linuxserver/kdenlive

Kdenlive is a powerful free and open source cross-platform video editing program made by the KDE community. Feature rich and production ready.

Supported Architectures

We utilise the docker manifest for multi-platform awareness. More information is available from docker here and our announcement here.

Simply pulling lscr.io/linuxserver/kdenlive:latest should retrieve the correct image for your arch, but you can also pull specific arch images via tags.

The architectures supported by this image are:

Architecture	Available	Tag
x86-64	✅	amd64-<version tag>
arm64	✅	arm64v8-<version tag>
armhf	✅	arm32v7-<version tag>

Application Setup

The application can be accessed at:

• http://yourhost:3000/

By default the user/pass is abc/abc, if you change your password or want to login manually to the GUI session for any reason use the following link:

• http://yourhost:3000/?login=true

You can also force login on the '/' path without this parameter by passing the environment variable -e AUTO_LOGIN=false.

Hardware Acceleration (x86_64 only)

In order to perform hardware transcoding you will need to mount a video device into the container. Some of the default hardware rendering/transcode profiles will point to devices in /dev/dri for vaapi_device. Make sure the profile you are using points to the correct device in the container. IE if you have intel integrated graphics along with an Nvdia or AMD video card you might have renderD128, renderD129, etc. To check which device is which use vainfo from inside the container: (right click the desktop and open xterm)

vainfo --display drm --device /dev/dri/renderD128

Intel/ATI/AMD

To leverage hardware acceleration you will need to mount /dev/dri video device inside of the conainer.

--device=/dev/dri:/dev/dri

We will automatically ensure the abc user inside of the container has the proper permissions to access this device.

Nvidia

Hardware acceleration users for Nvidia will need to install the container runtime provided by Nvidia on their host, instructions can be found here: https://github.com/NVIDIA/nvidia-docker

We automatically add the necessary environment variable that will utilise all the features available on a GPU on the host. Once nvidia-docker is installed on your host you will need to re/create the docker container with the nvidia container runtime --runtime=nvidia and add an environment variable -e NVIDIA_VISIBLE_DEVICES=all (can also be set to a specific gpu's UUID, this can be discovered by running nvidia-smi --query-gpu=gpu_name,gpu_uuid --format=csv ). NVIDIA automatically mounts the GPU and drivers from your host into the container.

Keyboard Layouts

This should match the layout on the computer you are accessing the container from. The keyboard layouts available for use are:

• da-dk-qwerty- Danish keyboard
• de-ch-qwertz- Swiss German keyboard (qwertz)
• de-de-qwertz- German keyboard (qwertz) - OSK available
• en-gb-qwerty- English (UK) keyboard
• en-us-qwerty- English (US) keyboard - OSK available DEFAULT
• es-es-qwerty- Spanish keyboard - OSK available
• fr-ch-qwertz- Swiss French keyboard (qwertz)
• fr-fr-azerty- French keyboard (azerty) - OSK available
• it-it-qwerty- Italian keyboard - OSK available
• ja-jp-qwerty- Japanese keyboard
• pt-br-qwerty- Portuguese Brazilian keyboard
• sv-se-qwerty- Swedish keyboard
• tr-tr-qwerty- Turkish-Q keyboard

Usage

Here are some example snippets to help you get started creating a container.

docker-compose (recommended, click here for more info)

---
version: "2.1"
services:
  kdenlive:
    image: lscr.io/linuxserver/kdenlive:latest
    container_name: kdenlive
    security_opt:
      - seccomp:unconfined #optional
    environment:
      - PUID=1000
      - PGID=1000
      - TZ=Europe/London
      - SUBFOLDER=/ #optional
      - KEYBOARD=en-us-qwerty #optional
    volumes:
      - /path/to/config:/config
    ports:
      - 3000:3000
    devices:
      - /dev/dri:/dev/dri #optional
    shm_size: "1gb" #optional
    restart: unless-stopped

docker cli (click here for more info)

docker run -d \
  --name=kdenlive \
  --security-opt seccomp=unconfined `#optional` \
  -e PUID=1000 \
  -e PGID=1000 \
  -e TZ=Europe/London \
  -e SUBFOLDER=/ `#optional` \
  -e KEYBOARD=en-us-qwerty `#optional` \
  -p 3000:3000 \
  -v /path/to/config:/config \
  --device /dev/dri:/dev/dri `#optional` \
  --shm-size="1gb" `#optional` \
  --restart unless-stopped \
  lscr.io/linuxserver/kdenlive:latest

Parameters

Container images are configured using parameters passed at runtime (such as those above). These parameters are separated by a colon and indicate <external>:<internal> respectively. For example, -p 8080:80 would expose port 80 from inside the container to be accessible from the host's IP on port 8080 outside the container.

Parameter	Function
-p 3000	Kdenlive desktop gui
-e PUID=1000	for UserID - see below for explanation
-e PGID=1000	for GroupID - see below for explanation
-e TZ=Europe/London	Specify a timezone to use EG Europe/London
-e SUBFOLDER=/	Specify a subfolder to use with reverse proxies, IE /subfolder/
-e KEYBOARD=en-us-qwerty	See the keyboard layouts section for more information and options.
-v /config	Users home directory in the container, stores local files and settings
--device /dev/dri	Add this for hardware acceleration (Linux hosts only)
--shm-size=	This might be needed to prevent crashing
--security-opt seccomp=unconfined	For Docker Engine only, this may be required depending on your Docker and storage configuration.

Environment variables from files (Docker secrets)

You can set any environment variable from a file by using a special prepend FILE__.

As an example:

-e FILE__PASSWORD=/run/secrets/mysecretpassword

Will set the environment variable PASSWORD based on the contents of the /run/secrets/mysecretpassword file.

Umask for running applications

For all of our images we provide the ability to override the default umask settings for services started within the containers using the optional -e UMASK=022 setting. Keep in mind umask is not chmod it subtracts from permissions based on it's value it does not add. Please read up here before asking for support.

User / Group Identifiers

When using volumes (-v flags) permissions issues can arise between the host OS and the container, we avoid this issue by allowing you to specify the user PUID and group PGID.

Ensure any volume directories on the host are owned by the same user you specify and any permissions issues will vanish like magic.

In this instance PUID=1000 and PGID=1000, to find yours use id user as below:

  $ id username
    uid=1000(dockeruser) gid=1000(dockergroup) groups=1000(dockergroup)

Docker Mods

We publish various Docker Mods to enable additional functionality within the containers. The list of Mods available for this image (if any) as well as universal mods that can be applied to any one of our images can be accessed via the dynamic badges above.

Support Info

• Shell access whilst the container is running: docker exec -it kdenlive /bin/bash
• To monitor the logs of the container in realtime: docker logs -f kdenlive
• container version number
  • docker inspect -f '{{ index .Config.Labels "build_version" }}' kdenlive
• image version number
  • docker inspect -f '{{ index .Config.Labels "build_version" }}' lscr.io/linuxserver/kdenlive:latest

Updating Info

Most of our images are static, versioned, and require an image update and container recreation to update the app inside. With some exceptions (ie. nextcloud, plex), we do not recommend or support updating apps inside the container. Please consult the Application Setup section above to see if it is recommended for the image.

Below are the instructions for updating containers:

Via Docker Compose

• Update all images: docker-compose pull
  • or update a single image: docker-compose pull kdenlive
• Let compose update all containers as necessary: docker-compose up -d
  • or update a single container: docker-compose up -d kdenlive
• You can also remove the old dangling images: docker image prune

Via Docker Run

• Update the image: docker pull lscr.io/linuxserver/kdenlive:latest
• Stop the running container: docker stop kdenlive
• Delete the container: docker rm kdenlive
• Recreate a new container with the same docker run parameters as instructed above (if mapped correctly to a host folder, your /config folder and settings will be preserved)
• You can also remove the old dangling images: docker image prune

Via Watchtower auto-updater (only use if you don't remember the original parameters)

• Pull the latest image at its tag and replace it with the same env variables in one run:

  docker run --rm \
  -v /var/run/docker.sock:/var/run/docker.sock \
  containrrr/watchtower \
  --run-once kdenlive
  

• You can also remove the old dangling images: docker image prune

Note: We do not endorse the use of Watchtower as a solution to automated updates of existing Docker containers. In fact we generally discourage automated updates. However, this is a useful tool for one-time manual updates of containers where you have forgotten the original parameters. In the long term, we highly recommend using Docker Compose.

Image Update Notifications - Diun (Docker Image Update Notifier)

• We recommend Diun for update notifications. Other tools that automatically update containers unattended are not recommended or supported.

Building locally

If you want to make local modifications to these images for development purposes or just to customize the logic:

git clone https://github.com/linuxserver/docker-kdenlive.git
cd docker-kdenlive
docker build \
  --no-cache \
  --pull \
  -t lscr.io/linuxserver/kdenlive:latest .

The ARM variants can be built on x86_64 hardware using multiarch/qemu-user-static

docker run --rm --privileged multiarch/qemu-user-static:register --reset

Once registered you can define the dockerfile to use with -f Dockerfile.aarch64.
