Is this possible in MacOS at all? I have an RX100 V and an Elgato Camlink HD, but would love to use that capture card w another cam, and use the RX100 over USB simultaneously.

It works for Mac

  brew install gphoto2
  brew install ffmpeg --with-ffplay
  gphoto2 --abilities
  # Abilities for camera             : Sony Alpha-A6300 (Control)
  # ...
  gphoto2 --stdout --capture-movie | ffmpeg -i - -vcodec rawvideo -pix_fmt yuv420p -threads 0  -f matroska - | ffplay -
I'm piping it to ffplay,so this will at least let you test your camera or you could also use it in OBS as a window source. Also, make sure your cameras usb mode is not set to "mass storage" but to a “Remote Camera Control”.

Thanks for the tip, really appreciate the actual commands. I'm wondering if anyone else is running into this:

    $ brew install ffmpeg --with-ffplay
    Usage: brew install [options] formula

    # Install flags here, nothing about --with.
    Error: invalid option: --with-ffplay

can you try piping that to gstreamer?

Looks like both gphoto2 and ffmepg are available on homebrew, worth giving it a shot for sure. FWIW - I did end up building my own ffmpeg because debian default didn't have NVIDIA support. Want me to give it a try?

I'd love it if you gave it a try! I've already spent enough hours re-compiling ffmpeg to get nvenc support :)

Yes please! Would love to use my X-T30 as a webcam on my mac.
