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