Question

我的程序使用AxShockwaveFlash组件作为流播放器。问题是我的代码适用于大多数流提供者（livestream，ustream，own3d.tv），但Justin.TV的播放器有些问题。

在继续讨论实际问题之前，让我总结一下我的代码;

继承FlashControl - 这允许我覆盖flashplayer的内置菜单：

public class FlashPlayer : AxShockwaveFlashObjects.AxShockwaveFlash // Customized Flash Player.
    {
        private const int WM_MOUSEMOVE = 0x0200;
        private const int WM_MOUSEWHEEL = 0x020A;
        private const int WM_LBUTTONDOWN = 0x0201;
        private const int WM_LBUTTONUP = 0x0202;
        private const int WM_LBUTTONDBLCLK = 0x0203; 
        private const int WM_RBUTTONDOWN = 0x0204;
        private const int WM_RBUTTONUP = 0x0205;                      

        public new event MouseEventHandler DoubleClick;
        public new event MouseEventHandler MouseDown;
        public new event MouseEventHandler MouseUp;
        public new event MouseEventHandler MouseMove;

        public FlashPlayer():base()
        {
            this.HandleCreated += FlashPlayer_HandleCreated;
        }

        void FlashPlayer_HandleCreated(object sender, EventArgs e)
        {
            this.AllowFullScreen = "true";
            this.AllowNetworking = "all";
            this.AllowScriptAccess = "always";
        }

        protected override void WndProc(ref Message m) // Override's the WndProc and disables Flash activex's default right-click menu and if exists shows the attached ContextMenuStrip.
        {
            if (m.Msg == WM_LBUTTONDOWN)
            {
                if (this.MouseDown != null) this.MouseDown(this, new MouseEventArgs(System.Windows.Forms.MouseButtons.Left, 1, Cursor.Position.X, Cursor.Position.Y, 0));
            }
            else if (m.Msg == WM_LBUTTONUP)
            {
                if (this.MouseUp != null) this.MouseUp(this, new MouseEventArgs(System.Windows.Forms.MouseButtons.None, 0, Cursor.Position.X, Cursor.Position.Y, 0));
            }
            else if (m.Msg == WM_MOUSEMOVE)
            {
                if (this.MouseMove != null) this.MouseMove(this, new MouseEventArgs(System.Windows.Forms.MouseButtons.None, 0, Cursor.Position.X, Cursor.Position.Y, 0));
            }
            else if (m.Msg == WM_RBUTTONDOWN)
            {
                if (this.ContextMenuStrip != null) this.ContextMenuStrip.Show(Cursor.Position.X, Cursor.Position.Y);
                m.Result = IntPtr.Zero;
                return;
            }
            else if (m.Msg == WM_LBUTTONDBLCLK)
            {
                if (this.DoubleClick != null) this.DoubleClick(this, new MouseEventArgs(System.Windows.Forms.MouseButtons.Left, 2, Cursor.Position.X, Cursor.Position.Y, 0));
                m.Result = IntPtr.Zero;
                return;
            }

            base.WndProc(ref m);
        }
    }

播放器窗口代码:(播放器是FlashPlayer的一个实例）

private void Player_Load(object sender, EventArgs e) 
        {
            try
            {
                this.Text = string.Format("Stream: {0}", this._stream.Name); // set the window title.
                this.Player.LoadMovie(0, this._stream.Movie); // load the movie.

                if (this._stream.ChatAvailable && Settings.Instance.AutomaticallyOpenChat) this.OpenChatWindow();
            }
            catch (Exception exc)
            {
                // log stuff.
            }
        }

所以这对livestream.com，ustream.com，own3d.tv很有用，但是当它来到justin.tv的播放器时，我得到1337错误（嵌入代码无效）。所以我试图ask them寻求支持，但无法得到有效答案。

_stream.movie变量实际上包含流源的有效URL，如;

http://cdn.livestream.com/grid/LSPlayer.swf?channel=%slug%&autoPlay=true（直播样本）

或

http://www.justin.tv/widgets/live_embed_player.swf?channel=%slug%&auto_play=true&start_volume=100（justin.tv示例）

试图对justin.tv的'channel =％slug％＆amp; auto_play = true＆amp; start_volume = 100'部分进行urlencode，但这也不起作用。

所以我开始尝试一些解决方法，首先我想设置控件的flashVars变量。

但是我有一个奇怪的问题，每当我尝试设置flashVars变量时，它永远不会被设置。我找到了关于这个问题的示例截图;

所以如果我能够设置flashVariables可能是我可以解决justin.tv播放器的错误。顺便说一句，我也尝试使用Player.SetVariable（键，值）设置变量 - 这也不起作用。

注意：

我正在运行.net 4.0客户端配置文件。
使用Flash10l.ocx。
使用“aximp.exe -source”生成了AxShockwaveFlashObjects.dll，ShockwaveFlashObjects.dll包装器C：\ WINDOWS \ system32 \ Macromed \ Flash \ Flash10l.ocx“

Answer 1

我最近遇到了使justin.tv工作的问题，但最终它就像

一样简单

axShockwaveFlash1.FlashVars = "auto_play=true&channel=adventuretimed&start_volume=25";
axShockwaveFlash1.Movie = "http://www.justin.tv/widgets/live_embed_player.swf";

它完美无缺

设置AxShockwaveFlash的FlashVars
