After you enable this feature, the system automatically plays the stream over a degraded protocol such as HTTP Live Streaming (HLS) or HTTP Flash Video (HTTP-FLV) when your browser does not support RTC or stream pulling over RTS fails. FLV-based playback has a higher priority because it imposes lower latency than HLS-based playback. HLS-based playback is used when your browser does not support RTC or FLV.

This feature is enabled by default. To disable this feature, specify false for this parameter.

rtsFallbackType

String

The alternative RTS URL, such as a playback URL in the HLS or FLV format. By default, this parameter is left empty. In this case, the default policy is used and the system tries to play the stream over FLV first. If your browser does not support FLV, the system plays the stream over HLS.

rtsFallbackSource

We recommend that you use the default playback degradation policy. If you want to pull the stream from a specific URL, specify this parameter.

traceId

String

The unique user identifier. You can use traceId as the public tracing point to track logs. By default, the event tracking logs are uploaded and traceId is specified for user identification. If you do not specify traceId, ApsaraVideo Player SDK for Web automatically generates a UUID and saves the UUID to the browser cache.

textTracks

The WebVTT external subtitles. Sample code:

textTracks: [
  { kind: 'subtitles', label: 'Chinese', src: 'Subtitle URL', srclang: 'zh-CN', default: true },
	{ kind: 'subtitles', label: 'English (en-US)', src: 'Subtitle URL'', srclang: 'en-US' }
],

ratio

Number

The fixed aspect ratio at which the player is resized. For example, if the aspect ratio of the video is 16:9 and you specify width: "100%", ratio: 16/9, the aspect ratio of the player is the same as the video and can be proportionally resized based on the aspect ratio.

extLanguageTexts

    'zh-cn': {
      'HD': "1080p"
    }
}

      position: 'bottom-right',
      offsetY: -20,
      origin: 'content',
      src: 'b.png'
    }]

The following items describe the fields:

• src: The URL of the logo image.

• origin: The object reference. Valid values:

  • box: player

  • content: video content

• width/height: The width and height of the logo image in percentage. If you specify either the width or the height, the other parameter is specified based on the aspect ratio of the source image.
