Hi,
If you have a little spare time, it would be very helpful if you can answer this survey that takes less than a minute to complete: https://surveymonkey.com/s/FY89BTX
It will help determine if a specific flavor of a performance optimization proposal currently discussed [1] on the Multimedia mailing list [2] can be implemented without impacting image quality in a noticeable way.
Thanks, Gilles
