Structs§

CMIODeviceAVCCommandCMIOHardwareDevice: This structure allows an AVC command to be sent to a device. This is not intended to be a general purpose command interfaces, rather only for those devices which can support the “AV/C Digital Interface Command Set General Specification Version 4.1” (1394 Trade Association Document 2001012). Devices indicate whether or not they can process AVC commands via the kCMIODevicePropertyCanProcessAVCCommand property. Field: mCommand The buffer containing the AVC command bytes. Field: mCommandLength The size (in bytes) of the mCommand buffer. Field: mResponse The buffer for returning the response bytes. Field: mResponseLength The size (in bytes) of the mResponse buffer. Field: mResponseUsed The size (in bytes) of the actual number response bytes returned.
CMIODeviceRS422CommandCMIOHardwareDevice: This structure allows an RS422 command to be sent to a device. This is not intended to be a general purpose command interface, rather only for those devices which can support the RS422 protocol. Devices indicate whether or not they can process RS422 commands via the kCMIODevicePropertyCanProcessRS422Command property. Field: mCommand The buffer containing the RS422 command bytes. Field: mCommandLength The size (in bytes) of the mCommand buffer. Field: mResponse The buffer for returning the response bytes. Field: mResponseLength The size (in bytes) of the mResponse buffer. Field: mResponseUsed The size (in bytes) of the actual number response bytes returned.
CMIODeviceSMPTETimeCallbackCMIOHardwareDevice: This structure allows a client to specify a CMIODeviceGetSMPTETimeProc and its associated private data via the kCMIODevicePropertySMPTETimeCallback property. Field: mGetSMPTETimeProc The CMIODeviceGetSMPTETimeProc to invoke when SMPTE timecode information is needed. Field: mRefCon Client supplied private provided when the kCMIODevicePropertySMPTETimeCallback property was set.
CMIODeviceStreamConfigurationCMIOHardwareDevice: This structure describes the list of streams and the number of channels in each stream. Field: mNumberStreams The number of streams being described. Field: mNumberChannels An array of UInt32’s whose length is specified by mNumberStreams. Each element of the array corresponds to a stream and indicates the number of channels it has.
CMIOExtensionClientCMIOExtensionProperties: Apple’s documentation
CMIOExtensionDeviceCMIOExtensionDevice: A CMIOExtensionDevice describes a device.
CMIOExtensionDevicePropertiesCMIOExtensionDevice: A CMIOExtensionDeviceProperties describes a CoreMediaIO extension device properties.

CMIOExtensionProviderCMIOExtensionProvider: A CMIOExtensionProvider describes a CoreMediaIO extension provider.
CMIOExtensionProviderPropertiesCMIOExtensionProvider: A CMIOExtensionProviderProperties describes CoreMediaIO extension provider properties.
CMIOExtensionScheduledOutputCMIOExtensionProperties: Apple’s documentation
CMIOExtensionStreamCMIOExtensionStream: A CMIOExtensionStream describes a stream of media data.
CMIOExtensionStreamClockTypeCMIOExtensionStream: Constants indicating the clock of the stream.
CMIOExtensionStreamCustomClockConfigurationCMIOExtensionProperties: A CMIOExtensionStreamCustomClockProperties describes the parameters used to create a custom clock on the host side (as opposed to the stream using hosttime or a linked Core Audio clock.
CMIOExtensionStreamDirectionCMIOExtensionStream: Constants indicating the direction of the stream.
CMIOExtensionStreamDiscontinuityFlagsCMIOExtensionStream: Constants indicating the state of a stream discontinuity.
CMIOExtensionStreamFormatCMIOExtensionProperties: A CMIOExtensionStreamFormat describes a stream format.
CMIOExtensionStreamPropertiesCMIOExtensionStream: A CMIOExtensionStreamProperties describes a CoreMediaIO extension stream properties.
CMIOObjectPropertyAddressCMIOHardwareObject: A CMIOObjectPropertyAddress collects the three parts that identify a specific property together in a struct for easy transmission. Field: mSelector The CMIOObjectPropertySelector for the property. Field: mScope The CMIOObjectPropertyScope for the property. Field: mElement The CMIOObjectPropertyElement for the property.
CMIOStreamDeckCMIOHardwareStream: This structure is returned in response to the kCMIOStreamPropertyDeck property queries. Field: mStatus The CMIO Deck Status constant that changed. Field: mState If kCMIODeckStatusOpcode == mStatus, this can be used to determine more specific status. The values are CMIO Deck State constants. Field: mState2 if kCMIODeckStatusOpcode == mStatus, this can be used to determine more specific status. The values are device specific.
CMIOStreamScheduledOutputNotificationProcAndRefConCMIOHardwareStream: The payload for kCMIOStreamPropertyScheduledOutputNotificationProc. Field: scheduledOutputNotificationProc The procedure to call when a buffer was output Field: scheduledOutputNotificationRefCon A pointer to client data that will be passed to the scheduledOutputNotificationProc
