What is this cable for ?

Yo my best friends .

i found a brand new cable on the ground in front of a market and i was wondering what it was made for

that's how the cable looks like :

for a moment i tought it was a capture card or smth , but it was way too small to be one

and when i try to google "HDMI TO USB" i always get me back to Usb to hdmi adapters ...

thanks for the help tho
