Motion JPEG编解码器源代码

2001-08-29  Kawamata/Hitoshi  <[e-mail]>

	* README.2-3pulldown: added.

2001-08-28  Kawamata/Hitoshi  <[e-mail]>

	* timecode.c, timecode.h: moved to ../utils/mpegtimecode.[ch].
	* yuvkineco.c: use mpegtimecode.h.
	* all: add copyright(GPL) comment, use config.h, use mjpeg_logging.h.

2001-08-02  Kawamata/Hitoshi  <[e-mail]>

	* yuvycsnoise: chroma noise detection case increased.

2001-07-31  Kawamata/Hitoshi  <[e-mail]>

	* yuvycsnoise: reduce noise detection miss.
	  Chroma noise reduction added.
	  New luma noise reduction method 'triframe' added.
	  Methods called 'interfield', 'intrafield' are
	  now called 'biframe', 'infield'.
	  Some options changed.
	  Options(new/changed):
	    -m tbi: Select method (default: tbic).
	       t: 'triframe' method.
	       b: 'biframe'  method (replace old option '-x').
	       i: 'infield'  method (replace old option '-i').
	       c: chroma noise reduction.
	    -S min:
	    -T errt,maxt:
	    -B errb,maxb:
	    -I erri,maxi:
	    -C errc,maxc:
	       error and max difference of each method.

2001-07-29  Kawamata/Hitoshi  <[e-mail]>

	* timecode.c: Name of environment variable fixed.
	  To use drop frame timecode, set MJPEG_DROP_FRAME_TIME_CODE=1.

2001-07-28  Kawamata/Hitoshi  <[e-mail]>

	* yuvkineco: Always drop frame#0 fixed.
	  Now frame#0 will always output.
	* yuvycsnoise: Abort at last frame fixed.

2001-07-27  Kawamata/Hitoshi  <[e-mail]>

	* yuvycsnoise: Almost rewrote.
	  Options:
	    -t: test (unchanged).
	    -i: disable 'intrafield' method.
	    -x: disable 'interfield' method.
	    -S min,maxi,maxx: threshold of luma difference is noise or not.
	       min:  minimum (unchagend).
	       maxi: maximum in 'intrafiled' method.
	       maxx: maximum in 'interfiled' method.
	* yuvkineco: Bug when -N CycleList and InputFPSCODE < 4 fixed.

2001-07-24  Kawamata/Hitoshi  <[e-mail]>

	* addtask.c: Wrong parent after initialize task fixed.
	* putframe.c: remove cast which need not.

2001-07-23  Kawamata/Hitoshi  <[e-mail]>

	* addtask.c: Wrong parent of initializing task fixed.
	* timecode.h: Added. Separated from yuvfilters.h.
	* all: Names of types and functions changed and clarified.
	  files renamed:
	    addfilter.c -> addtask.c
	    allochandle.c -> alloctask.c

2001-07-22  Kawamata/Hitoshi  <[e-mail]>

	* allochandle.c: Added.
	* all filters: replace malloc()/free() with allochandle()/freehandle().
	* main.c: Now chained filter can be used.
	* addfilter.c: Added.
	* yuvycsnoise.c: Added.
	* yuvkineco.c: New option -S to insert filter yuvycsnoise.
	* yuvtemplate.c: Added.

2001-07-20  Kawamata/Hitoshi  <[e-mail]>

	* main.c: Pass argv[0] to filter.
	  (OLD: pass argv+1 to filter as argv)
	* all filters: Skip argv[0]
	* timecode.c: Added.
	  mpeg_timecode() supports NTSC drop frame timecode.
	  To use drop frame timecode, set environment variable:
	    MJPEG_DROP_FRAME_TIME_CODE=1
	* yuvctrlbytty: Use mpeg_timecode().
	* yuvkineco: Use mpeg_timecode().
	* yuvkineco: Add cycle list read / write.
	  Command line arguments completely changed.
	* TODO: Added.

2001-07-17  Kawamata/Hitoshi  <[e-mail]>

	* GNUmakefile: Deleted.
	* Makefile.am: Added.
	  Automake only do about install and dist.
	  Building binaries almost done by GNU make.

2001-07-12  Kawamata/Hitoshi  <[e-mail]>

	* yuvkineco: Fix U,V merge when interlaced.
