- Changes since last version:
-
- 1.1
- o Fixed -dither color option to find best 24 bit or greater visual
- for most machines.
- o Fixed recursive loop in Makefile.
- o Added entries for R6000 and SGI's in Makefile
- o Fixed declaration of j_rev_dct.
- o Does initial sequence start code check to confirm validity of mpeg stream.
- o Changed or's in ordered dither to add's to allow more flexible
- allocation of color ranges.
- o Uses shared memory.
- o Lots of little bugs fixed.
-
- 1.2
- o Fixed shared memory problem (freeing memory twice on exit).
- o Added entries for Sony NEWS machines
- o Added monochrome support.
- o Unrolled loops for optimization.
- o Variety of small bugs.
-
- 2.0
- o Added ability to use private colormap.
- o Display name can now be given as part of command line.
- o Fixed green artifacts problem
- o Fixed sequence end code cutoff problem.
- o Lots of performance tweaks.
- o Other bugs.
-
- 2.1 (newest version)
- o Fixed frame dropping problem.
- o Supports MPEG system layer (tosses audio)
- o 16, 32 bit color modes (thanks to: Erik Corry erik@kroete2.freinet.de)
- o Added -owncm to guarantee a private colormap
- o Added gray256 to get 256 shades of grey (and added gray/grey no diff)
- o Fixed leaving of shared memory buffers when shared memory crashes
- (in the common case of running from the wrong display)
- o Instructions for IRIX4 Cflags in PLATFORMS.
- o Added -step, -start, and -end
- o Fixed insanely subtle readfile bug
- o Added color2 true color doubling dither, provided by garyo@avs.com (thanks!)
- o Added ppm dither, provided by Jef Poskanzer <jef@acme.com> (thanks!)
- o Added bzero.c for silly SOLARIS
- o -no_display doesnt put up a window now.
- o -gamma float, raises the luminance of each pixel to float (a
- floating point number), thus -gamma 0.8 darkens, -gamma 1.2 lightens
- o Fixed ycc to rgb conversion block assignment mixup.
- (thanks to John Toebes <toebes@unx.sas.com> for pointing this out)
- o Added frame rate limiting (-framerate)
- o Doesn't skip initial B frames (after an I) if the GOP is closed.
- o Auto-determines RGB order of server (well, RGB vs BGR anyway).
- o Fixed a few grainy blocks appearing due to bugs in sparse IDCT function.
- o -nop now implies -nob (doesnt make sense to have B's w/o P's)
- o -seek indexes into files
- o Added chroma averaging in color and color2 dithers (thanks to
- tristan@tcela.la.tce.com (Tristan 'RAMBO' Savatier))
- o Added -quality option, which, when turned on,
- o correctly implements halfpel motion vector averaging
- o uses a very time-consuming but accurate IDCT
- o Sped up player a little by using lookup tables for y/cr/cb values
- o Minor, unreported bugs.
