When exporting video to any other format, shotcut calls /usr/bin/qmelt, but qmelt not in tree.
Steps to Reproduce:
1. Open any video file
2. Choose "Export"
3. Press "Export" button
4. Look in log
/usr/bin/nice: «/usr/bin/qmelt»: No such file or directory
Failed with exit code 127
[Debug ] <MeltJob::start> "/usr/bin/qmelt" ("-verbose", "-progress2", "-abort", "/tmp/shotcut-ACxlju.mlt")
[Info ] <AbstractJob::onFinished> job failed with 127
Convert file to another format

maybe need qmelt in tree? or symlink melt -> qmelt
>> maybe need qmelt in tree? or symlink melt -> qmelt
symlinking will not work because qmelt is a totally different app - part from webvfx
Actually none of the shotcut portage versions do work, because the package needs an mlt engine that is missing totally in Gentoo. The problem is described here: https://github.com/mltframework/shotcut/issues/284
and here: https://forum.shotcut.org/t/usr-bin-nice-usr-bin-qmelt-no-such-file-or-directory/1414
Basically openshot needs: https://github.com/mltframework/webvfx and without it it is non functional when you get to export things.
I've created a very basic ebuild for webvfx, but it needs some polishing and some changes in the ebuild of shotcut, so I do not upload this here... but the discussion can be found here: https://forums.gentoo.org/viewtopic-p-8311200.html#8311200
How much sense does it even make to keep shotcut in tree if it is missing a critical RDEPEND?
Well if you include the webvfx ebuild in tree it makes sense :)
Besides shotcut is a very popular application (at least in other distributions) and removing it from Gentoo will be shame :)
Then someone should step up and maintain the required package.
Shotcut needs webvfx to export, unfortunately there's no ebuild in the tree and the linked ebuild in comment 2 does not work, fails on install with:
Files matching a file type that is not allowed:
* ERROR: media-libs/webvfx-1.1.0::tcgOverlay failed:
* multilib-strict check failed!
Shotcut can't export, Kdenlive crashes after upgrade to qt-5.14, video editing is about dead on Gentoo.
Ebuild for webvfx, provides qmelt support to Shotcut
works here, no guarantees
Should be fixed by media-video/shotcut-19.12.31.
