video_capture | Cross platform Video Capture library | Video Utils library

I made face recognition app using face_recognition and OpenCV libraries but i want to break the while loop 10 seconds after executed the script. I can't use OpenCV's waitKey(10000) because of the low fps. How can i achieve this? Thank you.

While loop is;

I am trying to decode several video streams using GStreamer and Python. Here's my code:

So I am trying to make a code where when face is detected from webcam it shows a green square around face. That part is done. What I want to make next is that when face is no longer detected by program that it break the loop and exit program. I tried ways through "if" or "else" or find something online but I was not going anywhere. Is there some way to do it? Here is my code:

Good day everyone I'm sorry I'm new to python programming sorry if I'm asking this even this is basic or not. Someone can help me with this? The problem is I want to put the data that has been read by my Pyserial from my Arduino temperature sensor but I don't know how.

Here code for the Temperature to pyserial:

I'm trying to make a Video Player, that uses gesture recognition for the video player actions (play, pause, fast-forward, etc.)

For the Video Player I use PyQt5, and for the gesture recognition I use MediaPipe. Here's what my program looks like

Now this is the code I use for running the Camera and emiting it in the QMainWindow:

How do I leave the webcam open and do the face detect with haar cascade for only a few seconds?

I have a function and this function returns true if the face detect of a face has been carried out, but it must not do it immediately as soon as it detects it, rather it must do it only after the face has been detected for at least 3 seconds for example.

If I use the time module and do the wait, obviously this will simply slow down the execution of my program and consequently also that of the cv2.VideoCapture, seeing the jerky webcam.

Here is the code:

I am getting error on capturing video

java.lang.NullPointerException: Attempt to invoke virtual method 'void android.media.MediaCodec.reset()' on a null object reference

Even though i have given Record_Audio permission. I am using camerax version: 1.0.2

When I am trying to start videocapuring with opencv and python, it simply does not load. Does not show any problems, does not return anything. NOTHING!!!

The code is the simpliest one:

can you help me in solving my code problem, where I want to append the data that I have created using opencv into the csv file. I followed several tutorials on the internet, but the results were not what I wanted, here is the complete code
