Moi, je crois qu'il faut attendre le VP7 version 2 ou 3. Ce codec a été lancer beaucoup trop prématurément.
Pour preuve :1- On accumule les bugs
MAJEURS chez On2 !
QUOTE(on2tech)
Current Issues:
Encoding Speed
Our encoder speed is slower than we'd like. We've been working hard to make it run faster and will continue to do so. I think some of the beta testers can probably attest that its a lot faster than the earlier versions. We're working on this issue.
Problems running from certain apps
We have also had people report to us that the codec doesn't work in a couple of apps ( though it seems to work in vdbub). We are trying hard to resolve this issue and hope to have a fix up early this week.
Encodes on P3's, Celerons, Athlons worse Than P4's
We've also discovered and are working on currently a problem with encoding on different cpu's. On some processors the encoder is currently producing better results than others. ( We think there is a bug in either our sse optimized code or our mmx code) . It seems that our P4 routinely beat encodes using p3 Celerons, and athlon machines.
Decode Speed
We've made significant improvements to the decoding speed of our codec. ( You should be able to see some of these improvements by playing video through our truecast player). The recent release of the vfw codec did not have these improvements. The next version will. The improvements included roughly a 20% overall improvement in decode, and processor adaptive postprocessing ( we do the best post processing we can do based on the time spend decoding the frame)..
2- On promet des choses qui aurait déjà dû être fait dès le départ!
(Je parle ici du "Panel control" du décoder)

Its coming ( both encode and decode ). Its on our list of things to do. First we're trying to handle some of these other issues.
3- On met sur le marché un codec qui n'est pas capable de décoder les versions précédentes (inacceptable selon moi) !
Un exemple parmis tant d'autres, voir ici :

J'ai téléchargé le codec sur le site ON2, payé ma licence 19,99$, installé le programme, rentré le code, qui m'indique que c'est bon.
Mais RIAM ne le vois pas, et je ne peux pas lire mes anciens VP6.
4- On essait de se défendre contre les codecs en compétition !
(je crois qu'un produit bien fait (meilleur que la concurrence comme eux l'affirme) n'a pas besoin de justification pour affirmer sa notoriété face aux compétiteurs.)

Our tests show that we are either equal to or better than Nero's codec in almost all situations. If you find a clip upon which VP7 is not performing as well as Nero or some other codec we'd love to get your help in resolving the issue.
Ne pas oublier que On2 affirmait même avant la sorti officielle :
QUOTE
On2's VP7 codec is out. There's no changelog, but obviously it's better than anything else
Ainsi que :

On2 will release VP7, probably some time in 2005. Considering the results of VP6, we can probably expect good results from VP7 (outrageous claims by their marketing department notwithstanding )
5- On émet aucune nouvelle (aucune date) du coté de On2 sur une éventuelle mise à jour (à croire qu'on va attendre encore lontemps). À mon humble avis, toute bonne compagnie qui se respect se doit d'informer le consommateur (payant devons-nous dire) sur son planning et sur ses évolutions importantes et essentiels au bon fonctionnement du dit codec.
Pour ceux qui veulent émettre des commentaires, des bugs ou des suggestions à On2 peuvent le faire via cette adresse courriel :
