Overview

The basic syntax is to create a MediaPlayer with an implementation deriving from PlayerHostBase inside.

<media:MediaPlayer x:Name="Player">
    <media:NAudioPlayerHost Source="MyAudio.mp3" />
</media:MediaPlayer>

AutoPlay

Gets or sets whether to auto-play the file when setting the source.

IsPlaying

Gets or sets whether the media file is playing or paused.

IsVideoVisible

Gets or sets whether to show the video.

Loop

Gets or sets whether to loop.

Position

Source

Gets or sets the path to the media file to play. If resetting the same file path, you may need to first set an empty string before resetting the value to ensure it detects the value change.

SpeedFloat

Gets or sets the speed multiplier.

SpeedInt

Gets or sets the speed as an integer, where normal playback is 0. Useful for binding to a slider.

Title

Gets or sets the display title of the media file. A title is set by default and you can override it using this property.

Using MPV Player in WPF

Add MediaPlayer.Wpf.Mpv to your project.
Drop this code into your page.

xmlns:media="https://github.com/mysteryx93/MediaPlayerUI.NET"
...
<media:MediaPlayer x:Name="Player">
    <media:MpvPlayerHost Source="MyVideo.mp4" />
</media:MediaPlayer>

Download the latest version of libmpv from here. MPV will require a different DLL for x64 and x86.

Copy the DLL into the project folder and add this to your project file

<ItemGroup>
    <None Update="mpv-1.dll">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
    </None>
</ItemGroup>

Optionally, set DllPath on MpvPlayerHost to help find the DLL.

To add keyboard shortcuts, add this code to your window

<Window.InputBindings>
    <KeyBinding Key="Space" Command="{Binding PlayPauseCommand, ElementName=Player}" />
    <KeyBinding Key="Right" Command="{Binding SeekCommand, ElementName=Player}" CommandParameter="{media:Int32 1}" />
    <KeyBinding Key="Right" Modifiers="Ctrl" Command="{Binding SeekCommand, ElementName=Player}" CommandParameter="{media:Int32 10}" />
    <KeyBinding Key="Left" Command="{Binding SeekCommand, ElementName=Player}" CommandParameter="{media:Int32 -1}" />
    <KeyBinding Key="Left" Modifiers="Ctrl" Command="{Binding SeekCommand, ElementName=Player}" CommandParameter="{media:Int32 -10}" />
    <KeyBinding Key="Up" Command="{Binding ChangeVolumeCommand, ElementName=Player}" CommandParameter="{media:Int32 5}" />
    <KeyBinding Key="Down" Command="{Binding ChangeVolumeCommand, ElementName=Player}" CommandParameter="{media:Int32 -5}" />
    <KeyBinding Key="Enter" Modifiers="Alt" Command="{Binding ToggleFullScreenCommand, ElementName=Player}" />
</Window.InputBindings>

Using NAudio Player in WPF

Audio-only.

Add MediaPlayer.Wpf.NAudio to your project.
Drop this code into your page.

xmlns:media="https://github.com/mysteryx93/MediaPlayerUI.NET"
...
<media:MediaPlayer x:Name="Player">
    <media:NAudioPlayerHost Source="MyAudio.mp3" />
</media:MediaPlayer>

NAudioPlayerHost Properties

Standard PlayerHostBase properties

Rate

Gets or sets the playback rate as a double, where 1.0 is normal speed, 0.5 is half-speed, and 2 is double-speed. Default = 1.

Pitch

Gets or sets the playback pitch as a double, rising or lowering the pitch by given factor without altering speed. Default = 1.

PositionRefreshMilliseconds

Gets or sets the interval in milliseconds at which the position bar is updated.

UseEffects

Gets or sets whether to enable pitch-shifting effects. By default, effects are enabled if Rate, Pitch or Speed are set before loading a media file. If file is loaded at normal speed and you want to allow changing it later, this property forces initializing the effects module. This property must be set before playback. Default = False.

VolumeBoost

Gets or sets a value that will be multiplied to the volume. Default = 1.

Event: MediaError

Occurs when the player throws an error.

Event: MediaFinished

Occurs when media playback is finished.

Using BASS Player in Avalonia

Audio-only. Supports altering Pitch, Rate and Speed. Set UseEffects="True" or set Pitch/Rate/Speed at design-time.

BASS is free for non-commercial use. If you are a non-commercial entity (eg. an individual) and you are not making any money from your product (through sales, advertising, etc) then you can use BASS in it for free. Otherwise, a license will be required.

Pitch-shifting audio quality is better with BASS than with NAudio/SpeedTouch.

Add MediaPlayer.Avalonia.Bass to your project.
Add styles to App.axaml

<Application.Styles>
    <FluentTheme Mode="Light"/>
    <StyleInclude Source="avares://MediaPlayer.Avalonia/Styles/Default/Theme.axaml" />
    <StyleInclude Source="avares://MediaPlayer.Avalonia/Styles/Colors/Gray.axaml" />
</Application.Styles>

Drop this code into your page.

xmlns:media="https://github.com/mysteryx93/MediaPlayerUI.NET"
...
<media:MediaPlayer x:Name="Player">
    <media:BassPlayerHost Source="MyAudio.mp3" />
</media:MediaPlayer>

Download the latest version of BASS and BASS FX from here.

bass.dll and bass_fx.dll will be required, and you can add other plugins to support more input formats. This library will auto-load all plugins in the folder.

Create a BassDlls project like this

Simply reference that project and you'll get all the DLLs for each platform.

BassPlayerHost Properties

EffectsQuick

Gets or sets whether to use the quick mode that substantially speeds up the algorithm but may degrade the sound quality by a small amount. Default = False.

EffectsAntiAlias

Gets or sets whether to enable the Anti-Alias filter. Default = False.

EffectsAntiAliasLength

Gets or sets the Anti-Alias filter length. Default = 32.

EffectsSampleRateConversion

Gets or sets the sample rate conversion quality... 0 = linear interpolation, 1 = 8 point sinc interpolation, 2 = 16 point sinc interpolation, 3 = 32 point sinc interpolation, 4 = 64 point sinc interpolation. Default = 4, set lower for better performance.

EffectsFloat

Gets or sets whether to process effects in 32-bit. True for 32-bit, False for 16-bit. Default = False, set to True for best quality.

EffectsRoundPitch

Gets or sets whether to round the pitch to the nearest fraction when pitch-shifting for improved quality.

PitchError (read-only)

Gets the pitch rounding error when EffectsRoundPitch is true.

EffectsSkipTempo

Gets or sets whether to skip tempo adjustment for maximum audio quality.

Pitch

Gets or sets the playback pitch as a double, rising or lowering the pitch by given factor without altering speed. Default = 1.

PositionRefreshMilliseconds

Gets or sets the interval in milliseconds at which the position bar is updated.

Rate

Gets or sets the playback rate as a double, where 1.0 is normal speed, 0.5 is half-speed, and 2 is double-speed. Default = 1.

UseEffects

VolumeBoost

Gets or sets a value that will be multiplied to the volume. Default = 1.

OutputSampleRate

Gets or sets the device output sample rate. 0 = auto-detected. On Linux, it cannot be auto-detected and must be set manually if different than 48000.

Event: MediaError

Occurs when the player throws an error.

Event: MediaFinished

Occurs when media playback is finished.

BassDevice class

You can get information about auto-loaded BASS plugins and supported formats using the BassDevice class.

Using Custom Players

Look at MediaPlayer.Wpf.Mpv or MediaPlayer.Avalonia.Bass. Integrating a new player is quite straightforward.

VapourSynthViewer.NET is an example of using the UI for previewing Vapoursynth video scripts.
