Description:

Exporting a new project to a mp4 file renders only black screen without audio.
Loading old projects and exporting are rendering correctly.

This happens when mlt6 and mlt7 are installed in parallel.

It looks like it picks up some wrong libraries from the mlt6 packages and does not understand the new mlt file format.

Additional info:

* shotcut 21.05.01-1


Additional packages:

* extra/mlt6 6.26.1-1
* extra/mlt 7.0.0-3
* extra/kdenlive 21.04.0-2


Steps to reproduce:
Start shotcut, open a file, move it to the timeline and export file -> renders black

Two solutions found:
1) Changing tags <chain> to <producer> in mlt project file and set rgba to rgba24a (old settings, mlt6)
2) Remove kdenlive and mlt6 and make a symlink /usr/bin/mlt-7 /usr/bin/mlt
This task depends upon
