ffmpeg | branch: master | Michael Niedermayer <michaelni at gmx.at> | Sun Jun 12 21:53:22 2011 -0400| [0af8a71d66305874bd6f0ebc84ebf99339b6a5d3] | committer: Ronald S. Bultje
swscale: fix JPEG-range YUV scaling artifacts.
YUV planes were marked as uint16_t, but they contained signed data.
Fixes issue 1108 and 675.
