Kostya's Boring Codec World

I just had to express that. Recently I’ve opportunity to examine two DVD disks – one with 8 films-in-one and another one is 7 films-in-one (our pirates usually pack at least two films on each disk). Every DVD has a proud label ‘Real DVD Quality’ (but sometimes even VHS tapes are marked so).
As expected, those films had slightly lesser resolution than 720×576, one disk had 352×576 films, but another one… 352×288 !!! If disk was labeled ‘Real VCD Quality’ – that should be fair.

I’ve committed today another decoder – for KMVC codec, used in Worms games. This is the final step to the completion of my task.
Multimedia Mike has a simple goal – to have a player which will play any multimedia file you like. My task for now is much simpler – have a decoder for each letter of alphabet.
With the latest addition there are only two letters left: E and Y. But considering that TSCC is now called Ensharpen and only known formats on Y are YUV variants, I declare this task complete. Future RE’ing will be just for fun 😉

Here is a list of codecs I reverse engineered in some way.

Codecs RE’d by format analyzing

• Apple QuickDraw
• Autodesk RLE
• Sierra On-line Audio
• TechSmith capturing codec (aka Ensharpen)
• Pinnacle/Miro XL

Most of those are RLE variants (actually 2 of 3 are MS RLE variants).

Sources->Description->New Code

• LOCO codec
• Duck TrueMotion 2
• IBM Ultimotion
• Winnov WNV1

The last one is re-created from tuner driver.

Binary RE’d

• Creative ADPCM
• Intel Indeo 2
• Q-team QPEG
• DSP Group TrueSpeech

Welcome to new BLOG dedicated to RE’ing of codecs. I noted, that posting a description of codecs helps very much in process of their RE’ing. This will be the place to do it.
