Description Adam Spiers 2018-06-09 17:39:58 UTC

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.

Comment 1 Patrick Silva 2018-06-15 22:53:21 UTC

it also crashes on Arch Linux when I stop video recording with my webcam.

Comment 2 emohr 2018-12-26 14:52:37 UTC

Please try with the current Kdenlive AppImage version 18.12.0c

Run the Appimage from the terminal (press CTRL + ALT + T). Move to the AppImage folder and run the .AppImage: ./Kdenlive*.AppImage

Comment 3 Adam Spiers 2018-12-27 17:57:25 UTC

Created attachment 117132 [details]
STDOUT/STDERR from 18.12.0c AppImage run

It still crashes for me on 18.12.0c, although sometimes immediately on pressing record, other times during recording, and other times during pressing stop.  I haven't figured out a pattern yet.

Comment 4 emohr 2020-03-08 17:00:39 UTC

Please try with the current Kdenlive AppImage version 19.12.3 to see if there are any packaging issues https://files.kde.org/kdenlive/release/ 

If the problem/issue doesn't occur when using the AppImage, then it's your configuration or packaging.

I see no way to record video with a webcam in kdenlive 20.07.70.
Was this feature removed?
