Xuggler, going straight to a certain frame (second) without reading the whole video

Question

In this example is for capturing images from a video with Xuggler, the Java video library, it's for periodically capturing frames from a video into images.

https://www.javacodegeeks.com/2011/02/xuggler-tutorial-frames-capture-video.html

In it I see that we’re creating a media reader and reading the video until the time we capture the image. can this process be speeded up, for example by jumping to a certain frame, without having to read all the frames? starting to only “play” the video near the capture time? Does Xuggler support that (jumping to a certain certain frame at a certain second?)
