Bug ID: 395183
Summary: recording in clip monitor always crashes kdenlive
Product: kdenlive
Version: 18.04.1
Platform: Other
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: NOR
Component: User Interface
Assignee: j...@kdenlive.org
Reporter: kde-b...@adamspiers.org
Target Milestone: ---
How to reproduce:
1. start kdenlive (already configured to record video from my USB webcam)
2. click the + icon (Show Record Control) in the clip monitor
3. click the red circle icon to start recording video / audio
4. click the red circle icon to stop recording video / audio
This crashes kdenlive 100% of the time for me.
