 	If the sample buffer contains a CVPixelBuffer then the choice of pixel format will affect the performance and quality of the encode. For optimal performance the format of the pixel buffer should match one of the native formats supported by the selected video encoder. Below are some recommendations:
  
-	The H.264 encoder natively supports kCVPixelFormatType_420YpCbCr8BiPlanarVideoRange and kCVPixelFormatType_420YpCbCr8BiPlanarFullRange, which should be used with video and full range input respectively. The JPEG encoder on iOS natively supports kCVPixelFormatType_422YpCbCr8FullRange. For other video codecs on OSX, kCVPixelFormatType_422YpCbCr8 is the preferred pixel format for video and is generally the most performant when encoding. If you need to work in the RGB domain then kCVPixelFormatType_32BGRA is recommended on iOS and kCVPixelFormatType_32ARGB is recommended on OSX.
+	The H.264 and HEVC encoders natively support kCVPixelFormatType_420YpCbCr8BiPlanarVideoRange and kCVPixelFormatType_420YpCbCr8BiPlanarFullRange, which should be used with 8-bit 4:2:0 video and full range input respectively; other related pixel formats in CoreVideo/CVPixelBuffer.h are ideal for 4:2:2 and 4:4:4 (and for HEVC, 10-bit). The JPEG encoder on iOS and Apple Silicon macOS natively supports kCVPixelFormatType_422YpCbCr8FullRange. If you need to work in the RGB domain then kCVPixelFormatType_32BGRA is recommended on iOS and macOS.
 
 	Pixel buffers not in a natively supported format will be converted internally prior to encoding when possible. Pixel format conversions within the same range (video or full) are generally faster than conversions between different ranges.

     Default value is AVCapturePhotoQualityPrioritizationBalanced when attached to an AVCaptureSession, and AVCapturePhotoQualityPrioritizationSpeed when attached to an AVCaptureMultiCamSession. The AVCapturePhotoOutput is capable of applying a variety of techniques to improve photo quality (reduce noise, preserve detail in low light, freeze motion, etc). Some techniques improve image quality at the expense of speed (shot-to-shot time). Before starting your session, you may set this property to indicate the highest quality prioritization you intend to request when calling -capturePhotoWithSettings:delegate:. When configuring an AVCapturePhotoSettings object, you may not exceed this quality prioritization level, but you may select a lower (speedier) prioritization level.
  
     Changing the maxPhotoQualityPrioritization while the session is running can result in a lengthy rebuild of the session in which video preview is disrupted.
+ 
+    Setting the maxPhotoQualityPrioritization to .quality will turn on optical image stabilization if the -isHighPhotoQualitySupported of the source device's -activeFormat is true.

     The same result can be accomplished with AVQueuePlayer directly, but AVPlayerLooper provides a simpler interface to loop a single AVPlayerItem with an option to specify a time range. AVPlayerLooper only supports looping for forward playback (positive player rate). Behavior is undefined for negative player rate.
