In this tutorial, I will show you how we can create thumbnail images using Java. Thumbnails are the reduced size of images or videos. Basically, if your website is loading a lot of images with larger pixel values i.e larger size then, the performance of the website will be poor.
Making a video thumbnail is relatively straightforward. You can take a screenshot from your video that best explains its contents, or you can use a tool like Photoshop or Canva to overlay text or icons on the image. To make a screen capture on a PC, use the Windows Snipping Tool.
Many of the application are using the Glide library for loading the Image and Video thumbnail. You can download the Glide Library from here and alternatively, you can include the library directly in your app using Gradle.
Well, since you're not stuck with JMF, have you considered Xuggler? Xuggler is a Java API that uses FFmpeg under the covers to do all video decoding and encoding. It's free and LGPL licensed.
In fact, we have a tutorial that shows How to Make Thumbnails of an Existing File
