Package: kdenlive
Version: 16.04.3-1
Severity: normal
Dear Maintainer,
I have a kdenlive project, HD 720p 25fps, with multiple tracks. On the first
track (Video 1, MP4/H.264/AAC source with 24 fps), I can apply the `compand`
filter as expected. On the second track (Audio 1, MKV/H.264/Opus source with 10
fps), when I do this, kdenlive crashes with a segfault in libavfilter.
I'm not really sure whether kdenlive, libmlt or libavfilter are at fault here,
feel free to reassign to these packages.
A gdb session log is attached, a coredump (amd64, 594MB, gzipped to 22 MB) is
available at
https://rohieb.name/stuff/temp/kdenlive-avfilter-compand-segfault.core.gz
Cheers,
Roland
