The WZCamera
class is used to interface with a device camera. While many of the camera configuration options, such as setting the frame size, are controlled through the WZCameraView
class, WZCamera
is used for control of capabilities that may vary from one camera to another.
The table below describes the properties of the WZCamera
class that can be used to determine the capabilities supported by a particular camera.
frameSizes |
An array of the frame sizes supported by the camera |
hasTorch |
True if the camera has an associated flashlight, or torch. |
supportsFocusMode:WZCameraFocusModeLocked |
Returns true if the camera supports locking the focus at the lens' current position. |
supportsFocusMode:WZCameraFocusModeAuto |
Returns true if the camera supports auto focusing and locking it at a specified screen location. |
supportsFocusMode:WZCameraFocusModeContinuous |
Returns true if the camera supports automatically adjusting the focus as needed. |
supportsFocusMode:WZCameraExposureModeLocked |
Returns true if the camera supports locking the exposure at it's current value. |
supportsFocusMode:WZCameraExposureModeAuto |
Returns true if the camera supports automatically adjusting the exposure and locking it at a specified screen location. |
supportsFocusMode:WZCameraExposureModeContinuous |
Returns true if the camera supports automatically adjusting the exposure as needed. |
// Enable the torch button if the current camera has a flashlight (aka torch)
self.torchButton.enabled = [self.goCoderCameraPreview.camera hasTorch];
The table below describes the methods of the WZCamera
class that can be used to determine the capabilities supported by a particular camera.
getSupportedFrameSizes() |
Returns an array consisting of the frame sizes supported by the camera |
hasCapability(WZCamera.TORCH) |
Returns true if the camera has an associated flashlight, or torch. |
hasCapability(WZCamera.FOCUS_MODE_AUTO) |
Returns true if the camera supports auto focusing to a specified point location. |
hasCapability(WZCamera.FOCUS_MODE_CONTINUOUS) |
Returns true if the camera supports continuously adjusting the focus. |
// Enable the torch button if the current camera has a flashlight (aka torch)
WZCamera activeCamera = this.goCoderCameraView.getCamera();
mBtnTorch.setEnabled(activeCamera.hasCapability(WZCamera.TORCH));
The torchOn
property is used to turn a camera's flashlight on or off.
// Turn the torch on if it is not already enabled
if (!self.goCoderCameraPreview.camera.isTorchOn)
self.goCoderCameraPreview.camera.torchOn = YES;
The isTorchOn
and setTorchOn
methods are used to determine the state of a camera's flashlight and to turn it on or off.
// Turn the torch on if it is not already enabled
WZCamera activeCamera = this.goCoderCameraView.getCamera();
if (!activeCamera.isTorchOn())
activeCamera.setTorchOn(mBtnTorch.toggleState());
The audioMuted
property of the WowzaGoCoder
class is used to mute, or pause, audio from being sent while streaming.
// Mute the audio stream if it isn't already
if (!self.goCoder.audioMuted)
self.goCoder.audioMuted = newMutedState;
The muteAudio
method of the WowzaGoCoder
class can be used to mute, or pause, audio from being sent while streaming.
// Mute the audio stream if it isn't already
if (!this.goCoder.isMuted())
this.goCoder.muteAudio = newMutedState;
