It is a great tutorial. Thanks, I'm creating the Live Streaming Video. It's storing in .avi format. When i'm playing the Video. I'm not getting the audio of that video. I hope that opencv does not provide the audio features. Kindly let me know if you have any idea.

I have a webcam that can capture 16 MP still images but the resulting captured image is blurry or at least it looks like it was taken at a smaller megapixel. How can I fix this?
Hi,I recently discovered opencv. I'm trying now to take a photo by using a webcam. However, the problem is that the photo taken is always black and its size is of 6kb. I don't know how to solve the problem. Please help me. By the way, the video was really interesting. Thank you very much. P.D: This is my source code
A few questions. First, this requires OpenCV. I downloaded it and extracted the files. Do you have any videos on the proper setup of OpenCV under Win 10 64 bit? Also, what would the code be to do a simple task like activate the webcam, wait until a face is detected, save the image as a file, then exit. Another thing, I have py2exe. Would I be able to turn the project into an exe without needing to install OpenCV on the computer where this is deployed, or are those files added into the project?

Thanks for the Tutorial. Improvement would be that we can download or copy paste the script. It´s hard to read
thanks, sir love this tutorial
Excuse me sir! How did you you stop the video capturing. I'm not able to do that.
thank you very much for this wonderful tutorial… ????
thank you

The way you explain it is so clear. Thanks
