Despite how it looks, I still monitor Discmaster for new additions in hope there’s something interesting there. Sometimes there is, which I can either postpone for later or actually take a look and try to figure out how it works. Here’s a list of stuff I looked at and found at least somewhat interesting:| Kostya's Boring Codec World

In my last post I mentioned DVI family of formats and I decided to extend NihAV support a bit. Previously I implemented YULELOG.AVS demuxing and decoding and stopped at it, but apparently there are six more samples that can be found with discmaster.textfiles.com (fun fact: SAMPLE.AVP is not detected as AVSS and out of four instances three are unknown and one got the embedded JPEG file decoded).| Kostya's Boring Codec World
Back in mid-1990s there was a situation when video on computers was slowly getting in demand while the processing power was still very limited. 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
As I mentioned last month, I decided to reverse engineer Motion Pixel codecs and after a lot of failed attempts to make decoder work I’ve finally got something.| 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
Since I have not tweaked any weights and have not made any releases, I’ll just write about some stuff I’ve been working on but have not released yet. Meanwhile librempeg got support for a bunch new formats too so its changelog may be a more interesting read. Anyway, this post is about what I have (and haven’t) done.| 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
