Description Simon 2020-04-03 20:07:59 UTC 
SUMMARY


STEPS TO REPRODUCE
1. Add a clip to the project bin
2. Play the clip
3. While the clip is playing, create a new folder in the project bin

OBSERVED RESULT
Kdenlive freezes

EXPECTED RESULT
Pink unicorns rain from heaven and all Covid-19 infections are healed
Comment 1 Simon 2020-04-03 20:20:09 UTC 
Actually it currently happens every time a clip is playing and I then select another item in the project bin.
Comment 2 emohr 2020-04-04 10:14:14 UTC 
I'm on windows, tested with the master, playback settings "audio backend" set to WinMM. 

While a clip is playing in the clip monitor I click "create folder" in the project bin -> playing is stopped and it creates the folder -> no crash
Comment 3 Simon 2020-04-04 21:38:53 UTC 
Thanks for testing!
At least it does not seem to be Audio related as I get the same crash when switching from SDL to RtAudio here.
Comment 4 Simon 2020-04-15 15:18:36 UTC 
I am trying to debug this issue as it is quite persistent, but no luck so far. The funny thing is that when I click the new clip, the clip monitor jumps to frame 0 of the current clip, but no frame of the new clip is loaded. I can still press the play/pause button on the clip monitor and it toggles once, then the UI completely freezes.
Comment 5 farid 2020-04-15 16:37:27 UTC 
I cannot reproduce. Canyou maybe share the clips that are causing this?
Comment 6 Simon 2020-04-15 19:02:07 UTC 
Sure. Can you reproduce with this project?

Comment 8 emohr 2020-04-15 19:34:55 UTC 
I tested as you showed. It doesn't crash but the "switch" from one clip to the other take in some cases some time. Here a log from Visual Studio showing this "switch":
