натолкнулся на новый декодер (freeware,с свободно распространяемым source code) 
homepage: http://www.sigmadesigns.com/products/MPEG4_video_encoder.htm
download: http://www.sigmadesigns.com/products/RMP4_download.htm
Sigma Designs' REALmagic® MPEG-4 Video Codec enables the creation of high-quality ISO-compliant MPEG-4 video bitstreams. As a standard Video for Windows (VfW) codec, your favorite VfW applications, such as Adobe® Premiere® or Ulead® VideoStudio™, can now be used to create your own content using the latest compression technology. In addition to producing high-quality video, MPEG-4 compresses much better than MPEG-2, reducing your file sizes and enabling up to 2 hours of content to be stored on a standard CD.
Key Features:
ISO MPEG-4 Advanced Simple Profile
Supports B-Frames for reduced file sizes
Provides Adaptive Quantization for optimized video quality
Includes Intelligent Deinterlacing for interlaced to progressive scan conversion
Supports VBR (variable bit rate) or CBR (constant bit rate) operation
Supports resolutions up to 720 x 576
Minimum System Requirements:
500 MHz or higher x86-compatible CPU
128MB RAM
24-bit VGA graphics
Supports Windows® 98SE, Me, 2000, and XP
* Please note that using a faster CPU reduces the encoding time

Дополнительная информация:
XviD development has been stopped! The Sigma Designs REALMagic MPEG-4 Video Codec contains wide portions of code taken from the XviD project. Soon after the initial release of the REALMagic codec the XviD developers have contacted Sigma and informed them about the GPL violation (for those who don't know, XviD is distributed under the GNU Public License - GPL - which demands that if you modify a GPL program you have to release it under the GPL, which in this case means that the source code of the Sigma codec must be freely available). Sigma promised to replace the stolen code, but the new version of the codec which was released this month only disguises the stolen code, it was not actually removed. Sigma was once again contacted and asked to remove the offending code but until today nothing has happened. Therefore the XviD team is now turning to the public in the hope to receive wide public support in their efforts to convince Sigma Designs to respect the terms of the GPL. And until the matter has been resolved XviD development will not continue.
That being said I hope all the forum members who saw their threads about the Sigma Codecs being closed will understand our motivation now. Internally we already knew what was going on but since the XviD authors first wanted to try and resolve this internally we respected their wishes and kept quiet about the matter at hand.
[Update] Sigma has issued a press release announcing the availability of the source code of their MPEG-4 codec and it's already up for download. However, not a word was lost about the XviD issue and the press release makes one think that the Sigma codec was entirely developed by Sigma so we might be hearing more about this.
[Update] I found a GPL notice in some of the source code files, but it also looks like Sigma placed their own copyright lines there and XviD doesn't get any credit in the source either. The GPL notice also collides with Sigma's Software Licensing Agreement that you have to sign before downloading codec or source. On on the same issue DivXNetworks said they'd fully support XviD in this issue and apparently DXn's relationship with Sigma didn't really work out either, as Sigma's Xcard is not as DivX compatible as it was advertised. |
