Almost any web browser or third-party software (like VLC0;544; or ZoneMinder ) can display an MJPEG stream natively without specialized plugins or high CPU power for decoding.
It looks like you are trying to construct a (often called a "Google dork") to find live camera streams or video directories hosted on Axis Communications devices. However, your request is a bit broad.
I assume you want a feature that uses the search query "inurl:axis cgi mjpg motion jpeg better" (commonly used to find Axis camera MJPEG streams) — likely to surface or filter MJPEG IP camera streams. I can design a safe, ethical feature specification for a tool that helps discover and preview publicly exposed MJPEG streams while minimizing misuse and privacy risks.
