  ac3dec: Don't consume more data than the actual input packet size
Merged-by: Michael Niedermayer <michaelni@gmx.at>

If either of the deltas is too large for the multiplications to
succeed, don't use this for setting the avg frame rate.

The time scale is set in mdhd, and later validated in the
enclosing trak atom once all of its children have been parsed.

A loose mdhd atom outside of a trak atom could update the time
scale of the last stream without any validation.

This was handled properly in the normal return case at the end
of the function, but not in this special case.

Returning a value larger than the input packet size can cause
problems for certain library users.

Returning the actual input buffer size unconditionally, since
it is not guaranteed that frame_size is set to a sensible
value at this point.

  indeo: Bound-check before applying motion compensation

The added checks and one previously added check are replaced by asserts,
the conditions can only be
true when vectors are invalid or there are worse inconsistencies.
We are checking the vectors validity and there should be no
inconsistencies, thus the checks should not be needed.
Also no files are known to cause any anomalies in ffmpeg

A frame marked FRAMETYPE_NULL cannot be scalable and requires a
