Function: The SDAVAssetExportSession class for media export.
Based on open source SDAVAssetExportSession class:

AVAssetExportSessionMBS drop-in replacement with customizable audio & video settings.

An SDAVAssetExportSessionMBS object transcodes the contents of an AVAsset source object to create an output of the form described by a specified audio and video settings.

After you have initialized an export session with the asset that contains the source media, and the output file type (outputFileType), and various other settings you can start the export running by invoking exportAsynchronously. Because the export is performed asynchronously, this method returns immediately—you can use progress to check on the progress. Depending on the capabilities of the device, some exports may be queued when multiple exports are attempted. When this happens, the status of a queued export will indicate that it's waiting (StatusWaiting).

The exportAsynchronouslyCompleted event is called whether the export fails, completes, or is cancelled. Upon completion, the status property indicates whether the export has completed successfully. If it has failed, the value of the error property supplies additional information about the reason for the failure.
Available in OS X v10.9 and later in 64-bit.
