[x264-devel] preventing IDRs

If I want to disable IDRs completely except for the start of a stream and
when requested (via x264_encoder_invalidate_reference), should this be what
I'm setting in the x264_param_t struct?

 x264_params.i_scenecut_threshold = 0;
 x264_params.i_keyint_max = INT_MAX;
 x264_params.i_keyint_min = INT_MAX;

Also, should this be done before or after applying the profile?  It seems
like something that would survive the application of the profile, but I'm
currently doing it after.

Thanks!
