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