• How to take thumbnail image from video bytes[] using java ?

  14 mai 2021, par Sreeraj S

  My requirement is, i want to show video thumbnail in fancybox. But unfortunatly its not showing thumbnail. its required seperate image for thumbnail.

  


  Sample fancybox code

  


  <a data-fancybox="data-fancybox" data-type="iframe" data-width="640" data-height="360" href="http://download.blender.org/peach/bigbuckbunny_movies/BigBuckBunny_320x180.mp4">&#xA;    <img class='card-img-top img-fluid' src="local/cache-vignettes/L300xH169/bird1jpg-6986985-13aa4.jpg?1620994482" width='300' height='169' />&#xA;</a>&#xA;

  


  So i decided to maintain two url

  


  one for video and other for video thumbnail.

  


  

  1. http://localhost:8080/resources?resourceId=126 -> it will return video

  


  2. http://localhost:8080/resources?resourceId=126&thumbnail=true -> it will return thumbnail image

  


  


  I haven't any idea about this but I had tried for video thumbnail with https://github.com/bytedeco/javacv. But i got 'OutofMemory' exception

  


  pom.xml

  


  <dependency>&#xA;    <groupid>org.bytedeco</groupid>&#xA;    <artifactid>javacv-platform</artifactid>&#xA;    <version>1.5.5</version>&#xA;  </dependency>&#xA;

  


  My java servlet code for thumbnail image is as follows

  


  Java2DFrameConverter converter = new Java2DFrameConverter();
BufferedImage current;
BufferedImage next;
byte[] videoBytes = //video byte array fetched from db
ByteArrayOutputStream baos = new ByteArrayOutputStream();

FFmpegFrameGrabber frameGrabber = new FFmpegFrameGrabber(new ByteArrayInputStream(videoBytes));
frameGrabber.start();
try {
    Frame frame = frameGrabber.grab();
    next = converter.convert(frame);

    current = new BufferedImage(next.getWidth(), next.getHeight(), next.getType());
    ImageIO.write(current, "png", baos);
    byte[] bytes = baos.toByteArray();
    frameGrabber.stop();


    response.setContentType("image/png");
    try (OutputStream o = response.getOutputStream()) {
        o.write(bytes);
        o.flush();
    }


  


  Edit

  


  Video section is working fine. i.e. can able to view video from this url http://localhost:8080/resources?resourceId=126
