Hi, (my first contact to this list) with luvcview I have a nice video stream. When I started cheese, I saw a picture, but not stream: ~$ cheese -v Cheese 2.28.0.1 ** (process:8217): WARNING **: Couldn't change nice value of process. ** (process:8220): WARNING **: Couldn't change nice value of process.

Afterwards I could start luvcview: ~$ luvcview luvcview 0.2.6 SDL information: Video driver: x11 A window manager is available Device information: Device path: /dev/video0 Stream settings: Frame format: MJPG Frame size: 640x480 Frame rate: 30 fps and the video is still ok. What ist nessecary to get cheese running properly. Any help appreciated! Thanks a lot! Bernhard -- Bernhard Kleine <bernhard kleine gmx net>
