Static kCMSampleBufferConsumerNotification_BufferConsumed 

pub unsafe static kCMSampleBufferConsumerNotification_BufferConsumed: &'static CFString

Available on crate feature CMSampleBuffer only.

Posted when a CMSampleBuffer that has kCMSampleBufferAttachmentKey_PostNotificationWhenConsumed is consumed.

After an object consumes a CMSampleBuffer that has a kCMSampleBufferAttachmentKey_PostNotificationWhenConsumed attachment, it should post kCMSampleBufferConsumerNotification_BufferConsumed with itself as the notifyingObject and the attachment value as the payload. Such an attachment value must be a CFDictionary but the contents are client-defined.

Note that a NULL refcon cannot be attached to a CMSampleBuffer.
