AdaptiveI support

Hi,

Is AdaptiveI or AdaptiveB supported on a particular set of hardware or a particular API level?  The manual makes it sound like API 1.8 is the requirement.  I'm using 1.10 and I don't see any I-frames being inserted on scene changes.

I found this: https://software.intel.com/en-us/forums/intel-media-sdk/topic/530296 which seems to indicate that it isn't supported - is this true for all hardware/API levels, or just a specific generation?

I'm using API 1.10 on Linux with Ivy Bridge hardware.  If AdaptiveI is not supported, do you have any recommendations for how to improve performance on scene boundaries?  Should LookAhead work on this hardware?

Thanks,

Will
