Comment (by domingo):

 ffmpeg just reports media types returned by webcam driver, which seems to
 output static tables. However webcam driver checks resolution and
 framerate upon connection and rejects unsupported ones. Anyway it is
 webcam software issue, not ffmpeg.

 Btw, regarding resolution - pay attention on framerate. 1920x1080 is not
 supported at full 30 fps framerate. And again, webcam driver behaviour
 could heavily depend on AUTOFOCUS setting. Typically resolutions get
 restricted when autofocus is enabled.
