Intel i263 codec has special 8-byte dummy frames that should not be decoded,
so do not even attempt to decode them and skip them instead.

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.

This avoids the following libass warning when using the subtitles
filter: "Neither PlayResX nor PlayResY defined. Assuming 384x288"
Subtitles tests change because the output is ASS and the PlayRes[XY]
ends up in the output.
POSIX gurantees >=32bit so it all fits in signed int
Also >=32bit ints are assumed througout the codebase
