USB Camera Issue on M1 Mac

[Sergii Ovcharenko]

Hey,

Im seeing a weird issue with Camera properties greyed out not allowing me to adjust exposure, color temp, saturation etc after i switched from intel mac to m1 mac.

• M1 Mac Studio
• Latest version of Openpnp
• Cameras are connected to individual ports ( i even tried to connect only one camera with other USB devices completely disconnected)
• 720p ELP cameras from Aliexpress that I tried to connected directly to Mac's USB-A ports, through USBA to USBC adapter and through Thunderbolt 4 to 4xUSB-A hub.

There is nothing in the logs other than

2022-07-02 10:52:55.592 Main INFO: Bienvenue, Bienvenido, Willkommen, Hello, Namaskar, Welkom, Bonjour to OpenPnP version 2022-06-19_21-15-55.af43024.

USB devices:

There are 2 cameras in the list but only one is physically connected.

Same cameras are working correctly with Intel based Mac and all properties are available.

Does anyone have an idea how to fix this?

So you have TWO exactly the same  720p ELP cameras?

[Sergii Ovcharenko]

I do, yes.

None of them have properties enabled even if I connect only one of them with all other USB devices disconnected.

I see you have Buss 3.1 ??  USB 3 Gen 2 Hub - Try direct USB 2.0 ??

There are 4xthunderbolt 4 ports, 2x USBC ports, and 2 USB A ports on my mac, ive tried to connect to each one of them directly, through adapters and through powered usb hubs to no avail.

Im wondering if I should try some other USB A hub.

Also I put a breakpoint in the code and the reason the properties are greyed out is

Could the property ids change?

What's even more interesting is that I've tried CameraController and it can change camera properties while OpenPNP has these settings greyed out.

I guess @vonnieda or others would have to help here. Jason mentioned that native M1 support is not yet there, and I guess the restrictions come from there. The web cam drivers probably being somehow "proxied" by "virtual drivers" inside the Rosetta 2 abstraction.

Unfortunately, I know almost nothing about the native code and JNI side of OpenPnP, and Mac OS X, M1, Rosetta 2 etc.

Thanks for the hint - ill try to run openpnp with java 17 that can run naively on m1

Like I said, my knowledge is limited, but I think changing the Java version is not enough, because underneath the  OpenPnpCaptureCameras  there is the OpenPnP Capture library, which is a piece of C/C++ software, that is bound via JNI to Java. It is still currently packaged as X86 code, and it will tie into the OS X webcam driver using X86 API. My admittedly wild guess is that this API is only a limited-functionality proxy to the real native M1 webcam driver API.

A similar thing is true for all the OpenCv code, which is highly optimized, which I guess does not translate all that well with Rosetta 2. Don't expect best performance.

I hope somebody knowledgeable in these matters can port these native libs over.

Ok - it wasn't M1 related issue. It was the issue with openpnp-capture not working correctly on macOS 12

Luckily - the fix has been implemented a while ago (PR) but newer version wasn't plugged in.

I created a PR to bump openpnp-capture in openpnp-capture-java. If approved will bump in openpnp as well. PR
