Description
Describe the bug
Audio is muted when doing stutter loops (copy/pasting the same 1 frame clip multiple times), but video is fine.
Splitting the clip to 2 frames seems to fix the issue, but its still annoying.
To Reproduce
Steps to reproduce the behavior:
- Open Shotcut
- Open a file
- Drag it into the timeline
- Split the clip at 1 frame
- Copy paste it multiple times
- Play the timeline/Render the video
Expected behavior
Expected the audio to be affected,both in playback and in render
Desktop (please complete the following information):
- OS: Q4OS
- OS Version: 6.1
- MLT/melt version: 7.32
