如何使用WPF用户界面框架编译EasyPlayPro-Win版本网页无插件视频播放器？
WPF提供了统一的编程模型、语言和框架，同时也提供了全新的多媒体交互用户图形界面，对研发人员来说，它最终将减少提供最佳用户体验和通信逻辑所需的代码行数。
目前TSINGSEE青犀视频开发的网页视频播放器EasyPlayPro-win播放器有MFC和winform版本，基于优化的考虑，我们研发了使用WPF框架编译EasyPlayPro-win播放器库。
1、先大致制作一个简单的界面，界面大致如下
xmal代码如下，里面包含各种事件，来处理逻辑程序：
<Window x:Class="EasyPlayerPro.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Title="EasyPlayerPro" Height="563" Width="785" Loaded="Onload" Closing="Window_Closing">
<Grid HorizontalAlignment="Center">
<StackPanel Height="395" HorizontalAlignment="Stretch" Name="stackPanel1" VerticalAlignment="Top" Width="751" Orientation="Horizontal">
<Image Height="228" Name="image1" Stretch="Fill" Width="631" />
</StackPanel>
<Slider Height="23" HorizontalAlignment="Center" Margin="12,417,0,0" Name="slider1" VerticalAlignment="Top" Width="739" GotMouseCapture="slider1_GotMouseCapture" Thumb.DragCompleted="slider1_DragCompleted" IsSnapToTickEnabled="True" />
<TextBox Height="23" HorizontalAlignment="Center" Margin="12,446,0,0" Name="textBox1" VerticalAlignment="Top" Width="739" TextAlignment="Left" VerticalContentAlignment="Center" Text="http://demo.easydss.com:10080/fvod/ULJyMRhZR/video.m3u8" />
<StackPanel Height="49" HorizontalAlignment="Stretch" Margin="12,475,0,0" Name="stackPanel2" VerticalAlignment="Top" Width="739" Orientation="Horizontal">
<Button Content="开始" Height="23" Name="StartBtn" Width="40" Click="StartBtn_Click" />
<Button Content="停止" Height="23" Name="StopBtn" Width="40" Click="StopBtn_Click" />
<Button Content="暂停" Height="23" Name="PauseBtn" Width="40" Click="PauseBtn_Click" />
<Button Content="单帧" Height="23" Name="SingleFrameBtn" Width="40" Click="SingleFrameBtn_Click" />
<Button Content="播放" Height="23" Name="PlayBtn" Width="40" Click="PlayBtn_Click" />
<Button Content="速度" Height="23" Name="SpeedBtn" Width="40" Click="SpeedBtn_Click" />
<ComboBox Height="23" Name="comboBox1" Width="65" SelectedIndex="9">
<ComboBoxItem Content="10" />
<ComboBoxItem Content="20" />
<ComboBoxItem Content="30" />
<ComboBoxItem Content="40" />
<ComboBoxItem Content="50" />
<ComboBoxItem Content="60" />
<ComboBoxItem Content="70" />
<ComboBoxItem Content="80" />
<ComboBoxItem Content="90" />
<ComboBoxItem Content="100" Visibility="Collapsed" />
<ComboBoxItem Content="200" />
<ComboBoxItem Content="300" />
<ComboBoxItem Content="400" />
<ComboBoxItem Content="500" />
<ComboBoxItem Content="600" />
</ComboBox>
<Button Content="全屏" Height="23" Name="FullScreenBtn" Width="40" Click="FullScreenBtn_Click" />
<Button Content="退出" Height="23" Name="CloseBtn" Width="40" Click="CloseBtn_Click" />
<Label Content="时长：00分:00秒/00分:00秒" Height="28" Name="label1" Width="353" HorizontalAlignment="Right" IsEnabled="True" HorizontalContentAlignment="Right" />
</StackPanel>
</Grid>
</Window>
2、引用libEasyplayerpro.dll动态库，把需要授权、播放、暂停等所需要的功能引用上。
[DllImport("libEasyplayerpro.dll", EntryPoint = "EasyPlayerPro_Authorize", CallingConvention = CallingConvention.Cdecl)]
static extern int EasyPlayerPro_Authorize(string license);
[DllImport("libEasyplayerpro.dll", EntryPoint = "EasyPlayerPro_Create", CallingConvention = CallingConvention.Cdecl)]
static extern IntPtr EasyPlayerPro_Create();
[DllImport("libEasyplayerpro.dll", EntryPoint = "EasyPlayerPro_Release", CallingConvention = CallingConvention.Cdecl)]
static extern void EasyPlayerPro_Release(IntPtr player);
[DllImport("libEasyplayerpro.dll", EntryPoint = "EasyPlayerPro_Open", CallingConvention = CallingConvention.Cdecl)]
static extern IntPtr EasyPlayerPro_Open(IntPtr player, string file, IntPtr hwnd, EASY_VIDEO_RENDER_TYPE render_type, EASY_VIDEO_SCALE_MODE video_mode, EASY_STREAM_LINK_MODE link_mode, int speed, int valume, int probesize, int max_analyze_duration);
[DllImport("libEasyplayerpro.dll", EntryPoint = "EasyPlayerPro_Close", CallingConvention = CallingConvention.Cdecl)]
static extern void EasyPlayerPro_Close(IntPtr player);
[DllImport("libEasyplayerpro.dll", EntryPoint = "EasyPlayerPro_Play", CallingConvention = CallingConvention.Cdecl)]
static extern void EasyPlayerPro_Play(IntPtr player);
[DllImport("libEasyplayerpro.dll", EntryPoint = "EasyPlayerPro_StepPlay", CallingConvention = CallingConvention.Cdecl)]
static extern void EasyPlayerPro_StepPlay(IntPtr player, int type);
[DllImport("libEasyplayerpro.dll", EntryPoint = "EasyPlayerPro_Pause", CallingConvention = CallingConvention.Cdecl)]
static extern void EasyPlayerPro_Pause(IntPtr player);
[DllImport("libEasyplayerpro.dll", EntryPoint = "EasyPlayerPro_Seek", CallingConvention = CallingConvention.Cdecl)]
static extern void EasyPlayerPro_Seek(IntPtr player, System.Int64 ms);
[DllImport("libEasyplayerpro.dll", EntryPoint = "EasyPlayerPro_Resize", CallingConvention = CallingConvention.Cdecl)]
static extern void EasyPlayerPro_Resize(IntPtr player, int type, int x, int y, int w, int h);
[DllImport("libEasyplayerpro.dll", EntryPoint = "EasyPlayerPro_Snapshot", CallingConvention = CallingConvention.Cdecl)]
static extern int EasyPlayerPro_Snapshot(IntPtr player, string file, int w, int h, int wait);
[DllImport("libEasyplayerpro.dll", EntryPoint = "EasyPlayerPro_Record", CallingConvention = CallingConvention.Cdecl)]
static extern int EasyPlayerPro_Record(IntPtr player, string filePath, int duration);
[DllImport("libEasyplayerpro.dll", EntryPoint = "EasyPlayerPro_Stoprecord", CallingConvention = CallingConvention.Cdecl)]
static extern int EasyPlayerPro_Stoprecord(IntPtr player);
[DllImport("libEasyplayerpro.dll", EntryPoint = "EasyPlayerPro_Setparam", CallingConvention = CallingConvention.Cdecl)]
static extern void EasyPlayerPro_Setparam(IntPtr player, EASY_PARAM_ID id, ref IntPtr param);
[DllImport("libEasyplayerpro.dll", EntryPoint = "EasyPlayerPro_Getparam", CallingConvention = CallingConvention.Cdecl)]
static extern void EasyPlayerPro_Getparam(IntPtr player, EASY_PARAM_ID id, ref Int64 param);
3、实现功能逻辑，并播放视频在界面上，输入可用url，点击播放，可出现画面。
有一点需要注意：Image这个标签需转为Handle，再把Handle传入EasyPlayerPro_Open的第三个参数上。具体的如下：
IntPtr hwnd = ((HwndSource)PresentationSource.FromVisual(image1)).Handle;
mPlayer = EasyPlayerPro_Open(mPlayer, this.textBox1.Text, hwnd, EASY_VIDEO_RENDER_TYPE.EASY_VIDEO_RENDER_TYPE_GDI,
EASY_VIDEO_SCALE_MODE.EASY_VIDEO_MODE_LETTERBOX, EASY_STREAM_LINK_MODE.EASY_STREAM_LINK_TCP,
Convert.ToInt32(comboBox1.Text), 0, 1024 * 1024, 1000000);
