+Subject: [PATCH 3/8] Support setting the display framerate directly when possible.
+
+If can_set_display_framerate is set to true, TIDmaiVideoSink will attempt to
+set the display framerate directly in DMAI, instead of trying to simulate the
+desired framerate by occasionally repeating frames.
+
+Platforms that support this will need to enable it explicitly.
