Transcode Adobe Media Encoder live stream using FFMPEG in node.js
23 juin 2014, par user2757842I am using Adobe media live encoder to send a stream up to the adobe media server. What I would like to do is take that stream and transcode it to a local file on my machine in another format other that .f4m
Here is the code I have so far, it is built using FFmpeg within a node.js app :
var ffmpeg = require('fluent-ffmpeg');
var fs = require('fs');
//make sure you set the correct path to your video file
var inStream = fs.createReadStream('rtmp://localhost/livepkgr/livestream live=1'); // this is where the streams are stored
var command = new ffmpeg({ source: inStream});
//Set the path to where FFmpeg is installed
command.setFfmpegPath("C:\\Users\\Jay\\Documents\\FFMPEG\\bin\\ffmpeg.exe");
command
//set the size
.withSize('100%')
// set fps
.withFps(24)
// set output format to force
.toFormat('ismv')
// setup event handlers
.on('end', function() {
console.log('file has been converted successfully');
})
.on('error', function(err) {
console.log('an error happened: ' + err.message);
})
// save to file <-- the new file I want -->
.saveToFile('rtmp://localhost/livepkgr/livestream1'); //this is where i want to store the newly converted streamI have it working with a local file but when I try it with my live stream, I get this error
events.js:72
throw er; // Unhandled 'error' event
^
Error: ENOENT, open 'C:\Users\Jay\workspace\FFMPEGtest\rtmp:\localhost\livepkgr\livestream live=1'Anyone seen this before ?

My media converter app crashes when handling file names with spaces
24 mars 2014, par suffaI wrote an app that uses ffmpeg to convert media files (.wav, .avi, .mp3, ... etc.). It works only with file names that have no spaces. When a file name with spaces is encountered, the app immediately closes. Can someone tell me if the string I'm using to call ffmpeg is correct, or need some characters escaped ? Below is a fragment of the code :
