    • Method Detail

      • getInitialBitrate

        public int getInitialBitrate()
        The initial bitrate for the output video stream. By default this is `2,100,000`.

      • setInitialBitrate

        public void setInitialBitrate​(int initialBitrate)
        Sets the initial bitrate for the video stream. This must be between 100k and 8500k otherwise a IllegalArgumentException will be thrown.
        Parameters:
        initialBitrate - the desired initial bitrate

      • getMaxBitrate

        public int getMaxBitrate()
        The maximum bitrate for the output video stream. By default this is `6,000,000`.

      • setMaxBitrate

        public void setMaxBitrate​(int maxBitrate)
        Sets the maximum bitrate for the video stream. This must be between 100,000 and 8,500,000 otherwise a IllegalArgumentException will be thrown.
        Parameters:
        maxBitrate - the desired initial bitrate

      • getMinBitrate

        public int getMinBitrate()
        The minimum bitrate for the output video stream. By default this is `300,000`.

      • setMinBitrate

        public void setMinBitrate​(int minBitrate)
        Sets the minimum bitrate for the video stream. This must be between 100k and 8500k otherwise a IllegalArgumentException will be thrown.
        Parameters:
        minBitrate - the desired initial bitrate

      • getTargetFramerate

        public int getTargetFramerate()
        The target framerate of the output video stream. By default this is `30`.

      • setTargetFramerate

        public void setTargetFramerate​(int targetFramerate)
        Sets the target framerate for the video stream. This must be between 10 and 60 otherwise a IllegalArgumentException will be thrown.
        Parameters:
        targetFramerate - the desired target framerate

      • getKeyframeInterval

        public float getKeyframeInterval()
        The keyframe interval for the output video stream in seconds. By default this is `2`.

      • setKeyframeInterval

        public void setKeyframeInterval​(float keyframeInterval)
        Sets the keyframe interval for the video stream. This must be between 1 and 5 otherwise a IllegalArgumentException will be thrown.
        Parameters:
        keyframeInterval - the desired keyframe interval

      • setSize

        public void setSize​(int width,
                    int height)
        Sets the frame image size for the video stream. The width and height must both be between 160 and 1920, and the maximum total number of pixels is 2,073,600. So the smallest size you can provide is 160x160, and the largest is either 1080x1920 or 1920x1080. However something like 1920x1200 would not be supported. 1280x180 however is supported. If these restrictions are violated a IllegalArgumentException will be thrown. Note that some video encoders are unable to handle image frame sizes of less than 176x176, resulting in an inability to start the session. The recommended minimum is 176x176.
        Parameters:
        width - the desired width in pixels
        height - the desired height in pixels

      • isUseBFrames

        public boolean isUseBFrames()
        Whether the output video stream uses B (Bidirectional predicted picture) frames. By default this is `true`.

      • setUseBFrames

        public void setUseBFrames​(boolean useBFrames)

      • isUseAutoBitrate

        public boolean isUseAutoBitrate()
        Whether the output video stream will automatically adjust the bitrate based on network conditions. Use setMinBitrate(int) and setMaxBitrate(int) to specify the bounds when this is `true`. By default this is `true`.

      • setUseAutoBitrate

        public void setUseAutoBitrate​(boolean useAutoBitrate)

      • isTransparencyEnabled

        public boolean isTransparencyEnabled()
        Whether transparency is enabled for this broadcast session.

      • enableTransparency

        public void enableTransparency​(boolean enableTransparency)
        Setting this to true will enable transparency between mixer slots at the cost of some memory usage. For example, if you wanted to broadcast the rear facing camera taking up the entire view port, and then overlay the front facing camera with 30% transparency so that you can still partially see the rear facing camera under the front facing camera, this property would need to be YES. Enabling this option does increase the memory usage of the pipeline. If you are not going to use multiple mixer slots with blending, leave this as false. By default this is false.
        Parameters:
        enableTransparency - Whether to enable transparency.
