Is there any way to recognize the camera device using HDMI cable(without USB)?

asked 2019-01-06 22:54:18 -0500

Hello, I'm studying face recognition and classification.

I want to capture people's face clearly in real time, but most of the pc webcams print images by 30fps, so most of the faces are blurred or distorted.

To solve this problem, I want to use action cams which have more than 60fps options(120fps), but these devices are only have HDMI cable.

How can I recognize the camera as a camera device on linux? (for example, using cv2.VideoCapture(0) ) or is there any way to transfer HDMI cabled frames to the computer in real time?

Thank you for your any help!

Video ports are one way ports, they are either inputs or outputs not both.

I would say that is the way with audio ports as well, but the 3.5 jacks can be assigned as a headphone/speaker out or mic/line in input. On most anything else though audio ports are strictly an input or an output as well. Check out this article about cables to know more about the working of HDMI cables.
