Discussion
When you issue a photo capture request, you can separately specify the format for capturing or encoding image data and the container format for producing output files containing that data. However, each file type supports only a specific set of image data types.
After choosing a file type from the availablePhotoFileTypes array, use this method to find a compatible image data codec before creating a photo settings object.
