Detailed Description

Utils for determining the device capabilities.

Method Documentation

configureForHighestFrameRate()

- (void) configureForHighestFrameRate

Configures this device for the highest frame rate. This method will set the active format and reset the session preset to Input Priority.

isFrameRateSupported:()

- (BOOL) isFrameRateSupported:

(NSInteger)

frameRate

Determines if the given frame rate is supported by this device.

Parameters

frameRate

The frame rate.

Returns

YES if the frame rate is supported, NO otherwise.

isResolutionSupported:()

- (BOOL) isResolutionSupported:

(AXVideoFrameResolution)

resolution

Determines if the given standard resolution is supported by this device.

Parameters

resolution

The resolution.

Returns

YES if the resolution is supported, NO otherwise.

isVideoFrameSizeSupported:()

- (BOOL) isVideoFrameSizeSupported:

(AXVideoFrameSize)

frameSize

Determines if the given video frame size is supported by this device.

Parameters

frameSize

The video frame size.

Returns

YES if the frame size is supported, NO otherwise.

Property Documentation

bestSupportedFrameRateNSRange

- (NSRange) bestSupportedFrameRateNSRange

readnonatomicassign

Returns the best frame rate range that is supported by this device. The range's location is the min frame rate, and the length is the max frame rate.

bestSupportedFrameRateRange

- (AVFrameRateRange*) bestSupportedFrameRateRange

readnonatomicstrong

Returns the best AVFrameRateRange that is supported by this device.

bestSupportedSessionPreset

- (NSString*) bestSupportedSessionPreset

readnonatomicstrong

Returns the best supported session preset by this device.

supportedResolutions

- (NSArray<NSNumber *>*) supportedResolutions

readnonatomicstrong

Returns the list of resolutions that are supported by this device. The resolutions are boxed AXVideoFrameResolution.

supportedVideoFrameSizes

- (NSArray<NSValue *>*) supportedVideoFrameSizes

readnonatomicstrong

Returns the list of video frame sizes that are supported by this device. The frame sizes are boxed values of AXVideoFrameSize.
