[Carl Eugen Hoyos]

ffmpeg | branch: master | Carl Eugen Hoyos <cehoyos at ag.or.at> | Sat May  3 20:18:13 2014 +0200| [c2b0ce70add2a7dd6e792341c21278cb94820684] | committer: Carl Eugen Hoyos

Initialize riff and wav size fields to -1 instead of 0.

WMP doess not play the output files if the fields are
set to 0 and not overwritten (using pipe output).

Fixes ticket #3346.
