Select the running application, add Breakpoints to the source code and debug/step along. To do this, start the terminal executable, then go to Xcode -> Debug -> Attach to Process. You can totally do frame by frame debugging, using the camera (as long as the program compiles to a functional executable.) Now this is pretty cool, and gets me to 98% functionality. you can attach the debugger to a running (terminal) process.
How do you guys do frame by frame analysis? This is the only way I know of that will at least partially work.
If you really want to do some video / camera debugging, you do have the option to "pre-record" a video, then open that video in your development environment. The app opens in the terminal window and works just fine as noted by SSteve. Obviously you build the executable in your development tool (in my case Xcode) then open the executable from the projects Build/Debug folder. You have to ensure permissions for the Terminal are set in Security and Privacy per photo above. Yes, you can run an OpenCV project on MacOS WITH your camera after the program has been successfully compiled to Unix Executable. I sure would like to be able to step thru code to understand frame by frame possible design issues. Why does Apple allow us to access the camera via terminal but not in Xcode? What's the logic there? Adding the NSCameraUsageDescription key/value was a total bust. Copy ist save it elsewhere, modify it via Xcode, resubmit.) Note: Don't try this without keeping a copy of the original ist. How does that even work? I did do a whole lot of testing, including researching modifying the ist for the Xcode application package (Finder -> Applications Folder -> Xcode -> Rt click, Show Package Contents. When I click over to Microphone, I see different apps listed, INCLUDING Xcode. In my case this shows two applications which require additional permissions to get access to the camera, Terminal and Virtualbox (not sure what happens to browser, Facetime?) I do note, Xcode didn't make this list.

If I go to Mac Apple Icon (Upper Left Corner) -> Systems Preferences -> Security and Privacy I can glean a lot of info. As others have noted, MacOS security / permissions issue. With a bit more testing I think it's something else. My initial thought was that this was an OpenCV issue. I know those words originate from the OpenCV library here. Stream or file Program ended with exit code: 255 OpenCV: camera failed to properly initialize! Error opening video OpenCV: not authorized to capture video (status 0), requesting. The error I'm seeing when trying to run OpenCV from my MacOS development environment Is: So at the moment I can't use CodeRunner to run a c++ program that accesses the camera.
#Opencv for mac how to
Once I granted that, the c++ program was able to access the camera when run from Terminal.Īs far as CodeRunner, I'm not sure how to get CodeRunner to run Python programs under a virtual environment so I haven't been able to run a Python OpenCV program to get it to ask for camera access. Running that program from Terminal resulted in Terminal asking for camera access. I took the advice of in the comments to give it a try with Python. The problem was that the c++ program, for whatever reason, wasn't requesting camera access. Then give camera permission through the pop out that will appear.

Then your openCv c++ program will gain the access to the FaceTime HD Camera afterwards.įor example, you can install ImageSnap by: Tags:, Categories: Updated: AugShare on.It not an ultimate solution but I got it resolved by installing any terminal application that request access to your Camera.

An example of this is setting up a Python OpenCV algorithm on a Raspberry Pi 2/3/3+, then inserting the same SD card into a Raspberry Pi 0/0W/1 will require reinstalling OpenCV–this is trivial and fast to do. With Raspbian), you will need to pip uninstall and pip install upon inserting the SD card into an ARMv6 system, or SIGILL Illegal Instruction error will result.
