I already told you that I asked scott bertin to help me with our auto-exposure problem. (Currently auto-exposure doesn't show up in v4l2ucp because it has an id which isn't queried.)

Scott Bertin answered me with a nice patch (v4l2ucp-extcontrols.patch) which led me to conlude that our code contains the problem. I found it and fixed it in the attached patch 0006. However I still face some difficulties with V4L2_CTRL_FLAG_NEXT_CTRL.

V4L2_CTRL_FLAG_NEXT_CTRL can be used by an app to automagically get the next available CID. That works fine as long as all CIDs are in a nice order like:
1,2,3,4

However in our code they are a bit mixed:
1,3,2,4

This leads to CID number 2 being missed because my algorithm can't process the fact that before CID 3 CID 2 should be sent. However CID 1 should not be sent twice.

Help me, Obi-Wan.

PS:The other patches are just there to provide a nice line from origin to patch 0006. But please free to discuss them, too.


Patch 0005 doesn't fix anything. I'll do that again.
