I'm trying to find a solution to play 'HLS/TS' content from URI.
I'm coding on VS (xamarin forms/cross platform) but can't found a way or Renderer for my Tizen project.
at the moment I have this function ( But it's not compatible with updated version of xamarin.forms) and it can't play HLS/TS stream (just video content 'like mp4/mkv'):
public async Task PrepareAsync()
{
State = PlayerState.Preparing;
var display = new Multimedia.Display(Forms.Context.MainWindow);
_player.Display = display;
await _player.PrepareAsync();
State = PlayerState.Prepared;
}
Thank you
It may be possible that ExoPlayer can help you.
ExoPlayer is an open source library that exposes the lower-level Android audio APIs. ExoPlayer supports high-performance features like DASH and HLS streaming that are not available in MediaPlayer. You can customize the ExoPlayer code, making it easy to add new components. ExoPlayer can only be used with Android version 4.1 and higher.
To make use of ExoPlayer, add the following code to your MainActivity (Xamarin):
((MediaManagerImplementation)CrossMediaManager.Current).MediaSessionManager = new MediaSessionManager(Application.Context, typeof(ExoPlayerAudioService));
var exoPlayer = new ExoPlayerAudioImplementation(((MediaManagerImplementation)CrossMediaManager.Current).MediaSessionManager);
CrossMediaManager.Current.AudioPlayer = exoPlayer;

An alternative title could be: What happened to PIN_CATEGORY_STILL?
I am currently comparing images that were captured using DirectShow and PIN_CATEGORY_STILL with images that were captured using UWP MediaCapture.
On the device I am testing/playing around with DirectShow and MediaCapture, DirectShow detects a PIN_CATEGORY_STILL but I am not able to initialize an instance of MediaCapture with anything other than PhotoCaptureSource.VideoPreview.
MediaCaptureInitializationSettings settings = new()
{
VideoDeviceId = someDeviceId,
PhotoCaptureSource = PhotoCaptureSource.Photo
};
MediaCapture capture = new();
// this throws an exception
// "The capture source does not have an independent photo stream."
await capture.InitializeAsync(settings);
At this point I'm not even sure if PhotoCaptureSource.Photo is meant to be used as an equivalent to PIN_CATEGORY_STILL.
Images captured with PIN_CATEGORY_STILL are way brighter in a dark environment and have a much better quality (in file size and resolution) (which is clear to me, since I am using PhotoCaptureSource.VideoPreview for MediaCapture).
Considering this resource Win32 and COM for UWP apps, it seems like UWP MediaCapture does not use DirectShow underneath but MediaFoundation (which is meant to be a successor for DirectShow).
This article led me to this StackOverflow question Media Foundation is incorrectly marking still image capture stream descriptors as video capture, which basically states that MediaFoundation has no PIN_CATEGORY_STILL but returns 1 FPS as video capability for such devices (or profiles).
Since I am not directly using MediaFoundation nor C++, I tried testing this by querying GetAvailableMediaStreamProperties:
private void Foo()
{
var videoPreviewProperties = GetEncodingProperties(MediaStreamType.VideoRecord);
var photoProperties = GetEncodingProperties(MediaStreamType.Photo);
var videoRecordProperties = GetEncodingProperties(MediaStreamType.VideoPreview);
}
private List<VideoEncodingProperties> GetEncodingProperties(MediaStreamType streamType)
{
// MediaCapture was previously initialized with PhotoCaptureSource.VideoPreview
return MediaCapture.VideoDeviceController
.GetAvailableMediaStreamProperties(streamType)
.OfType<VideoEncodingProperties>()
.ToList();
}
None of these returns a VideoEncodingProperties with only 1 FPS.
To test MediaCapture any further I tried some of the sample applications from here UWP sample. I tried CameraAdvancedCapture, CameraOpenCV and CameraManualControls, but the results were not nearly as good as good old PIN_CATEGORY_STILL.
What happened to PIN_CATEGORY_STILL?
Is there any way to capture images without DirectShow/PIN_CATEGORY_STILL and still keeping this level of quality?
Any enlightenment is much appricated.
I have an Ionic / Cordova application hosted in the Windows UWP application, and which I am looking into swapping to host within a WPF application (latest .net, eg 6.0), and using WebView2.
Note, the Ionic/Cordova part is not really relevant to this question, this is purely related to WPF.
When running on a Tablet (eg Microsoft surface), I need to resize the app when the soft keyboard is shown, and hidden.
When in UWP, I could hook into the following events in my TypeScript file...
let w = <any>window;
const inputPane = w.Windows.UI.ViewManagement.InputPane.getForCurrentView();
if (!inputPane) {
this.logger.error('WindowsKeyboardService.hookupKeyboardHandlers: could not get inputPane');
return;
}
inputPane.addEventListener('showing', _ => this.onWindowsKeyboardUp);
inputPane.addEventListener('hiding', _ => this.onWindowsKeyboardClose);
So I won't have the WinJS any longer in the WPF, so I will do all the native in the WPF and then call into the JS myself using the appropriate API on the webview.
If I was in UWP, I could do something like the following:
System.Windows.UI.ViewManagement.InputPane.GetForCurrentView().Showing += (s, args) =>
{
GeneralTransform gt = loginButton.TransformToVisual(this);
Point buttonPoint = gt.TransformPoint(new Point(0, loginButton.RenderSize.Height - 1));
var trans = new TranslateTransform { Y = -(buttonPoint.Y - args.OccludedRect.Top) };
loginButton.RenderTransform = trans;
args.EnsuredFocusedElementInView = true;
};
But in WPF, I do not seem to have the `System.Windows.UI namespace:
Is there an equivalent way of doing this within a WPF application?
Update 1
I found this sample code
The whole solution will build in .net framework (4.7), but not in .net 6, as still missing the namespace Windows.UI. Perhaps this is renamed to something?
Update 2
I create a new WinUI project. Calling
var pane = Windows.UI.ViewManagement.InputPane.GetForCurrentView();
gives the same Element Not found error. I call this in a button click event, to give the main app/Window plenty of time to be fully initialized.
Note I am trying this out running from Visual Studio (i.e. Desktop Windows 10), and not on an actual tablet at this stage.
I this similar post where there is a comment
#LeftTwixWand ApplicationView.GetForCurrentView and CoreApplication.GetCurrentView() are only for UWP apps. For WinUI 3 desktop apps, use the Window class for some of the functionality. I'm not completely sure but some of them also now a GetForWindowId method.
It mentions using the Window class, but there is nothing on how to do what I am after here (monitoring the soft keyboard show/hide events).
Update 3
Following #Victor below, I added the code and it asks me to install
#Victor is this correct?
For WPF you just need to use net6.0-windows10.0.17763.0 target framework or newer. APIs will be available for you via existing Interop classes. Do not use System.Runtime.InteropServices.WindowsRuntime, it is .net framework approach.
IntPtr handle = new WindowInteropHelper(window).Handle;
InputPane inputPane = InputPaneInterop.GetForWindow(handle);
I'm trying to play a HDHomeRun Connect Video source from a url in the following format: http://x.x.x.x:xxxx/auto/v4.1. This video source is an MPEG2 video encoding and AC3 audio encoding.
I've tried using the Samsung Tizen.TV .NET sample with the following source but the video never plays.
_player = new Tizen.Multimedia.Player();
var mediaSource = new Multimedia.MediaUriSource(uri);
_player.SetSource(mediaSource);
var display = new Multimedia.Display(Window.Instance);
_player.Display = display;
await _player.PrepareAsync();
The player state gets stuck in preparing, and the await _player.PrepareAsync() call never finishes. It is worth noting that I'm using the Tizen Samsung TV Emulator. Do I need to transcode the stream from the HDHomeRun to be playable? Are there any other measures I might be missing for the Video to play?
Ultimately, the Display property of the player wasn't being set correctly. The property that worked for me (found from investigating the JuvoPlayer code was this:
var display = new Multimedia.Display(((FormsApplication)Forms.Context).MainWindow);
_player.Display = display;
When you are to develop a Tizen .NET application, please be aware of which UI framework your project is targetted for among 3 different types: Xamarin.Forms, (pure) ElmSharp, and Tizen.NUI.
Unless your project is based on the Tizen.NUI framework, you shouldn't use Tizen.NUI.Window.Instance and types in Tizen.NUI namespace in any case. Instead, you will have to use types of ElmSharp or Xamarin.Forms.Platform.Tizen namespace for platform-specific code in your application.
Since the internal implementation of Xamarin.Forms for Tizen is based on ElmSharp, FormsApplication.MainWindow will return a ElmSharp.Window instance which can be used to instantiate a Tizen.Multimedia.Display object. That's why the code in your answer worked.
I have Lumia 830 and i've tried to create flashlight app in UWP C#. my device Flashlight works great but i don't know why i can't create my own app turn on / off Torch of my phone.
I use Lamp class :
var lamp = await Lamp.GetDefaultAsync();
if (lamp == null)
{
ShowErrorMessage("No Lamp device found");
return;
}
lamp.IsEnabled = true;
when run this code on my phone "lamp" is null and it couldn't find my FlashLED. I've got this code from MSDN.Microsoft.com and thay said
If the returned object is null, the Lamp API is unsupported on the
device. Some devices may not support the Lamp API even if there is a
lamp physically present on the device.
This class doesn't work on my Lumia 830 i don't kno why? :(
also i use this code :
var mediaDev = new MediaCapture();
await mediaDev.InitializeAsync();
var videoDev = mediaDev.VideoDeviceController;
var tc = videoDev.TorchControl;
if (tc.Supported)
{
// But wait, for this to work with Blue camera drivers, we have to Start a recording session
// Create video encoding profile as MP4
var videoEncodingProperties = MediaEncodingProfile.CreateMp4(VideoEncodingQuality.Vga);
// Start Video Recording
var videoStorageFile = await KnownFolders.VideosLibrary.CreateFileAsync("tempVideo.mp4", CreationCollisionOption.GenerateUniqueName);
await mediaDev.StartRecordToStorageFileAsync(videoEncodingProperties, videoStorageFile);
// Turn on Torch
mediaDev.VideoDeviceController.TorchControl.Enabled = true;
}
this code works and my FlashLED turn on but it record video and it take's user SD Card memory.
please help me if you know there is best way to turn on/off Torch or FlashLED.
thanks in advance

The Lamp API is designed for Windows 10 devices only and you can only use it on devices which support the API. Currently supported devices are 950/950XL, 650, and 550. Older devices will not be updated to support this API. You should fall back to the Windows 8.1 method of turning on flash when you detect that the lamp device is not available on older devices.

Please test default sample named LampDevice (cf. https://github.com/Microsoft/Windows-universal-samples/tree/master/Samples/LampDevice). Do you have the same behavior ? I just tested on Lumia 930 it works fine. No Lumia 830 to test it.
I have C# App using the Mono Framework and GTK UI running on Mac.I have problems regarding the look and feel of the Filechooser dialog.As per gtk https://developer.gnome.org/gtk3/stable/GtkFileChooserDialog.html I should get these icons
But what i get is this one without proper icons in the left hand panel or icons of the drives.For drives there a folder named Volumes and the user needs to open it manually.I think that is not a native Mac user expects.I have posted 2 screenshots obtained from the web.
I have this GTK Version(2.2) Bundled with Mono for Mac.What should i do to get a more native look and feel? Please advice
You can use either the older open-source MonoMac or the newer Xamarin.Mac to open a NSOpenPanel and use the native OS-X file selector instead of the xplat based GTK 2 version.
Mixing MonoMac dialogs on top of GTK# is possible as long as you remember to initialize the application via the MonoMac static method NSApplication.Init(). Do this earlier in the application startup, but after GTK# initializes.
As for opening the native NSOpenPanel, here is an example used within a GTK# Button click handler:
button.Clicked += (object sender, EventArgs e) => {
Application.Invoke (delegate {
var nsOpenPanel = new NSOpenPanel ();
nsOpenPanel.ReleasedWhenClosed = true;
nsOpenPanel.Prompt = "Select file";
var result = nsOpenPanel.RunModal ();
if (result == 1) {
button.Label = nsOpenPanel.Url.ToString ();
}
});
};
Note: It is always wise to wrap the calls within an Application.Invokedelegate so everything is executed on the main GTK UI thread.
