Ok, it might have something to do with the Microsoft Camera, I need to use in this project (build in Surface Pro Camera and also an external Microsoft HD Camera). No that was not my decision ;)
It also shows some problems in some videoplayers - is it possible that GStreamer reacts picky on some encodings?

Yes, it could be possible that the GStreamer plugins currently bundled with Processing don't support the high-res modes of these cameras. What is the highest res. you can use without errors? (unfortunately, I don't think there is much we can do from the Processing side to solve this kind of problems)

Hi,
with my Logitech C930e on Windows7 64bit I can reach:

• 800x600 at 24 fps
• 848x480 at 30 fps

The same camera reach 1920x1080 at 30 fps on Mac OSX 10.9.

You think that from gstreamer side will be a fix? Or there's an alternative to use webcam with Processing?
Thanks,

There are plans to eventually update the video library to use gstreamer 1.x (it currently relies on gstreamer 0.10 which is no longer maintained), but it will take some time for these plans to be realized.

For the time being, one possible direction could be to try to use the capture functionality built into JavaCV from Processing. Webcam capture is another project that provides camera access from Java and is actively developed.

Webcam capture unfortunately also doesn't work well with Win 8 either, had also problems with javacv in full resolution. At the moment, I think of using libvlcj. Will try to post working examples later.

This should be addressed with the latest v2 betas that use GStreamer 1.x
