AVMutableMovieMBS.addMutableTracksCopyingSettingsFromTracks(existingTracks() as AVMovieTrackMBS, options as Dictionary) as AVMutableMovieTrackMBS()
Type Topic Plugin Version macOS Windows Linux Console & Web iOS
method AVMovie MBS AVFoundation Plugin 16.0 Yes No No Yes, macOS only No
Function: Adds one or more empty tracks to the target movie, copying track settings from the source tracks.
Notes:
existingTracks: An array of AVMovieTrack objects.
options: An dictionary object that contains keys for specifying options for the initialization of the new AVMutableMovieTrack objects. Currently no keys are defined; pass nil for default initialization behavior.
Returns An array of AVMutableMovieTrack objects; the index of a track in this array is the same as the index of its source track in the existingTracks array.
This method creates one or more empty tracks in the target movie and configures those tracks with settings (such as track userdata and metadata, width, height, and preferred volume) copied from the source tracks in the existingTracks array. Also, properties involving pairs of tracks (such as track references) are copied from the source tracks to the target tracks.

Type Topic Plugin Version macOS Windows Linux Console & Web iOS
method AVMovie MBS AVFoundation Plugin 16.0 Yes No No Yes, macOS only No
Function: Adds an empty track to the target movie.
Notes:
mediaType: The media type of the new track (e.g. AVMediaTypeVideo for a video track).
track: If you wish to transfer settings from an existing track, including track userdata and metadata, width, height, preferred volume, etc., pass a reference to an AVMovieTrack representing that track. Otherwise pass nil.
options: An Dictionary object that contains keys for specifying options for the initialization of the new AVMutableMovieTrack object. Currently no keys are defined; pass nil for default initialization behavior.
Returns An AVMutableMovieTrack object or nil in case of error.
The trackID of the newly added track is a property of the returned instance of AVMutableMovieTrack.

AVMutableMovieMBS.Constructor(Data as MemoryBlock, Options as Dictionary = nil)
Type Topic Plugin Version macOS Windows Linux Console & Web iOS
method AVMovie MBS AVFoundation Plugin 16.0 Yes Yes Yes Yes No
Function: Creates an AVMutableMovie object from a movie header stored in a Memoryblock/string.
Notes:
data: A memoryblock containing a movie header.
options: An dictionary object that contains keys for specifying options for the initialization of the AVMutableMovie object. Currently no keys are defined.
Error: If an error occurs creating a movie, describes the nature of the failure.

Raises exception in case of error.

You can use this method to operate on movie headers that are not stored in files. In general you should avoid loading an entire movie file with its media data into an instance of memoryblock!

By default, the defaultMediaDataStorage property will be nil and each associated AVMutableMovieTrack's mediaDataStorage property will be nil. If you want to create an AVMutableMovie from an memoryblock and then append sample buffers to any of its tracks, you must first set one of these properties to indicate where the sample data should be written.

method AVMovie MBS AVFoundation Plugin 16.0 Yes No No Yes, macOS only No
Function: Creates an AVMutableMovie object without tracks (and therefore without media).
Notes:
movie: If you wish to transfer settings from an existing movie (including movie userdata and metadata, preferred rate, preferred volume, etc.), pass a reference to an AVMovie object representing that movie.

AVMutableMovieMBS.insertTimeRange(timeRange as CMTimeRangeMBS, asset as AVAssetMBS, atTime as CMTimeMBS, copySampleData as Boolean, byref Error as NSErrorMBS) as boolean
Type Topic Plugin Version macOS Windows Linux Console & Web iOS
method AVMovie MBS AVFoundation Plugin 16.0 Yes No No Yes, macOS only No
Function: Inserts all the tracks of a timeRange of an asset into a movie.
Notes:
timeRange: The time range of the asset to be inserted.
asset: An AVAsset object indicating the source of the inserted media. Only instances of AVURLAsset and AVComposition are supported. Must not be nil.
startTime: The time in the target movie at which the media is to be inserted.
copySampleData: A boolean value that indicates whether sample data is to be copied from the source to the destination during edits. If true, the sample data is written to the location specified by the track property mediaDataStorage if non-nil, or else by the movie property defaultMediaDataStorage if non-nil; if both are nil, the method will fail and return false. If false, sample data will not be written and sample references to the samples in their original container will be added as necessary.
Note that in this case, this method will fail if the source AVAsset is not able to provide sample reference information for the original container.
Error: If the insertion fails, an error object that describes the nature of the failure.

Returns A boolean value that indicates the success of the insertion.

This method may add new tracks to the target movie to ensure that all tracks of the asset are represented in the inserted timeRange.
Existing content at the specified startTime will be pushed out by the duration of timeRange.

AVMutableMovieMBS.mutableTrackCompatibleWithTrack(track as AVAssetTrackMBS) as AVMutableMovieTrackMBS
Type Topic Plugin Version macOS Windows Linux Console & Web iOS
method AVMovie MBS AVFoundation Plugin 16.0 Yes No No Yes, macOS only No
Function: Provides a reference to a track of a mutable movie into which any time range of an AVAssetTrack can be inserted (via insertTimeRange:ofTrack).
Notes:
track: A reference to the AVAssetTrack from which a time range may be inserted.
Returns An AVMutableMovieTrack that can accommodate the insertion.
If no such track is available, the result is nil. A new track of the same media type as the AVAssetTrack can be created via addMutableTrackWithMediaType, and this new track will be compatible.

For best performance, the number of tracks in a movie should be kept to a minimum, corresponding to the number for which media data must be presented in parallel. If media data of the same type is to be presented serially, even from multiple assets, a single track of that media type should be used. This method, mutableTrackCompatibleWithTrack, can help the client to identify an existing target track for an insertion.
