[XviD-devel] Any bug left for 1.0.0 ? Then report.

Tue May 4 01:40:45 CEST 2004

Hello,

It's now time to release 1.0, so i'm gathering here the last bug reports
we could have missed during the last rc timelife. Please report any
remaining bug... the sooner the better.

Long Changelog for rc4->1.0 final. If you don't see any fix for your
specific bug, please report.

PS: some problems are left unsolved for 1.0 and already fixed in the 1.1
    branch:
      - xvid_bench compilation with MSVC (needs new project files)
      - Dering code (would have broken the feature freeze)
      - PPC port using altivec intrinsics
      - ... maybe other things i forgot.

    Summary:
      Fixed missing 1st frame in dshow output.
    Revision:
      xvidcore--stable--1.0--patch-16

    From sysKin:
     * decoder flags were overwritten, this was preventing from outputing
       the first frame immediatly.

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.

2004-04-08 20:34:54 GMT		patch-10

    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.
