I’ll update codec details on our wiki and hopefully can forget about it. Let somebody French-speaking complete it.
There are many codecs out there to reverse engineer, including worthier ones. On the second thought that would define almost every codec.
Update: filled all information I had, the rest is up to somebody with the debugger and motivation to do it.
any chance of posting your hack partial decoder?
Yes, maybe in a week or so. The code is ugly that I’m not going to submit it without a major cleanup even as RFC.
