kVTCompressionPropertyKey_AllowFrameReordering

Declaration

let kVTCompressionPropertyKey_AllowFrameReordering: CFString

Discussion

In order to encode B frames, a video encoder must reorder frames, which means that the order in which the frames are emitted and stored (the decode order) is different from the order in which they were presented to the video encoder (the display order). The default value is true. Set this value to false to prevent frame reordering.
