Structs§

CMBlockBufferCMBlockBuffer: A reference to a CMBlockBuffer, a CF object that adheres to retain/release semantics. When CFRelease() is performed on the last reference to the CMBlockBuffer, any referenced BlockBuffers are released and eligible memory blocks are deallocated. These operations are recursive, so one release could result in many follow on releses.
CMBlockBufferCustomBlockSourceCMBlockBuffer: Used with functions that accept a memory block allocator, this structure allows a client to provide a custom facility for obtaining the memory block to be used in a CMBlockBuffer. The AllocateBlock function must be non-zero if the CMBlockBuffer code will need to call for allocation (not required if a previously-obtained memory block is provided to the CMBlockBuffer API). The FreeBlock() routine, if non-NULL, will be called once when the CMBlockBuffer is disposed. It will not be called if no memory block is ever allocated or supplied. The refCon will be passed to both the AllocateBlock and FreeBlock() calls. The client is responsible for its disposal (if any) during the FreeBlock() callback.
CMBufferCallbacksCMBufferQueue and CMTime: Callbacks provided to CMBufferQueueCreate, for use by the queue in interrogating the buffers that it will see.
CMBufferHandlersCMBufferQueue and CMTime and block2: Apple’s documentation
CMBufferQueueCMBufferQueue: A reference to a CMBufferQueue, a CF object that implements a queue of timed buffers.
CMClockCMSync: A timing source object.
CMFormatDescriptionCMFormatDescription: A reference to a CMFormatDescription, a CF object describing media of a particular type (audio, video, muxed, etc).
CMMemoryPoolCMMemoryPool: CMMemoryPool.h
CMMutableTagCollectionCMTagCollection: Apple’s documentation
CMPackingTypeCMTag: Constants used with kCMTagCategory_PackingType to signal the nature of any packing applied in a buffer or channel.
CMProjectionTypeCMTag: Constants used with kCMTagCategory_ProjectionType to signal the nature of a video projection carried in a buffer or channel.
CMSampleBufferCMSampleBuffer: A reference to a CMSampleBuffer, a CF object containing zero or more compressed (or uncompressed) samples of a particular media type (audio, video, muxed, etc).
CMSampleTimingInfoCMSampleBuffer and CMTime: Collection of timing info for a sample in a CMSampleBuffer. A single CMSampleTimingInfo struct can describe every individual sample in a CMSampleBuffer, if the samples all have the same duration and are in presentation order with no gaps.
CMSimpleQueueCMSimpleQueue: A reference to a CMSimpleQueue, a CF object that implements a simple lockless queue of (void *) elements.
CMStereoViewComponentsCMTag: Flags used with kCMTagCategory_StereoView tags to signal the nature of the stereo views carried in a buffer or channel.
CMStereoViewInterpretationOptionsCMTag: 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.
CMTagCMTag: An efficient structure used to label something about a resource or other media construct.
CMTagCategoryCMTag: An enum indicating the available CMTagCategory identifiers that can be used to distinguish the tag from other kinds.
CMTagCollectionCMTagCollection: A reference to a CMTagCollection, a CF object that adheres to retain/release semantics. This value type represents an unordered collection of zero or more CMTags. This type is roughly analogous to CFSetRef in that it is unordered and has operations for Boolean set math. It is however optimized for the storage of CMTag structures.
CMTagCollectionErrorCMTagCollection: The OSStatus errors returned from the CMTagCollection routines.
CMTagDataTypeCMTag: The data type for the value of the CMTag.
CMTagErrorCMTag: The OSStatus errors returned from the CMTag routines.
CMTaggedBufferGroupCMTaggedBufferGroup: An object gathering zero or more buffers (CMSampleBuffer, CVPixelBuffer) each with a CMTagCollection.
CMTaggedBufferGroupErrorCMTaggedBufferGroup: The OSStatus errors returned from the CMTaggedBufferGroup routines.
CMTimeCMTime: Rational time value represented as int64/int32.
CMTimeFlagsCMTime: Flag bits for a CMTime.
CMTimeMappingCMTime and CMTimeRange: A CMTimeMapping specifies the mapping of a segment of one time line (called “source”) into another time line (called “target”).
CMTimeRangeCMTime and CMTimeRange: A time range represented as two CMTime structures.
CMTimeRoundingMethodCMTime: Rounding method to use when computing time.value during timescale conversions.
CMTimebaseCMSync: Models a timeline under application control.
CMVideoDimensionsCMFormatDescription: Type used for video dimensions, units are pixels

CMTagCollectionApplierFunctionCMTag and CMTagCollection: A callback function that can be used to iterate over a CMTagCollection. The callback is passed a CMTag and a potentially NULL context reference that can be used to implement some operation for each tag.
CMTagCollectionTagFilterFunctionCMTag and CMTagCollection: A callback function that can be used to implement a filtering operation during iteration over a CMTagCollection. For each CMTag that satisfies the predicate, the callback should return true. Otherwise, it should return false. The callback is passed a CMTag and a potentially NULL context reference that can be used to implement some operation for each tag.
CMTagValueCMTag: 64-bit value interpreted within the context of the CMTagCategory.
