Software-update: XviD 1.0.0 beta2

XviD is een open source MPEG4-codec en wordt gebruikt om filmbestanden te encoden. De nieuwste versie is genummerd als 1.0.0 beta2 en heeft als codename Ciao meegekregen. De volgende release notes zijn beschikbaar:

Changes since 1.0.0 beta1 (Aloha):
  • xvidcore:
    • MPEG4 compliance is back (beta1 was missing the VOS header)
    • matrix quantization is finally thread safe
    • improved vop type decision
    • 2pass2 plugin: min key interval was a misleading name. It's been renamed to kfthreshold. And as the kfthresholding behavior was a bit too aggressive, it's been disabled until we decide how it should behave w/o hurting quality
    • single plugin: fixed quant capping
    • interlacing artefacts fixed.
  • VFW fontend:
    • some misuses of xvidcore were fixed
    • min key frame widget renamed and moved to the 2pass panel
  • Debian package:
    • small errors in the control file reported and fixed by Nicolas Boos
  • Active Items to work on:
    • update vfw & dshow decoder frontends
      • GUI isn't perfect for vfw and dshow still links against xvid.dll which doesn't export internal functions anymore because of the license change.
    • decide on vfw & dshow linking policy. presently we statically link, however this increases the size of zips/packages where both vfw & dshow are included.
    • update/fix CBR plugin
      • misses target bitrate, bitrate burst in static motion/high motion transitions
    • bug hunting (ed.gomez/syskin)
      • xvidcore is still a place where bugs feel confortable
    • docbook writing (every developer should contribute)
      • New API has to be documented.
    • two pass code should not introduce quality regressions (every tester)
      • first feedback proved kfthresholding was hurting quality, a decision on its behavior has to be settled.
    • YV12/I420/USER clarification
      • item submited by Ivan Kalvachev Planes are swaped
    • MMX MPEG4 quantization is unprecise. This is probably an inherent problem in some MMX opcode precision.
Next beta releases will focus on tuning for better quality and/or speed. Though we don't know of any standard compliance problem at the moment, continue using beta releases with care.[break]De downloads staan op deze pagina klaar om geleeched en gecompileerd te worden .
