Using Communication Components > FCSetBandwidth object

FCSetBandwidth object

The FCSetBandwidth object manages the quality of cameras and microphones by setting up a global Quality Manager object (gFlashCom.quality) that has a manage and unmanage method.

The following example shows two sets of microphones and cameras being registered. The first and second parameters name the microphone and camera, respectively, that are being registered. The third parameter, which is optional, sets the aspect ratio (height/width) for the camera. The last parameter determines how bandwidth is shared. In the example, mic1/cam1 gets one-third and mic2/cam2 gets two-thirds. If the last parameter is unspecified, bandwidth is equally distributed.

gFlashCom.quality.manage(mic1, cam1, 1, 100);
gFlashCom.quality.manage(mic2, cam2, .75, 200);

Unmanaging the microphones and cameras stops the Quality Manager from automatically adjusting their quality, as shown in the following example:

gFlashCom.quality.unmanage(mic1, cam1);

If your application uses the SetBandwidth component but does not use the AVPresence component, you must use the Quality Manager object to register your microphones and cameras. The AVPresence component automatically calls the Quality Manager object.
