Subject: qvidcap: allow Q to close the window with option --no-loop Author: Hans Verkuil <hverk...@xs4all.nl> Date: Fri Feb 7 09:44:53 2025 +0100 If --no-loop was specified, and the end of the file was reached, it would just sleep forever. This blocked the use of 'q' to close the window since the Qt event loop was never called. Just return instead and let the event loop deal with it.
