Download XviD 1.1.0 beta 1

The developers behind XviD have released the first beta of version 1.1.0 of their open-source video codec. As usual, only the source code is made available for download. Edouard Gomez mentioned that the API in this release is still close to that of the 1.0.x release. Only a few things have changed, meaning that the 1.1.x libraries can be used with current 1.0.x client applications. Below are all the changes since version 1.0.3:

xvidcore

• The new department:
  • Rate-Distortion mode decision for bvops.
  • Two new postprocessing functions, brightness and deringing
  • VBV support in 2pass mode
  • Brand new PowerPC port by Christoph Naegeli (MacOSX users may be interested by the Quicktime component, have a look at http://people.ee.ethz.ch/~naegelic/index.php†
  • Brand new amd64 Linux 64bit port by Andre Werthmann
  • Out of the box yasm support (Required by the amd64 port, see: http://www.tortall.net/projects/yasm/†
• The changes department:
  • Everywhere encoder speedup, especially for b-frames and all vhq modes.
  • Speedup of the decoder, merging decoding steps together in order to save significant memory bandwidth, enabled mmx qpel support that was mysteriously disabled in 1.0.x. All optimizations could lead to a 25% speedup, and something closer to 12% in average.
  • More ELF friendly assembly code for the ia32/amd64 ports (functions are declared as functions, and their size is also written to the resulting object files)
• Bug fixes department:
  • Fixes to the CBR/ABR rate controller, it should work much better with bvops now.
  • Fix to the 2pass2 code that could cause doubling the overflow.
• Dropped features:
  • Reduced resolution vops no longer supported

VFW front end
