ffmpeg | branch: master | Stefano Sabatini <stefasab at gmail.com> | Mon Sep 23 14:10:52 2013 +0200| [7bac6e5cf81b1f956f06d15546a376e32f4ea558] | committer: Stefano Sabatini

ffprobe: fix uninitialized variable warning

Fix warning:
ffprobe.c:1684:21: warning: ‘start’ may be used uninitialized in this function [-Wmaybe-uninitialized] end = start + interval->end;

The warning is a false positive, since the variable is accessed only if
has_start is set, and in that case start has been already set.
