Currently, grabbing CurrentMediaSessions creates a new ReadOnlyDictionary.
This can cause massive memory/general optimization issues for anything that calls CurrentMediaSessions.

Need to create a class to handle both an internally usable Dictionary, and an externally usable ReadOnlyDictionary. Keeping 2 dictionaries in sync should be much more efficient than creating a new dictionary every CurrentMediaSessions get.

There is no information regarding how to use this wrapper. Could you update the readme please as I'd love to use this.

Thanks for sharing this one
im trying to get playback status, other infos would be nice too
is that possible to get data on powershell

I just got acquainted with this package and I tried to make an app with the help of the example, but I had a problem skipping or stopping the media.
I noticed that currentSession is null and I don't know why.
I'm using .NET Core 3.1

Code:

private readonly MediaManager mediaManager = new MediaManager();
private MediaSession? currentSession = null;

//some code...

private async void controlerPlay_Click(object sender, EventArgs e)
        {
            var controlsInfo = currentSession?.ControlSession.GetPlaybackInfo().Controls;

            if (controlsInfo?.IsPauseEnabled == true)
            {
                await currentSession?.ControlSession.TryPauseAsync();
            }
            else if (controlsInfo?.IsPlayEnabled == true)
            {
                await currentSession?.ControlSession.TryPlayAsync();
            }
        }

        private async void ControlerNext_Click(object sender, EventArgs e)
        {
            await currentSession?.ControlSession.TrySkipNextAsync();
        }

I've been trying to create a DLL to use WindowsMediaController in Unity x64 standalone build without success. I assume this is Unity Mono issue but thought I'd ask anyway.

This was my attempt but Unity throws al sort of issues with the imported support DLLs. Maybe there is a different approach I should be taking?

Here is my minimal attempt:
`using System;
using Windows.Media.Control;
using WindowsMediaController;
using static WindowsMediaController.MediaManager;

namespace MediaTrackInfo
{
public class MediaTrack : IDisposable
{
private MediaManager mediaManager;
private string currentTrackName;

    public MediaTrack()
    {
        mediaManager = new MediaManager();

        mediaManager.OnAnyMediaPropertyChanged += MediaManager_OnAnyMediaPropertyChanged;

        mediaManager.Start();
    }

    private void MediaManager_OnAnyMediaPropertyChanged(MediaSession mediaSession, GlobalSystemMediaTransportControlsSessionMediaProperties mediaProperties)
    {
        currentTrackName = $"{mediaProperties.Artist} - {mediaProperties.Title}";
    }

    public string GetCurrentMediaTrack()
    {
        return currentTrackName;
    }

    public void Dispose()
    {
        mediaManager?.Dispose();
    }
}

}
`

Current windows targets (windows10.0.22000.0) are for windows 11, minimum windows 10 target is windows10.0.17763.0
Because of this I have to build my own dll for the plugin I'm using for Artemis (it uses windows10.0.17763.0 dlls)

Target framework versioning is confusing, yes. I also made this mistake thinking I was targeting my plugin for w10 but it was actually w11

How to run this lib through Task Scheduler?

It works perfectly if starting manually via compiled exe or calling the exe via cmd/powershell.

But in Task Scheduler Returns below error: "mediaManager.Start()"

System.Exception: The specified service does not exist as an installed service.

Hey @DubyaDude,

This is a great library, however, using it on .NET 6 gives the following error:

WindowsMediaController.dll cannot be referenced because it uses built-in support for WinRT, which is no longer supported in .NET 5 and higher. 
An updated version of the component supporting .NET 5 is needed. For more information, see https://aka.ms/netsdk1149

Do you think it would be possible to achieve this functionality without WinRT?

Thanks!

Running Spotify, then closing it after around 5/10+ seconds and after using the controls, this error gets thrown.

Hello,

I'm getting this error when trying to call Start or StartAsync on MediaManager.
System.Exception: 'Call was canceled by the message filter. (Exception from HRESULT: 0x80010002 (RPC_E_CALL_CANCELED))'

Once I was able to trigger everything right however since then every run of my app crashes with this exception. Try/Catch is not solution as it crashes every single time.

Did you experienced the same issue? Thanks a lot!

Firstly, thank you for the new event. It really cleans my code for my use case.

The problem is:
When the current focused media session is closed, new focused media session's playback state reported as "Paused"

I'm experiencing this error both in my own application, and the provided sample applications
It seems that .Dispose() on sessions modifies the keys being iterated in MediaManager.Dispose

Unhandled Exception: System.InvalidOperationException: Collection was modified; enumeration operation may not execute.

When using Chrome and YouTube (presumed to be similar on other browsers) when the video changes GetFocussedSession() is wrong as Chrome removes itself as a media source when unloading the page and re-adds itself as a media source when loading which results in an exception.

System.Collections.Generic.KeyNotFoundException: The given key 'chrome.exe' was not present in the dictionary.
   at System.Collections.Generic.Dictionary`2.get_Item(TKey key)
   at WindowsMediaController.MediaManager.GetFocusedSession(GlobalSystemMediaTransportControlsSessionManager sender)

I'd probably expect that if no focussed sessions were found, I.E, there are none present or the one trying to be found is null, it tries to default to another session or just returns a null controller.

Hello, I'm the current maintainer of Aurora-RGB and also making a plugin for Artemis-RGB. I will also reference this repository on those projects.
https://github.com/Aurora-RGB/Aurora
https://github.com/Aytackydln/Artemis.MediaInfo
https://github.com/Artemis-RGB/Artemis

Thanks for the library, RGB devices will be able to react depending on media :)

I wanted to add media muted information too but library didn't expose that. I also noticed playback information updates whenever I mute/unmute media so I thought it would be possible to add to this library.

This error comes up on some of Aurora's users. Sadly this stack trace is all I can get.

I tried the example project in the repository, I am using Windows 10 Pro 21H2 build 19044.2006.

• OnAnySessionOpened event is raised only when you launch the program, any new media source can not be detected while the program is running.
• When you close media source (spotify or chrome for example) the OnAnySessionClosed event is not raised and instead the OnAnyPlaybackStateChanged event is being called multiple times:
  
  If you try to reopen the closed media source, it is not detected neither.
