[GEM-dev] PD GEM: [pix_video]: no valid video backend found

[Ramon Wilhelm]

Hello,

I've tried to film with my webcam. Unfortunately, I always receive the
error message "[pix_video]: no valid video backend found" and my webcam
only gives back an white rectangle.

Here is the full message, after loading the movement2.pd in PureData:

In the appendix is the movement2.pd program, which does not work.
I'm using the PureData Vanilla 64-bit version.

What should I do to capture a video with my webcam?
I thank you in advance.

Kind regards
