Workaround is to hardcode the webcam name like this

WebCamSource(web_cam_format="dshow", web_cam_id="video=HD WebCam", options={'framerate': '10'})

Device names can be listed using ffmpeg via (see http://4youngpadawans.com/stream-camera-video-and-audio-with-ffmpeg/)

ffmpeg -list_devices true -f dshow -i dummy

Solution

• Extend webcam by a function that lists the available devices (for any OS).
• Enforce that developers to select one of these devices -> WebcamSource constructor takes one entry of this list as input.
• Developers should still be able to provide additional options like the framerate.

It seems we need to add a C++ extension that reads the device names for Windows;

In the future, we should consider to unify all video sources. Basically, all use the pyav backend... so we could have a basic pyav video source. Inheriting from this one, we can have a video file source, a webcam source, screen capture source, and maybe web streaming sources.
