        createSampleBufferForRequest: addingToBatch: error: Creates a sample buffer and attempts to defer I/O for its data. Attempt may fail based on generator configuration or file format. The [AVSampleBufferGeneratorBatch makeDataReadyWithCompletionHandler:] should be called once to commence I/O and load sample data for all CMSampleBuffers within a batch. Any subsequent calls to createSampleBufferForRequest:addingToBatch:error: will throw an exception.
        Parameters:
        request - An instance of AVSampleBufferRequest representing the CMSampleBuffer creation request
        batch - An instance of AVSampleBufferGeneratorBatch to contain the output sample buffer. If nil, an exception is thrown. Must be created by calling makeBatch on the same instance of AVSampleBufferGenerator. An exception will be thrown otherwise.
        outError - A pointer to an NSError object that will be populated with failure information, if sample buffer creation fails.
        Returns:
        A CMSampleBuffer object referencing the output sample buffer. The generator may defer I/O to fetch sample data depending on the source of the sample data and the generator's timebase. API-Since: 16.0

        createSampleBufferForRequest: error: Creates a sample buffer and if requested, attempts to load its data asynchronously. Attempt may fail based on generator configuration or file format. See [AVSampleBufferGenerator notifyOfDataReadyForSampleBuffer: completionHandler:] to get notified when the sample buffer data is available. If the AVSampleBufferGenerator was created with a NULL timebase, any associated AVSampleBufferRequest will default to using AVSampleBufferRequestModeImmediate. API-Since: 16.0
        Parameters:
        request - An instance of AVSampleBufferRequest representing the CMSampleBuffer creation request.
        outError - A pointer to an NSError object that will be populated with failure information, if sample buffer creation fails.
        Returns:
        A CMSampleBuffer object referencing the output sample buffer.

        initWithAsset: timebase: Creates an instance of AVSampleBufferGenerator to generate sample buffers from the specified asset. If the specified asset is an HTTP Live Streaming asset, the generator cannot create sample buffers.
        Parameters:
        asset - The asset from which sample buffers will be created.
        timebase - The generator timebase, which governs when sample data for sample buffers is loaded. If NULL, sample data is loaded synchronously.
        Returns:
        An instance of AVSampleBufferGenerator.

        An instance of an AVSampleBufferGeneratorBatch that can be used in calls to createSampleBufferForRequest:addingToBatch:error: of the same AVSampleBufferGenerator instance. API-Since: 16.0

        notifyOfDataReadyForSampleBuffer: completionHandler: Allows the client to get notified when the sample buffer data is ready, or as soon as an error has occured.
        Parameters:
        completionHandler - The completionHandler will be called, when the sample buffer data is ready, or as soon as an error has occurred.
