Raspberry Pi Opencv 64x64 pixels
Hellom
I am currently experiencing issues with the uv4l driver on the Raspberry Pi and OpenCV.
When images are captured from the web cam, they are only 64x64 pixels. This is not the case when taking images from other applications.
Some links suggest installing OpenCV 2.4.6.1, but this has not resolved the issue.
Any advice on this issue?
First of all use OpenCV version 2.4.7, which is latest stable release and contains even more fixes. Secondly, there is the set and get parameter of the videocapture interface, look at docs. Try setting it manually to a higher rate.
Hi Steven,
Turns out 2.4.7 still leaves the issue. 2.6.1 however fixes it. Go figure.
Thank you.

But did you try to manually change it in 2.4.7? It is weird that a fix of 2.4.6.1 is skipped in 2.4.7. @Vladislav Vinogradov, @Andrey Pavlenko or @Kirill Kornyakov, any of you guys got an idea how this is possible?
Uhm and did you make a typo? Do you mean master branch or 2.4.6.1 instead of 2.6.1?
Yes. 2.4.6.1. :)
And is it possible to debug your code in 2.4.6.1 simoultaneous with 2.4.7 and see where the difference is? I am up for writing a fix if it is needed, but I need some directions of where it is going wrong.
