Question: can SR300 be used as a general webcam on mac?

[jessefulton]

Required Info
Camera Model	SR300
Firmware Version	3.21.0.0
Operating System & Version	MacOS 10.13
Platform	Macbook Pro
SDK Version	2.17.0
Language	N/A
Segment	Others

Issue Description

Is it possible to use the SR300 as a general webcam in MacOS off-the-shelf applications? I can see the device as a camera option in PhotoBooth, OBS, and Chrome - however, when selected, no image appears. I am using USB 3.0 and the camera does work in realsense-viewer. I have also used it in other applications as a primary webcam on a Microsoft surface pro, I'm just hoping it can be used in this manner on a Macbook Pro.

Thanks!

I can't speak for Mac as I only have PCs, but it has always been the case with the 'front facing' RealSense camera models, including SR300, that they can operate as ordinary RGB webcams on PCs. Make sure you have the SR300 plugged into a USB 3 port.

Here is a snapshot I just took with the SR300 in Skype, using it as the video webcam.

Yes, I have confirmed that it does work on a Windows machine, but I'm specifically wondering if/how it could work as a standard webcam on macOS?

I found a case from the past where someone else asked this. The advice given by the Intel support representative was to install Librealsense 1 (now known as the Legacy version after SDK 2.0's introduction).

Of course, Librealsense 2 did not exist at the time of this answer, so I would recommend seeing first if SR300 can be recognized as a webcam with SDK 2.0 installed.

Legacy Librealsense can be found here:

I was not able to use the SR300 on a Mac without librealsense (via Skype and other standard Apps)
The same holds true for the D400 series. I suspect this is due to how the depth cameras enumerate at the firmware level.
Of course, any version of librealsense will support the SR300 (both legacy and current)

[jessefulton]

@dorodnic did you have to do anything special to get it to work? As I mentioned in the original post, the camera works fine with the realsense viewer, but if I try to select it as a camera source in any other application, it is black/empty.

Hi jessefulton,
As mentioned, the SR300 should work with the RealSense Viewer application provided by the libRealSense on Mac.
Using SR300 with standard App such as facetime is not supported.
Closing this issue, but feel free to reopen it if needed.

@jessefulton Have you managed to get the realsense working as a camera source on Mac?

I'm trying to build a browser application that uses the realsense, using chrome's Media Capture Depth Stream Extensions, but having trouble enumerating frames from the realsense on Mac (Mojave). It works perfectly fine on windows.

@mrchrisjoy nope - I gave up on it after the customer service response ☹️

I have a D435 camera and can report a similar experience. It works through librealsense but not as a UVC camera. In fact it doesn't even enumerate as a UVC camera. It enumerates as a USB device but the UVC driver seems to crash when connecting to it. This is from the Console app:
