AVVideoSettings
NSDictionary keys for configuring output video format
A video settings dictionary may take one of two forms:
- For compressed video output, use only the keys in this header, AVVideoSettings.h.
- 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:
AVVideoPixelAspectRatioKey AVVideoCleanApertureKey AVVideoScalingModeKey AVVideoColorPropertiesKey AVVideoAllowWideColorKey
It is an error to add any other AVVideoSettings.h keys to an uncompressed video settings dictionary.
