Yup, I'm pretty sure it won't fit well at all with our (C)CLA -- to learn a bit more about the problems of AAC and such as combined with open source, try and look for google chrome (which, IIRC, includes a version of ffmpeg) topics on the subject -- (again) IIRC google pretty specifically (sub)licenses or will sublicense a bunch of those patents to chrome users and re-distributors which I imagine was a rather huge can of worms for them to accomplish. I can't find it now, but I could swear Chris DiBona actually did a bunch of e-mails about such a topic together with one of google's laywers. It might be worth getting in touch with them... ...also it seems like java is actually quite fine for encoding/decoding of low-level high-bandwidth things like audio and video, as long as you stay away from java.util.* and other high-level stuff like that and you tune your GC appropriately :) ciao, Leo --------------------------------------------------------------------- To unsubscribe, e-mail: general-unsubscr...@incubator.apache.org For additional commands, e-mail: general-h...@incubator.apache.org
