videoCompositionWithAssetApplyingCIFiltersWithHandler

public static AVMutableVideoComposition videoCompositionWithAssetApplyingCIFiltersWithHandler(AVAsset asset,
                                                                                              AVMutableVideoComposition.Block_videoCompositionWithAssetApplyingCIFiltersWithHandler applier)

videoCompositionWithAsset:options:applyingCIFiltersWithHandler:

Returns a new instance of AVMutableVideoComposition with values and instructions that will apply the specified handler block to video frames represented as instances of CIImage.

The returned AVMutableVideoComposition will cause the specified handler block to be called to filter each frame of the asset's first enabled video track. The handler block should use the properties of the provided AVAsynchronousCIImageFilteringRequest and respond using finishWithImage:context: with a "filtered" new CIImage (or the provided source image for no affect). In the event of an error, respond to the request using finishWithError:. The error can be observed via AVPlayerItemFailedToPlayToEndTimeNotification, see AVPlayerItemFailedToPlayToEndTimeErrorKey in notification payload. The client can set sourceTrackIDForFrameTiming to kCMPersistentTrackID_Invalid and frameDuration to an appropriate value in order to specify the maximum output frame rate independent of the source track timing.

The video composition will also have the following values for its properties:

- The original timing of the asset's first enabled video track will be used. - A renderSize that encompasses the asset's first enabled video track respecting the track's preferredTransform. - A renderScale of 1.0.

The default CIContext has the following properties:

- iOS: Device RGB color space - OS X: sRGB color space

Example usage:

playerItem.videoComposition = [AVMutableVideoComposition videoCompositionWithAsset:srcAsset applyingCIFiltersWithHandler: ^(AVAsynchronousCIImageFilteringRequest *request) { NSError *err = nil; CIImage *filtered = myRenderer(request, &err); if (filtered) [request finishWithImage:filtered context:nil]; else [request finishWithError:err]; }];

Parameters:

asset - An instance of AVAsset. For best performance, ensure that the duration and tracks properties of the asset are already loaded before invoking this method.

Returns:

An instance of AVMutableVideoComposition.

videoCompositionWithPropertiesOfAsset

public static AVMutableVideoComposition videoCompositionWithPropertiesOfAsset(AVAsset asset)

videoCompositionWithPropertiesOfAsset:

Returns a new instance of AVMutableVideoComposition with values and instructions suitable for presenting the video tracks of the specified asset according to its temporal and geometric properties and those of its tracks.

The returned AVMutableVideoComposition will have instructions that respect the spatial properties and timeRanges of the specified asset's video tracks. The client can set sourceTrackIDForFrameTiming to kCMPersistentTrackID_Invalid and frameDuration to an appropriate value in order to specify the maximum output frame rate independent of the source track timing. It will also have the following values for its properties:

- If the asset has exactly one video track, the original timing of the source video track will be used. If the asset has more than one video track, and the nominal frame rate of any of video tracks is known, the reciprocal of the greatest known nominalFrameRate will be used as the value of frameDuration. Otherwise, a default framerate of 30fps is used. - If the specified asset is an instance of AVComposition, the renderSize will be set to the naturalSize of the AVComposition; otherwise the renderSize will be set to a value that encompasses all of the asset's video tracks. - A renderScale of 1.0. - A nil animationTool.

If the specified asset has no video tracks, this method will return an AVMutableVideoComposition instance with an empty collection of instructions.

Parameters:

asset - An instance of AVAsset. For best performance, ensure that the duration and tracks properties of the asset are already loaded before invoking this method.

Returns:

An instance of AVMutableVideoComposition.
