Description Evert Vorster 2016-06-23 05:24:57 UTC 
I noticed you commited an "fix memleaks" in git today. 
Having just recently installed Valgrind, I decided to let it run against kdenlive to see what it says. 
Of course it's painfully slow, and it shows a whole host of errors in mlt and kdenlive. 

I have compiled both with full debugging symbols, so it points right at the worst memory errors and unintialized variables, etc. 

I'll attach the logs here, and file a report for mlt as well.


In both cases, I started kdenlive through Valgrind, with a 1080p profile, which uses 720p proxy clips. Then I loaded on 4k clip, waited for the proxy to be made. Then I started a new project, same parameters, no save. Loaded another 4k clip, and once the proxy was made dragged it down to the timeline. 
Then I clicked onthe timeline to position the "playhead" on the clip, and to activate the project montior. 

Then I exited the program. 
Attaching the logfiles now. 

Reproducible: Always

full valgrind log

This is the full log of the command:
valgrind -v --track-origins=yes --log-file=kdenlive.valgrind.2016-06-22.txt kdenlive

Both mlt and kdenlive has been built with debugging on, and nothing stripped out.

Should be fixed with Kdenlive version 16.08
Comment 4 Evert Vorster 2018-10-13 04:56:09 UTC 
I will provide valgrinds upon request for any branch where we are cleaning it up.
