• Save base64 bit encoded tring to the file in php

  10 mai 2016, par ppeiris

  I have a php application which takes base64 encoded wav file from the client (browser) via ajax and save to the database. No I have to re encode the wav file using ffmpeg before I save the file in to the database (I can do this using system calls). But the questions is I need the input file (name.wav) for ffmpeg to do the work and as of right now I have only base64 encoded string in my php variable. I need to save this file to the disk using these base64 encoded string. How can I do this in php.

  my server is running on RedHat and apache.

  Thanks for your help in advance

• Save video to disk from WebRTC MediaStream in Node

  27 novembre 2020, par SAGBO Aimé

  I'm building an app where the user can connect to the server through a WebRTC (I'm using simple-peer library both server-side and client-side to set the peer-to-peer connection).
Once the client and the server are connected, the client app stream the user camera and micro to the server.

  


  Now, I want to save the streamed data to the filesystem server-side as an MP4 video file.

  


  I hear about ffmpeg and fluent-ffmpeg to achieve this but i don't know how to use them.

  


  

  • Server side code to set up the peer connection

  


  


  const Peer = require("simple-peer");
const wrtc = require("wrtc");

const peer = new Peer({ initiator: false, wrtc: wrtc, trickle: false });

peer.on("error", (err: any) => console.log("error", err));

  peer.on("signal", (data: any) => {
    if (data.type === "offer" || data.type === "answer")
      dispatchMessage(JSON.stringify(data));
    // if (data.renegotiate || data.transceiverRequest) return;
  });

  peer.on("connect", () => {
    console.log("CONNECTED");
    peer.send(JSON.stringify("HELLO DEER PEER FROM SERVER"));
  });

  peer.on("data", (data: any) => {
    console.log("data: ", data);
  });

  peer.on("stream", (stream: MediaStream) => {
    console.log("-------Stream received", stream);
  });

  peer.on("track", (track: MediaStreamTrack) => {
    console.log("-------trackEvent:", track);
  });


  


  

  • Client-side code

  


  


  const stream = await window.navigator.mediaDevices.getUserMedia({
    video: { width: { ideal: 4096 }, height: { ideal: 2160 }},
    audio: true,
});

const p = new SimplePeer({
    initiator: isInitiator,  
    trickle: false  
});

stream.getTracks().forEach(track => p.addTrack(
    track,  
    stream  
));

// Here I set up the listeners for the peer connection
