Openshot 2.0.5 crashes during export

[René Seindal]

Openshot 2.0.5 crashes practically every time during export. Sometimes after 4%, sometimes after 80%, but in maybe 20 attempts with many different settings, only one export ever finished and it took ages.

This is a Debian testing system, and Openshot is installed from deb-multimedia.org.

While I have no doubt that exporting works for others, and that the problem is most likely somehow on my system, I'm quite at a loss as to what is wrong.

There is nothing relevant in the log.

If I run launch-openshot from a terminal, I'm just told it segfaults.

I've tried to work a bit more on this.

My input files were short clips made with a Canon PowerShot D30 waterproof compact camera. The files are Quicktime (.MOV) with H.264 video and PCM 16 audio and 24 fps.

Making a very simple project with these files, loaded automatically on the timeline with a 2s overlap and fade in/out, the project failed to export and Openshot crashed regularly working on the project. Running openshot from a terminal indicated that it died on a segfault.

Transcoding the clips to MP4 (H.264 / AAC) @24fps with ffmpeg and creating the same project, openshot did not crash and the video exports OK. In this case the main problem is memory and I have seen a few cases where openshot died with the message "killed", probably due to lack of memory.

My computer has 4Gb ram and 7.5Gb swap. Openshot will regularly run at 7-9Gb virtual mem and 1.8-2.4Gb resident.

In any case, it seems that openshot is unhappy with the video files generated by the Canon D30 camera, since a simple transcode of the files will make it behave well.
