ffmpegwasm/ffmpeg.wasm

Features

• Media Transcoders - Converts audio and video files directly in the browser to avoid server-side infrastructure.
• WebAssembly Frameworks - Runs the multimedia processing engine directly in the browser to transcode and manipulate media files locally.
• Transcoding Engines - Converts audio and video formats and applies visual filters directly within the browser using a high-performance engine.
• Client-Side Media Processing - Performs resource-intensive audio and video manipulation tasks locally within the browser.
• Client-Side Media Processors - Executes resource-intensive audio and video tasks in background threads to maintain a responsive user interface.
• Virtualized Filesystem Layers - Maps browser memory to a simulated file system for efficient input and output handling without disk access.
• Background Processing Workers - Delegates heavy computational workloads to background threads to maintain main user interface responsiveness.
• Browser-Based Recorders - Captures live audio and video streams from browser sources and encodes them into files for local storage.
• Media Stream Processing - Captures audio and video input from browser sources and encodes the data into files for local storage.
• WebAssembly - Executes compiled C code in the browser at near-native speeds using a sandboxed virtual machine.
• In-Memory File Systems - Manages media data operations through an isolated, in-memory virtual file system.
• Shared Memory Data Exchange - Enables high-performance data exchange between threads using shared memory buffers to avoid expensive copying.
• Virtual File Systems - Populates and retrieves media files from an isolated in-memory file system for efficient processing.
