ffmpeg | branch: master | Paul B Mahol <onemda at gmail.com> | Wed Apr 17 12:31:41 2013 +0000| [2f11aa141a01f97c5d2a015bd9dbdb27314b79c4] | committer: Paul B Mahol

lavfi: remove mp=down3dright

Same funcionality is provided by stereo3d=ab[2]{l,r}:sbs[2]{l,r}.
Additional "features" are barely useful and cause crash or artifacts.
