In libavfilter, I guess. Maybe you can get some ideas from the MPlayer
stereo3d filter, porting it should not be hard.
ffmpeg-user random tip #3
Some few multimedia formats (mpeg-1, mpeg-2:PS, DV) support physical merge 
consistency, which means you can merge two files with cat. E.g.:
cat input1.mpeg input2.mpeg > output.mpeg
