<div dir="ltr">Hi Peter and Tim, I tried several experiments and came to the conclusion that the problem lies in v4l2src as the port of uvch264_src from 0.10 to uvch264src for 1.x looked really straight forward IMHO when I did a file comparison and went over the porting guide. Whoever did it did a great job. v4l2src 0.10 to 1.x changed significantly...I really did not have a chance to go over the differences with the porting guide in hand for v4l2src (0.10 uvch264_src works for me and I had to move on to some other issues in my application). However, I did notice on a blog a conversation between Wim and other developers on a v4l2src architectural issue that seemed like it might pertain to this issue.

It doesn't indicate a problem in your application, but indicates something-that's-not-quite-right in some element. We are trying to get the order right here for some advanced use cases. You can ignore those warnings. They shouldn't have any side effects generally other than being annoying. It's not a 0.10 vs. 1.x thing, more of a 'unstable 1.1.x series vs. stable release series' thing. The warnings will go away in 1.2.0, even if we don't manage to fix them all (which is usually not too hard, just tedious).
