From 4f2c94ba8b7f9f4d85a1d7e03f4c5272d92c3361 Mon Sep 17 00:00:00 2001
From: Hans de Goede <hdegoede@redhat.com>
Date: Wed, 24 Jan 2024 20:44:29 +0100
Subject: [PATCH 25/25] libcamera: debayer_cpu: Make the minimum size 1280x720
pipewire + firefox default to what looks like 640x480 if we export
the entire supported cropping range. Hardcode 720p as minsize for now.
