wrtc-to-ffmpeg
Pipe MediaStreamTracks between wrtc and fluent-ffmpeg. Early development, plenty of issues. Currently only for Unix and Linux.
Allows you to record WebRTC streams, stream media files over WebRTC connections, or route WebRTC streams to RTSP/RTMP/etc.
const ffmpeg = require('fluent-ffmpeg')
const wrtc = require('wrtc')
const w2f = require('wrtc-to-ffmpeg')(wrtc)
const input = await w2f.input(track) // audio or video MediaStreamTrack
ffmpeg()
.input(input.url) // add our input
.inputOptions(input.options) // specify the input options
.output('./myVideo.mp4') // save the stream to an mp4
You can also pipe FFMPEG output to MediaStreamTracks
.
const videoOutput = await w2f.output({ kind: 'video', width: 480, height: 360 })
const audioOutput = await w2f.output({ kind: 'audio', sampleRate: 48000 })
ffmpeg()
.input('./myVideo.mp4')
.output(videoOutput.url)
.outputOptions(videoOutput.options)
.output(audioOutput.url)
.outputOptions(audioOutput.options)
videoOutput.track // do what you want with the new MediaStreamTracks
audioOutput.track
API
input = await w2f.input(track)
Transforms a MediaStreamTrack
into an input object.
input.url
is a Unix domain socket path that FFMPEG can use as input.
input.options
is an object with the minimum FFMPEG options.
output = await w2f.output({ kind, width, height, sampleRate })
Creates an output object with the specified properties.
output.track
is a MediaStreamTrack
.
output.url
is a Unix domain socket path that FFMPEG can use as output.
output.options
is an object with the minimum FFMPEG options.
