the stereo3d filter does not have the ability to combine seperate streams into one video file.

there are instructions for converting seperate streams to side by side using mencoder here:

theres a lot of steps, basically you dump all frames to seperate images (so if your video is long this means 1000's of images). and then use mencoder with the -vf tile filter.

its complicated, but possible.

ffmpeg can combine two videos into a side by side stream using the pad and overlay features. i am not sure it works for files with two seperate video streams.

ffplay -f lavfi -i 'movie=dead_parrot.webm [dp]; movie=spam.webm [sp];
[dp] pad=1106:360:0:0, [sp] overlay=640:0'
