ffmpeg | branch: master | Ronald S. Bultje <rsbultje at gmail.com> | Sun Jun 26 15:52:00 2011 -0700| [0d994b2f45c08794899057ee7ca54f48218c0a53] | committer: Ronald Bultje

swscale: don't use planar output functions to write to NV12/21.

This prevents a crash when converting to NV12/21 without the bitexact
flags enabled.
