macOS - uvc_open already opened about orbbecsdk HOT 22 OPEN

Following up as this is an issue for a lot of other depth camera libraries:
See the discussion here: IntelRealSense/librealsense#11815

The TLDR:

• Starting in macOS 12 UVC cameras need sudo if they are opened via libuvc.
• This is because using libuvc bypasses Apple's requirement of showing a popup to access a camera ( see: libuvc/libuvc#194 )
• To get round this you can create an empty video class extension with the vid and pid of the product, this prevents Apple locking the device and requiring sudo: https://developer.apple.com/documentation/coremediaio/overriding_the_default_usb_video_class_extension?language=objc

Reopening, as this will probably affect all supported Orbbec cameras on macOS.

Femto Mega does not support MacOS，MacOS only support Gemini 2 L、Astra 2、Gemini 2 device.

Going to close - but would absolutely love if you could get at least network access to Femto Mega working on macOS in the future 😁🙏

Hey, I am having the same issue with Astra Stereo SU3. What could be the problem?

from orbbecsdk.

I think this might be due to macOS already locking the UVC device, so the SDK cannot open the stream again.. Any thoughts?

This is a permission issue. You can use sudo to open the device with administrator privileges.

@henriquenunez - was your solution to run the example with sudo, or did you do something else?

@ofTheo It is expected that by January 30, 2024, FemtoMega will support mac OS and support both USB and network functions

We are resolving the issue， may be January 30, 2024 support mac OS.

Wow!! That's wonderful news @xcy2011sky @zhonghong322
Super excited for this - going to be incredible for our community. 🎉🙏

@ofTheo
The latest SDK version 1.9.3 has been released. The camera models FemtoMega, Gemini2, Gemini2L, and Astra2 are all now supported on the MacOS system.

@ofTheo https://github.com/orbbec/OrbbecSDK/releases/tag/v1.9.3, The OrbbecViewer tool, which supports Mac, will be released very soon.

@zhonghong322 - awesome to hear about the OrbbecViewer tool.

Can confirm USB 3.2 works on macOS but does require sudo to launch.
( This would be amazing to solve ) but I can take a look too.

from orbbecsdk.

update: it does seem the USB / sudo situation is fairly flakey on macOS.
I got it working a couple of times, but then other times it just hangs after listing the device.

not sure if this is the macOS sudo issue or something else

from orbbecsdk.

@ofTheo Have you connected the external power adapter to ensure stable power supply? If the power supply is stable, the power indicator on the back of the Femto Mega should be white.

from orbbecsdk.

@ofTheo We have updated to OrbbecSDK version 1.9.4, and the OrbbecViewer tool now supports MacOS. https://github.com/orbbec/OrbbecSDK/releases/tag/v1.9.4

Thanks @zhonghong322 - I did give the Orbbec Viewer a try on macOS and it requires a lot of steps to even get the application open.

1 - I first had to expliately allow OrbbecViewer to be run as a non signed app via Security System Preferences.
2 - Then for each dylib it was trying to load I had to explicitly approve it via the same section in System Preferences. Each time this causes the app to crash so I had to run the app as many times as there was dylib ( 10+ times ).
3 - Then I had to launch the app with Sudo.

Here you can see the permissions I had to give to each dylib

Once I did all above and running with sudo I get a hang after listing the device:

If I have the Femto Mega disconnected before launching the app the app opens as expected, but then hangs as soon as I connect the Femto Mega.

For 1) and 2) I think this could be solved by bundling the dylibs in an App Bundle and getting it Signed and Notarized as a typical Mac App.

For 3) Does the Mega need the latest firmware? I still have the firmware from when it shipped.

I hope to communicate with you about the use experience of FemtoBolt. Could you please give me an email address? Or you can contact me directly.My email [email protected];

I'm following this thread with interest as I would be very keen to have an Orbbec running native to Mac OS. I currently employ an Azure Kinect talking to a Windows GTX 1080 laptop running Kinect SDK in Unity and then send data to an M3 Max Mac over UDP. This works for skeleton data, but I'd love to be able to send video and point cloud data like this - which doesn't seem possible with this setup. On the Mac I am picking up the data in Processing 4.3 (Apple Silicon). Note the latest Mac OS upgrade 14.4.1 seems to have totally broken USB camera input, so not sure if that would represent a further barrier to getting an Orbbec to work with a Mac. I'm having to use Continuity camera to get video input to correlate to the Kinect skeleton data (not a sustainable solution).
