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