DOVE - Online Video Editor

DOVE — Online Video Editor

DOVE is an API driven Video/Audio Editor for live mixing with an intuitive web based Interface. Developed by and for DORFTV. Inspired by bbc/brave.

Concept

Inputs → Scenes → Program → Outputs

Inputs — media sources: local files, network streams, web pages, yt-dlp URLs, cameras, test patterns.

Scenes — compositor layouts combining multiple inputs. Each scene has slots with per-slot position, size, z-order, alpha, and volume controls.

Program — the currently live scene, sent to all active outputs simultaneously. Cut or crossfade between scenes.

Outputs — streaming destinations (SRT, RTMP, HLS, WebRTC, Decklink, etc.). Multiple outputs can share an encoder; dedicated encoders per output are also possible.

Features

Inputs

Type	Description
uridecodebin3	Local files and streams (HTTP, SRT, RTMP, RTSP)
playlist	Sequence of video clips and HTML pages
wpesrc	Web page rendered as video (HTML/CSS/JS overlays)
ytdlp	YouTube, Twitch, and hundreds of other sites via yt-dlp
nodecg	NodeCG broadcast graphics
v4l2src	Webcams and capture cards (V4L2)
imagesrc	Still images (PNG, JPEG, WebP, SVG)
testsrc	SMPTE color bars and test patterns
whip	Browser screen share or webcam via WebRTC (experimental)

Input Pickers (Proxies) — Configurable dropdowns in the "Add Input" dialog for fast discovery of local files, webcams, NodeCG sources, MediaMTX/OvenMedia streams, SRT relays, and playlists. Define in config.toml with [proxy.<name>] sections. See dove/docs/proxies.md.

Outputs

Type	Description
srtsink	SRT push to a remote listener
srtserversink	SRT server mode (remotes connect to DOVE)
rtmpsink	RTMP push
rtspclientsink	RTSP push
hlssink2	HLS segments (also used for previews)
splitmuxsink	Segmented file recording
decklink	SDI/HDMI via Blackmagic Design card
shout2send	Icecast/Shoutcast audio stream

Encoders

Hardware-accelerated encoding via VAAPI (AMD/Intel) or Vulkan Video. Software fallback via x264 / x265. Set video_encoder.name = "auto" to pick the best available encoder at startup. Multiple outputs can share a single encoder, or each output can have its own dedicated encoder. See dove/docs/encoders.md.

Encoder	Type
x264	Software (always available)
openh264	Software alternative
vah264enc / vaapih264enc	VAAPI (AMD/Intel)
vulkanh264enc	Vulkan (Mesa 26+, GStreamer 1.28+)
mpph264enc	Rockchip hardware

Audio & Video Filters

Per-input dynamic filter chains, applied at runtime without pipeline restart.

Audio: highpass, lowpass, 3-band/10-band EQ, compressor (LSP), expander (LSP), gate (LSP), limiter, amplify, pan, invert, echo, denoise, loudnorm. See dove/docs/audio-filters.md.

Video: color balance, flip/mirror, crop, color effects, blur, chroma key. Experimental (requires frei0r-plugins): pixelate, cartoon, glow, vignette, film grain, glitch, scanlines, sobel edge, color halftone. See dove/docs/video-filters.md.

Previews

• WebRTC — sub-second latency preview in the browser.
• HLS — works in restricted networks, through any reverse proxy over HTTPS.

Keyboard Shortcuts

Full keyboard control for live production: scene selection (1–9), cut/crossfade (Enter), transition toggle (T), and more. Press ? in the UI for the full list. See dove/docs/keyboard-shortcuts.md.

Quick Start

Want a ready-to-run setup with example inputs and scenes? See dove-demo for a pre-configured docker-compose stack you can spin up in one command.

To install DOVE from scratch:

Docker Compose

git clone https://github.com/dorftv/dove.git && cd dove
cp config-example.toml config.toml

Software rendering (no GPU):

docker compose up

AMD GPU (VAAPI + Vulkan):

docker compose -f docker-compose.yml -f docker-compose.amd.yml up

Intel GPU (VAAPI + Vulkan):

docker compose -f docker-compose.yml -f docker-compose.intel.yml up

Open http://localhost:5000

Configuration

Copy config-example.toml to config.toml and edit as needed. See dove/docs/config.md for all options.

[main]
default_resolution = "HD720"    # QHD, FullHD, HD720, nHD, …
default_framerate = "30/1"
volume = 0.7

[preview.scenes]
type = ["webrtcbin", "hlssink2"]
video_encoder.name = "auto"

Authentication

Optional OIDC authentication (Keycloak, Authentik, Authelia, etc.). Disabled by default — enable with:

[auth]
enabled = true
issuer = "https://auth.example.com/realms/dove"
client_id = "dove-app"
client_secret = "your-secret"

Four roles: User, Supervisor, Outputs, Admin. See dove/docs/auth.md for setup, role details, API tokens, and nginx integration.

Documentation

In-app help is available at /help after starting DOVE. All docs are in the dove/docs/ directory:

Setup — Interface overview · Configuration · Authentication

Pipeline — Inputs (uridecodebin3 · playlist · wpesrc · ytdlp · nodecg · testsrc · screencast) · Input Pickers · Scenes · Outputs · Encoders

Effects & Output — Audio filters · Video filters · Previews

Operations — Debugging · Connection Status

Tech Stack

• GStreamer 1.26+
• FastAPI + uvicorn — REST API and WebSocket
• Nuxt 4 — web frontend
• Python 3.12 or 3.13

Note: Python 3.14 is not supported for native installs due to PyGObject/GStreamer thread interaction bugs. Use Python 3.12 or 3.13. Docker images are pinned to 3.12 and unaffected.

Development

Running DOVE natively from a Python venv: see dove/docs/install.md.

Contributing

Contributions are welcome! Please open an issue first to discuss larger changes. For bug reports, include the GStreamer version, config, and relevant logs.

Notes

• Decklink requires a supported Blackmagic Design card and the decklink GStreamer plugin
• WebRTC previews use announced_ip for the server's public IP — set in config.toml or via ANNOUNCED_IP env var
