Yes, that's right that my codec is "closed" source and undocumented for the
moment, but this can be easily corrected.
(As I said in my first post), I have contacted Monty Montgomery first.I had
few but great discussions with him, and Monty also encouraged me to present
my work on the channel.But that's right that I don't know if he was ok that
I post that often at each update (will have to slow down)? Maybe the best
would be to ask directly to Monty and Xiph members if it is a polite way to
post on the Theora channel, or definitely not?
I have also sent to Monty all the source code of my codec and algorithm
detail (he also very kindly helped me to improve my codec).The problem is
that my codec is absolutely not finalized (my algorithm is definitely not
good on the 5% of rather compressed and "very blurred" images... and that's
a major drawback...), the source code would also really need to be cleaned
About all this, I think the best is maybe to have an answer from Monty
and/or Xiph core members?
Many thanks again for your time,
