input: The asset writer input to which the receiver should append pixel buffers.
Currently, only asset writer inputs that accept media data of type AVMediaTypeVideo can be used to initialize a pixel buffer adaptor.
It is an error to pass a sample buffer input that is already attached to another instance of AVAssetWriterInputPixelBufferAdaptor.
sourcePixelBufferAttributes: The attributes of pixel buffers that will be vended by the input's CVPixelBufferPool.
Pixel buffer attributes keys for the pixel buffer pool are defined in <CoreVideo/CVPixelBuffer.h>. To take advantage of the improved efficiency of appending buffers created from the adaptor's pixel buffer pool, you should specify pixel buffer attributes that most closely accommodate the source format of the video frames being appended.
Pass nil if you do not need a pixel buffer pool for allocating buffers.
Returns a new pixel buffer adaptor to receive pixel buffers for writing to the output file.
To specify the pixel format type, the pixelBufferAttributes dictionary should contain a value for kCVPixelBufferPixelFormatTypeKey. For example, use kCVPixelFormatType_32BGRA as Integer for 8-bit-per-channel BGRA, or use kCVPixelFormatType_420YpCbCr8BiPlanarVideoRange as Integer for 2-plane YCbCr.
