Control a camera Control a microphone
Use the WZCamera class to control camera capabilities that may vary from one camera to another.
Note: Most camera configuration options that don't vary by camera are controlled by the WZCamera class.
The WZCamera class uses the following methods to determine the capabilities supported by a particular camera.
|FrameSizes||Returns an array of the frame sizes supported by the camera.|
|hasTorch||Returns true if a camera has an associated flashlight (torch).|
|supportsFocusMode:WZCameraFocusModeLocked||Returns true if the camera supports locking the focus to the current lens position.|
|supportsFocusMode:WZCameraFocusModeAuto||Returns true if the camera supports auto-focusing to a specified point location.|
|supportsFocusMode:WZCameraFocusModeContinuous||Returns true if the camera supports continuously adjusting the focus.|
|supportsFocusMode:WZCameraExposureModeLocked||Returns true if the camera supports locking the exposure at its current value.|
|supportsFocusMode:WZCameraExposureModeAuto||Returns true if the camera supports automatically adjusting and locking the exposure to a specified value.|
|supportsFocusMode:WZCameraExposureModeContinuous||Returns true if the camera supports automatically adjusting the exposure as needed.|
The following example uses the hasTorch method:
// Enable the torch button if the current camera has a flashlight (aka torch) self.torchButton.enabled = [self.goCoderCameraPreview.camera hasTorch];
Use the torchOn property to turn the flashlight on and off.
// Turn the torch on if it is not already enabled if (!self.goCoderCameraPreview.camera.isTorchOn) self.goCoderCameraPreview.camera.torchOn = YES;
Use the audioMuted property of the WowzaGoCoder class to mute or pause audio while streaming.
// Mute the audio stream if it isn't already if (!self.goCoder.audioMuted) self.goCoder.audioMuted = newMutedState;
