Old paletted video formats were slowly going away (Smacker still holding strong though) and for hi-colour video RLE was not a good choice in terms of compression and DCT was not a good choice in terms of CPU cycles required. Thus the niche was partially filled by block-based vector quantisation codecs (like Cinepak) and various codecs that compressed ...| Kostya's Boring Codec World

There is this very Sirius (or Sirius Publishing, more precisely) family of video codecs (plus one container format) apparently developed by two guys (who like to spam their name even in junk sections of AVI files). Also initially it had its own container format but later they’ve started to target AVI.| Kostya's Boring Codec World

Back in the day I looked at the format and recently, to distract myself from game formats, I decided that it might be a good not the worst idea to implement decoding it.| Kostya's Boring Codec World
Since I can’t do anything about the world largest countries run by over 70-year old dictators, I try to find a distraction elsewhere. It usually works only until the next time I read next. Anyway, here’s something different for a change.| Kostya's Boring Codec World
