I'm trying to take two input videos (can be in avi, mp4, whatever ffmpeg supports) and combine them into a stereoscopic video with the "ffmpeg" utility that uses simple red and cyan colored glasses (anaglyph). I have tried the following statements with input files of type mp4:
ffmpeg -i left.mp4 -i right.mp4 stereo3d=al:arcc video_arcc.mp4 ffmpeg -i left.mp4 -vf "movie=right.mp4" stereo3d=al:arcc video_arcc.avi
I see error messages like:
Error message: [NULL @ 0000000003220940] Unable to find a suitable output format for 'stereo3d=al:arcc' stereo3d=al:arcc: Invalid argument
My source images are a series of JPEGs that I can convert to any input format. It would be preferrable to use left%06d.jpg" and "right%06d.jpg", but that is an extra layer of difficulty for now.
What command line options do I need for ffmpeg anaglyph red-cyan?
