I've installed 0.9 from git and have been playing with it. So far, it's been exciting to see some of the new features, but I've run into some problems trying to work on a project I created with a prior build. I'm getting a crash with "Application: Kdenlive (kdenlive), signal: Floating point exception" when I do various tasks like select a video clip in the timeline or try to add a Pan/Zoom effect to another clip. I looked at the developer wiki to see what I need to do to debug this. The KdenliveBuilder wiki page seems like it would be helpful, but the kdelive_builder.sh tool is quite out of date (pulls from SVN, my gosh) and does not work. It's been several years since I've done any C or C++ development. I know I need to use gdb to step through the app, but I need to enable debugging symbols and I don't remember how to do that. Or, if there's an easy way to figure out from the KDE crash handler where in the code this floating point exception is occuring, I suppose that'd get me moving in the right direction. FWIW, I'm running on Fedora 16, 64-bit, qt 4.8.1. -- fo...@io... is Doran L. "Fozz" Barton "Something went wrong in jet crash, experts say" -- Headline seen in newspaper |

I'm debugging with QtCreator (open the CMakeLists.txt in the kdenlive folder, compile and run in debug mode); uses gdb too, but has a way better interface. KDevelop should do the job too. The CMake argument -DCMAKE_BUILD_TYPE=debug tells CMake to use debug flags (-g). Sometimes it is necessary to also use -O0 manually since stuff gets optimized away and variable values are not visible anymore. Simon |

It does appear in some kdenlive.org forum posts from a long time ago, but it is not official, it is not made by a kdenlive developer, and it is not under our control. Sorry you were misled. Still some things are useful in its wiki, just not the unmaintained build script. -- +-DRD-+ |

I'm giving kdevelop a try since it's easily installable from the Fedora repositories. I've got the kdenlive project open inside kdevelop and I'm able to configure, build, install, and "debug" from inside kdevelop, but I've run into an interesting problem: When I run kdenlive from the command line (/usr/local/bin/kdenlive) it works fine. When I run it from inside kdevelop, it does not think any of the MLT effects used in the file are installed. > Effect volume:normalise not found in MLT, it was removed from this project > Effect volume:normalise not found in MLT, it was removed from this project > Effect volume:normalise not found in MLT, it was removed from this project > Effect volume:fadeout not found in MLT, it was removed from this project > Effect brightness:fade_from_black not found in MLT, it was removed from this > project Effect affine:pan_zoom not found in MLT, it was removed from this > project Effect affine:pan_zoom not found in MLT, it was removed from this > project Effect affine:pan_zoom not found in MLT, it was removed from this > project Effect brightness:fade_to_black not found in MLT, it was removed > from this project Effect affine:pan_zoom not found in MLT, it was removed > from this project Effect affine:pan_zoom not found in MLT, it was removed > from this project Effect affine:pan_zoom not found in MLT, it was removed > from this project Effect affine:pan_zoom not found in MLT, it was removed > from this project Effect affine:pan_zoom not found in MLT, it was removed > from this project Effect affine:pan_zoom not found in MLT, it was removed > from this project Effect affine:pan_zoom not found in MLT, it was removed > from this project Effect affine:pan_zoom not found in MLT, it was removed > from this project Effect affine:pan_zoom not found in MLT, it was removed > from this project Effect affine:pan_zoom not found in MLT, it was removed > from this project Effect affine:pan_zoom not found in MLT, it was removed > from this project I'm a kdevelop novice.

My problem appears to be in producer_avformat.c on line 2384. I'm using ffmpeg 0.8.11 (because that is the most recent available for Fedora 16). Is that a problem? Should I be running a newer release of ffmpeg with kdenlive 0.9? I may just want to roll back to 0.8.x if that's the case because ffmpeg depends on x264 which a bunch of stuff depends on. It would be a dependency nightmare to resolve. -- fo...@io... is Doran L. "Fozz" Barton "Hitler, who had become depressed for some reason, crawled under Berlin.

Hi, There is an issue with composite transition crashing in producer_avformat that might well be causing your problems. Bug is reported here: http://kdenlive.org/mantis/view.php?id=2613 I am currently working on it. regards jb |
