copyPixelBufferForItemTimeItemTimeForDisplay

public CVBufferRef copyPixelBufferForItemTimeItemTimeForDisplay(CMTime itemTime,
                                                                CMTime outItemTimeForDisplay)

copyPixelBufferForItemTime:itemTimeForDisplay:

Retrieves an image that is appropriate for display at the specified item time, and marks the image as acquired.

The client is responsible for calling CVBufferRelease on the returned CVPixelBuffer when finished with it.

Typically you would call this method in response to a CVDisplayLink callback or CADisplayLink delegate invocation and if hasNewPixelBufferForItemTime: also returns YES.

The buffer reference retrieved from copyPixelBufferForItemTime:itemTimeForDisplay: may itself be NULL. A reference to a NULL pixel buffer communicates that nothing should be displayed for the supplied item time.

Parameters:

itemTime - A CMTime that expresses a desired item time.

itemTimeForDisplay - A CMTime pointer whose value will contain the true display deadline for the copied pixel buffer. Can be NULL.

delegate

public AVPlayerItemOutputPullDelegate delegate()

[@property] delegate

The receiver's delegate.

delegateQueue

public NSObject delegateQueue()

[@property] delegateQueue

The dispatch queue where the delegate is messaged.

hasNewPixelBufferForItemTime

public boolean hasNewPixelBufferForItemTime(CMTime itemTime)

hasNewPixelBufferForItemTime:

Query if any new video output is available for an item time.

This method returns YES if there is available video output, appropriate for display, at the specified item time not marked as acquired. If you require multiple objects to acquire video output from the same AVPlayerItem, you should instantiate more than one AVPlayerItemVideoOutput and add each via addOutput:. Each AVPlayerItemVideoOutput maintains a separate record of client acquisition.

Parameters:

itemTime - The item time to query.

Returns:

A BOOL indicating if there is newer output.

init

public AVPlayerItemVideoOutput init()

Overrides:

init in class AVPlayerItemOutput

initWithOutputSettings

public AVPlayerItemVideoOutput initWithOutputSettings(NSDictionary<java.lang.String,?> outputSettings)

initWithOutputSettings:

Returns an instance of AVPlayerItemVideoOutput, initialized with the specified output settings, for video image output.

Parameters:

outputSettings - The client requirements for output CVPixelBuffers, expressed using the constants in AVVideoSettings.h.

For uncompressed video output, start with kCVPixelBuffer* keys in .

In addition to the keys in CVPixelBuffer.h, uncompressed video settings dictionaries may also contain the following keys:

AVVideoAllowWideColorKey

Returns:

An instance of AVPlayerItemVideoOutput.

initWithPixelBufferAttributes

public AVPlayerItemVideoOutput initWithPixelBufferAttributes(NSDictionary<java.lang.String,?> pixelBufferAttributes)

initWithPixelBufferAttributes:

Returns an instance of AVPlayerItemVideoOutput, initialized with the specified pixel buffer attributes, for video image output.

Parameters:

pixelBufferAttributes - The client requirements for output CVPixelBuffers, expressed using the constants in .

Returns:

An instance of AVPlayerItemVideoOutput.

requestNotificationOfMediaDataChangeWithAdvanceInterval

public void requestNotificationOfMediaDataChangeWithAdvanceInterval(double interval)

requestNotificationOfMediaDataChangeWithAdvanceInterval:

Informs the receiver that the AVPlayerItemVideoOutput client is entering a quiescent state.

Message this method before you suspend your use of a CVDisplayLink or CADisplayLink. The interval you provide will be used to message your delegate, in advance, that it should resume the display link. If the interval you provide is large, effectively requesting wakeup earlier than the AVPlayerItemVideoOutput is prepared to act, the delegate will be invoked as soon as possible. Do not use this method to force a delegate invocation for each sample.

Parameters:

interval - A wall clock time interval.

setDelegateQueue

public void setDelegateQueue(AVPlayerItemOutputPullDelegate delegate,
                             NSObject delegateQueue)

setDelegate:queue:

Sets the receiver's delegate and a dispatch queue on which the delegate will be called.

Parameters:

delegate - An object conforming to AVPlayerItemOutputPullDelegate protocol.

delegateQueue - A dispatch queue on which all delegate methods will be called.
