Description b3_1987 2019-09-28 17:33:08 UTC
Created attachment 122920 [details]
The first project (which will be imported in the second project)

Kdenlive 19.08 crashes when trying to render projects that have Kdenlive projects imported and inserted into tracks. It renders the part before it, then it crashes when it gets to rendering the inserted project. Sometimes it simply stalls when getting here, but most of the time the rendering crashes.


STEPS TO REPRODUCE
1. Create a project, import video files into it and put them into the tracks. Save the project.
2. Create another project and import the previous project into it. Add the project into the tracks and add some video before it (intro video).
3. Render the project.

OBSERVED RESULT
The rendering crashes when it gets to rendering the imported project.

ADDITIONAL INFORMATION
It sometimes "miraculously" manages to render the project, but it's very rare. I usually need to render the first project and then import the rendered video into the second project, which takes a lot more time.

It doesn't crash when I render on Windows. I have to wait until project "15sept2019-a" is completely imported into project bin. 

Please try with the current Kdenlive AppImage version 19.08.1b to see if there are any packaging issues https://files.kde.org/kdenlive/release/ 

If the problem/issue doesn't occur when using the AppImage, then it's your configuration or packaging.
 

But it takes 1hour to render the empty project 15sept2019-2 with 100% CPU. I added to issue: https://invent.kde.org/kde/kdenlive/issues/349

1. I do wait for the project to be fully loaded into the project bin. This are projects that I have already saved. I also deleted the kdenlive cache and waited for it to rebuild it for these projects - without any change. This isn't even something rare - I have several projects like this (this is my usual workflow, creating 2 projects, because I need to concatenate the video files and add the audio, then in the second project I can do the cutting/transitions etc. However, in the current version even transitions don't work any more for imported projects - they just crash the application).

2. As mentioned in a previous comment (https://bugs.kde.org/show_bug.cgi?id=412423#c2), this also happens with Kdenlive 19.08.1 AppImage (and yes, it's Kdenlive 19.08.1b, the latest available on the website).

My rendering to MP4 with the "empty" Kdenlive projects doesn’t crash. So it must be something with the content. 

It could be OGG file related. Could you make a test and exchange the OGG with MP3 files? Or do you have JPEG? If yes exchange this file with PNG. 

Or it could be MLT related: https://forum.kde.org/viewtopic.php?f=272&t=153419 .

Yes, you are right, it does render fine with MP3 instead of OGG. The project doesn't have JPEGs, only PNGs.

Actually, it sometimes fails for projects with MP3, not OGG, as well. I've just had a project where it rendered fine the first time (the same workflow, a project imported in another project). Then I had to edit the first project, to mute a sound track, and the second project (which imports the first one) doesn't render any more. The rendering crashes with a similar error and I can't make it render. I had to render the first project separately and import the rendered file in the second project, which doubles the render time.

The strange thing is that this bug is actually a regression. I've been using this workflow, the same video camera with the same settings and the same audio recorder with the same settings, using OGG and PNG and the same intro and ending for quite a while now (about 2 years). Up until Kdenlive 19.08, this didn't happen. With 19.08, it started doing this repeatedly - it does it more often with OGG, but I'm also having it randomly for MP3. So something surely has happened in the code.

Can you please update to the latest version (20.12.3 at the moment, https://kdenlive.org/en/download/) and report here whether this is still happening?
