This is possible in Linux using v4l2loopback and gphoto2.

Indeed.

I use my Sony a7r II as a webcam on Linux using gphoto2 with v4l2loopback:

    sudo modprobe v4l2loopback devices=1 exclusive_caps=1 card_label="pupcam"
    gphoto2 --stdout --capture-movie | ffmpeg -i - -vcodec rawvideo -pix_fmt yuv420p -f v4l2 /dev/video0

Why not use Canon's own EOS Webcam Utility? https://www.usa.canon.com/internet/portal/us/home/about/news...

Camera Live works with non-canon models as well, there is at least partial support for some Fuji and nikon in the alpha releases and it looks like the maintainer intends to increase support even further. The heavy lifting appears to be done in libgphoto2 which supports a ton of different models.

In terms of “why don’t you just use ____”, I have scoured the web for any way to use a Nikon as a webcam on macOS (over usb, so without dropping $120 on a camlink which is sold out everywhere now anyway), and the only other thing that exists is an app called ecamm live which costs $20/month forever. For windows and even Linux there are other more affordable or open source options.

Am I the only one with strong objections to using Zoom as a verb? Putting aside the fact that it's already a verb, which courses plenty of confusion, I can go along with using Photoshop as a verb, because it is objectively the most powerful and widely used tool with a very long legacy. But Zoom is a clunky insecure mess with impressive, but not nearly leading market share. Is this really who we want to be gifting the…

Can you facetime with it? or skype? :)

We webex pretty often.

Earlier quoted context omitted.

Elgato sells other capture cards (eg. HD60), which still seem available. I recently bought a raspberry pi hi quality camera (and lens) to tinker with, and was able to connect it to my mac via pi->hdmi->capture-card to make a nice webcam view with the bokeh effect. the total cost of this example does add up, but still cheaper than a DSLR setup.

If you use the usb gadget mode of the raspberry pi to present the PI as a USB WebCam, you can forego the HDMI-connection, and thus the need for the HDMI capture card.

I've been trying to get a FPV drone camera feed into my Windows 10 computer so OpenCV can muck around with it.

OpenCV easily recognizes Webcams, but sucks at picking up 'video adapter' kinda stuff. (That is, I'm going to be using an RCA to USB dongle, such as EasyCap.)

If you can 'trick' OpenCV into thinking a webcam is attached at the USB, everything is golden.

Can you describe this raspberry pi method of 'presenting' the device as a USB WebCam? That sounds promising...

edit: Forgot to mention OpenCV is part of a c++ 64bit program I'm writing.

It works(ish) but worked better before most of the major players locked virtual cameras out with updates. Issues with unsigned code, so then some folks started unsigning apps smh. Still works with Chrome based version of several tools, and it’s cool when it works, but definitely a bit on the fragile side. The Canon software has the same limitations and just lets you use software from a perhaps more trusted source dep…

And what is/was the point of locking out the virtual cameras?

For folks with Nikon DSLRs and Windows, there's an app called SparkoCam which uses the your camera as a video feed source and appears to the host operating system as though it were a webcam. Works for Canon as well though Canon and at resolutions higher than are currently supported by Canon's "use your camera as a webcam" software.

The best results require the use of an HDMI capture device... and all of the good ones sold out almost immediately when the quarantine started.

Please take care when using your DSLRs for video. Often the sensors are not adequately cooled for long term usage as a video camera (>30m). You have the potential to damage the sensor if it is not designed for continuous use and doesn't have proper thermal protection. Newer cameras will shut down if they get too hot, or have limits to how long you can run in video mode. Stackoverflow discussion: https://video.stackex…

That’s the first thing comes in my mind. I guess this post wasn’t created by someone loves their DSLRs

Nice! I have a Canon 70D for which I simply use:

  sudo modprobe v4l2loopback
And then the identical invocation of gphoto2 as yours. Seems gphoto2 includes a wide range of camera support.

How do you download the app? They require a serial number.

Here's a direct link: http://downloads.canon.com/webcam/EOSWebcamUtilityBeta-WIN0....

Copy/paste the link to avoid the error after clicking.

I misplaced the usb cable that came with my nikon d5000 but I was able to find a replacement on amazon yesterday that should arrive later today.
