Trying to make some mediaplayer app. I put the mediaelement on wpf, wrote code to open media. But when i try to play it nothing is happening...
public void ContinueFileOpenPicker(FileOpenPickerContinuationEventArgs args)
{
if (args.Files.Count > 0)
{
foreach (StorageFile file in args.Files)
{
if (playlist.Contains(file.Path)) return;
playlist.Add(file.Path);
}
}
}
private void PlayButton_OnClick(object sender, RoutedEventArgs e)
{
MyMedia.Source = new Uri(playlist[0], UriKind.RelativeOrAbsolute);
MyMedia.Play();
}
Checked that mediaelement source isn't empty, it has a right value of path.
Try to rebuild like that, still doesnt work
private async void PlayButton_OnClick(object sender, RoutedEventArgs e)
{
var stream = await Playlist[0].OpenAsync(FileAccessMode.Read);
MyMedia.SetSource(stream, Playlist[0].ContentType);
MyMedia.Play();
}
Sorry it was my mistake.
Into my XAML, I forgot that the AutoPlay property of the MediaElement control was set to false.
This solve my problem.
Couple of things you need to watch out.
foreach (StorageFile file in args.Files)
{
if(playlist.Contains(file.Path))
{
return;// Dont return use continue. You will probably skip rest of the files.
}
playlist.Add(file.Path);
}
Add a Watch/Quickwatch to see if the new Uri(playlist[0], UriKind.RelativeOrAbsolute) points to a right location.
Setup source from storage file:
var storageFile = await KnownFolders.MusicLibrary.GetFileAsync("line.mp3");
var stream = await storageFile.OpenAsync(FileAccessMode.Read);
mediaElement.SetSource(stream, storageFile.ContentType);
mediaElement.Play();
I got it from this answer: How to play file from Library by MediaElement?

I'm trying to Get a Auto Next method i've tried using a Index Counter but I think I misunderstand how to properly set a list using the FilePicker
The code for the FilePicker is following :
public async void pick_Click_1(object sender, RoutedEventArgs e)
{
List<StorageFile> fileList = new List<StorageFile>();
var fop = new FileOpenPicker();
fop.FileTypeFilter.Add(".mp3");
fop.FileTypeFilter.Add(".mp4");
fop.FileTypeFilter.Add(".avi");
fop.FileTypeFilter.Add(".wmv");
fop.ViewMode = PickerViewMode.List;
pickedFileList = await fop.PickMultipleFilesAsync();
// add the picked files to our existing list
fileList.AddRange(pickedFileList);
foreach (StorageFile file in pickedFileList)
{
Playlist.Items.Add(file);
var stream = await file.OpenAsync(Windows.Storage.FileAccessMode.Read);
videoMediaElement.SetSource(stream, file.ContentType);
}
videoMediaElement.Play();
The Current method i have for switching tracks|Videos
private async void itemclicked(object sender, ItemClickEventArgs e)
{
var file = e.ClickedItem as StorageFile;
if (file != null)
{
var stream = await file.OpenReadAsync();
videoMediaElement.SetSource(stream, file.ContentType);
}
}
Empty Event im trying to use to do this.
private void Element_MediaEnded(object sender, RoutedEventArgs e)
{
}
I've looked threw all the Microsoft Sample's. Issue Being They use the Mediaplayerelement += Mediaplayer And im using the MediaElement
The Answers Im looking for Can be A Resolution to my problem or assisting me in better understanding how to globally set the source of the mediaplayer using the Current or new list from the picker, Im new to all this and trying to grasp everything better Thank you!
I ended up taking Tousee's advice to seem's he's my mentor at this stage, I used the MediaplayerElement and mediaPLaybacklist's which made life Easier. And almost instantly fixed my problem.
So I was trying to loop Background music in my UWP App, I have a class called soundControl that handles music and sounds like this:
public class soundControl
{
private static MediaElement loop = new MediaElement();
public static async void stopLoop()
{
loop.Stop();
}
public static async void loadLoopTimeBG()
{
Windows.Storage.StorageFolder folder = await Windows.ApplicationModel.Package.Current.InstalledLocation.GetFolderAsync(#"Assets\Sounds");
Windows.Storage.StorageFile file = await folder.GetFileAsync("battle.wav");
var stream = await file.OpenAsync(Windows.Storage.FileAccessMode.Read);
loop.AutoPlay = false;
loop.SetSource(stream, file.ContentType);
loop.IsLooping = true;
}
public static void loopTimeBG()
{
loop.Play();
}
And whenever I want to play this music I call :
soundControl.loadLoopTimeBG();
soundControl.loopTimeBG();
the problem is the it plays just one time and stops and I have no Idea why
I tried another approach like:
loop.MediaEnded += mediaEnded;
and the event handler like this:
private static void mediaEnded(object sender, RoutedEventArgs e)
{
loop.Position = TimeSpan.Zero;
loop.Play();
}
it also didn't work and when debugging it doesn't even triger the mediaEnded event when music is complete.
Any help here would be most appreciated.
Thanks
MediaPlayer
Windows.Media.Playback.MediaPlayer is the recommended player for UWP that does not require to be in the XAML visual tree.
Its API is very similar to MediaElement:
private static MediaPlayer _mediaPlayer = new MediaPlayer();
public static async Task PlayUsingMediaPlayerAsync()
{
Windows.Storage.StorageFolder folder = await Windows.ApplicationModel.Package.Current.InstalledLocation.GetFolderAsync(#"Assets");
Windows.Storage.StorageFile file = await folder.GetFileAsync("Click.wav");
_mediaPlayer.AutoPlay = false;
_mediaPlayer.Source = MediaSource.CreateFromStorageFile(file);
_mediaPlayer.MediaOpened += _mediaPlayer_MediaOpened;
_mediaPlayer.IsLoopingEnabled = true;
}
private static void _mediaPlayer_MediaOpened(MediaPlayer sender, object args)
{
sender.Play();
}
You can even display the visuals of a MediaPlayer in XAML using MediaPlayerElement.
MediaPlayer allows for even more advanced playback scenarios using the MediaPlaybackList with support for looping, shuffle and gapless playback.
mediaElement.SetPlaybackSource(mediaPlaybackList);
MediaElement
After some digging around it seems that there are two issues.
MediaElement is XAML based control (in the Windows.UI.Xaml.Controls namespace), and it seems that it does not work properly until it is actually attached to a visual tree. Once you put the MediaElement on the page, it works as expected.
Secondly, loading source media does not happen immediately. Once you set the source, the control needs some time to actually load the media. For this purpose, you can use the MediaOpened event, that will notify you once it is really loaded.
So the code could look somewhat like this:
public static async Task LoadAndPlayAsync()
{
Windows.Storage.StorageFolder folder = await Windows.ApplicationModel.Package.Current.InstalledLocation.GetFolderAsync(#"Assets");
Windows.Storage.StorageFile file = await folder.GetFileAsync("Click.wav");
var stream = await file.OpenAsync(Windows.Storage.FileAccessMode.Read);
loop.AutoPlay = false;
loop.SetSource(stream, file.ContentType);
//or simpler -
//loop.Source = new Uri("ms-appx:///Assets/Click.wav", UriKind.Absolute);
loop.MediaOpened += Loop_MediaOpened;
loop.IsLooping = true;
}
private static void Loop_MediaOpened(object sender, Windows.UI.Xaml.RoutedEventArgs e)
{
//play once the media is actually ready
loop.Play();
}
And before you call the LoadAndPlayAsync method, you have to attach the control somewhere (for example in a Grid):
GridContainer.Children.Add(SoundController.loop);
await SoundController.LoadAndPlayAsync();
I have created a sample project for my tests on my GitHub, you can check it out to see how I implemented it. The first button in the app attaches the control and the second loads and plays the sound. You can see that if you click only the second one, the sound does not play.
I'm new in C# programming, I created a combobox with items and I want that items to play sound when i chose one, like this,
or that.
I'm using Visual Studio 2015.
Could would be in methods play1 and play2
private void AudioComboBox_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
if (AudioComboBox.SelectedIndex == AudioComboBox.Items.IndexOf("Sali 3la Mohammed 1"))
{
play1();
}
else if (AudioComboBox.SelectedIndex == AudioComboBox.Items.IndexOf("Sali 3la Mohammed 2"))
{
play2();
}
}
private void play1()
{
}
private void play2()
{
}
You can use MediaElement or the new AudioGraph to play sounds in UWP.
MediaElement is the simpler approach, which has the disadvantage of causing the music stop on Mobile devices, so it is really not too appropriate your purpose.
MediaElement player = new MediaElement();
var stream = await yourSoundFile.OpenAsync(Windows.Storage.FileAccessMode.Read);
player.SetSource(stream, file.ContentType);
player.Play();
AudioGraph is specifically created for sound effects in UWP apps and is the best choice for you. There is a quick and simple tutorial on Loek van den Ouweland's blog, so I definitely recommend you to check it out. Basically you need to create an AudioGraph instance and with it AudioFileInputNodes for each of the sounds you need.
This should work
private void AudioComboBox_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
if (AudioComboBox.SelectedIndex == AudioComboBox.Items.IndexOf("Sali 3la Mohammed 1"))
{
play1();
}
else if (AudioComboBox.SelectedIndex == AudioComboBox.Items.IndexOf("Sali 3la Mohammed 2"))
{
play2();
}
}
private void play1()
{
SoundPlayer simpleSound = new SoundPlayer("sound1.wav");
simpleSound.Play();
}
private void play2()
{
SoundPlayer simpleSound = new SoundPlayer("sound2.wav");
simpleSound.Play();
}
I have several .wav and .mp3 files in my app under Assets/Audio, and I'm trying to play them when something is tapped in the UI. I've written the following code (with the file name hardcoded for testing purposes), but when the function is triggered, no sound plays. If I replace attempting to play from a file to playing an audio stream created by Windows.Media.SpeechSynthesis.SpeechSynthesizer, everything works fine.
private async void SoundItem_Tapped(object sender, TappedRoutedEventArgs e)
{
ListViewItem soundItem = sender as ListViewItem;
if (soundItem.IsSelected)
{
Uri sourceUri = new Uri(String.Format("ms-appx:///Assets/Audio/151Cry.wav", UriKind.Absolute));
await PlayAudio(sourceUri, soundItem);
}
else if (inUsePlayers.ContainsKey(soundItem))
{
MediaElement player = inUsePlayers[soundItem];
player.Stop();
inUsePlayers.Remove(soundItem);
players.Enqueue(player);
}
else
{
}
}
private async Task PlayAudio(Uri sourceUri, ListViewItem soundItem)
{
MediaElement player = RequestPlayer(soundItem);
player.Source = sourceUri;
player.IsLooping = true;
await player.Dispatcher.RunAsync(CoreDispatcherPriority.Normal, () =>
{
player.Stop();
player.Play();
});
}
Here's the location of the file within the tree:
Aside from dragging the sound files into the project, I've haven't done anything. Maybe they need to be added to a resource file or copied to the output folder as well? I expected that something would throw an exception if the item pointed to by the URI didn't exist, but nothing's being thrown, even when I give it a bogus filename.
You need to do following things to play you media element.
Your resource files should be set to "Copy to Output directory"
value to "Copy if newer" or "Copy always". to do this right
click your resource file go to Properties and set Copy to Output directory value to Copy always and Build action to
content
Your player(MediaElement) should be added somewhere to View xaml
tree. I do not know your RequestPlayer method is adding
mediaEelement to view xaml or not. e.g
layoutRoot.Children.Add(player)
You need to register Player_MediaOpened event to play your
audio file. If you call 'play' before player is opened media will
not play the sound... and if you want that if any thing is happend
to your player not playing than register Player_MediaFailed it
will give you the reason why it is filed to play.
here is the code.
private async Task PlayAudio(Uri sourceUri, ListViewItem soundItem)
{
MediaElement player = RequestPlayer(soundItem);
player.IsLooping = true;
player.AutoPlay = false;
player.MediaOpened += Player_MediaOpened;
player.MediaFailed += Player_MediaFailed;
player.Source = sourceUri;
player.IsLooping = true;
//Add media element to xaml tree if not added by your RequestPlayer Method..
this.LayoutRoot.Children.Add(player);
}
private void Player_MediaFailed(object sender, ExceptionRoutedEventArgs e)
{
}
private async void Player_MediaOpened(object sender, RoutedEventArgs e)
{
await player.Dispatcher.RunAsync(CoreDispatcherPriority.Normal, () =>
{
player.Play();
});
}
Hope this helps...
This seems like a serious bug :
private void LayoutRoot_Drop(object sender, DragEventArgs e)
{
if ((e.Data != null) && (e.Data.GetDataPresent(DataFormats.FileDrop)))
{
FileInfo[] files = (FileInfo[])e.Data.GetData(DataFormats.FileDrop);
using (FileStream fileStream = files[0].OpenRead())
{
//Code reaching this point.
BitmapImage bmpImg = new BitmapImage();
bmpImg.ImageOpened += new EventHandler<RoutedEventArgs>(bmpImg_ImageOpened);
bmpImg.ImageFailed += new EventHandler<ExceptionRoutedEventArgs>(bmpImg_ImageFailed);
try
{
bmpImg.SetSource(fileStream);
}
catch
{
//Code dosen't reach here.
}
}
}
}
void bmpImg_ImageFailed(object sender, ExceptionRoutedEventArgs e)
{
//Code dosen't reach here.
}
void bmpImg_ImageOpened(object sender, RoutedEventArgs e)
{
//Code dosen't reach here.
}
I am experiencing a very strange behivour. Running this code on my computer, it works - when you drag a JPG on the LayoutRoot I can break inside bmpImg_ImageOpened().
But on a different machine it won't work - when dragging a JPG, I can break in the drop event but after SetSource() nothing happens : no exceptions are thrown, and non of the callbacks are invoked.
I tried it on another machine and it also didn't work.
edit:
On all of the machines, when adding an Image class and setting it's Source property to the bitmapImage, the image is shown fine. so I guess it's an issue with the callbacks. This is not enough because I still need those events.
I am banging my head here, what could it be ?
This is simply how Silverlight has always behaved. ImageOpened only fires if the image is downloaded and decoded (i.e. using Source). It does not fire when using SetSource. If you need access to the dimensions after loading your image either use WriteableBitmap for the PixelWidth and PixelHeight properties (instead of BitmapImage) or do something like:
img.Source = bmpImg;
Dispatcher.BeginInvoke(() =>
{
FakeImageOpened(); // Do logic in here
});
You have to set
bitmapImage.CreateOptions = BitmapCreateOptions.None;
Then the ImageOpened event is fired. This is because the default Options are CreateDelayed
