liverserver.so cannot open. uv4l mjpegstream - raspberry-pi

Question

I'm having issues making a virtual camera with uv4l mjpegstream.
This mjpegstream is not a camera but rather a graphic that I created.
pi#iot:~ $uv4l --driver mjpegstream --auto-video_nr --verbosity=8 -f --uri "http://10.1.7.191/api/gfx/stream.jpg" --server-option=--port=80

The whole reason for me doing this is to convert the mjpeg stream to rtsp.
I believe I should be able to do this pretty easily. But it seems there are issues with my implementation
