Universal Windows Platform

Welcome to the Windows Platform Developer (WPDev) Feedback site. This feedback forum provides the WPDev community with a channel for feedback on the following topics:

  • Windows developer platform (APIs, runtimes, and controls)
  • Dev Center (developer portal, back-end services, reporting/analytics and process)
  • Microsoft Store

Your suggestions will be reviewed by the Windows platform developer team, providing feedback to help with planning ideas and to better understand how developers are using the development platform.

What this forum is not intended to cover or capture:

  • Windows:
  • Documentation on docs.microsoft.com
    • Sign in to give documentation feedback via Github
  • Visual Studio / .NET

If you’re new to this whole UserVoice thing, we’d like to note two important things about this site: (a) List items (and item rankings) represent community interest in features, and does not represent an actual priority list for the product team; and (b) Suggestions made using this forum will be moderated if they do not actually represent a feature request.

How can we improve the Windows dev platform?

  1. mediaplayerelement seekbar hover thumbnail

    This feature is almost available in any web based video player or any Desktop based video player, the feature is simple. When a mediaplayerelement is playing or paused a video. and the user hover overs the seekbar, with mouse, or pen or any other input device for that perspective, wherver is the user mouse, show a small thumbnail of the video file at that specific position, just above the seekbar ( slider ) and as the user moves the mouse along the seekbar, the thumbnail should update accordingly.

    • Virtual MIDI ports

      I'd like to see an API to create virtual MIDI ports built into Windows. The Surface touch screen has tons of possibilities as a MIDI controller, but this currently requires installing a 3rd party driver, which is not a great end user experience. Built in RtpMIDI would be nice too, but at least this would be achievable without a kernel mode driver if we had virtual MIDI ports.

      • Make the default display setting for external screens a user setting

        Working in ABO (Activity Based Office) I use different hardware to my Surface all the time. Each time I sit down the display setting for the external screen is to clone but I want it to be extended.

        My Customer (I'm an Office 365 Consultant) are struggling with the adoption of this new way of working because of simple things like this that annoy and takes 2-10 minutes per person per working spot.

        I want the screen setting to be an option, where I can set my preferance as a default.

        • MediaStreamSample: Add way to create sample from Direct3D Surface

          It is possible for us to get a D3DDevice from MediaStreamSource, as indicated by admins here:

          https://wpdev.uservoice.com/forums/110705-universal-windows-platform/suggestions/31915711-mediastreamsource-add-way-to-use-imfgetservice-fr

          I can verify that this works. But unfortunately it is not possible to create a MediaStreamSample from D3D Surface. So while we can use D3D to do hardware accelerated video decoding, it is not possible to pass the decoded samples (in a surface) to the MF pipeline through MediaStreamSource.

          Please add an overload to create a MediaStreamSample from a D3D Surface. This will allow us to do full hardware accelerated video decoding.

          • Multimedia timer

            We need a proper multimedia timer to create a good quality midi player/editor. It needs to work as good as the one available in winmm.dll
            1 ms resolution.

            • Fix the WinRT MIDI APIs

              The new WinRT MIDI APIs are broken and have been since their introduction with no sign of plans to be fixed. In addition, the functionality they provide is still lacking compared to other platforms.

              There is information on this in the other MIDI topics on this page, and on GitHub if you do an issue search for "winrt midi" or "uwp midi". Please look into how musicians and developers use MIDI and what we would like to be able to do with devices like the Surface, and prioritize giving us the ability to innovate here.

              • Support HLS version 7 so Enterprises can move to Fragmented MP4 backed streams

                Apple announced support for Fragmented MP4 backed HLS Streams under HLS version 7: https://developer.apple.com/videos/play/wwdc2016/504/ at WWDC 2016.

                We are looking to change the way our HLS streams are generated and Windows seems to be one of the few platforms that doesn't support playing these type of streams.

                This will also impede our ability to reuse these fMP4s for MPEG DASH in the future.

                Can you please add support for this?

                • Add TimedTextStreamDescriptor to enable subtitles from MediaStreamSource

                  The MediaPlayerElement supports various subtitle formats. But when we play a video file using MediaStreamSource, it is not possible to pass through the subtitle streams, because we cannot create MediaStreamDescriptors for them. So audio and video works, but subtitles don't work.

                  Since subtitles are demuxed on-the-fly during playback, we cannot use TimedTextSource either, this would require the complete stream/file to be available during creation...

                  This would be very helpful to make the MS initiated FFmpegInterop truly unviersally useful.

                  • [UWP] Media Player playback cancellation through phone call or other media app

                    I think I found a problem in Media Player. The problem happens on phone if media player is paused from another media app. In this case will be fired only MediaPlayer.PlaybackSession.PlaybackStateChanged event and it is not possible to detect whether app was paused through user or system. But if phone calls then will be simulated SystemMediaTransportControls pause button click (MediaPlayer.SystemMediaTransportControls.ButtonPressed event) and on phone call I can correctly stop my player and change some states. Why is it so? I think in first case must be fired ButtonPressed event too like it happens on phone call. Please add that capability.

                      • Codecs for UWP Media Element

                        uwp Media Element or MediaPlayerElement are fantastic with UI.But their codecs to play different kinds of audio and video files is very limited. Please integrate ffmpeg or vlc libraries by default in these xaml elements to make it easier for developers to build apps that run all kinds of video and audio files.
                        Thankyou

                        • MediaPlayer playback with CustomAudioEffect would be influence by UI thread

                          I add a CustomAudioEffect which is EQ (I've also tried using official UWP sample's EchoEffect) to MediaPlayer.

                          Although it seems CustomAudioEffect is running on Worker thread not UI thread, it seems media playback would also be impact when UI loading a bit heavier. I could hear my music become intermittently.

                          Please fix this.

                          • Depth Textures D3D11_DSV_READ_ONLY_DEPTH API design introducing severe overhead

                            In DX11 you can't read and write to the same texture, and that's fine, I can live with that.
                            However the API was designed that it will introduce severe overhead in the following scenario.

                            Say I have 100 objects to draw.
                            These objects are semi-transparent (alpha-blending) so I need to draw them sorted by distance to camera (back to front) and not by state changes.
                            Let's assume I have 50 objects which are Soft Particles (SP)
                            And 50 objects that are triangle meshes (TM)

                            Both SP and TM use alpha blending.
                            SP don't do depth writes, but they do depth-tests…

                            • Read currently played song

                              I would like to read currently played song or content in Windows 10. Use case: As neither Groove nor Spotify have a lyrics functionality (anymore) I created a simple UWP app to manage lyrics for songs. I would like to add a function that automatically loads the lyrics to the song that is played right now.

                              To solve that, it would be enough to have read access to the System Media Transport Controls data of other apps. Following data would be great:
                              - Title
                              - Artist
                              - Album cover (optional)
                              - App name
                              - Is playing or not

                                Background audio playback working on Build 14393 does not work on Build 15063.
                                It stops on the way.
                                I hope you can fix it.

                                  Behind the portal, the user could control which microphones the Lumia would use to circumvent the bug affecting the Lumias 930 Brazilians.

                                  • Add Ogg Vorbis/Opus to AudioEncodingProperties

                                    It would be extremely helpful to be able to create MediaSourceStreams for audio streams in the Vorbis and/or Opus formats. In my case, I need this functionality for implementing Shoutcast/Icecast functionality.

                                    • MediaPlayer fails opening .MKV from URL in Creators Update

                                      We have a MediaPlayer that works with OneDrive MKV streams in previous versions but not in Creators Update.

                                      If we put the MKV in another service or server the video is reproduced but the connection with OneDrive has been lost. Player raises "SourceNotSupported" error.

                                      Please help.

                                        Hi, we can’t get this to repro.

                                        I just tried the following:
                                        1) Upload MKV to OneDrive
                                        2) One OneDrive, right-click the file, “Share” and choose to get a link
                                        3) Attempt to use the resulting URL to play the file

                                        Using MediaEngineTest and WMP, this fails on both CU and AU for me. And same result with an MP4.

                                        Please share a proper repro else as we can’t reproduce.

                                      • audio routing for media headset to speaker or vice versa (UWP)

                                        allow developers to route audio from headset to speaker even if headset is connected, or provide a sample for that

                                        • User level App-to-App media (Audio/MIDI/Video)

                                          Windows should allow users to freely redirect media (Audio, MIDI even Video someday, I guess) from/to the Hardware(audio interface, webcam, etc) and/or Applications (even considering "The Desktop" as a video+audio media generator).

                                          Any media (Audio/MIDI/Video) generator/consumer (be it an app or an hardware device) should be treated as a freely connectable node, instead of an hardwired starting/ending point, like today.

                                          This would allow the user, through the OS, to "detach" an App media output from its default interface (audio/midi card, screen/window) and "re-attach" it to another App (or device) input.

                                          An example of this "An application as a node in…
