mencoder to 3D separate video streams and side by side stream

[robertix@…]

mencoder to the famous 3D finepix w3
w3 make the double video streams in myvideo.avi
separate stream left first 1280 X 720 X 24 fps

ffmpeg -i video.avi 2>&1 | grep Stream

Stream #0.0: Video: mjpeg, yuvj422p, 1280x720, 24 tbr, 24 tbn, 24 tbc
Stream #0.1: Audio: pcm_s16le, 48000 Hz, 2 channels, s16, 1536 kb/s
Stream #0.2: Video: mjpeg, yuvj422p, 1280x720, 24 tbr, 24 tbn, 24 tbc

i look for the mencoder option to encode theora vorbis ogm side by side movie
to upload youtube 3D my movies

to convert side by side to anaglyph:
mencoder parallel.avi -oac copy -ovc lavc -lavcopts vcodec=mjpeg:vqscale=1 -vf stereo3d=sbsl:arcc,scale -o anaglyphe.avi

thank you

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'
