Feature request - Video horizontal shift (wrap)

[SLAM-ER]

I would like a transform video filter that can 'shift' the image horizontally by a number of pixels.  The part that is pushed off the screen would be 'wrapped' to join with the other side.  I would use this to set the 'home' camera position of a VR360 video file.

E.g.
Say we have a video that is 8x2 pixels and we want to shift it horizontally
Original video   
ABCDEFGH
12345678

Filtered video with 4 pixel shift
EFGHABCD
56781234

Filtered video with 2 pixel shift
GHABCDEF
78123456

Thanks
Matthew

Filter intergration into Avidemux is extremely slow. Also, this is a pretty niche request.
I would suggest considering ffmpeg. The link below explains one method.
