    Revision:

2004-04-14 19:45:23 GMT	                                	patch-14

    Summary:
      Fixed small bug in trellis code.
    Revision:
      xvidcore--stable--1.0--patch-14

    From ed.gomez (spotted by jean marc):
     * Trellis optimization was computing the sum |coeffs| wrongly
       because the Compute_sum function wasn't doing zigzag scanning
       and stopped at last non zero coeffs in linear scanning...
       The trivial fix could have been to pass the zigzag to the compute
       sum function so it could have done its job right.
       But... Why computing stuff that is already known in the upper layer ?
       I removed the compute sum function, and just pass the original sum
       value in trellis function parameters, just in case we have to return
       it again because trellis failed optimizing the block coeffs.
    
       This fix the bug and saves cycles :-) (but should not be noticeable)

2004-04-12 12:06:12 GMT	                                	patch-13

    Summary:
      Don't do SAD and RD based searches for qp.
    Revision:
      xvidcore--stable--1.0--patch-13

    From sysKin:
     * MakeGoodFlags function wasn't disabling SAD based search when
       using RD. This was causing slowdown for no gain at all. This
       patch should speed up encoding in qp mode.

2004-04-12 12:01:19 GMT	                                	patch-12

    Summary:
      3dnow functions proper separation.
    Revision:
      xvidcore--stable--1.0--patch-12

    From pete (thx to a forum report):
     * Separate correctly pure 3dnow functions and 3dnow+mmxext functions.
       This fix "Illegal instruction" crash on old k6-2 CPUs.

2004-04-12 11:57:20 GMT	                                	patch-11

    Summary:
      Better MV clipping code.
    Revision:
      xvidcore--stable--1.0--patch-11

    From sysKin:
     * Better MV clipping. DivX 5 generates out of range vectors and clipping
       them directly borks the decoding of other MVs for which out of range
       MVs were predictors. So it's just better to clip them for the block
       decoding and keep an unclipped version for predictions.

    Summary:
      PGM support back in xvid_decraw.
    Revision:
      xvidcore--stable--1.0--patch-10

    From ed.gomez:
     * pgm/pnm format added back to xvid_decraw
       + pgm/pnm formats are now default for yv12/i420/rgb24 pixel format.
       + tga is default for rgb16/32
       + use option -f to choose tga, or pnm/pgm

2004-04-07 22:30:15 GMT	                                	patch-9

    Summary:
      3DNow Ext functions use MMXEXT opcodes.
    Revision:
      xvidcore--stable--1.0--patch-9

    From Soltius (XviD Forum):
     * Most of 3dnow extension functions do use MMXEXT opcodes, so
       classify these functions as 3dnowext+mmxext. Avoids K6-2
       boxes to crash with an invalid instruction error reported
       by the host OS.

    Summary:
      RGB 16bit output fix.
    Revision:
      xvidcore--stable--1.0--patch-8

    From ScarletteTout (XviD Forum):
     * Fix RGB 16bit output in C functions.
    
    From ed.gomez:
     * Replaced PGM output by TGA output so it's easy to implement
       RGB 16/24/32 and greyscale bitmaps support in a single format.
       (pgm could have supported RGB 24 and Greyscale only)
     * Added colorspace choice to xvid_decraw
       Use option -c csp, where csp is either rgb16, rgb24, rgb32, yv12 or i420
       Defaults to i420.

    Summary:
      VFW Resource leak fix (try #2)
    Revision:
      xvidcore--stable--1.0--patch-1

    From Suiryc on IRC:
     * both encoder and decoder ending functions were calling
       the dll freeing code. This was an error as the first function
       called would unbind core function for the second called one.
       Thus xvidcore could not release buffers.

    Revision:

    From sysKin:
     * Storing ressources in global vars is making multithreaded/instanced
       apps leaking lot of memory. Moved these vars to codec struct.
