Class CMStereoViewInterpretationOptions

  • public final class CMStereoViewInterpretationOptions
extends java.lang.Object
    Flags used with kCMTagCategory_StereoViewInterpretation tags to signal additional information that may be important to the interpretation of stereo views carried in a buffer or channel. A buffer or channel may carry one or more stereo eye views. The signaling of the presence of individual stereo eye views can be done using CMTags with a kCMTagCategory_StereoView category and correspondng kCMTagStereoViewComponent_* constants. There may however be additional signaling that is valuable beyond the presence of a stereo eye. The kCMTagCategory_StereoViewInterpretation category allows additional signaling that may be relevant for interpretation of storage, ordering or other details regarding the stereo views. A CMTag having a CMTagCategory of kCMTagCategory_StereoViewInterpretation has a value that is a set of kCMStereoViewInterpretation_* flags (see CMTagMakeWithFlagsValue()) that can be set to indicate additional aspects of the stereo view or stereo views. The absence of a flag indicates the default interpretation of that feature or aspect should occur. If a flag is set, the semantic of that feature and only that feature should be inferred. Two stereo view interpretations are currently defined. One is that the order of stereo views is the reverse of the default of left then right. Here, order can be the geometric order such as in frame packed video or in something such as storage order. The second is that buffers or channels contain views other than the left stereo eye view and the right stereo eye view. Such a view might be used as an alternative when perhaps monoscopic view is to be used instead of selecting the left or right stereo view or synthesizing something based upon the left and right stereo eye views. The absence of a kCMTagCategory_StereoViewInterpretation CMTag is meant to indicate defaults are used. Specifying kCMStereoViewInterpretation_Default is equivalent to the absence of a CMTag with category kCMTagCategory_StereoViewInterpretation. [@constant] kCMStereoViewInterpretation_Default no additional interpretation other than the default is implied by this tag. The absence of a tag of the kCMTagCategory_StereoViewInterpretation is considered equivalent to a CMTag having the kCMStereoViewInterpretation_Default value. [@constant] kCMStereoViewInterpretation_StereoOrderReversed the order of the stereo left eye and stereo right eye are reversed from the default of left being first and right being second in whatever geometric sense or storage sense that might imply. If set to 0, the order is the default left and then right eye. [@constant] kCMStereoViewInterpretation_AdditionalViews one or more additional views may be present beyond stereo left and stereo right eyes (e.g,. a “centerline” view). If set to 0, there are no additional views beyond the stereo views or no additional views can be determined to exist. API-Since: 17.0
