Allo Nicolas.
Pense-tu offrir les sources aussi? Hi Nicolas. Do you think you'll release the sources?

good question :-) The min quality was 32, but I limited it to 64 because of some (stupid ?) reasons. So you can't for the moment. And if you try to set the dead zone ratio below 256-ThresRatio you will see a beautifull bug. So I have to correct all this. Sorry :-) I have too much tested with the settings for a "middle" video quality... Nicolas |

This sounds definatly interesting. Can you please give some more information like
- is the codec meant for archive or capturing purpose? (i.e., which datarate does it perform at "best") - how fast is it? (i.e., does it do 720x576 in 20x realtime or is it more like 5fps) ... and so on. If we test it, we need to know the "design goal" to give a proper feedback. Thanks for your nice work, keep it up! Best regards Koepi

I'd like to know if it's I frames only in wavelet or if there is P frames too...

Won't we have greater quality by using p-frames?

So i still have to assume things and don't get any real insights? :P
Let me summarize: rududu codec is - an (integer?) wavelet (antonini 9/7 transform) codec - using I- and Pframes - using wavelets for compressing motion vectors (wtf? wavelets and motion vectors don't mix, sounds like a block based attempt again) - optimized for medium quality at unknown speed and for unknown purpose (archive quality / temporary capturing space+speed) - had better quality in the last beta version - written by Nicolas from france That's all we have about that codec for now. Or did I miss anything?

This seems correct with the infos we have now. Maybe Nicolas didn't understand your question...
From Koepi (Translated by Me): Ça a l'air vraiment intéressant. Pourais-tu svp nous donner des informations de plus comme - Est-ce que le codec a été conçu pour archiver ou pour capturer (c-a-d a quel kbps il donne la meilleure qualité) - Quel est sa vitesse? (c-a-d, est-ce qu'il fais du 720x576 a 20x la vitesse du temps réel (mouhahaha) ou c'est plus du 5 fps) ... et on continu! Si on doit le tester, on doit savoir le "but" pour pouvoir te donner des commentaires pertinents. Merci pour ton bon travail, lâche pas! Meilleurs veux Koepi

Thanks for translating that Sirber, my french is _really_ rotten ( I can't even "decompress" most of your french abbreviations ) and additionally, our main language here is english so that everyone has the chance to understand things.
Merci beaucoup pour tous (even that looks wrong to me - I need a refresh-your-french-class it seems), Koepi

I know what I _want_ to write
I only missed the tout<->tous difference. So after all it's (EDIT: = my french) not way worse as it was after school EDIT2: after reading this in english I think in german we're way shorter, here we just say "Danke für alles" - 3 words vs. 4 in french and 5 in english Regards Koepi
