Les codecs vidéo DivX (qu'on ne présente plus) viennent de sortir en version 6.1 chez DivX, Inc. (anciennement DivX Networks). Ce qui change :

• Optimisations pour les processeurs simple core qui accélèrent l'encodage de 14 à 80%.
• Optimisations pour les processeurs Dual Core, HyperThreading et pour les systèmes multiprocesseurs qui accélèrent l'encodage jusqu'à 250 % (Dual Core + HT).
• Nouveau mode d'encodage haute qualité.
• Le mode DivX HD autorise un bitrate maximal de 6 Mbps.
• Corrections de bugs.
• Meilleur support du MPEG4.

Le lecteur DivX Player profite aussi des nouveautés suivantes :

• Gestionnaire de téléchargements permettant de télécharger plusieurs vidéos en même temps et de les lire progressivement.
• Fonction pour graver les fichiers DivX directement depuis le lecteur.
• Gestionnaire de médias pour organiser sa vidéothèque DivX.

Changelog Divx 6.1
 
New:
- Full support for single CPU, HyperThreaded (HT), dual CPU (SMP) and dual core processors. Encoding performance is improved up to 180% for HT CPUs and up to 250% for Dual Core + HT.
- Mutlithreading is enabled in the DivX decoder for DirectShow when the option to 'Reduce CPU spikes using one frame delay' is enabled and post-processing is applied.
- Optimizations have been added for processors supporting SSE2 extensions.
- A new "High Performance" encoding mode has been added.
- A new "1-Pass Target Quantizer" mode has been added.
- The codec now includes a Lanczos resize filter for very sharp resizing.
- The Feedback Window now displays VBV level and has variable axis for PSNR plots.
- The Feedback Window now contains controls for changing VBV bitrate, performance mode and psychovisual enhancement in real time during encoding.
- DivX High Definition profile now permits average bitrates of up to 6 Mbps.
- MPEG quantization has been improved.
- Brightness, contrast, and saturation controls are now respected by the DivX decoder for DirectShow.
- The DivX decoder for DirectShow now respects the option to "Output YUV 4:2:0 when supported."
- It is now possible to exclude the Settings Manager by using RegEdit to add the process name to the list under: HKLM\Software\DivXNetworks\DivX\SMExclusions.

Changed:
- The performance of "Extreme Quality" and "Insane Quality" modes has been improved.
- "Fastest" mode now achieves better compression and produces video compliant with certified encoding profiles.
- Quarter-pixel motion estimation has been enhanced for performance and is now available in all modes from "Balanced" through "Insane quality" when "Unconstrained profile" is selected.
- Item descriptions in the encoder GUI have been improved for all languages.
- Generic MPEG-4 playback support has been improved.

Mise a jour vers DiVX 6.1.1

New in this version

• Fixed a problem where some systems would crash as the Psychovisual Enhancement method was modified in the encoder configuration window.
• Improved B-frame decision.
• Improved rate control for very high bitrates.
• Fixed a problem that caused cropping to reduce performance.
• Fixed an issue where adjusting the VBV_bitrate slider in the Feedback Window would reset the VBV buffer occupancy.
• Improved Japanese encoder translations.
• Fixed a problem where the decoder may fail if both smooth playback and YUV output are enabled in the Decoder Configuration Utility.
• Fixed a post-processing issue in the decoder for multi-threading systems.
• Fixed a handle leak in the decoder.

Codecs Divx 6.2 pour windows dispo sur divx.com. On nous annonce:
Une vitesse d'encodage améliorée (jusqu'à 350%:rolleyes: plus rapide que DivX 6.0).
Optimisations pour les processeurs récents (dual-core, Hyperthreading) et moins récents.
Meilleure qualité d'encodage.
Support de nouveaux modes d'encodages avec possibilité d'ajouter ceux qui seront proposés par la communauté DivX.

changelog
 
New:

• A new encoder preset option allows you to quickly configure the encoder based upon your preference for encoding speed and video quality
• The DivX community codec replaces the current free version of DivX, offering a wider range of performance and quality options for free through encoder presets
• Multithreaded resize filters have been added for improved performance on all HyperThreaded (HT), dual CPU (SMP) and dual core processors
• A new "Enhanced multithreading" option capable of increasing encoding rate depending on system configuration and encoding environment
• A new "Enhance texture" psychovisual enhancement method that improves picture details around keyframes and reduces the appearance of stray blocks under fast motion when encoding at lower bitrates
• MMX optimizations for the MPEG quantization method
• The DivX decoder can anonymously check for updates to the DivX codec, ensuring you are always notified of newer versions

Fixed:

• Fixed a problem where multiple instances of the feedback window would cause the encoder to fail
• Fixed a problem where very old DivX 5.0 content might not be decoded correctly
• The encoder GUI now adapts to screen resolutions of 800x600 or lower

Changed

• Bitrate modulation for multipass nth pass encoding is now preset at an optimal value for quality. As a result, this option has been removed from the user interface
• The DivX Pro 6 month trial has been replaced by a 15 day trial, which can be started from the DivX encoder GUI, rather than during installation. This is because a much wider range of features are now available for free in the community codec. Previously installed 6 month trials will be honored.

Mais on nous annonce une compression 350%:rolleyes: plus rapide et un gain de qualite...

Allez M. DivX, encore un petit effort et on pourra mettre un film sur une disquette en qualité DVD et avec les sous titres et les bonus .

Une version 6.2.2 vient de voir le jour. A mon avis une correction de bug de la version 6.2
