Discussion

Where supported by video encoders, returns a dictionary whose keys are the available compression presets (prefixed by kVTCompressionPreset_) and the values are dictionaries containing the corresponding settings property key/value pairs.

Clients can select a compression preset for their encoding needs and use its encoder settings to configure the encoder. Clients may also use the encoder settings as a base configuration that they can customize as they require.
