trackDataReadiness(_:)
Associates a sample buffer’s data readiness with that of another sample buffer.
Declaration
func trackDataReadiness(_ sampleBufferToTrack: CMSampleBuffer) throwsParameters
- sampleBufferToTrack:
The sample buffer for which to track readiness.
Discussion
After calling this method, retrieving the value of the dataReadiness property retrieves the value from the tracked sample buffer. Likewise, calling the makeDataReady() method calls the tracked sample buffers method.
Use this method to convert a multi-sample buffer into single-sample buffer before the data is ready. The single-sample buffer tracks the data readiness of the multi-sample buffers.
