It seems the codec has been <a href=\"http:\/\/forum.doom9.org\/showthread.php?t=150210\">on the radar for a few months now<\/a>. The decoder source code (Windows) is available for download, as are a bunch of samples. Is anyone interested in writing a proper description for this codec based on the source code? If so, I hope you can understand whatever (human) language the author wrote it in. Here are the core filenames:<\/p>\n<pre>\r\n$ wc *.cpp\r\n    1185    2217   37009 AdaptFiltrDequant.cpp\r\n    4375   13045  119493 BikubDetcimation.cpp\r\n   14075   42529  533493 DeblokFiltrCompDvij.cpp\r\n    1566    3110   57229 MotionArifmDecomp.cpp\r\n     820    2429   23311 Rgb_viu_kon.cpp\r\n   21588   70557  889709 SifDecompressor.cpp\r\n     118     408    3577 SifEkspotrFunk.cpp\r\n     394    1063   12274 SifFilter.cpp\r\n      96     323    2764 SifFiltrUprDialog.cpp\r\n   44217  135681 1678859 total\r\n<\/pre>\n<p>Okay, so maybe not all of those filenames are so bad, but I challenge you to decipher many of the identifiers in the source. Also, some of those files are a tad bulky. Large swaths of code are written only in inline MMX. I haven&#8217;t seen this since <a href=\"http:\/\/wiki.multimedia.cx\/index.php?title=Lagarith\">Lagarith<\/a>. I have this weird feeling that this codec is going to exist in its own little universe for a long time to come even though the author seems to have invested a lot of research into making it competitive with H.264.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A new alternative codec is in
