MediaPlayer.MediaStateChanged += HandleStateChange; should raise events when a song loops

[vchelaru]

MediaStatePlayer.MediaStateChanged event should raise whenever a song loops. For example, the following code could be used:

MediaPlayer.MediaStateChanged += HandleStateChange;
...
private void HandleStateChange(object sender, EventArgs e)
{
    System.Diagnostics.Debug.WriteLine($"State change at {DateTime.Now} to {MediaPlayer.State}");
}

When running on a MonoGame DesktopGL project, this happens when it loops:

State change at 1/11/2025 9:39:22 AM to Stopped
State change at 1/11/2025 9:39:22 AM to Playing

On Blazor GL projects the events are not raised.

This is important because this can be used to detect when a song loops.

What version of KNI does the bug occur on:

• KNI 3.14

What operating system are you using:

• Windows11

What KNI platform are you using:

• BlazorGL

When HTMLMediaElement is set to loop = true, I didn't get any events when the loop restarts.
We could fake the loop, and restart the song manually when the song is finished, but that will introduce a gap between the loops.
or we could perhaps use the timeupdate event and currentTime property to detect a restart.

There is also the SongFinishedPlaying event, which I have to check if it's working in looped songs.
