Hi @Balaji-Sivakumar,

if I get you right and you want to display the HDMI output of another device in your application, then you will foremost need a HDMI capture device with an appropriate SDK that allows you to real-time process the captured data.

So has you saying without an HDMI capture device we can't get any video data?

If you can only get the video data through HDMI output, then yes.
Besides that, it would be better that the capture device could support Qt's default camera backend on the platform you want.
Otherwise you may need to write your own media backend.

Or if your medical system can stream the video via network according to some live-streaming protocols, then you can use other libraries to get the video.

@Bonnie Actually I'm working around the medical system, it's capable of live-streaming the video data, but only via HDMI.

Then you need an HDMI capable capture device.
