Question

I need to get a uEye camera working with python on Windows in order to take pictures and operate on the live stream.
Since uEye camer

Answer 1

I was able to get a ueye USB 3.0 camera working in Direct3D mode with the "IDS python libraries" Link to official project.

Also in use: wxpython 2.8, python 2.7. One key item to remember is to install the DirectX SDK. DXSDK_Jun10.exe worked for me.

This is working code, but it is not shutting down cleanly (it takes around 20 sec to close). It seems that just stop the capturing will allow it to close normally... an exercise for the reader.
