pub unsafe static kCMSampleBufferConduitNotification_InhibitOutputUntil: &'static CFStringAvailable on crate feature
CMSampleBuffer only.Expand description
Posted on a conduit of CMSampleBuffers (eg, a CMBufferQueue) to announce a coming discontinuity and specify a tag value that will be attached to the first CMSampleBuffer following the discontinuity.
The first CMSampleBuffer following the discontinuity should have a kCMSampleBufferAttachmentKey_ResumeOutput attachment with value containing the same CFNumber as this notification’s payload’s kCMSampleBufferConduitNotificationParameter_ResumeTag. The consumer should discard output data until it receives this CMSampleBuffer. If multiple kCMSampleBufferConduitNotification_InhibitOutputUntil notifications are received, the last one indicates the tag to trigger resuming.
