Feature Description
Introduce a background processing system for video export by leveraging Web Workers to offload FFmpeg.wasm operations from the main thread. This will ensure a smooth, responsive user interface even during heavy video processing tasks.
Problem this Solves
Currently, the application performs video export directly on the main thread using FFmpeg.wasm. This leads to:
UI freezing during export operations
Browser tab becoming unresponsive for large or complex files
Degraded user experience, especially on low-end devices
This limitation significantly impacts usability and scalability of the application.
Proposed Solution
Implement a multi-threaded export mechanism using Web Workers:
Move FFmpeg processing logic into a dedicated Web Worker
Use postMessage() API for communication between main thread and worker
Send video data and export configurations to the worker
Receive real-time progress updates and completion signals
Enhancements to include:
📊 Real-time progress indicator
🔄 Export status updates (Processing / Completed / Failed)
❌ Option to cancel ongoing export
⚠️ Robust error handling and fallback mechanisms
Alternatives Considered
Main-thread optimization: Limited impact; UI blocking persists
Reducing processing complexity: Does not eliminate freezing
Server-side processing: Adds backend overhead, latency, and infrastructure dependency
Compared to these, Web Workers provide a scalable and efficient client-side solution.
Additional Context
This feature directly addresses existing performance-related issues (e.g., browser freezing during export) and aligns with improving responsiveness and user experience across the platform.
Implementing this will:
Enhance performance and scalability
Improve reliability of export functionality
Potentially resolve multiple open performance-related issues
Suggested Labels
enhancement feature performance refactor
Request
I would like to work on this feature. Kindly assign this issue to me.
If you want to go even stronger 🔥
I can also give you:
exact folder structure
worker.js + main thread code
how to integrate FFmpeg.wasm properly
Just say 👍
