ffmpeg | branch: master | Ronald S. Bultje <rsbultje at gmail.com> | Sun Oct 28 20:44:54 2012 -0700| [95c89da36ebeeb96b7146c0d70f46c582397da7f] | committer: Ronald S. Bultje
Use ptrdiff_t instead of int for intra pred "stride" function parameter.
This way, SIMD-optimized functions don't have to sign-extend their
stride argument manually to be able to do pointer arithmetic.
