Re: flicker/jumpy at the bottom of the video
Hi, one of the sensors managed by the gspca_gl860 has some weird resolutions : 800 x 598 and 1600 x 1198. To set these resolutions to 800 x 600 and 1600 x 1200 causes a flickering effect because of both missing lines of data from the sensor. Thus a stupid question, does the resolutions are these chip are well known ? O.
