* The frame info struct remembers information about each frame across calls to

* some bits of the timestamp as an index. The LSB is chosen so that two
* successive frames will have different values in the bits over any plausible
* range of frame rates (starting with bit 8 allows any frame rate slower than
* 352fps). The MSB determines the size of the array. It is chosen so that two
* frames can't use the same slot during the encoder's max frame delay so that,
* up to some minimum frame rate, frames are guaranteed to map to different
* slots (an MSB of 17 which is 2^(17-8+1) = 1024 slots guarantees no collisions
* down to a rate of 0.7 fps).
