Kdenlive

Install with the latest video codecs

Choice a.
Download an Appimage which includes Kdenlive, MLT, libav etc and allows kdenlive to be run stand-alone from any previous install of these modules on the system, from.. kdenlive.org/download/

the only problem is it loads 660mb into /tmp with every load up.

Then make the Appimage executable and run it with ./Kdenlive*

(It loads up fine but video rendering crashes for me, a Qt problem that I can't manage to fix)


I put it in ~/kdenlive and make a symlink to it (because of its version number in the Appimage name)

cd ~/kdenlive ln -s Kdenlive*AppImage Kdenlive.app  

You can unpack the App Image and keep all the app libraries in a home dir - then you can easily copy render profiles and UI settings from a previous version.
This also sees that no files are unloaded to /tmp.

first find offset no. need to mount the image..

./Kdenlive*.AppImage --appimage-offset  

Then mount it and copy out the contents..

sudo mount -o loop -o offset=112888 K*AppImage /mnt mkdir ~/kdenlive/extracted/ rsync -ar /mnt/* ~/kdenlive/extracted/ sudo umount /mnt  

make a .desktop file with

nano ~/.local/share/applications/kde4/kdenlive-app.desktop  

[Desktop Entry] Name=Kdenlive Comment=KDE non linear video editor Type=Application Exec=/home/user/kdenlive/extracted/AppRun Categories=AudioVideo Icon=/home/user/kdenlive/extracted/kdenlive.png  

just change your user name!


Also, important, make the kdenlive runtime dir with..

sudo mkdir -p /run/user/1000 ; sudo chown -R $USER:$USER /run/user/1000  

I can't get past this error and renders crash:

mlt_repository_init: failed to dlopen /home/dav/kdenlive/extracted/usr/lib/mlt/libmltgtk2.so
(/usr/lib/x86_64-linux-gnu/libpangoft2-1.0.so.0: undefined symbol: hb_buffer_set_cluster_level)

Choice b.
use the build script to install the latest versions of Kdenlive, libav, mlt rendering engine, and x264 into a directory without changing anything on the system.

Kdenlive/Development/KF5#A_build_script


migrate config files if you previously used Kdenlive (check locations of new install first)

cp ~/.kde/share/config/kdenliverc ~/kdenlive/.kde/share/config/ cp ~/.kde/share/config/kdeglobals ~/kdenlive/.kde/share/config/ cp ~/.kde/share/apps/kdenlive/kdenliveui.rc ~/kdenlive/share/apps/kdenlive/  

But make sure the environmentals point to the bin files in the new kdenlive directory

leafpad ~/kdenlive/.kde/share/config/kdenliverc  

[env] .. ffmpegpath[$e]=$HOME/kdenlive/bin/ffmpeg ffplaypath[$e]=$HOME/kdenlive/bin/ffplay mltpath[$e]=$HOME/kdenlive/share/mlt/profiles/ rendererpath[$e]=$HOME/kdenlive/bin/melt  

or, remove those lines from the file (if they point to /usr/bin/) and run the start-up script and kdenlive will add the lines with the local env.

edit the kdenlive .desktop file with

Exec=/home/your-user-name/kdenlive/start-kdenlive  

Choice c.
build kdenlive/ffmpeg/mlt from source see dev page

download MLT from sourceforge mlt/files/
or follow this guide to pull from git kevin.deldycke.com...

get mlt build dependencies

sudo apt-get install build-essential pkg-config libavformat-dev libavdevice-dev frei0r-plugins-dev frei0r-plugins libgtk2.0-dev libexif-dev libsdl1.2-dev libsox-dev libxml2-dev ladspa-sdk libcairo2-dev libswscale-dev qtscript5-dev libqt5svg5-dev libqt5opengl5-dev libepoxy-dev libeigen3-dev libfftw3-dev git yasm libtool automake autoconf libtool-bin libtheora-bin libtheora-dev intltool swig libmp3lame-dev libgavl-dev libsamplerate0-dev libjack-dev libsoup2.4-dev python-dev libkf5crash-dev libkf5filemetadata-dev  

if you previously had mlt installed, remove it with

sudo dpkg --remove --force-depends libmlt2 libmlt++3 libmlt-data melt  

cd to the mlt directory and run:

./configure --enable-gpl --enable-gpl3 --avformat-shared=/usr/local --avformat-suffix=mlt make sudo make install
