Infs.addInput('./data/test3.mp4').outputOptions([ pitch-detector: pitch detector implemented using RTCAudioSink and RTCDataChannel. ping-pong: simple RTCDataChannel ping/pong example. audio-video-loopback: relays incoming audio and video using RTCRtpTransceivers. It is necessary to make sure you have those files served there.I'm programming a tool for convert MP4 to HLS with nodejs, I'm trying to use fluent-ffmpeg to convert it, but I have some error at giving "outputOptions". This project presents a few example applications using node-webrtc. When calling ffmpeg.load(), by default it looks for to download essential files (ffmpeg-core.js, ffmpeg-core.wasm, ). Why it doesn't work in my local environment?
To build on your own, you can check build.sh inside repository.Īlso you can check this series of posts to learn more fundamental concepts: In fact, it is ffmpeg.wasm-core most people would like to build. Yes, but only for Firefox 79+ with proper header in both client and server, visit to try whether your Firefox works.įor more details: What is the maximum size of input file?Ģ GB, which is a hard limit in WebAssembly. It is a small code base and under MIT license. ( contains WebAssembly code which is transpiled from original FFmpeg C code with minor modifications, but overall it still following the same licenses as FFmpeg and its external libraries (as each external libraries might have its own contains kind of a wrapper to handle the complexity of loading core and calling low-level APIs.You probably know it can run from the terminal, but did you know it can also be invoked from an application in Node. There are two components inside ffmpeg.wasm: FFmpeg is a versatile open-source tool for encoding video files and performing basic editing operations such as stitching, cropping, and resizing. Need to pass -row-mt 1, but can only use one thread to help, can speed up around 30% Documentation Run it multi-threading mode by default, no need to pass any arguments. From the FFmpeg website: It contains libavcodec, libavutil, libavformat, libavfilter, libavdevice, libswscale and libswresample which can be used by applications.
Multi-threading need to be configured per external libraries, only following libraries supports it now: x264 Const ffmpeg = createFFmpeg ( ) Multi-threading
