SUMMARY STEPS TO REPRODUCE 1. Install Kdenlive under Ubuntu 19.10. 2. Try to Capturing Audio (Dubbing). OBSERVED RESULT Found that list of capturing device is empty with remark: "Make sure you have audio plugins installed on your system". EXPECTED RESULT Other programs like "SimpleScreenRecorder" work perfect with record audio from my laptop and microphone. I expected Kdenlive to record sound from the microphone without any problems. SOFTWARE/OS VERSIONS Ubuntu Linux: 19.10; KDE Frameworks 5.62.0; Qt 5.12.4.
Please try with the current Kdenlive AppImage version 19.12.2c to see if there are any packaging issues https://files.kde.org/kdenlive/release/ If the problem/issue doesn't occur when using the AppImage, then it's your configuration or packaging.
It was necessary to install the package "libqt5multimedia5-plugins". It is necessary that this package is automatically installed along with other dependencies, otherwise you can lose a lot of time until find a solution to the problem. I think this is a bug.
This seems to be a packaging issue. Do you have tested with the AppImage?
Yes, it is a packaging issue. "kdenlive-19.12.2-x86_64.appimage" work fine.
Please raise a bug with the packager. Kdenlive doesn't package for the OS.
