Yesterday DivXNetworks.Inc released v. 5.1 of their famous video codec including DivX Player 2.5.
The new version includes a lot improvements and bugfixes.

New: Added a new high-quality psychovisual mode that includes the following features: Texture cortex masking and rate distortion algorithm Hybrid mode (with texture cortex masking) Speed optimization Chroma operation (this option is not enabled by default for performance reasons; to enable it, create an empty file in C: called "DivxPvShapingChroma.txt" for "fast" mode and "DivxPvSimpleChroma.txt" for slow mode; testing shows only 1-2% gains in JND tests) The decoder has been rearchitected and is now 10 to 30% faster on all CPU platforms. The decoder now supports automatic post-processing during video playback. Added new features to the rate control modes of the encoder, including: A complexity vector log file An API that allows real-time control of rate control An API that allows forced I-frame insertion Improved: Redesigned encoder GUI. The new GUI is more accessible and simplifies overall usage. DivX 3 compatibility. (There were no problems detected on any of the more than 60 hours of test content.) Performance of Nth Pass strategy planning performance. Fixed: A bug that caused the quantizer to overshoot the bitrate following a transition to a complex scene. A bug that limited the interframe change in quantizer to the ideal quantizer or plus or minus 2. A bug in RGB32 to YUV conversion on Pentium 4 machines. A minor bug that affected multiple CPU configuration. A bug with the rate control video buffer verifier (VBV) that would enforce a "3 sec" max bitrate. Several bugs that affected Nth Pass encoding strategy planning. A bug that caused a different number of frames to be reported between different passes in VirtualDub. A bug that caused motion vector (MV) reuse to be non-functional. A bug that caused problems when MV reuse and psychovisual mode were used together. Several bugs with the installer. A bug that caused a crash when setting crop/resize values. Download free version(AdWare included)

why not link to the free no-ad version, the one with 'lite' encoding tools.. that's the one most people need? |

Why bother linking to the free version when most readers here will install the Adware version anyway then run Adaware? |

as far as i know divx checs if gaim is installed when you run the adware encoding tools. but some people - like me - dont use the encoding tools in divx, so the free version is just the much better. |
