How to add bookmarks for a video in WPF

Hi.
As I know, there is not such Funcionality built into the VideoPlayerControl.
You need to Create an "derived" Control of it and build in the "PART_" for the UI to have Marker´s and to handle the Events for it also.
Please get familiar with the Word "CustomControl" or at least "UserControl".
A strategy could be to try a Test Draft as a UserControl and then if needed to create a CustomControl, by Derive the VideoplayerControl and add the desired functionality.

I wanted to answer, but can´t find my old Videoplayer in "Star Trek LCARS" Style.
I needed the "Elbows" to be calculated into the Control on Creation, so i was forced to create a CustomControl (Derived from somethin I forgot...)

Also please consider how to use the "Markers". I used the "ProgressBar"-Approach for the Playtime and I had to put over that a Canvas-Control to place the Markers according to the Timespan from the Begin of the Video to the Marker.

Also be Precize with the TimeCalculation, please stay at the Marker Generation/Placement in the VideoPlayer Scale/Measure like "Frames per Second". In The UI you should only use a "Stringformat" to cut the String into Somthing like "1h:10Min:10Sec.100frames" -> "1:10:10.100".
These Markers can then be reused as Bookmarks, where te User should add Informations/Annotations to the Bookmark.

Basicaly I set TimeSpans, that are displayed as Markers, and a Bookmark-Marker is with additional Infos about the Marker. I wanted a Function to skip the Intro in Star Trek Voyager Episodes, like "Netflix" Nowadays has the "Skip Intro" button. For that You need to handle the Player "Momentum", to skip a Timespan (defined by two Markers, set by the User).

A little bit off the Topic, but to get a gripping Buzzwording about it... That´s so 90´ies
