x264: cannot setup codec bitrate too low, IDC Level Auto

I recently upgraded to the release 2.6.0, and compiled it for Ubuntu 11.10 64bit. When I try to encode to x264 and I have IDC Level Auto, I get the error "cannot setup codec bitrate too low". When I set IDC Level 3.1, it seems ok.

This particular problem doesn't bother me as much as the more general problem. The x264 Configuration has some very bad default values, and it's not that easy to set it up from the description in the wiki. At the top of the x264 Configuration box, there is a Configuration menu, however none of the selections work. My guess is that the Configuration menu should work something like the -vpre medium option in ffmpeg. Are there some files I should have to make the Configuration menu work properly?

If it would help, I'll provide further information.

I fixed this in the patch below:

The problem was the IDC auto was being set to 0 when it should have been set to -1. Once this patch is committed to trunk, you can begin using IDC auto again in the latest nightly builds.
