Have video output open in full screen

JVond — Fri, 07 Feb 2020 10:54:52 GMT

I'd like the video output for a script to appear full screen with no manipulation upon opening. How do I modify the command to make this happen.

This is on a raspberry pi running buster.

Hi James,

To display the video output in full screen mode, Use the following commands

For C++:

cv::namedWindow("Detection results", cv::WND_PROP_FULLSCREEN);
cv::setWindowProperty("Detection results", cv::WND_PROP_FULLSCREEN, cv::WINDOW_FULLSCREEN);
cv::imshow("Detection results", frame);

For Python:

cv2.namedWindow("Detection results", cv2.WND_PROP_FULLSCREEN)
cv2.setWindowProperty("Detection results", cv2.WND_PROP_FULLSCREEN, cv2.WINDOW_FULLSCREEN)
cv2.imshow("Detection results", frame)

Hope this helps.

Where does that go for the C++ script? I can't edit it in the text editor...

Hi Vondale, James,

May I ask which C++ script are you modifying?

It could be that you need Administrator (or sudo access in Linux) to make changes to the script.

security_barrier_camera_demo.

It's not an admin issue. It shows a bunch of gibberish characters in the text editor.

I don't usually use c++ so perhaps I'm missing a required step.

Please share the path and

Please share the path and file extension of the script you are modifying. Since you are using the Raspberry Pi, the actual sample code should be under "<path-to>/open_model_zoo/demos/security_barrier_camera_demo".

Once you edit and add your changes to main.cpp, you may need to re-build the sample (under "<path-to>/open_model_zoo/demos/build" run "make security_barrier_camera_demo").

I run it from~/open_model_zoo

I run it from~/open_model_zoo/demos/build/armv7l/Release

I'll mess with the main.cpp file where you suggeted...

Your code didn't work, but I did find where the size is determined and matched it to my screen resolution. Now comes out well.

I did not find the same spot in the crossroad demo, however..

Hi Vondale, James,

Edit the main.cpp file under ~/open_model_zoo/demos/crossroad_camera_demo and include these lines code after line #817:

cv::namedWindow("Detection results", cv::WND_PROP_FULLSCREEN);
cv::setWindowProperty("Detection results", cv::WND_PROP_FULLSCREEN, cv::WINDOW_FULLSCREEN);

Don't forget to rebuilt the sample for changes to take effect, as previously mentioned, under "~/open_model_zoo/demos/build" run "make crossroad_camera_demo"). I have tested this and seems to be working fine, please give it a try.

Regards,

Luis
