 I think it's the framerate that is set by the MPEG4 stream itself.  Try 
running with --gst-debug=ffmpeg:5 and look for 'Using framerate from codec'.  
If that is there, it means the MPEG4 stream specifies a framerate of 100fps.  
I had something similar with Sony's MPEG4 cameras.  It would surprise me that 
Axis does things the wrong way, but it is possible I guess...
