https://github.com/zhaohappy/libmediaA high-performance multimedia processing library for the Web using a hybrid TypeScript and WebAssembly architecture. It provides FFmpeg-like APIs for muxing, demuxing, encoding, decoding, and rendering. Key modules include avcodec (Wasm and WebCodecs), avformat, avrender (WebGL/WebGPU), and avnetwork (Fetch, WebSocket, WebTransport). It supports various formats like MP4, FLV, and Matroska, and protocols including HLS, DASH, RTMP, and RTSP.
@libmedia/avtranscoder package provides an implementation of a media transcoder within the libmedia ecosystem. It is designed to handle media transcoding tasks by leveraging the underlying libmedia infrastructure.@libmedia/avplayer package provides a UI-enabled implementation of the libmedia player. It is designed for users who need a media player that includes built-in user interface components rather than just low-level playback logic.avutil package is a utility library within the libmedia ecosystem. It provides helper functions and tools designed to support media processing tasks across the various libmedia modules.libmedia is a multimedia processing library designed for Web platforms. It enables handling of audio, video, and subtitles directly in the client environment.
Key capabilities include:
@libmedia/audiostretchpitch package provides audio time-stretching (changing speed without changing pitch) and pitch-shifting (changing pitch without changing speed) capabilities. It is powered by a compilation of the soundtouch library.videoscale package provides capabilities for video scaling and format conversion. It is built upon the FFmpeg libswscale module.avpipeline package is a media task processing pipeline designed for multi-threaded parallel task processing. It is used to manage and execute media-related tasks across multiple threads to improve performance and throughput.The @libmedia/avcodec package is an audio/video codec library. It provides access to codecs through two primary implementations:
This package allows developers to handle media encoding and decoding tasks in web environments using either highly compatible software codecs (via Wasm) or native browser capabilities (via WebCodecs).
@libmedia/audioresample package provides audio resampling capabilities. It is built upon the FFmpeg audio resampling module. Use this package when you need to change the sampling rate of an audio stream.The @libmedia/avrender package provides high-performance audio and video rendering capabilities. It supports various bit depths and high dynamic range formats, as well as modern web-based rendering technologies.
Supported features include:
audioWorklet support for low-latency audio processing.The @libmedia/avnetwork package provides network-related file I/O capabilities for the libmedia Web platform. It is designed to handle various data transport and file access methods required for media processing in a web environment.
Supported I/O mechanisms include:
@libmedia/avprotocol package provides implementations and abstractions for various audio and video protocols within the libmedia ecosystem. It is designed to handle the networking and protocol-specific logic required for media streaming and transport.
