Available on crate features VTFrameProcessorConfiguration and objc2 only.

The VTFrameProcessorConfiguration protocol describes the configuration of a processor to be used during a video processing session.

VTFrameProcessorConfiguration protocol conformance is used to start an frame processing session. These properties can be queried on an implementation conforming to VTFrameProcessorConfiguration without starting a session.

Provided Methods

unsafe fn processorSupported() -> u8

where Self: Sized + ClassType,

Returns a Boolean indicating whether the processor supported on the current config.

unsafe fn frameSupportedPixelFormats(&self) -> Retained<NSArray<NSNumber>>

where Self: Sized + Message,

Available on crate feature objc2-foundation only.

Returns a list of supported pixel formats for the current configuration

unsafe fn sourcePixelBufferAttributes(&self) -> Retained<NSDictionary>

where Self: Sized + Message,

Available on crate feature objc2-foundation only.

Returns a dictionary of CVPixelBuffer attributes which source and reference frames passed to the processor must conform to.

unsafe fn destinationPixelBufferAttributes(&self) -> Retained<NSDictionary>

where Self: Sized + Message,

Available on crate feature objc2-foundation only.

Returns a dictionary of CVPixelBuffer attributes which output frames passed to the processor must conform to.

unsafe fn nextFrameCount(&self) -> NSInteger

where Self: Sized + Message,

returns the number of “next” frames that this processor requires for processing.

unsafe fn previousFrameCount(&self) -> NSInteger

where Self: Sized + Message,

returns the number of “previous” frames that this processor requires for processing.

unsafe fn maximumDimensions() -> CMVideoDimensions

where Self: Sized + ClassType,

Available on crate feature objc2-core-media only.

returns the maximum dimension for a sourceFrame for the processor

unsafe fn minimumDimensions() -> CMVideoDimensions

where Self: Sized + ClassType,

Available on crate feature objc2-core-media only.

returns the minimum dimension for a sourceFrame for the processor
