Comment (by ffplayscale):

 No sample file is needed. It is clear that the displayed resolution with
 sbsl and sbs2l should not be the same for any file.

 If you download the first sample http://www.3d-bee.com/2d-3d-converted-
 videos/ this command runs as expected:
 `ffplay -vf "stereo3d=sbsl:argg" conversion3d-bee-diamond-gaming.mp4`
 Since the side-by-side video uses half the horizontal resolution, the
 command above produces horizontally compressed output. The following
 command is expected to fix this:
 `ffplay -vf "stereo3d=sbs2l:argg" conversion3d-bee-diamond-gaming.mp4`
 but doesn't. The following command is a workaround:
 `ffplay -vf "stereo3d=sbsl:argg, setsar=2:1" conversion3d-bee-diamond-
 gaming.mp4`
