Method Detail

videoCompositionShouldContinueValidatingAfterFindingEmptyTimeRange

default boolean videoCompositionShouldContinueValidatingAfterFindingEmptyTimeRange(AVVideoComposition videoComposition,
                                                                                   CMTimeRange timeRange)

videoComposition:shouldContinueValidatingAfterFindingEmptyTimeRange:

Invoked by an instance of AVVideoComposition when validating an instance of AVVideoComposition, to report a timeRange that has no corresponding video composition instruction.

Returns:

An indication of whether the AVVideoComposition should continue validation in order to report additional problems that may exist.

videoCompositionShouldContinueValidatingAfterFindingInvalidTimeRangeInInstruction

default boolean videoCompositionShouldContinueValidatingAfterFindingInvalidTimeRangeInInstruction(AVVideoComposition videoComposition,
                                                                                                  AVVideoCompositionInstruction videoCompositionInstruction)

videoComposition:shouldContinueValidatingAfterFindingInvalidTimeRangeInInstruction:

Invoked by an instance of AVVideoComposition when validating an instance of AVVideoComposition, to report a video composition instruction with a timeRange that's invalid, that overlaps with the timeRange of a prior instruction, or that contains times earlier than the timeRange of a prior instruction.

Use CMTIMERANGE_IS_INVALID, defined in CMTimeRange.h, to test whether the timeRange itself is invalid. Refer to headerdoc for AVVideoComposition.instructions for a discussion of how timeRanges for instructions must be formulated.

Returns:

An indication of whether the AVVideoComposition should continue validation in order to report additional problems that may exist.

videoCompositionShouldContinueValidatingAfterFindingInvalidTrackIDInInstructionLayerInstructionAsset

default boolean videoCompositionShouldContinueValidatingAfterFindingInvalidTrackIDInInstructionLayerInstructionAsset(AVVideoComposition videoComposition,
                                                                                                                     AVVideoCompositionInstruction videoCompositionInstruction,
                                                                                                                     AVVideoCompositionLayerInstruction layerInstruction,
                                                                                                                     AVAsset asset)

videoComposition:shouldContinueValidatingAfterFindingInvalidTrackIDInInstruction:layerInstruction:asset:

Invoked by an instance of AVVideoComposition when validating an instance of AVVideoComposition, to report a video composition layer instruction with a trackID that does not correspond either to the trackID used for the composition's animationTool or to a track of the asset specified in -[AVVideoComposition isValidForAsset:timeRange:delegate:].

Returns:

An indication of whether the AVVideoComposition should continue validation in order to report additional problems that may exist.

videoCompositionShouldContinueValidatingAfterFindingInvalidValueForKey

default boolean videoCompositionShouldContinueValidatingAfterFindingInvalidValueForKey(AVVideoComposition videoComposition,
                                                                                       java.lang.String key)

videoComposition:shouldContinueValidatingAfterFindingInvalidValueForKey:

Invoked by an instance of AVVideoComposition when validating an instance of AVVideoComposition, to report a key that has an invalid value.

Returns:

An indication of whether the AVVideoComposition should continue validation in order to report additional problems that may exist.
