1、C#新增DirectShow庫

新增引用，選擇“瀏覽”，新增Windows/System32/quartz.dll，引用中自動增加QuartzTypeLib。

2、程式碼如下：

using System;

using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
//
using QuartzTypeLib;//引用DirectShow類庫


namespace DirectShow
{
    public partial class FormMain : Form
    {
        //窗體樣式
        public const int WS_BORDER = 0x00800000;
        public const int WS_CAPTION = 0x00C00000;
        public const int WS_CHILD = 0x40000000;
        //
        QuartzTypeLib.FilgraphManager m_FilterManager;//管理器
        QuartzTypeLib.IVideoWindow m_VideoWindow;//視訊窗體
        QuartzTypeLib.IMediaEvent m_MediaEvent;//媒體事件
        QuartzTypeLib.IMediaEventEx m_MediaEventEx;//媒體事件擴充套件
        QuartzTypeLib.IMediaPosition m_MediaPos;//媒體當前位置
        QuartzTypeLib.IMediaControl m_MediaCtrl;//媒體控制器


        public FormMain()
        {
            InitializeComponent();
        }


        private void Form1_Load(object sender, EventArgs e)
        {
            m_FilterManager = new QuartzTypeLib.FilgraphManager();//
            m_FilterManager.RenderFile("f:/768x576.avi");//設定待播放檔案
            m_VideoWindow = m_FilterManager as QuartzTypeLib.IVideoWindow;//設定播放窗體
            m_VideoWindow.Owner = (int)(this.panelMain.Handle);
            m_VideoWindow.WindowStyle &= ~WS_BORDER;
            m_VideoWindow.SetWindowPosition(0, 0, panelMain.Width,panelMain.Height);
            //
            m_MediaEvent = m_FilterManager as QuartzTypeLib.IMediaEvent;//設定媒體事件
            m_MediaEventEx = m_FilterManager as QuartzTypeLib.IMediaEventEx;//設定媒體事件擴充套件
            m_MediaPos = m_FilterManager as QuartzTypeLib.IMediaPosition;//設定媒體位置
            m_MediaCtrl = m_FilterManager as QuartzTypeLib.IMediaControl;//設定媒體控制器
        }


        private void btnOpen_Click(object sender, EventArgs e)
        {
            m_MediaCtrl.Run();
        }


        private void btnStop_Click(object sender, EventArgs e)
        {
            m_MediaCtrl.Stop();
        }
    }
}
