From 505f48f2373d86e67f243fa32a10296020c22532 Mon Sep 17 00:00:00 2001 From: Wojciech Kapsa Date: Mon, 26 Sep 2022 13:57:15 +0200 Subject: [PATCH] decklink: Add new persistent-id property and sort devices by persistent ID The order of the devices iterator from the SDK is undefined and can randomly change. Keep the device-number property for backwards compatibility and simplicity but prefer the persistent-id property and also use it for the device provider implementation.
