I've installed melt from sources in Ubuntu 18.10, codename:cosmic Everything seems to be fine but when I'm trying to play some kdenlive file I got [producer_xml] failed to load filter "qtblend" [producer_xml] failed to load transition "qtblend"
When I made ./configure in the installation stage, I've detected no errors regarding Qt not found.
Which is the module that contains qtblend?
Any hint is appreciated.
Regards David
To see if qtblend is compiled in, run:
melt -query filters | grep qtblend
QT is compiled by default unless the configure script is not able to find your installation: https://github.com/mltframework/mlt/blob/master/src/modules/qt/configure
If QT is not found during configure, it will print out the message: "- Qt not found - disabling"
Setting qt_includedir, qt_libdir, or the $QTDIR environment variable can help.
MLT has a convenience script to compile MLT and all dependencies:
https://github.com/mltframework/mlt-scripts/blob/master/build/build-melt.sh
This script can be helpful to inspect to see how it works for QT.
