Class PublisherKit.Builder

    • Constructor Detail

      • Builder

        public Builder​(android.content.Context context)
        Instantiates a PublisherKit.Builder object.
        Parameters:
        context - The android.content.Context for the publisher.

    • Method Detail

      • name

        public PublisherKit.Builder name​(java.lang.String name)
        Sets the name of the published video. The name property for a stream published by this publisher will be set to this value (on all clients).

      • audioTrack

        public PublisherKit.Builder audioTrack​(boolean enabled)
        Sets whether to include an audio track in the published stream (true, the default) or not (false). Creating a publisher without an audio track can save CPU resources and reduce the bandwidth used by the stream.

        If you call this and pass in false, the audio subsystem will not be initialized for the publisher, and calling the PublisherKit.setPublishAudio(boolean publishAudio) method will have no effect. If your application does not require the use of audio, it is recommended to use this Builder setting rather than use the PublisherKit.setPublishAudio(boolean publishAudio) method, which only temporarily disables the audio track.

      • videoTrack

        public PublisherKit.Builder videoTrack​(boolean enabled)
        Sets whether to include an video track in the published stream (true, the default) or not (false). Creating a publisher without a video track can save CPU resources and reduce the bandwidth used by the stream.

        If you call this and pass in false, the video subsystem will not be initialized for the publisher, and calling the PublisherKit.setPublishVideo(boolean publishVideo) method will have no effect. If your application does not require the use of video, it is recommended to use this Builder setting rather than use the PublisherKit.setPublishVideo(boolean publishVideo) method, which only temporarily disables the video track.

      • audioBitrate

        public PublisherKit.Builder audioBitrate​(int bitsPerSecond)
        Sets the desired bitrate for the published audio, in bits per second. The supported range of values is 6,000 - 510,000. (Invalid values are ignored.) Set this value to enable high-quality audio (or to reduce bandwidth usage with lower-quality audio).

        The following are recommended settings:

        • 8,000 - 12,000 for narrowband (NB) speech
        • 16,000 - 20,000 for wideband (WB) speech
        • 28,000 - 40,000 for full-band (FB) speech
        • 48,000 - 64,000 for full-band (FB) mono music
        • 64,000 - 128,000 for full-band (FB) stereo music

        The default value is 40,000.

        To set other audio settings, see the AudioDeviceManager class.

        Parameters:
        bitsPerSecond - The desired bitrate of the audio, in bits per second.
        Returns:
        This Builder object.

      • enableOpusDtx

        public PublisherKit.Builder enableOpusDtx​(boolean enable)
        Whether to enable Opus DTX (true) or not (false, the default). Enabling Opus DTX can reduce bandwidth usage in streams that have long periods of silence.

        By default, Opus DTX is disabled. If this property is set to true, Opus DTX will be enabled for the publisher.

      • scalableScreenshare

        public PublisherKit.Builder scalableScreenshare​(boolean enabled)
        Whether to allow use of scalable video for a publisher that has the videoType set to PublisherKitVideoTypeScreen (true) or not (false, the default).

      • subscriberAudioFallbackEnabled

        public PublisherKit.Builder subscriberAudioFallbackEnabled​(boolean enabled)
        Whether the stream will use the subscriber audio-fallback feature (true) or not (false), for subscribers to the published stream. The subscriber audio-fallback feature is available in sessions that use the the OpenTok Media Router. With the subscriber audio-fallback feature enabled (the default), when the OpenTok Media Router determines that a stream's quality has degraded significantly for a specific subscriber, it disables the video in that subscriber in order to preserve audio quality.

        The default setting is true (the audio-fallback feature is enabled). When using the screen video type in a session that uses the OpenTok Media Server, the subscriber audio-fallback setting is set to false by default, so that the video does not drop out in subscribers.

      • build

        public PublisherKit build()
        Returns:
        Returns a new PublisherKit instance based on the PublisherKit.Builder settings.
