2012-11-23 15:45:18 -0600 | answered a question | Get 50% faulty pictures from webcam using VideoCapture I found another thread here which states that the implementation of how the frames are captured by openCV may be the culprit:
I am using a BeagleBoard and when using the (convenient) openCV-functions I had the mentioned problems. I tried the program Martin Fox linked in the thread, which takes YUV-frames from the webcam directly with v4l2. Now it is possible to get pictures up to 1280x1024 pixels without problems what is the resolution of the webcam's sensor. |

I just want to take single frames from a Logitech C300 webcam using openCV.
When I use the code below. Images are saved but, in about 50% of the cases they contain errors (see image So my question is, is there a way to use this mode with openCV too? I would like to avoid using v4l2 directly. |
