Without it, Kdenlive's features will be reduced. You can simply install frei0r-plugins from your package manager. * - Breeze icons - Many icons used by Kdenlive come from the Breeze Icons package. Without it, many parts of the UI will not appear correctly. You can simply install breeze-icon-theme or breeze-icons from your package manager. * - MediaInfo - Download and install MediaInfo from |media_info| My MLT installation cannot be found, or Kdenlive cannot start MLT backend ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ There is obviously something wrong with your MLT installation. Either it is not installed or not in a standard location. You can test your MLT installation from a terminal by typing ``melt color:red``. This should bring up a red window (press :kbd:`q` to close it). - If you see an error message try reinstalling MLT or check that you don't have several versions installed on the system - If you see the red window, check where your MLT is installed: ``which melt``. Then delete Kdenlive's config file (:file:`$HOME/.config/kdenliverc`) and restart Kdenlive. Kdenlive says a MLT module is missing. What do I do? ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ An MLT dependency is missing and it is required to install it. .. list-table:: :widths: 30 70 :class: table-wrap * - SDL - Is used to output audio. Install `libsdl 1.x` from your package manager. * - Avformat - Is the FFmpeg module. Make sure you have ffmpeg installed on your system. * - XML - Make sure libxml2 is installed. On Windows, ensure that no conflicting libxml2.dll is placed in `C:\\Windows\\System32` or comparable folders. If you find a `libxml2.dll` there, try to rename it to `libxml2.old.dll` and then to restart kdenlive. Note that renaming `libxml2.dll` in folder `System32` may break whichever other app has put libxml2.dll there. It says that the following codecs were not found in my system... ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Some audio / video codecs are not installed by default. Installing a package called ``libavcodec-extra`` might solve the problem. On openSuse, you need to add the |packman_repository|, then enable |replace_vendor_package| on the packman repository.
