Added initialization of the "next" frame - otherwise it wait _very_ long if the camera frame number is reset ! ! Revision 1.15 2008/11/15 23:08:24 elphel ! 8.0.alpha17 - split autoexposure source file ! ! Revision 1.14 2008/11/15 07:05:38 elphel ! implemented analog gain control (in addition to gammas) while while balancing ! ! Revision 1.13 2008/11/15 03:10:13 elphel ! Some parameters renamed, reassigned. ! ! Revision 1.12 2008/11/14 07:13:32 elphel ! Added gammaReverse() and gammaDirect() functions, TODO lists, bug fixes ! ! Revision 1.11 2008/11/14 01:01:59 elphel ! cleared debug output ! ! Revision 1.10 2008/11/13 05:40:45 elphel ! 8.0.alpha16 - modified histogram storage, profiling ! ! Revision 1.9 2008/11/08 05:52:21 elphel ! debug feature ! ! Revision 1.8 2008/11/04 17:40:34 elphel ! comment typos ! ! Revision 1.7 2008/11/02 00:32:35 elphel ! added TODO ! !

Revision 1.5 2008/10/29 04:18:28 elphel ! v.8.0.alpha10 made a separate structure for global parameters (not related to particular frames in a frame queue) ! ! Revision 1.4 2008/10/28 07:05:12 elphel ! implemented white balance, HDR mode (1/1 and 2/2) ! ! Revision 1.3 2008/10/26 05:55:38 elphel ! snapshot ! !

now try to mmap

These are read from frame zero (they are not frame-related)

now open circbuf

read pointer was invalid - try the earliest frame available
