mac OS Support

[carrotIndustries]

So far, the USBKVM app only works on Linux and Windows. For mac OS support, at least these things need to be fixed:

• Use the appropriate gstreamer source element
• Figure out how to get the bus info from the video device
• Figure out how to get the bus info from the HID device

The bus info is required to match up video and HID device.

Happy to play beta tester.

A good start would be the output of gst-device-monitor-1.0 -i Video/Source with a USBKVM attached.

output of gst-device-monitor-1.0 -i Video/Source on macOS Sequoia 15.2 with gstreamer from Homebrew:

Interesting that there's no image/jpeg in there. Maybe modern macs are doing jpeg decoding in hardware as part of AVFoundation?

I also would be a betatester :)
