DCAM1394相机Linux下的驱动源码

Mon Jan 17 10:53:15 2000   <[e-mail]>

	* Made constants in dc1394_control.c explicitly ULL, UL, or U

Mon Jan 17 14:04:46 2000   <[e-mail]>

	* Put underscore in front of #ifdef in dc1394_control.h for convention
	* Added extern "C" to dc1394_control.h for C++ support

Wed Jan 19 18:30:49 2000   <[e-mail]>

	* Converted values in dc1394_control.c to compensate for conversion
	  from little endian to big endian when transferred over 1394 bus.

Thu Jan 20 16:04:24 2000   <[e-mail]>

	* Implemented conditional code for big endian/little endian machines
	  and changed autoconfig script to test for endianness.  Added file
	  src/config.h.in to define WORDS_BIGENDIAN.

Wed Jan 26 20:03:28 2000   <[e-mail]>

	* Fixed bug with #ifdef being using instead of #if for testing if
	  !WORDS_BIGENDIAN

Tue Feb  1 16:09:24 2000   <[e-mail]>

	* Added tons of new functionality for querying and setting features
	  on the camera.

Tue Feb  1 18:19:52 2000   <[e-mail]>

	* Removed test pattern code since that is not part of the
	  1394-based Digital Camera spec.  It's specific to my TI camera.

Wed Feb  2 14:11:14 2000   <[e-mail]>

	* Fixed a bunch of bugs regarding the return value of raw1394_read()
	  (ie. it's >= 0 on no error, < 0 on error)

Fri Feb  4 11:03:42 2000   <[e-mail]>

	* Added more convenience functions and new functions to set auto mode,
	  turn features on/off, use one push auto mode, and read min/max values
	  for features
	* Fixed bug in reading the min value of a feature
	* Fixed major bug in version 0.2 with setting the value of a feature
	  (caused all other feature attributes to be cleared in the process)

Mon Mar 13 15:41:17 2000   <[e-mail]>

	* Incorporated changes suggested by Per Dalgas Jakobsen.  This
	  effectively removes all the endian dependent code (much cleaner).

Mon Mar 13 18:28:49 2000   <[e-mail]>

	* Incorporated more changes suggested by Per Dalgas Jakobsen to
	  further clean up the code.  Structured the rest of the code to
	  be uniform with these changes.
	* Changed the names of dc1394_get_current_value() and
	  dc1394_set_current_value() to dc1394_get_feature_value() and
	  dc1394_set_feature_value() (breaking compatibility with old library)
	* Added target_temperature parameter to dc1394_get_temperature()
	  (again breaking compatibility with old library)

Mon Oct 16 2000 <[e-mail]>
	* Changed return values of external functions so that they return
	DC1394_SUCCESS or DC1394_FAILURE instead of returning the subsystem
	retval (allowing checks such as if (dc1394_call()<0) {error handle}
	(breaks compatability with old library)
	* Added routines to nicely handle setting up multiple cameras to 
	capture frames simultaneously
	* Added routines and structures that represent the entire feature set 
	of a camera, and can interrogate a camera to get the feature set in a
	somewhat optimized way
	* Added routines that return cameras nodes described by their unique ID
	* Fixed dc1394_get_camera_info 
	* functions added are:
	dc1394_get_camera_feature_set
	dc1394_get_caemra_feature
	dc1394_print_feature
	dc1394_print_feature_set
	dc1394_create_handle
	dc1394_get_camera_nodes
	dc1394_get_sorted_camera_nodes
	dc1394_print_camera_info
	dc1394_setup_camera
	dc1394_release_camera
	dc1394_multi_capture
	* structures added are:
	dc1394_cameracapture 
	dc1394_feature_info
	dc1394_feature_set

Thu Feb  1 02:39:22 2000   <[e-mail]>

	* Updated to use new version of libraw1394
	* Changed error handling to use new libraw1394 error handling
	* Code beautification

Tue Feb  6 03:19:07 2001   <[e-mail]>

	* Added libraw1394 version detection to configuration process
	* Added compile options for different versions of libraw1394

	* Made all enumerations mutually exclusive by 32 rather that 16
	* Fixed code which broke due to enumeration change
	* Added macros for feature to offset querying in dc1394_control.c
	* Added backwards compatibility to Format 7 register access code

Thu Apr 12 12:52:30 2001   <[e-mail]>

	* Fixed dc1394_get/set_video_mode/format/framerate to work with new
	  enumerations.
	* Fixed FEATURE_TO_VALUE/INQUIRY_OFFSET macros to work for both
	  FEATURE_HI and FEATURE_LO queries.
	* Exposed dc1394_feature_desc (feature description array).
	* Created dc1394_internal.h for definitions internal to the library
	* Moved some definitions from dc1394_control.h to dc1394_internal.h

	* Fixed feature counting for loops in dc1394_control.c (Dan Dennedy)
	* Fixed get/set_trigger_mode functions in dc1394_control.c to work with
	  new enumerations (Damien Douxchamps)

Mon Apr 30 12:46:22 2001   <[e-mail]>

	* Fixed problem with dc1394_get_camera_feature() failing due to feature
	  id being modified by feature to offset macros (fix by Li Ming)

Thu Jun  7 12:29:26 2001   <[e-mail]>

	* Applied Dan Dennedy's patch which fixes image capture with newest
	  version of libraw1394 (0.9) and fixes a small spelling mistake

Tue Jul  3 16:33:50 2001   <[e-mail]>

	* Added functions to control the trigger feature:
	     -dc1394_set_trigger_on_off()
	     -dc1394_get_trigger_on_off()
	  (addition by Audun Jan Myrhol <[e-mail]>)

Sat Sept 08 02:19:48 2001 <[e-mail]>

    * Updated kernel-video1394.h against current CVS version
    
Mon Sept 24 22:36:12 2001 <[e-mail]>
	* moved src -> libdc1394
	* included examples subdir in autoconf and automake
	* added examples/Makefile.am
	* examples build, but do not automatically install 

---- v0.8.3 released -------------------------------------------------

Fri Nov 23 15:48:00 2001 <[e-mail]>
	* use dc1394 feature-indexed function in
	  dc1394_(get/set)_trigger_on_off
	  
Thu Jan 31 23:38:28 2002 <[e-mail]>
    * dc1394_control.h: added dma_device_member to struct 
      dc1394_cameracapture. This enables support for mutliple
      host adapters as well as the new video1394 devfs names.
    * dc1394_capture.c: _dc1394_dma_basic_setup() uses 
      above struct member to open video1394 device. If the
      char pointer is null, then it defaults to "/dev/video1394"
      for backwards compatibility.
    * kernel-video1394.h: synchronize with video1394.h changes made
      Oct 21 and included in kernel 2.4.17!!

Fri Mar 15 14:43:31 2002 <[e-mail]> 
	* dc1394_control.h: updated format7 functions
	* dc1394_format7.c: updated dc1394_query_format7_color_coding_id
	  so that it now returns a valid COLOR_FORMAT7_X value.

Mon Mar 18 14:43:31 2002 <[e-mail]> 
	* dc1394_control.c: fixed bug in dc1394_set_feature_on_off: it
	would only set 'on' if the feature was 'off', no matter what
	was the argument.
	* dc1394_control.c: fixed quadlet-per-packet for format_0, mode_4,
	15fps (was 280, should have been 480)

Mon March 26 0:41:50 2002 <[e-mail]>
    * Applied David Moore's <[e-mail]> patch to avoid getting
      old captures with dma_multi_capture.
    * Applied John Stanley's <[e-mail]> patch to use multiple
      cameras on mutliple ports (hosts).
      NOTE: the new dc1394_destroy_handle() in dc1394_control.h
      NOTE: the dma device file defaults to the video1394 devfs default
      naming convention when not specified: /dev/video1394/<port>

Fri May 10 16:12:00 2002 <[e-mail]>
    * dc1394_capture.c, dc1394_control.h:
      bugfixes in dc1394_cameracapture, dc1394_dma_multi_capture(),
      and _dc1394_dma_basic_setup() to better support grabbing all
      frames.
    * dc1394_capture.c: dc1394_dma_setup_capture() modified to take
      dma_device_file as a param to force users to set it.
      
Sun July 21 22:51:00 2002 <[e-mail]>
    * added examples/dc1394_multiview.c to test/demonstrate multicapture
      over multiple ports.
	  
Fri July 28 00:26:00 2002 <[e-mail]>
    * dc1394_capture.c: added drop_frames boolean to
      dc1394_dma_setup_capture().
    * bumped versions to 0.9 since interface has changed some.
      Correct libtool versions:
	    major=9, interface changed
		revision=0, first implementation of this interface
	    age=0 for no backwards compatibilty
    * examples/dc1394_multicapture: added drop_frames support, cleanup.

Wed Aug  7 17:08:31 2002 <[e-mail]>
    * added several format7 functions for IIDC 1.30 compatibility.
    * first quick hack of IIDC 1.30 handshaking for byte-per-packet
      setting in format7. This happens in _dc1394_basic_format7_setup.

Tue Aug 20 10:40:12 2002 <[e-mail]>
    * added support for Point Grey cameras, which support IIDC with
      a little tweak (modifications in dc1394_is_camera).

Thu Aug 22 10:10:00 2002 <[e-mail]>
    * Updated support for PointGrey cameras (added the 0x800002
      software revision code)
