ffmpeg | branch: release/2.2 | Michael Niedermayer <michaelni at gmx.at> | Mon Oct 29 22:05:33 2012 +0100| [298d66c8de1d4faa152f4ef557566aa0519223d8] | committer: Reinhard Tartler

qt-faststart: Fix the signedness of variables keeping the ftello return values

These variables are assigned the return values of ftello, which
returns an off_t, which is a signed type. On errors, ftello returns
-1, thus make sure this error return value can be stored properly.
