Kostya's Boring Codec World

I’ve spent two weekends and finally REd and wrote decoder for Re* Audio Lossless Format. With news like these I can deliberately call it Intel Audio Lossless Format.

So, what codecs we’re lacking so far?

• Intel Audio Coder — it’s quite similar to IMC (Music Coder) but not identical.
• Intel Layered Video Codec — probably it’s just h.263 variant, the only thing I know is that RealVideo 2 decoder was based on it (it’s mentioned in doxygen for Helix SDK I saw once in Internet somewhere and this supports that theory indirectly).
• ClearVideo — a licensed fractal-based codec. It’d be rather simple DCT-based codec if not for one catch: it uses domain search to generate codes that then are used for block unpacking (and in decoder too, it seems). Maybe these patents will help?
• Intel NGV — we’ll deal with it when it’s ready 🙂

Feel free to send any useful information about them, preferably working decoders of course.

After that we can claim full support of Real and Intel codec family.
