[vlc-devel] commit: Workaround another swscale bug. (Laurent Aimar )

[git version control]

vlc | branch: master | Laurent Aimar <fenrir at videolan.org> | Mon Apr 20 22:06:57 2009 +0200| [7d784bfab724acc615a3c7b490bdccc23fad4692] | committer: Laurent Aimar 

Workaround another swscale bug.

 Some RGB conversion are broken if SWS_ACCURATE_RND is not set.
This commit should be reverted when swscale is fixed (or at least a
check on the version is needed).
