   3 Subject: Add sampling rate sanity check to avoid crash.

   5 Bug-Debian: https://bugs.debian.org/716613

   7
   8 Input files with sampling rate 0 are useless and can make oggenc crash because neither oggenc itself nor libvorbis are prepared for this case. A sanity check lets the program refuse those inputs gracefully without crash.
