Thu Sep 03 10:45:00 2002 <[e-mail]>
    * Bugfix in v1.30 format7 capture handshake. Thanks to Yasutoshi Onishi
      for pointing it out.

Thu Sep 09 12:00:00 2002 <[e-mail]>
    * more v1.30 handshake update

Fri Sep 10 11 12:00:00 2002 <[e-mail]>
    * even more v1.30 handshake update (now with proper error handling)

Sun Sep 22 17:30:00 2002 <[e-mail]>
    * added absolute feature setting functions. This is a first hack. 

Mon Sep 23 10:10:00 2002 <[e-mail]>
    * debugged absolute settings. Tested for shutter without problems.

Fri Sep 27 13:00:00 2002 <[e-mail]>
    * more v1.30 handshake update to handle backward compatibility
      with v1.20

Tue Oct 22 15:10:00 2002 <[e-mail]>
    * applied Christophe Achard patch, with some modifications.

Thu Oct 22 15:10:00 2002 <[e-mail]>
    * added "dc1394bool_t abs_control" to "dc1394_feature_info" struct
    * fixed, cleaned-up and finalized the absolute control code

Fri Oct 23 17:19:00 2002 <[e-mail]>
    * fixed missing <<16 shift in dc394_get_format7_unit_position

Sun Oct 27 00:13:00 2002 <[e-mail]>
    * added examples/dc1394_vloopback.c to demonstrate how to make
      digital camera format0 a Video4Linux source.

Mon Nov 18 10:15:23 2002 <[e-mail]>
    * we now use packet_per_frame correctly for format7. This should
      fix 'walking' frames in DMA mode.
	
Mon Nov 20 10:35:00 2002 <[e-mail]>
    * Use a little trick from Martin Gramatke to avoid misinterpreta-
      tion of TOTAL_BYTES registers. We don't use the latter register
      anymore.
	
Wed Jul 2 14:35:00 2003 <[e-mail]>
    * fixed some F7 issues. Thanks to Kero van Gelder.
    * changed total_bytes to unsigned long long int in
      dc1394_query_format7_total_bytes.

Wed Jul 30 09:32:01 CEST 2003 <[e-mail]>
    * fixed bytes_per_packet setting in _dc1394_basic_format7_setup
    * cancelled the previous commit (18/7/2003): it was a mistake.

2003-08-12  Dan Dennedy <[e-mail]>
   * dc1394_control.c: make config ROM reading more generic,
     remove tab indenting to make consistent
   * configure.in: incrmement lib revision

2003-08-13 Damien <[e-mail]>
	* dc1394_control.c: cleanup config ROM code; fix for Point
	        Grey cameras

2003-08-20  Dan Dennedy <[e-mail]>
    * use command register base from config rom offset instead of hardcoded
    * make raw1394 userdata point to a new dc1394_camerahandle struct 
      containing port, software version, and command register base


2003-08-28 Damien <[e-mail]>
    * fixed feature detection: we now use both 0x404 and 0x5XX registers in
      dc1394_is_feature_present. dc1394_query_feature_control is deprecated
      and has been commented out. 

2003-09-02  Dan Dennedy <[e-mail]>
    * examples/*.c: call dc1394_destroy_handle() to cleanup mem and show
      proper technique
    * examples/dc1394_multiview.c: show new proper technique of multi-capture by
      creating a handle for each camera as opposed to port.
    * examples/gray_color_image.c: new example similar to grab_gray_image, but
      also contains example code how to locate first camera on any port and 
      attempt to make the camera non-root.

2003-09-15 Damien <[e-mail]>
    * fixed format7 capture setting when the current size register is initialized
      to zero at the camera boot.
	  
2003-09-02  Dan Dennedy <[e-mail]>
    * examples/grab_color_image.c: remove auto settings, add --guid option, add
      filename argument.
    * examples/dc1394_vloopback.c: add scaling, set default mode to mmap, add 
      mmap double buffering, add pipe mode option, adjust palette by option
      (pipe) or by ioctl, lookup default v4l device name via procfs, daemon
      option.

2003-09-23  Dan Dennedy <[e-mail]>
   * examples/grab_color_image.c: fix locating cam by guid on any port
   * examples/dc1394_vloopback.c: add --guid option like grab_color_image
     and renamed some options, and added root detection and reset
	
2003-11-15 Damien <[e-mail]>
    * fixes/additions by Johann Schoonees:
    * fixed format7 capture setup function missing some parameters 
    * fixed compil warning in dc1394_absolute.c, line 261.
    * fixed harmless but misleading bug in dc1394_format7.c: line 802 should be removed.
    * add functions dc1394_get_one_shot and dc1394_get_multi_shot.
    * changed dc1394_get_camera_misc_info to avoid probing memory psec registers
      if no user memory is available. This is necessary for the iSight camera from Apple,
      which does not implement registers 0x618h thru 0x62Ch.
	
2003-12-04 Damien <[e-mail]>
    * little tag commit for version 0.9.2
	
2003-12-15 Damien <[e-mail]>
    * fixed significant bug regarding IIDC specs revision detection
      (in dc1394_get_sw_revision).
	
2003-12-17 Damien <[e-mail]>
    * temporary fix for bpp settings in dc1394_format7_basic_setup
	
2003-12-24 Damien <[e-mail]>
    * updated the IOCTLs for kernels 2.4.21+ and 2.6.0+. This breaks compatibility with
      previous kernel versions.

2004-01-04 Dan Dennedy <[e-mail]>
    * simplify video1394 includes and correct Damien's ChangLog entry about kernel 2.4
      compatibility.
    * examples/dc1394_vloopback.c: minor bugfixes.
    * autogen.sh: add missing libtoolize.
	
2004-01-14 Damien <[e-mail]>
    * fixed a bug related to IIDC version in format7 functions. All registers specific 
      of v1.30 are now only probed if the version is 1.30.

2004-01-14 Dan Dennedy <[e-mail]>
    * libdc1394/ieee1394-ioctl.h: removed unnecessary
    * examples/dc1394_vloopback: added support for palettes yuv422p and yuv420p,
      added support for scaling up to 1024x768, greater v4l application compatibility.

2004-01-15 Damien <[e-mail]>
    * little additional fix regarding F7 and version issues.
	
2004-01-17 Damien <[e-mail]>
    * f7 csr caching by T.Evers

2004-01-19 Dan Dennedy <[e-mail]>

    * updated examples to call dc1394_free_camera_nodes
    * examples/dc1394_vloopback.c: workaround potential linux/videodev.h
      problems on some distros' kernel headers.

2004-01-20 Dan Dennedy <[e-mail]>
    * dc1394_multiview.c: bugfix segfault
	
2004-01-21 Damien <[e-mail]>
    * print a warning when format7 BPP is zero.
	
2004-01-26 Damien <[e-mail]>
    * version is now properly memorized. This caused several problems
      with format_7 cameras.
	
2004-01-28 Damien <[e-mail]>
    * added a polling policy to the DMA capture functions using the
      patch from Tim Evers.
    * by popular request, the direct register manipulation functions
      GetCameraControlRegister and SetCameraControlRegister are now
      accessible.

2004-01-29 Tim Evers <[e-mail]>
    * libdc1394/dc1394_capture.c (_dc1394_dma_multi_capture_private):
      in Poll-mode return DC1394_NO_FRAME not FAILURE

2004-01-31 Damien <[e-mail]>

    * simplify FEATURE_TRIGGER check in dc1394_get_camera_feature
    * added printf warning before return in dc1394_print_feature
    * replaced '== DC1394_FAILURE' by '!= DC1394_SUCCESS'
    * removed FORMAT_STILL_IMAGE definition to 390, it messes up with the
      number of available formats
    * replaced a 0x1<<31 by ON_VALUE

2004-02-04 Damien <[e-mail]>
    * apply patches from Tim Evers and Johann Schoonees

    * fixed trigger polarity bug
    * fixed default format7 csr value bug (was "-1" instead of the new "0")
    * revert FORMAT_STILL_IMAGE change.
	
2004-02-06 Kristoffer Delforge <[e-mail]>
    * use FEATURE_TO_ABS_VALUE_OFFSET in QueryAbsoluteCSROffset
    * check that mode id is within boundaries in GetCameraFormat7Register
      and SetCameraFormat7Register
    * moved declarations to beginning of the function

    * removed unnecessary 'else's.
	
2004-02-10 Kristoffer Delforge <[e-mail]>

      are default to QUERY_FROM_CAMERA, as in dc1394_setup_capture

      dc1394_capture.c
    * moved declarations to the beginning of functions.

2004-02-20 Kristoffer Delforge <[e-mail]>
    * changed a >= to > in dc1394_capture.c:99
    * changed a >= to = in dc1394_capture.c:112

2004-02-20 Damien <[e-mail]>
    * applied patch from Johann Schoonees for extra buffering option.
      This breaks compatibility for the capture functions. Examples have
      been updated.
	
2004-04-07 Damien <[e-mail]>

      with weird hardware.
