Hello,
Thanks for the report and sorry for the late response, I only found
this issue today.
I had a look at the Shotcut source code and it does seem to copy files
from other projects to its bin directory [1] and read the melt-7
executable from a variable called "shotcutPath" [2].
I am attaching a tested patch that symlinks these executables to the
shotcut bin folder. It was based on the update to 21.10.31 at 51898 but
should work in the current version.
I also removed other variables in the 'wrap-executable phase that don't
seem to be used. MLT_PREFIX is only read in Darwin and PATH was set
only for ffmpeg, but in the patch ffmpeg is symlinked instead.

I see the a similar issue but when Shotcut tries to use FFmpeg: it looks for FFmpeg in the shotcut store directory.

So for a little recap, taking your message into account : * The first wrapper 'bin/shotcut' does have some 'export' including : export MLT_PREFIX="/gnu/store/<>-mlt-7.0.1" * The second wrapper (called by the first) misses this export and 3 others (No idea if this "intermediate" wrapper causes any problem. Looks harmless to me… which doesnt mean much ^^). * 'shotcut' depends on 'mlt' and there sits the 'melt-7' binary : /gnu/store/<>-mlt-7.0.1/bin/melt-7 * but when using the export function from within shotcut GUI, the program calls for 'mlt-7' with the absolute path inside shotcut directory : /gnu/store/<>-shotcut-21.06.29/bin/melt-7, where it fails. regards, Fulbert

I think you're correct that the '127' error is due to it not finding an executable, but I think that's happening because shotcut got double-wrapped (or wrapped incorrectly). Unfortunately I'm not knowledgeable with qt-wrapping so I can't help any further, but I hope that helps! -- Sarah
