This patch brings ecological and economical "Transcode once at 100% CPU - view many at ~20% CPU load" 3D (H)SBS, etc, media to the most advanced (2007) green-magenta eyes friendly anaglyph 3D projection method support using Eric Dubois' high quality method for people who want to avoid expensive resources consumed by (nice trying) real time conversion stereoscopic media players at every playback or expensive special 3D displays and 3D TV sets with polariser/shutter/no glasses without DVI-D inputs and more restrictions accepted by only ~5% of western TV/video users until today.
Red-cyan (1970,2001) dubois method has been already implemented by the original author, added -topic-.
Usage example to transcode 3D HSBSR h.264 format to anaglyph green-magenta 3D in MPEG4 (See source code for enum encoded stereo3d filter arguments, defaults to MPlayer2 "sbs2l:agmd" now):
$ ffmpeg -i test.3D.HSBS[R].x264.mp4 -c:a copy -vf mp=stereo3d=17:7 -qscale:v 8 test.3D.agmd.sbs2r.mp4
OpenGL MPlayer1/2 output is suggested for best color display results (i915/i965GM GPUs).
