  • Trying to load a video file with ffmpeg using javacv

    11 mars 2012, par Takatakas

    I am trying to load a video file with javacv but I am facing some problems.

    I managed to compile an application that will show an image on screen so I assume that my setup is ok.

    The code I am using is the following.

    import java.io.File;
    

    
import com.googlecode.javacv.CanvasFrame;
    
import com.googlecode.javacv.FFmpegFrameGrabber;
    

    
public class TestCV{
    

    
    public static void main(String[] args) throws Exception {
    

    
        File f = new File("input.mp4");
    
        FFmpegFrameGrabber grabber = new FFmpegFrameGrabber(f);
    

    
        final CanvasFrame canvas = new CanvasFrame("My Image");
    

    
        canvas.showImage(grabber.grab());
    

    
    }
    
}

    Here is the error

    Do I have to use separate ffmpeg dlls ? There is one ffmpeg dll in the opecv bin folder.

    If I have to do this I will need a better way to include them using eclipse. Until now I just add the folder to path variable. For example I added this to make opencv work.

    C :\opencv\build\common\tbb\ia32\vc10~;C :\opencv\build\x86\vc10\bin~;

  • How do I programmatically create video from vector graphics ?

    22 mars 2012, par numan salati

    I have a bunch of vector graphics commands (lines, shapes and paths with timing info) and some images and audio files that I would like to encode into some video format like flv, mp4, avi

    Is there a tool that can help with do that - either programmatically or one that can be scripted ?

    Some background - I've a drawing tool in android where I want to save the resulting animation of the drawing into a video format to publish to vimeo/youtube. I can retrieve each stroke info (with timing) but I am not sure how to covert it into a video format.
