Introduction and approach Fuzz-testing, also called Fuzzing, is an essential tool inside the tool-box of software developers and testers. The idea is simple yet effective: simply throw a huge amount of random test inputs at the target program, until you manage to get it to crash or otherwise misbehave. This crashes are often revealing some defects in the code, some overlooked corner-cases that are at best annoying for the end-user if she stumbles upon them, or at worse dangerous if the holes have security implications. As part of our refactoring efforts of the main components of Kdenlive, this is one of the tools we wanted to use to ensure as much stability as possible. Read More

If you followed Kdenlive's activity these last years, you know that we dedicated all our energy into a major code refactoring. During this period, which is not the most exciting since our first goal was to simply restore all the stable version's features, we were extremely lucky to see new people joining the core team, and investing a lot of time in the project.

On the 2nd of December, the Kdenlive team will be having a bug squash day in preparation for the major refactoring release due in April 2019. This is a great opportunity for interested developers to participate in the project. The team has triaged hundreds of reports, closing more than a hundred of them in the past month. We have also made a list of entry level bugs you can get started with. For the more seasoned developers, there are plenty of options – be it a shiny feature request or a challenge to polish some non-trivial edges. To hack Kdenlive you need to know C++, Qt, QML or KDE Frameworks. Those with knowledge of C can join the fun by improving MLT, the multimedia framework Kdenlive runs on. Those with no programming experience can join in testing fixes and features, as well as triaging more bug reports. Read More

Kdenlive 18.08.3 is out with updated build scripts as well as some compilation fixes. All work is focused on the refactoring branch so nothing major in this release. On the other hand in the Windows front some major breakthroughs were made like the fix of the play/pause lag as well as the ability to build Kdenlive directly from Windows. The next milestone is to kill the running process on exit making Kdenlive almost as stable as the Linux version. Read More
