Available on crate features VTFrameProcessorConfiguration and objc2 only.

The protocol that describes the configuration of a processor for a video frame processing session.

Use VTFrameProcessorConfiguration protocol conformance to start a frame processing session. You can query these properties on an implementation conforming to VTFrameProcessorConfiguration without starting a session.

Provided Methods

unsafe fn isSupported() -> bool

where Self: Sized + ClassType,

Returns a Boolean indicating whether the system supports this processor on the current configuration.

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

where Self: Sized + Message,

Available on crate feature objc2-foundation only.

List of supported pixel formats for source frames for the current configuration.

This property is not atomic.

Safety

This might not be thread-safe.

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

where Self: Sized + Message,

Available on crate feature objc2-foundation only.

Pixel buffer attributes dictionary that describes requirements for pixel buffers which represent source frames and reference frames.

Use CVPixelBufferCreateResolvedAttributesDictionary to combine this dictionary with your pixel buffer attributes dictionary.

This property is not atomic.

Safety

This might not be thread-safe.

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

where Self: Sized + Message,

Available on crate feature objc2-foundation only.

Pixel buffer attributes dictionary that describes requirements for pixel buffers which represent destination frames.

Use CVPixelBufferCreateResolvedAttributesDictionary to combine this dictionary with your pixel buffer attributes dictionary.

This property is not atomic.

Safety

This might not be thread-safe.

unsafe fn nextFrameCount(&self) -> NSInteger

where Self: Sized + Message,

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

This property is not atomic.

Safety

This might not be thread-safe.

unsafe fn previousFrameCount(&self) -> NSInteger

where Self: Sized + Message,

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

This property is not atomic.

Safety

This might not be thread-safe.

unsafe fn maximumDimensions() -> CMVideoDimensions

where Self: Sized + ClassType,

Available on crate feature objc2-core-media only.

Returns the maximum dimensions 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 dimensions for a sourceFrame for the processor.
