I have a web camera on my T500 Thinkpad. I would like to know its supported resolutions. Is there a way to find it out by means of software (and without having to consult the documentation)?
If you have video4linux installed try this:
v4l2-ctl -d /dev/video0 --list-formats-ext
Specify your camera device with -d argument, however it can be ommited if you are convinced that there's only one video device connected.
You should get something like:
ioctl: VIDIOC_ENUM_FMT
Type: Video Capture
[0]: 'JPEG' (JFIF JPEG, compressed)
Size: Discrete 320x240
Size: Discrete 640x480
