I found one way to get 2d video from 3d content by using video filter, such as crop filter or stereo3d. But I don't how know the stereo3d type of 3d video. Different stereo3d type leads to differnt parameters for video filter. How to check media files contain 3d video and how to know what stereo3d type it has? Thanks!

B.R.

Yes, I think so.

Isn't this exactly what current FFmpeg does if you feed it with MVC?
