600 // General pts/dts strategy:
602 // Getting pts and dts right with variable frame rate (VFR) and B-frames can be a
603 // bit tricky. We assume first of all that the frame rate never goes _above_
604 // <frame_rate>, which gives us a frame period N. The decoder can always decode
605 // in at least this speed, as long at dts <= pts (the frame is not attempted
606 // presented before it is decoded). Furthermore, we never have longer chains of
607 // B-frames than a fixed constant C. (In a B-frame chain, we say that the base
608 // I/P-frame has order O=0, the B-frame depending on it directly has order O=1,
609 // etc. The last frame in the chain, which no B-frames depend on, is the “tip”
610 // frame, with an order O <= C.)
612 // Many strategies are possible, but we establish these rules:
614 // - Tip frames have dts = pts - (C-O)*N.
615 // - Non-tip frames have dts = dts_last + N.
617 // An example, with C=2 and N=10 and the data flow showed with arrows:
620 // pts: 30 40 50 60 70 80
622 // dts: 10 30 20 60 50←40
627 // To show that this works fine also with irregular spacings, let's say that
628 // the third frame is delayed a bit (something earlier was dropped). Now the
629 // situation looks like this:
632 // pts: 30 40 80 90 100 110
634 // dts: 10 30 20 90 50←40
639 // The resetting on every tip frame makes sure dts never ends up lagging a lot
640 // behind pts, and the subtraction of (C-O)*N makes sure pts <= dts.
642 // In the output of this function, if <dts_lag> is >= 0, it means to reset the
643 // dts from the current pts minus <dts_lag>, while if it's -1, the frame is not
644 // a tip frame and should be given a dts based on the previous one.
