VideoSettingsKeys class abstract
Map keys for configuring output video format.
A video settings map may take one of two forms:
- For compressed video output, use only the keys in VideoSettingsKeys.
- For uncompressed video output, start with kCVPixelBuffer* keys in <CoreVideo/CVPixelBuffer.h>.
In addition to the keys in CVPixelBuffer.h, uncompressed video settings dictionaries may also contain the following keys:
videoPixelAspectRatio
videoCleanAperture
videoScalingMode
videoColorProperties
videoAllowWideColor
It is an error to add any other keys to an uncompressed video settings map.
