Well, the kernel issue is now defintily fixed, so it shouldn't be a problem in the future, libv4l2 can now be disabled, so we can workaround any issues with it. As for libavcodec, they don't offer any garanties on the API, so it usually causes some breakdowns from time to time, but this is true for all aplications. I actually tend to fix things rather quickly, unfurtunately in the case of Ubuntu they can take some time to upgrade, so you are left with a non working version until the next release. For debian it's easier since it's a rolling realease, I just contact the mantainer and he upgrades to the current (fixed) version.
In the case of ubuntu, the only option is to use one of my ppa's for 14.10, the current testing version is now working fine, I've fixed all issues with both libavcodec and uvcvideo, so I'll release the new version both in sourceforge and in my stable ppa.
