Using command line, there are various ways to convert image to video. You can use those command in java for saving. You can get those commands from the following link:

1. Using ffmpeg to convert a set of images into a video
2. Create a video slideshow from images

I am sharing a code snippet to solve the issue:

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);
    }
}

Code for creating image from video

String filePath = "D:\\temp\\some.mpg";
String outdir = "output";
File file = new File(outdir);
file.mkdirs();
Map m = System.getenv();

/*
 * String command[] =
 * {"D:\\ffmpeg-win32-static\\bin\\ffmpeg","-i",filePath
 * ,"-r 30","-f","image2",outdir,"\\user%03d.jpg"};
 * 
 * ProcessBuilder pb = new ProcessBuilder(command); pb.start();
 */
String commands = "D:\\ffmpeg-win32-static\\bin\\ffmpeg -i " + filePath
        + " -r 30  -f image2 " + outdir + "\\image%5d.png";
Process p = Runtime.getRuntime().exec(commands);

code for creating video from image

String filePath = "output";
File fileP = new File(filePath);
String commands = "D:\\ffmpeg-win32-static\\bin\\ffmpeg -f image2 -i "
        + fileP + "\\image%5d.png " + fileP + "\\video.mp4";
System.out.println(commands);
Runtime.getRuntime().exec(commands);
System.out.println(fileP.getAbsolutePath());

Another approach for Android developers:

1. Create a temporary folder inside the Android.
2. Copy your images in the new folder
3. First, rename your pictures to follow a numerical sequence. For example, img1.jpg, img2.jpg, img3.jpg,... Then you may run:
4. Run this program programmetcally ffmpeg -f image2 -i img%d.jpg /tmp/a.mpg To run this programmatically,

Use the following code:

void convertImg_to_vid()
{
    Process chperm;
    try {
        chperm=Runtime.getRuntime().exec("su");
          DataOutputStream os = 
              new DataOutputStream(chperm.getOutputStream());

              os.writeBytes("ffmpeg -f image2 -i img%d.jpg /tmp/a.mpg\n");
              os.flush();

              chperm.waitFor();

    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (InterruptedException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }
}
