API based Online Video Editor

NodeJs, AngularJs & FFMPEG based web video editor. I have showing the backend logic for editing video. Actually when someone try to edit video using NodeJs, ffmpeg, he cant think how to start & how he can do it. So I have implemented this video editor with very simple logic with ffmpeg. All resource are together here & anybody can start from here. If someone analysis these codes, he can understand the basic for video editor

Feature Implemented :

Mute a Video
Remove Video & save Only audio.
Showing Video Metadata.
Genarate Thumbnail.
Cropping Video
Effect : Fadein, Fadeout,Blur, Sharpen.

Working on :

Watermark
More Video Effects
Add new sound
Add Text

Configure mechine: ( Linux )

1. SSH into your instance and become root
sudo su -

2. Go to the the /usr/local/bin directory
cd /usr/local/bin

3. Inside the /usr/local/bin directory, create an "ffmpeg" directory
mkdir ffmpeg

4. Go into the new directory
cd ffmpeg

5. Go to static build directory at http://ffmpeg.gusari.org/static/64bit/ and pick the 
latest version of FFMPEG - as of this writing, it was ffmpeg.static.64bit.2014-02-16.tar.gz
wget http://ffmpeg.gusari.org/static/64bit/ffmpeg.static.64bit.2014-02-16.tar.gz

6. The file should now be in /usr/local/bin/ffmpeg. Untar it...
tar -xzf ffmpeg.static.64bit.2014-02-16.tar.gz

5. Run it and check what the latest version is 
./ffmpeg -version
6. If you want to be able to execute FFMPEG from any directory, simply create a symlink into /usr/bin like this:
ln -s /usr/local/bin/ffmpeg/ffmpeg /usr/bin/ffmpeg
ln -s /usr/local/bin/ffmpeg/ffprobe /usr/bin/ffprobe

The first part (/usr/local/bin/ffmpeg/ffmpeg) is where the file is located after I untarred 
the file. The second part (/usr/bin/ffmpeg) is where we want the symlink to go

Configure mechine: ( Mac )

$ brew install ffmpeg --force
$ brew link ffmpeg

How ffmpeg, NodeJs works:

Mute Video : To disable audio you can use noAudio( ) method.

    ffmpeg('public/raw/test.mp4') //Input Video File
    .output('public/edited/noaudio/output.mp4') // Output File
    .noAudio().videoCodec('copy')
    .on('end', function(err) {
        if(!err)
        {
            console.log("Conversion Done");
        }

    });
    .on('error', function(err){
        console.log('error: ', +err);

    }).run();

Remove Video & save Only audio :

    ffmpeg('public/raw/test.mp4')  // Input Video File
    .output('public/edited/removevideo/output.mp3') // Output  File
    .on('end', function(err) {
        if(!err)
        {
        	console.log("Remove video is done");
        }

    })
    .on('error', function(err){
        console.log('error: '+err);
    }).run();

Showing Video Metadata:

ffmpeg.ffprobe('public/raw/test.mp4', function(err, metadata) { // Input video File
   if(err){
    console.log("MetaData not Found. "+err);
   }
   else{
    console.log(metadata)
   }
});

Genarate Thumbnail:

    var ffmpeg = require('fluent-ffmpeg'); 
    var probe = require('node-ffprobe');
    probe('public/raw/test.mp4', function(err, probeData) 
    {

        var proc = new ffmpeg('public/raw/test.mp4'); // Input File

        proc.screenshots({
            timestamps: ['50%','80%'],
            folder: 'public/edited/thumbnail/output', // Thumbnail Location
            size: '392x220'
        }).on('end', function() {
           console.log('Screenshots taken');
        });

    });

Cropping Video:

    ffmpeg('public/raw/input.mp4') //Input Video File
    .output('public/edited/cropvideo/output.mp4') // Output File
    .audioCodec('libmp3lame') // Audio Codec
    .videoCodec('libx264')  // Video Codec
    .setStartTime(03) // Start Position
    .setDuration(5) // Duration
    .on('end', function(err) {
        if(!err)
        {

            console.log("Conversion Done");
            res.send('Video Cropping Done');

        }

    })
    .on('error', function(err){
        console.log('error: ', +err);

    }).run();
