From 0a8d42501c1bf168bd852537bb3cd18490fac7ee Mon Sep 17 00:00:00 2001 From: Christian Kolset Date: Thu, 7 May 2026 14:46:20 -0600 Subject: Motion capture: camera selection dropdown MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replace camera index spinbox with a combo listing detected cameras by name. On Linux enumerates /dev/video* and reads device names from sysfs (fast, no probing). Fallback probes cv2.VideoCapture indices 0-7 on other platforms. Simulation entry always appended as last option. Also adds explicit simulation mode (index -1) to tracker.start() and a rescan button (⟳) in both the main window and the Settings > Plugins widget.
