UAVideo Player supports Bookmark navigation. This means that you can create a Bookmark index for specific timestamp inside a media segment and later seek to it using the Timeline control. Bookmark is a locally stored marker that represents the position inside a file. You can later use the bookmarks for easy and quick access to specified location in the file. Creating bookmarks is relatively straight forward. Seek to a required position and press a Bookmark button. This will Open a Bookmark Dialog add set the current position into the bookmark list.

Figure 1. Creating Bookmarks.

You can set bookmark Name and Description and select the bookmark color. A KeyFrame for the bookmark will be created automatically.

Note: The Start time for the bookmark will be set when you open the dialog. You can also select "Set Duration On Close" option. In this case your bookmark will have the duration attribute.

You can navigate inside a file using bookmarks by opening a Timeline window.
