public final class VTCompressionSessionOptionFlags
extends java.lang.Object
When multi-pass encoding has been enabled by setting kVTCompressionPropertyKey_MultiPassStorage, you must call VTCompressionSessionBeginPass before each pass in which you call VTCompressionSessionEncodeFrame for source frames; you must call VTCompressionSessionEndPass to end each pass; and in each pass you must pass an identical sequence of source frames, frame properties and timestamps (except that source frames outside a pass' time ranges should be skipped). See kVTCompressionPropertyKey_MultiPassStorage for additional rules and guidance.
