When applying transitions with alpha or overlay: If i try to preview the transition, the program crashes. When rendering, it stops to render when the effect in the timeline is "arrived". First, I had to install LADSPA-plugins, it told me. Now it just stops rendering. When I start kdenlive via terminal, it tells me something about OpenGLES and ThumbCreator (see URL). Reproducible: Always Steps to Reproduce: 1. add for example "overlay"-transition between two clips 2 a. start preview - crash OR 2 b. render - rendering stops (no crash). Actual Results: crash Expected Results: show the effect or render the video I tried it with installing ladspa-sdk and swh-plugins packages. Topic on this site: https://forum.kde.org/viewtopic.php?f=272&t=127270
it looks like the recent issue in frei0r that we fixed last week. Where did you get your kdenlive package? Are you using our PPA : https://launchpad.net/~kdenlive/+archive/ubuntu/kdenlive-stable
Hello, Yes, I am using this ppa and kdenlive is up-to-date.
Hi all! I was on my way to create on new bug report, but I think I am faceting the same issue as Pascal. First: I am running a Ubuntu Studio 16.04 up to date. I updated kdenlive from your PPA: Kdenlive: Version: 16.08.1 Using: KDE Frameworks 5.18.0 Qt 5.5.1 (built against 5.5.1) The xcb windowing system I can reproduce the following issue: I add 2 clips on a brand new project, then add a transition, when I click on preview => kdenlive crashes. As Pascal , the rendering stops when the transition came without crash . When I remove the transition the rendering is good until the end. I also reproduced this issue on 2 differents computer (one using a virtualbox). Always reproductible except some transitions: diaporama: ok affine : ok transition par balayage : ok dissoudre: ok I ran kdenlive with gdb and got the following stack traces: addition : Thread 65 "RenderThread" received signal SIGSEGV, Segmentation fault.

Fell free to ask me to do some additionnals tests. Aurélia
I'm actually seeing similar spurious crashes with recent git master Kdenlive installed from Kdenlive's ppa's. It's still unclear to me what causes these crashes. When I compile the same Kdenlive version from git master sources, I can run it without any crashes (neither LADSPA nor transition crashes).
Aurelia, can you please try to *re*install the frei0r package(s)? In my case a corrupted shared library file was causing my crashes. So to make sure that this isn't the cause on your system, can you please be so kind as to reinstall your frei0r packages? Thank you very much!
Hi Wegwerf! Thank you very much for your answer! Where did you download the frei0r packages? In my case i dwonloaded here: https://files.dyne.org/frei0r/ frei0r-plugins-1.5.0.tar.gz I will retry from the same link. and I'll tell you. Thanks!
I tried to reinstall (aptitude reinstall frei0r-plugins) -> same issue. I tried to build frei0r-plugins-1.5.0.tar.gz (after removing frei0r-plugins from ubuntu package, aptitude purge frei0r-plugins), I get the following error (running kdenlive with gdb): Thread 17 "RenderThread" received signal SIGSEGV, Segmentation fault. [Switching to Thread 0x7fff95100700 (LWP 26436)] burn::update (in3=<optimized out>, in2=<optimized out>, in1=<optimized out>, out=<optimized out>, time=<optimized out>, this=<optimized out>) at /home/toto/Téléchargements/frei0r-plugins-1.5.0/src/mixer2/burn/burn.cpp:65 65 dst[b] = (uint8_t) CLAMP0255(255 - tmp);
thank for your help...
Thank you for your helpful report! Now I'm wondering what went wrong. First, to be sure, did you use the burn effect? I'm asking to make sure that this is not some library mismatch with calls running wild. Second, can you check if when the segmentation fault happens in line 65, is dst 0? And has b some sane value, within widt*height*4 I assume?
Hi Wegwerf, thank again for your answer. I will try to answer you as well as I can because I feel a little "lost" ;-) ! First: " First, to be sure, did you use the burn effect": I tried to use the "Burn" transition--->crash (with the error that I past) but the crash happen also with the other transition the same as my first post... Only a few of them function : dissolve, affine, diaporama... Second : "can you check if when the segmentation fault happens in line 65, is dst 0" How can I check this ? Third: "has b some sane value, within widt*height*4 I assume?" I can't find this item in the shell, where can I find this? Tell me more please ! I'm really want to find what's wrong.... Thank you very much again! This evening with my computer I try again , I past here the bug when I ran Kdenlive with gdb, this time with "overlay" transition: aurelia@aurelia-desktop:~$ gdb /usr/bin/kdenlive GNU gdb (Ubuntu 7.11.1-0ubuntu1~16.04) 7.11.1 Copyright (C) 2016 Free Software Foundation, Inc.

If you run kdenlive from gdb, and it crashes, then you should be able to print the parameters. However, what is puzzling: you get crashes all the time, but in different places. Something's really broken here. But what?
Hello Wegwerf! maybe I find the command line to print backtrace from GDB : here http://web.mit.edu/gnu/doc/html/gdb_8.html I will test this evening. However, you said that for you the transition do not crash ...I'm asking my self with whitch version of Ubuntu are you ? How do you install kdenlive and do the update and upgrade in the aim of do the same as you .... For my part I run Ubuntu studio 16.04 is it the problem ? Am I the only one in this case? Tell me more . Thank and have a good day !
Kubuntu 16.04LTS, but others are also running stable with Ubuntu 16.04LTS.
Hi, I tried to use testing packages, so I did the following: Change "http://ppa.launchpad.net/kdenlive/kdenlive-stable/ubuntu xenial main" to "http://ppa.launchpad.net/kdenlive/kdenlive-testing/ubuntu xenial main" in /etc/apt/sources.list.d/kdenlive-ubuntu-kdenlive-stable-xenial.list run aptitude update && aptitude safe-upgrade The following packages were updated: libvidstab1.1 libmlt6 (6.3.0+git201608140258~ubuntu16.04.1 to 6.3.0+git201609270616~ubuntu16.04.1) libmlt-data (6.3.0+git201608140258~ubuntu16.04.1 to 6.3.0+git201609270616~ubuntu16.04.1) libmlt++3 (6.3.0+git201608140258~ubuntu16.04.1 to 6.3.0+git201609270616~ubuntu16.04.1) python-mlt (6.3.0+git201608140258~ubuntu16.04.1 to 6.3.0+git201609270616~ubuntu16.04.1) After this upgrade, Kdenlive does not crash anymore. I am going to do some additional tests and keep you updated. Regards, Aurélia
