AnyChat（全名叫Anychat SDK），也叫音視頻互動開發(fā)平臺；是一套跨平臺的即時通訊解決方案，基于先進的H.264視頻編碼標準、AAC音頻編碼標準與P2P技術(shù)，整合了佰銳科技在音視頻編碼、多媒體通訊領(lǐng)域領(lǐng)先的開發(fā)技術(shù)和豐富的產(chǎn)品經(jīng)驗而設(shè)計的高質(zhì)量、寬適應(yīng)性、分布式、模塊化的網(wǎng)絡(luò)音視頻互動平臺。

可以進行雙人或多人的語音實時通話，支持Windows、Web、Android、iOS、Mac、Linux等跨平臺通信。

所提供的SDK支持C++、Delphi、Java、C#、VB、object-c等多種語音開發(fā)。

AnyChat包括音頻視頻錄制，拍照，服務(wù)器錄像，文字聊天，文件發(fā)送等多種功能。

界面如下

調(diào)用流程：

　　1.在所要監(jiān)聽的類中調(diào)用重載WndProc方法，實現(xiàn)windows消息的監(jiān)聽。

/// <summary>/// 重載/// </summary>/// <param name="m"></param>protected override void WndProc(ref Message m){if (m.Msg == AnyChatCoreSDK.WM_GV_CONNECT){//客戶端連接服務(wù)器，表示是否連接成功int succed = m.WParam.ToInt32();//連接服務(wù)器成功if (succed == 1){//登錄服務(wù)器(在WndProc中的獲取方法回調(diào)結(jié)果。參數(shù)：AnyChatCoreSDK.WM_GV_LOGINSYSTEM)int ret = AnyChatCoreSDK.Login(PublicMembers.g_Name, "", 0);}else{PublicMembers.ShowRightTip("登錄失敗。錯誤代碼：" + succed, "");}}else if (m.Msg == AnyChatCoreSDK.WM_GV_LOGINSYSTEM){//客戶端登錄系統(tǒng)，wParam（INT）表示自己的用戶ID號int userid = m.WParam.ToInt32();if (m.LParam.ToInt32() == 0){m_myUserID = userid;//進入房間(在WndProc中的獲取方法回調(diào)結(jié)果。參數(shù)：AnyChatCoreSDK.WM_GV_ENTERROOM)int ret = AnyChatCoreSDK.EnterRoom(m_RoomID, "", 0);}else{MessageBox.Show("登錄服務(wù)器失敗，代碼出錯為：" + m.LParam.ToInt32(), "警告");}}else if (m.Msg == AnyChatCoreSDK.WM_GV_ENTERROOM){//客戶端進入房間if (m.LParam.ToInt32() == 0){//綁定本機視頻窗口 -1代表自己int ret = AnyChatCoreSDK.SetVideoPos(-1, picLocalVideo.Handle, 0, 0, picLocalVideo.Width, picLocalVideo.Height);//開啟本地視頻 -1代表自己ret = AnyChatCoreSDK.UserCameraControl(-1, true);//開啟本地聲音 -1代表自己ret = AnyChatCoreSDK.UserSpeakControl(-1, true);}else{MessageBox.Show("申請進入房間失敗，出錯代碼為：" + m.LParam.ToInt32(), "警告");}}else if (m.Msg == AnyChatCoreSDK.WM_GV_ONLINEUSER){//收到當前房間的在線用戶信息，進入房間后觸發(fā)一次int usrcnt = m.WParam.ToInt32();int cnt = 0;//在線用戶數(shù)量AnyChatCoreSDK.GetOnlineUser(null, ref cnt);//獲取在線用戶數(shù)量int[] userArr = new int[cnt];//在線用戶ＩＤAnyChatCoreSDK.GetOnlineUser(userArr, ref cnt);//獲取在線用戶ID數(shù)組}else if (m.Msg == AnyChatCoreSDK.WM_GV_LINKCLOSE){//客戶端掉線處理}else if (m.Msg == AnyChatCoreSDK.WM_GV_USERATROOM){//用戶進入（離開）房間，wParam（INT）表示用戶ID號、//用戶IDint userID = m.WParam.ToInt32();//發(fā)生狀態(tài)int boEntered = m.LParam.ToInt32();if (boEntered == 1){//進入房間m_others.Add(userID);StartVideo(userID);}else{//退出房間m_others.Remove(userID);EndVideo(userID);}}base.WndProc(ref m);}

2.初始化AnyChat的SDK

//設(shè)置回調(diào)函數(shù)SystemSetting.Text_OnReceive = new TextReceivedHandler(Received_CallBack);//文本回調(diào)涵數(shù)SystemSetting.TransBuffer_OnReceive = new TransBufferReceivedHandler(Received_TransBuffer);//透明通道傳輸回調(diào)SystemSetting.TransFile_OnReceive = new TransFileReceivedHandler(Received_TransFile);//文件傳輸回調(diào)SystemSetting.TransRecord_OnReceive = new TransRecordHandler(File_CallBack);//拍照錄像回調(diào)函數(shù)//初始化SystemSetting.Init(this.Handle);//設(shè)置內(nèi)核參數(shù) 設(shè)置保存路徑int ret = 0;ret = AnyChatCoreSDK.SetSDKOption(AnyChatCoreSDK.BRAC_SO_RECORD_TMPDIR, Application.StartupPath, Application.StartupPath.Length);ret = AnyChatCoreSDK.SetSDKOption(AnyChatCoreSDK.BRAC_SO_SNAPSHOT_TMPDIR, Application.StartupPath, Application.StartupPath.Length);

3.連接AnyChat服務(wù)器。使用AnyChat功能必須先連接并登錄AnyChat服務(wù)器。執(zhí)行連接操作后會觸發(fā)windows消息回調(diào) AnyChatCoreSDK.WM_GV_CONNECT

//登錄AnyChat (IP從配置文件中獲取)string IP = XmlHelper.GetXmlAttribute(PublicMembers.Config, "http://Configuration//IP", "value").Value;//連接服務(wù)器(在WndProc中的獲取方法回調(diào)結(jié)果。參數(shù)：AnyChatCoreSDK.WM_GV_CONNECT)ret = AnyChatCoreSDK.Connect(IP, 8906);

4.登錄AnyChat服務(wù)器。執(zhí)行連接操作后會觸發(fā)windows消息回調(diào) AnyChatCoreSDK.WM_GV_LOGINSYSTEM

//登錄服務(wù)器(在WndProc中的獲取方法回調(diào)結(jié)果。參數(shù)：AnyChatCoreSDK.WM_GV_LOGINSYSTEM)int ret = AnyChatCoreSDK.Login(PublicMembers.g_Name, "", 0);

5.服務(wù)器登錄成功后進入指定房間，只有在同一個房間內(nèi)的用戶才可以進行視頻音頻交互。

//進入房間(在WndProc中的獲取方法回調(diào)結(jié)果。參數(shù)：AnyChatCoreSDK.WM_GV_ENTERROOM)int ret = AnyChatCoreSDK.EnterRoom(m_RoomID, "", 0);

6.打開，關(guān)閉音頻視頻

//綁定本機視頻窗口 -1代表自己，通過指定userId來綁定視頻窗口int ret = AnyChatCoreSDK.SetVideoPos(-1, picLocalVideo.Handle, 0, 0, picLocalVideo.Width, picLocalVideo.Height);//開啟本地視頻 -1代表自己ret = AnyChatCoreSDK.UserCameraControl(-1, true);//開啟本地聲音 -1代表自己ret = AnyChatCoreSDK.UserSpeakControl(-1, true);

7.發(fā)送文件，文字，錄制等操作

//發(fā)送文字int ret = AnyChatCoreSDK.SendTextMessage(-1, true, text, length);//發(fā)送文件 filepath：文件路徑int taskId = 0;int flag = AnyChatCoreSDK.TransFile(userId, filepath, 1, 0, 0, ref taskId);//開啟聲音int ret = AnyChatCoreSDK.UserSpeakControl(userId, true);//關(guān)閉聲音int ret = AnyChatCoreSDK.UserSpeakControl(userId, false);//開啟視頻int ret = AnyChatCoreSDK.UserCameraControl(userId, true);//關(guān)閉視頻int ret = AnyChatCoreSDK.UserCameraControl(userId, false);//開始錄像ulong flag = 0;//0為錄制視頻 1為錄制音頻int ret = AnyChatCoreSDK.StreamRecordCtrl(userId, true, flag, 0);//停止錄像ulong flag = 0;//0為錄制視頻 1為錄制音頻int ret = AnyChatCoreSDK.StreamRecordCtrl(userId, false, flag, 0);//拍照AnyChatCoreSDK.SnapShot(userId, 1, 1);
