  • FFMPEG extract h264 video (can't see video)

    28 décembre 2015, par Marco Ronchi

    I’m trying to extract a portion of video from another video with FFMPEG. I use this command line :

    ffmpeg -i C:\Temp\test.avi -ss 00:00:30.0 -c copy -t 00:00:10.0 C:\Temp\out.avi

    and this is the output messages :

  • How to pipe sequence of thumbnails/screenshots from ffmpeg to nodejs for further processing ?

    30 décembre 2015, par Dmitry Ivanov

    What I want to achieve is to take screenshots continuously and pass them to nodejs application in order to process each one separately and do some other stuff. I need this for Linux environment only. I picked ffmpeg with x11grab as a screenshots provider. The following command works just fine :

    ffmpeg -t 10 -s 1366x768 -f x11grab -i :0.0+0,0 -vf fps=30 output_%d.png -y

    It creates 300 consequent frames of my screen during 10 seconds period. Then I want to redirect the output to my nodejs app rather than just to write files on the hard drive. So I’m calling ffmpeg from node :

    var spawn = require('child_process').spawn,
    
    fps = 30,
    
    duration = 10,
    
    screenSize = {w: 1366, h: 768},
    
    args = [
    
        '-t', 
    
        duration, 
    
        '-s', 
    
        screenSize.w + 'x' + screenSize.h, 
    
        '-f', 
    
        'x11grab', 
    
        '-i', 
    
        ':0.0', 
    
        '-vf',
    
        'fps=' + fps,
    
        '-f',
    
        'mjpeg',
    
        'pipe:1'
    
    ],
    
    ff = spawn('ffmpeg', args);
    

    
ff.stdout.on('data', function (data) {
    
    console.log('Data size: ' + data.length);
    
});
    

    
ff.stdout.on('end', function (data) {
    
    console.log('Stream end');
    
});
    

    
ff.stderr.on('data', function (data) {
    
    console.log('ff error: ' + data);
    
});

    I apologize for a long log, but it’s important :

Stream end

    The error messages are weird too, but not the biggest problem for now, so let’s omit them.

    Looking at all the data coming from ffmpeg I assume that the images are coming as a single stream without any separation. I don’t think that looking into binary data and seeking for certain flag bytes is a good idea to solve the problem and separate the images. The command line I mentioned in the top of the post does separate writes to hard drive that means it produces separate writable streams per each screenshot. And it doesn’t do so for a spawned process from nodejs.

    What am I missing ?
