This crashes for every format that I have tried.

[Olivier Girard (eolinwen)]

I don't know where is the problem as you are using an Opensuse (and not me)
but I note that you have still some part from MLT in the version 0.7.8. And
that, it is not normal.
Could you use H264 and mp3 with your version of ffmpeg ?
Take a look in the Preferences, if you have this codecs or run and
copy/paste openshot in a console.

[Don Harter (harterc2)]

I tried previously to run gdb , but it doesn't recognize the python openshot as a binary file. Some of my files come from packman. I don't have mp3 as an option with h264 in openshot. Perhaps my version off fmpeg does not have it. I looked at similar bug reports and saw that different version of libavc and ffmpeg can cause problems. Also that one is the subset of anoher. I will try to install a different version of ffmepg and/or maybe uninstall libavc if that is a subset of the full version of ffmpeg. mp may have been disabled by suse because of licensing problems.

[Don Harter (harterc2)]

I found that I had a suse version of ffmpeg installed. I replaced that with the packman version. I still get this problem:

I see a choice for mp3 format but it is listed as a video format in the drop down box menu.

I ttried with mp2 as the audio format. It also crashed and here is the output from the konsole:

Perhaps I need ot remove libavc packages since they are contained in ffmpeg??

[Don Harter (harterc2)]

I am in the process of building my own rpms from the latest source files. I can see that there is a problem with the spec file for mlt. It does not recognize qt4 properly. The test looks for qt4 files in the wrong directory for suse kde.
Does anyone know what versions of ffmeg and mlt work with the latest stable open shot?

[Olivier Girard (eolinwen)]

Effectively you could have different versions of ffmpeg.

You seems to have a problem with alsa.
Hum you could choice between alsa and pulseaudio but :
like I have reformated my HD and turn on my SSD, I don't keep the link for
dependencies.
Secondly, I am not sure that the same for Suse.

If I could give you an advice, you should take a look at our forum (
http://www.openshotusers.com/forum) and search the topic about dependencies
for the version 1.4.x in the section installation (if my memory is still
good). If this one is always still good, you 'll find normally for
Opensuse, mandriva, Ubuntu, Debian, Slackware,................

If you want to create your own rpm (for MLT) good luck.

[Don Harter (harterc2)]

I built some rpms for mlt using mlt-x0.9.0.
No change it crashed still.
From the terminal:
ALSA lib pcm.c:7339:(snd_pcm_recover) underrun occurred

So upgrading to ffmpeg-1.2.1 and mlt-0.9.0 doesn't seem to fix the problem.

[Andy Finch (fincha)]

I don't quite understand where the crash is coming from, "QApplication was not created in the main() thread" is a QT generated message, OpenShot is a GTK app, so I'm a bit confused as to what is running here.

[Don Harter (harterc2)]

I am running kde/qt.
I upgraded to the latest qt4 tools package and that did not fix it.
I was beginning to suspect lib x11 or a fglrx64 proprietary driver issue.

I thought that many gnome programs run under kde through some interface. Perhaps there is a problem with that. Do you know what package that might be?

openshot is the only linux video editing program that has worked decently for me to edit x.264 video.

[Andy Finch (fincha)]

Sorry, I don't know. I always thought the GTK libraries were installed and run directly. Have you tried the export presets in the simple tab without changing anything in the advanced tab?

[Don Harter (harterc2)]

I have tried the preset tabs before and they also crashed.
I u pgraded my libx11 to the latest package and that did not fix it.

I moved the video files off my USB drive to a standard one. That did not fix it.

I tried to run gnome but that requires systemd in opensuse 12.2, and I have banned that program from my system.

I might temporarily install systemd so that I can try gnome.
I might also try without the proprietary video driver fglrx in X11. I wouldn't have hardware acceleration though. That driver has caused weird problems for some persons.

I did a little research and it seems that gnome and kde programs can coexist in suse12.2. The proper drivers just have to be loaded.

I don't think that I have enough disk space to install all the debug and source packages to use gdb further.

I tried it without the proprietary X driver,fglrx. That did not fix it. Rendering runs until it about 30% complete then it crashes as usual. I tried the simplified tabs again, selecting blue ray.

[Don Harter (harterc2)]

I started X with gnome. I then tried to export and it crashed.
The backtrace looks the same as the kde one. But what is that file doing there. I thought it was a kde file. Or is that a special way that suse does gnome, on top of qt/kde?

I also tried it without the fglrx driver and that did not fix it.
The problem seems to be in qt toolkit or lilb X11. Both of those packages were upgraded, but bugs may still be in there. Perhaps I should regress to an earlier package.

[Don Harter (harterc2)]

I decided to try the memory leak tool valgrind. It reported what seemed to be many memory leaks. I wonder if some of those are false leaks.
Here is the command that I ran:
valgrind --tool=memcheck --trace-children=yes --error-limit=no --leak-check=full ./openshot | tee debug
Here is a summary of the final report:
==622== LEAK SUMMARY:

My debug file is basically empty so I ,perhaps, should have run it with >&

Here are a few final lines. I will have to rerun it. It crashed before rendering was complete.

Looking for memory leaks I tried libsafe and it still crashed.
I then rebuilt the mlt packages with electric fence. When I ran openshot the menu items were not functional.
I tried some other export formats but they also crashed. Perhaps it doesn't make a difference because of the format of my project files.

I used the DVD boot disk for openshot and was able to export on this computer what segfaults now.

This is a very old bug please close it.
