Cross-Platform (Win / Linux / macOS) Portable Application
19/09/2024 This is a BETA release. Tested on Win & Linux. All main features there. No python installation required. Can run with GUI (made with NiceGUI) or without so act as service. Portable version give you flexibility and nothing installed into your OS.
WLEDVideoSync is a tool designed to synchronize WLED-controlled LED strips with video content. This project enables users to create immersive lighting experiences that complement their video playback.
Key Features:
- Video synchronization with DDP devices e.g: WLED-controlled LED strips
- Multicast feature: aggregate multi DDP devices to a big, BIG one
- Support for various video sources: image, video or WebUrl (even Youtube)
- Support for desktop / desktop area, window content
- Customizable LED effects
- API to integrate with third party application
- Websocket for image cast if necessary
- GUI: native, browser: can be accessed remotely, or even "headless": can be used as service
Portable Installation:
- Take the app from releases (Unix/ Mac/ Win)
- --> On Mac/Linux: chmod +x WLEDVideoSync
- Execute it to extract the standalone version
- Go to ./WLEDVideoSync folder and run WLEDVideoSync-{OS} app.

Manual Installation:
- Clone the repository from GitHub
- Install required dependencies : pip install -r requirements.txt
- --> on Mac/linux : pip3 install -r requirements.txt
- Run it with : python -m WLEDVideoSync
- --> on Mac/linux : python3 -m WLEDVideoSync
Usage:
- Connect your WLED-controlled LED strips
- Launch the WLEDVideoSync application
- Select your video source
- Configure LED mapping and effects
- Start the synchronization
Configuration Options:
- LED strip layout, 2D Matrix
- Color mapping
- Effect intensity
- Synchronization delay
Troubleshooting:
- Ensure your WLED device is properly connected and configured
- Check network connectivity between the application and WLED
- For optimal performance, be sure to be on the same VLAN as your DDP devices

Double-click on it to extract WLEDVideoSync folder
-
Once extraction finished, you should see this screen:
WLEDVideoSync folder can be copied, moved where you want, so keep organized
-
-
Go into and click on
WLEDVideoSync-{OS}(exe/bin) to execute the main program.- If you are on Win system, this should open "native" windows
- On Mac/Linux, you should see the app into your default browser
All of this could be configured later, for the moment focus on default.
- MANAGE:
- Screen to manage running DESKTOP / MEDIA Casts. From here you will be able to see all running casts spilt by type.
- available actions: Cancel cast, to stop this cast
Snapshot, take a picture from running cast. Image will be stored into cast BUFFER
Stop Preview, close preview window
Start Preview, open preview window
Change IP address, stream to a different DDP device and if set to 127.0.0.1: suspend stream
Multicast effects, modify cast devices order in circular, reverse or random way
- DESKTOP PARAMS:
- Manage DESKTOP parameters. Screen to manage DESKTOP parameters, see images into BUFFER and MULTICAST information.
- Params info:
FPS: enter frame per second desired for the cast stream
Scale width: cast x size in pixels
Scale height: cast y size in pixels
These values should match Matrix 2D settings of your DDP device
wled: True or False, if true the DDP device act as WLED and app will try to retreive x,y values from it.
IP: ip address of the DDP device
Input: input type to cast
To cast entire desktop:
'desktop': for Win OS
':0' or ':0.0' or other ... for Linux (should be the DISPLAY env)
To cast only an area:
'area' --> see SCREENAREA
To cast a specific window content:
'win=xxxxxxxxx' where xxxxxx should be for Win the window title and for Linux window ID/or window title
Preview: True or False, if True a cast preview window will be displayed
Format: 'gdigrab' for Win and 'x11grab' for Linux when want to cast Window/Desktop
Codec: PyAV codec used, let it to 'libx264rgb' for now
Screenarea / monitor number: select monitor number and click to SCREENAREA button to make area selection
Output: give file name or rtsp, udp etc ... to stream input. For future use.-->*Protocol
format: Pyav format
Codec: Pyav codec
Capture Frame: True or False, True will capture frames from input
Number: number of frames to capture, frames will be stored under BUFFER
Multicast: True or False, if True and Matrix (x,y) = 1 then cast will stream to all IP into 'Cast Devices'
for Matrix <> 1, this will split the cast stream into multiple images to create a Big virtual Matrix
All DDP devices need to have the same 2D Matrix configuration
Matrix X: number of DDP devices on X axis
Matrix Y: number of DDP devices on Y axis
e.g. WLED matrix 16x16 : 3(x) x 2(y)
==> this require 6 devices to set into 'Cast Devices' list
(tuple of: device index(0...n) , IP address)
This will create 6 images to send and provide big image of 3x16 leds for x and 2x16 for y
Cast Devices: number and IP address of each DDP device. Number not yet managed
device order come from entry order
Protocol: ddp or other, if 'other' will use the 'Output' entry, let it to ddp for now
Main of these values can be saved into Preset to be reloaded
- MEDIA PARAMS:
- Manage MEDIA parameters: Screen to manage MEDIA parameters, see images into BUFFER and MULTICAST information.
- Params info:
FPS: enter frame per second desired for the cast stream
Scale width: cast x size in pixels
Scale height: cast y size in pixels
These values should match Matrix 2D settings of your DDP device
Input: input type to cast
- 0, 1 or ...: this will cast your capture device number (e.g: USB Webcam)
- enter full path of any of your media files, image or video
Preview: True or False, if True a cast preview window will be displayed
wled: True or False, if true the DDP device act as WLED and app will try to retreive x,y values from it.
IP: ip address of the DDP device
Capture Frame: True or False, True will capture frames from input
Number: number of frames to capture, frames will be stored under BUFFER
Seek to Frame N: start read at this position, do not work for real time media.
Multicast: True or False, if True and Matrix (x,y) = 1 then cast will stream to all IP into 'Cast Devices'
for Matrix <> 1, this will split the cast stream into multiple images to create a Big virtual Matrix
All DDP devices need to have the same 2D Matrix configuration
Matrix X: number of DDP devices on X axis
Matrix Y: number of DDP devices on Y axis
e.g. WLED matrix 16x16 : 3(x) x 2(y)
==> this require 6 devices to set into 'Cast Devices' list
(tuple of: device index(0...n) , IP address)
This will create 6 images to send and provide big image of 3x16 leds for x and 2x16 for y

- API: Redirect to API docs/endpoint.
- Video Player: provide some additional features to MEDIA casts
-
Video Preview
-
Additional Time Slider
-
Back/Forward some frames
-
VSYNC: sync cast(s) to video player time: video timer
-
TSYNC: sync cast(s) to time slider: slider timer
-
Delay before AUTO SYNC: seconds
-
AUTO SYNC: Cast will automatically sync to the last timer selected (Player or Slider)
- if more than one cast, that's the first one that take the information, totally random
- if timer come from Slider, this will make a loop of n seconds (previous param)
- if timer come from Player and the player is set to Pause, this will make a loop of n seconds (previous param)
- if timer come from Player and the player continue, this will make automatic sync every n seconds (previous param)
-
Add Delay in ms: additional time to add to All Sync action
-
Sync All: if more than one cast, this will sync them to the selected timer
-
Play/Cast: if video format managed by the player, this will initiate on same time, play and cast, otherwise only cast
-
Re-cast: number of additional time you want to cast the MEDIA, -1 for infinite, max 9999
-
Url/Path field: enter local media name or WebUrl link, even YouTube
-
Download Icon: click on it to initiate required action depend on previous Url/Path entry
-
if local path, this will set the player to it (video/image)
player had limited codec capacity, preview could not work but cast yes -
if video WebUrl, try to directly manage it by the player
-
if YouTube, this will download the video and put it into the app media/ folder
-
if this is an image, this will download it and put it into the app media/ folder
if you want to keep downloaded video/image see configuration file
-
-
YT Search: click on it to open YouTube search area, more than one possible
- just enter some keywords to search for
- once result displayed clicked on the link provided to copy it so you can paste into Url/Path field
-
Clear YT Search: will clear all YT Search area
-
- DESKTOP or MEDIA, this work on the same way, got different parameters to set and apply to the casts for custom effects
- Flip: when checked this will flip the image depend on the type value (right/left, top/bottom)
- W / H: Scale width in pixels / Scale height in pixels, the same as for DESKTOP/MEDIA PARAMS. Usually not to be changed
- if you do, the preview window content will sync to them
- gamma: change gamma value
- R G B : adjust Red/Green/Blue Colors
- saturation / brightness / contrast / sharpen : self-explanatory
- auto: when checked, this will auto adapt brightness/contrast depend on slider
- Cast Icon: Yellow, cast not allowed, Green, allowed, Red, running
- when yellow and click on it, will allow cast
- Red Icon: stop all running casts
On preview window, you will see effects in real time
All of these values can be saved into Preset to be reloaded
The main App configuration file is: WLEDVideoSync/config/WLEDVideoSync.ini
See WLEDVideoSync/config/WLEDVideoSync.readme for in-deep information.
The logging configuration file is : WLEDVideoSync/config/logging.ini. Logs can be found under log/ folder.
Default behaviour:
-
Win OS: app will start on "native" windows mode with a 'selection' window and uvicorn server on different process.
- Closing App will put it on 'systray', terminate it need to be done from :
Exit - server:xxx
- Closing App will put it on 'systray', terminate it need to be done from :
-
Mac/Linux: app will start on 'default' browser, no systray options.
- use SHUTDOWN in footer to stop application
- "native" mode has not been deeply tested on these platforms, so may provide some trouble.
endpoint : /ws e.g: 127.0.0.1:8000/ws
/ws/docs : some online documentation
Websocket has been implemented mainly to cast only image & small delay. The image need to be stored into BUFFER. Communication data use Json format for in / out.
action/type/param are required keys.
e.g: {"action":{"type":"cast_image", "param":{"image_number":0,"device_number":-1, "class_name":"Media"}}}
