GPL allows turning a VP8 encoder into an H264 encoder. The patent license only covers VP8, no?

If by writing code, you violate a patent, the license of your code does not prevent that, nor save/help you.

Yes. Patent law and copyright law are entirely different items. People lump them together and call them all 'IP', but it's not a accurate representation of how the law works.

Saying that you can take VP8 code and combine it with x264 to make a patent-free H.264 implementation (or whatever your approach is) is like saying: I paid my taxes this year so I can speed on the highway without fear of getting a ticket.

GPL and Patents

Yes, the GPL itself doesn't restrict you from turning a VP8 encoder into an H264 encoder. Patent laws restrict your legal ability to do so. As I understand it the GPL only covers granting rights to implement the current software and patents applicable to it's current implementation, not all possible permutations or extensions of the released code. Therefore, I believe granting permissions to include VP9 codecs is an extension of patent grants not required by the gpl. I see no reason why these patent grants would be gpl incompatible. I have absolutely no formal legal training and do not claim this to be sound legal advice. If you are uncertain of any legal issues please contact a trained solicitor/lawyer.

well in that case you have to drop everything from Fedora, because the GPL allows you to convert any software into a H264 encoder.

This includes all the software that Redhat owns the patents on (or purchased a license that covers all GPL uses as well)
