Subject: libv4lcontrol: fix queryctrl handling Author: Hans Verkuil <hverk...@xs4all.nl> Date: Sat May 1 13:40:59 2010 +0200 When enumerating the controls using V4L2_CTRL_FLAG_NEXT_CTRL then queryctrl should always remove V4L2_CTRL_FLAG_NEXT_CTRL when returning, even if no next control was found. So instead of using V4L2_CTRL_FLAG_NEXT_CTRL as the 'maximum' control ID libv4lcontrol.c should use V4L2_CTRL_ID_MASK instead (which is really the highest possible ID). This bug caused qv4l2 to show the user controls twice.
