Presentation delay of current frame in units of AVCodecContext.time_base.
Set to INT_MIN when dts_sync_point unused. Otherwise, it must
contain valid non-negative timestamp delta (presentation time of a frame
must not lie in the past).
This delay represents the difference between decoding and presentation
time of the frame.
For example, this corresponds to H.264 dpb_output_delay.
