Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
property	AVFoundation	MBS AVFoundation Plugin	14.0	✅ Yes	❌ No	❌ No	✅ Yes	All

The custom video compositor, if any. (read-only)

The custom video compositor instance that is used during image generation is accessible via this property after the value of AVPlayerItemStatusFailed is set to an AVVideoComposition instance that specifies a custom video compositor class. Any additional communication between the application and that instance of the custom video compositor, if any is required for configuration or other purposes, can only occur once that has happened.

If the value of AVPlayerItemStatusFailed is changed from an AVVideoComposition that specifies a custom video compositor class to another instance of AVVideoComposition that specifies the same custom video compositor class, the instance of the custom video compositor that was previously created will receive the renderContextChanged: message and remain in use for subsequent image generation.

This property is nil if there is no video compositor, or if the internal video compositor is in use.
Available in OS X v10.9 and later.

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
property	AVFoundation	MBS AVFoundation Plugin	13.2	✅ Yes	❌ No	❌ No	✅ Yes	All

The time at which forward playback ends.

The value indicated the time at which playback should end when the playback rate is positive (see AVPlayer's rate property).

The default value is kCMTimeInvalid, which indicates that no end time for forward playback is specified. In this case, the effective end time for forward playback is the item's duration.

The value of this property has no effect on playback when the rate is negative.

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
property	AVFoundation	MBS AVFoundation Plugin	13.2	✅ Yes	❌ No	❌ No	❌ No	Desktop, Console & Web

Indicates whether the application can be used to play the content. (read-only)

This property reports whether or not the calling application is authorized to play the content associated with the item.

Application authorization is independent of content authorization (see contentAuthorizedForPlayback) and that both must be granted in order for an application to be allowed to play protected content. Also, unlike content authorization, application authorization is not dependent on user credentials (that is, if applicationAuthorizedForPlayback is false, there are no means to obtain authorization).

This property is not key-value observable.

AVPlayerItemMBS.isAuthorizationRequiredForPlayback as boolean

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
property	AVFoundation	MBS AVFoundation Plugin	13.2	✅ Yes	❌ No	❌ No	❌ No	Desktop, Console & Web

Indicates whether or not authorization is required to play the content. (read-only)

This property reports whether authorization is required for the item's content to be played. If it does not require authorization, then none of the other authorization-related methods or properties apply (though they will return sensible values where possible).

This property is not key-value observable.

AVPlayerItemMBS.isContentAuthorizedForPlayback as boolean

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
property	AVFoundation	MBS AVFoundation Plugin	13.2	✅ Yes	❌ No	❌ No	❌ No	Desktop, Console & Web

Indicates whether the content has been authorized by the user (for example, by authorizing the content's associated account in iTunes). (read-only)

This property reports whether the user has provided the necessary credentials to the system in order for the content to be decrypted for playback.

Content authorization is independent of application authorization (see applicationAuthorizedForPlayback) and that both must be granted in order for an application to be allowed to play protected content.

This property is not key-value observable.

AVPlayerItemMBS.isPlaybackBufferEmpty as boolean

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets

AVPlayerItemMBS.isPlaybackBufferFull as boolean

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
property	AVFoundation	MBS AVFoundation Plugin	13.2	✅ Yes	❌ No	❌ No	✅ Yes	All

Indicates whether the internal media buffer is full and that further I/O is suspended. (read-only)

Despite the playback buffer reaching capacity there might not exist sufficient statistical data to support a playbackLikelyToKeepUp prediction of true.
(Read only property)

AVPlayerItemMBS.isPlaybackLikelyToKeepUp as boolean

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
property	AVFoundation	MBS AVFoundation Plugin	13.2	✅ Yes	❌ No	❌ No	✅ Yes	All

Indicates whether the item will likely play through without stalling (read-only)

This property communicates a prediction of playability. Factors considered in this prediction include I/O throughput and media decode performance. It is possible for playbackLikelyToKeepUp to indicate false while the property playbackBufferFull indicates true. In this event the playback buffer has reached capacity but there isn't the statistical data to support a prediction that playback is likely to keep up in the future. It is up to you to decide whether to continue media playback.

The time at which reverse playback ends.

The value indicated the time at which playback should end when the playback rate is negative (see AVPlayer's rate property).

The default value is kCMTimeInvalid, which indicates that no end time for reverse playback is specified. In this case, the effective end time for reverse playback is kCMTimeZero.

The value of this property has no effect on playback when the rate is positive.

AVPlayerItemMBS.seekingWaitsForVideoCompositionRendering as Boolean

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
property	AVFoundation	MBS AVFoundation Plugin	14.0	✅ Yes	❌ No	❌ No	✅ Yes	All

A Boolean value indicating whether the item's timing follows the displayed video frame when seeking with a video composition.

By default, item timing is updated as quickly as possible during seeking. Specifically, the item does not wait for new frames to be rendered when seeking during normal playback. In most situations, the latency between the completion of a seek operation and the display of a video frame at the new time is negligible. However, when video compositions are in use, the processing of video may introduce noticeable latency. Setting the value of this property to true causes the item's timing to be updated only after the corresponding video frame has been displayed. For example, this allows an AVSynchronizedLayer object associated with the item to remain in sync with the displayed video.

This property has no effect on items whose videoComposition property is nil.
Available in OS X v10.9 and later.
