Class CMTagCategory

  • public final class CMTagCategory
extends java.lang.Object
    [@enum] CMTagCategory An enum indicating the available CMTagCategory identifiers that can be used to distinguish the tag from other kinds. Different kinds of CMTags may be defined or registered. Each will be associated with a category. CMTags with the same CMTagCategory will have the same kinds of values. The category serves as a namespace. [@constant] kCMTagCategory_Undefined Indicates there is no category specified for this value or it could not be determined. CMTags should typically not have this category except as sentinel values. [@constant] kCMTagCategory_MediaType Value is an OSType holding a CMMediaType. [@constant] kCMTagCategory_MediaSubType Value is an OSType holding a media subtype such as a video codec type. [@constant] kCMTagCategory_TrackID Value is a CMPersistentTrackID for a corresponding asset. [@constant] kCMTagCategory_ChannelID Value is the CMVideoTarget/CMVideoReceiver channel identifier. [@constant] kCMTagCategory_VideoLayerID Value is a signed 64-bit integer specifying the video layer identifier. [@constant] kCMTagCategory_PixelFormat Indicates the pixel format of the buffer or channel, if pixel-based. The type is an OSType corresponding to a pixel format (i.e., a kCVPixelFormatType_* type). [@constant] kCMTagCategory_PackingType Indicates this channel is packed in some way (e.g., frame packed, texture atlas). The value is an OSType carrying kCMPackingType_* constants. [@constant] kCMTagCategory_ProjectionType Indicates textures are related to a kind of texture projection (e.g., equirectangular). The value is an OSType carrying one of the kCMProjectionType_* constants. [@constant] kCMTagCategory_StereoView Indicates this channel is related to carrying stereographic views. The value is a Flags value carrying one of the kCMTagStereoViewComponent_* constants. [@constant] kCMTagCategory_StereoViewInterpretation Indicates this channel has non default stereo view interpretation (e.g., stereo eye view order is reversed.) Tags with this category will typically be associated with tags of category kCMTagCategory_StereoView. This tag alone however does not indicate which stereo eyes are present. The value is a Flags value carrying one of the kCMTagStereoInterpretationOption_* constants. API-Since: 17.0
