convenience init(videoCodecType: AVVideoCodecType, encoderSpecification: [String : any Sendable]? = nil, mediaType: AVMediaType, segmentConfigurations: [AVPlannedVideoSegmentConfiguration], assemblyTrackID: CMPersistentTrackID)

Creates an instance of AVAssetVideoTrackPlan. This initializer throws NSInvalidArgumentException in the following cases: 1. mediaType is not supported. Supported media types are AVMediaTypeVideo and AVMediaTypeAuxiliaryPicture 2. The encoder specified by videoCodecType and encoderSpecification does not support video encoding in segments - Parameters: - videoCodecType: Video codec type of the track. - encoderSpecification: A dictionary describing the characteristics of a video encoder to use. Pass nil to let the system choose an encoder. If the client provides a specification, it should omit the following keys: kVTCompressionPropertyKey_SourceFrameCount, kVTCompressionPropertyKey_MoreFramesBeforeStart, and kVTCompressionPropertyKey_MoreFramesAfterEnd, since such keys will be overwritten by the underlying implementation. - mediaType: Media type of the track. Only AVMediaTypeVideo and AVMediaTypeAuxiliaryPicture are supported. - segmentConfigurations: Segment configurations of the track. - assemblyTrackID: The trackID that identifies this track in the assemblyComposition the planner passes to the completion handler of the incremental writing session.
