I stored videos in hard disk and stored their link in database, as I find this as a solution to stored video in database. Now I need retrieve thumbnail image of each video.so how can I get thumbnail image of video (MJPEG format) using ffmpeg in java..
I don't know maybe I cannot find the right keywords.
PS: I am using Eclipse IDE and implement required interface in Java Swing
You can use xuggle which it is easy to use and has samples to do so.
However, it is deprecated. You may like to check humble video instead.
I have used xuggle and it supports a huge list of video formats.
It works on major operation systems without installing anything.
Search google for it.
Here you can find the library and sample codes. However, it depends on you on which frame you want to take the thumbnail.
Play with this code to find your needs:
