Of course it's better, it's one more. Read the rules!
The brains of the people who write it, obviously.
I'm just curious about the strategy of development. Do you actively adopt latest algorithms efficient in RD performance and/or complexity to improve the project? If so, how do you handle the patent problem -- carefully avoid those algorithms that are patent-protected, or just use them regardless of the patent?
Yes, we adopt the "latest algorithms" that we came up with, which are probably not patented, given that we came up with them. If you're suggesting we read IEEE papers or similar, I could probably get more useful insights by putting a cat on my keyboard with a text editor open.
Sure. Dark Shikari never seems to get tired of tutoring potential developers, but a written documentation would probably reach more people than actually show up on IRC.Submitting such to a journal would of course increase the average quality of the journal; whether you care about that is a separate matter from whether you want x264 to be documented.
