1080. The file name cannot contain Chinese characters.
    • mode: (optional) String type. The default value is cover. The following enumerated values are supported: {
      • fill: The window is filled with video. If the aspect ratio of the video does not match the window, the video will be stretched to fit the window.
      • crop: original size of the video thumbnail. If the thumbnail exceeds the playback area, the excess part is cropped. Otherwise, the thumbnail is displayed in the middle of the playback window.

      }

    • startEnable: (optional) Boolean type. Indicates whether to display the thumbnail when the playback starts. The options are true and false. The default value is false. This parameter takes effect only in non-autoplay scenarios.
    • pauseEnable: (optional) Boolean type. Indicates whether to display the thumbnail on the playback page when the video is paused. The options are true and false. The default value is false.
