mov: do not print string len in handler_name.

The handler name is stored as a pascal string in the QT specs (first

string export.

Also add a second length check based on the first character to avoid
overwriting an already specified handler_name (it happens with Youtube

We choose the first encoder by default and libaccplus has a

Thus leading to failure by default in many cases when it is

mxfdec: Fix regression on files from Pinnacle Thunder

The reason for this is that such files have IndexTableSegments which when parsed
cover EditUnit ranges like this:

 [0,1)
 [249,250)
 [249,377)
 [0,249)

where each interval is [IndexStartPosition,IndexStartPosition+IndexDuration).
This would be reduced to a sparse index like:

 [0,1), [249,250)

instead of the full range:

 [0,249), [249,377)
