Instead, store them in the context and compute on each parameter change.

We do not allow the frame parameters to change during encoding, so there
is no need to do this for each frame.

Also suggest what can be done to workaround the limitation.

Based on avcodec.h documentation.

The order of error codes will be useful in my future fateserver patches.

Normally, a Laplace distribution is more typical of the residuals
encoded, but for noisy input, it's both better and simpler to be
safe and use a 1/d^2 distribution. Second hunk could use some
renormalization but it has effectively little impact.
