This makes the code easier to understand as the scope of the variable is
smaller.

Its not removed as the code which uses this is out-commented too.

DTS primarly needs to be separated from PCM, and PCM can contain cliping and
overshoots at the very start which can mimic DTS headers.

If this isnt sufficient then more of the DTS stream has to be decoded
and analyzed

  h264: prevent theoretical infinite loop in SEI parsing

Conflicts:
	libavcodec/h264_sei.c

Not merged, as this would remove 2 bitstream compliance checks.
The specification does not allow the bitstream to end in the middle
of these variable length elements and we have no samples which
have such non compliant truncation either so its better to error
out. Which is simpler as well

This issue also has been fixed long ago
