    I am creating video editing application using JavaScript, ffmpeg and java. Using FFMPEG i have created extract n frame of video, than using canvas.toDataUrl I am replacing new image with existing image frame rate and everything has taken care, but when I use these image to create video, FFMPEG never include newly created PNG image.

    code to save png image from HTML5 canvas

    Base64 decoder = new Base64();
    
    byte[] pic = decoder.decodeBase64(request.getParameter("pic"));
    
    String frameCount = request.getParameter("frame");
    
    InputStream in = new ByteArrayInputStream(pic);
    
    BufferedImage bImageFromConvert = ImageIO.read(in);
    
    String outdir = "output\\"+frameCount;
    
    //Random rand = new Random();
    
    File file = new File(outdir);
    
    if(file.isFile()){
    
        if(file.delete()){
    
            File writefile = new File(outdir);
    
            ImageIO.write(bImageFromConvert, "png", file);
    
        }
    
    }
