please check , if you can do it in javascript

document.getElementByTagName("video") or get the video object and try .duration

var duration = document.getElementByTagName("video").duration;

and then covert to Time format.

 

 

or you can read the Video Resource Properties like below :

Retrieve the xmpDM:value and xmpDM:scale properties from the video asset's metadata and the calculate the duration

 

public static String calculateVideoDuration(Resource videoResource) {
    ValueMap properties = videoResource.getValueMap();
    double value = properties.get("xmpDM:value", Double.class);
    double scale = properties.get("xmpDM:scale", Double.class);

    double durationInSeconds = value / scale;

    int hours = (int) (durationInSeconds / 3600);
    int minutes = (int) ((durationInSeconds % 3600) / 60);
    int seconds = (int) (durationInSeconds % 60);
    return String.format("%02d:%02d:%02d", hours, minutes, seconds);
}
