From 19772ffe102ab2e72d0f9f1403e0c02fcca4424d Mon Sep 17 00:00:00 2001 From: Paul Elder Date: Mon, 24 May 2021 18:37:14 +0900 Subject: controls: Split FrameDurations into FrameDuration and FrameDurationLimits We need a separate control to report the nominal frame duration, but it's also useful to report the min/max frame duration values that will be used. Split the FrameDurations control into FrameDuration and FrameDurationLimits respectively to support both of these.
