上面咱们来解说一下对于SkeyeExPlayer接口的调用，次要分为C++和C#两种语言，C++也能够基于VC和QT进行开发，C++以VC MFC框架为例进行解说，C#以Winform框架为例进行解说。
VC开发SkeyeExPlayer
首先建一个基于MFC Dialog的工程，取名叫SkeyeExPlayer，对于界面逻辑的处理过程就不做过多赘述了，大家有趣味的能够去看SkeyeExPlayer我的项目代码；上面咱们解说一下SkeyeExPlayer的调用流程：(1) 关上一个流或文件进行播放
通过SkeyeExPlayer_Open关上一个流或者本地文件，关上当前即播放，不须要调用SkeyeExPlayer_Play办法，调用实现后，留神，比方拉网络流的时候，因为Open函数是非阻塞而立刻返回的，所以，播放过程可能尚未初始化实现，从而获取流的信息可能获取不到，正确的做法是在线程或者计时器外面轮询获取；Open实现后，咱们能够对一些参数进行设置，比方设置OSD和图片叠加，显示模式，音量大小等：// player open file m_player = SkeyeExPlayer_Open(str, m_stcVideoWnd->GetSafeHwnd()); if (m_player) { m_bPlayPause = FALSE; SetTimer(TIMER_ID_PROGRESS, 1000, NULL); m_bOpening = TRUE; //字幕和图片叠加 // // SkeyeExPlayer_SetLogo 设置台标/LOGO // player - 指向 SkeyeExPlayer_Open 返回的 player 对象 // bIsUse - 是否应用水印 1=启用 0=不启用 // ePos - 台标地位：1==leftttop 2==righttop 3==leftbottom 4==rightbottom // eStyle - 水印的格调，见WATERMARK_ENTRY_TYPE申明 // x - 水印左上角地位x坐标 // y - 水印左上角地位y坐标 // width - 宽 // height - 高 // logopath - 水印图片门路 SkeyeExPlayer_SetLogo (m_player, 1, 2, 3, 0, 0, 0, 0, "C:\\Dingshuai\\Project\\Skeyelogo.png"); // SkeyeExPlayer_SetOSD 设置叠加字幕 // player - 指向 SkeyeExPlayer_Open 返回的 player 对象 // bIsUse - 是否应用水印 1=启用 0=不启用 -1=删除 // nMoveType - 挪动类型：0--固定地位，1--从左往右，2--从右往左， // R,G,B - 字体色彩对应三个重量红绿蓝0-255 // x - 字幕显示左上角地位x坐标 // y - 字幕显示左上角地位y坐标 // weight - 字体权重，见如下申明 // /* Font Weights */ // #define FW_DONTCARE 0 // #define FW_THIN 100 // #define FW_EXTRALIGHT 200 // #define FW_LIGHT 300 // #define FW_NORMAL 400 // #define FW_MEDIUM 500 // #define FW_SEMIBOLD 600 // #define FW_BOLD 700 // #define FW_EXTRABOLD 800 // #define FW_HEAVY 900 // #define FW_ULTRALIGHT FW_EXTRALIGHT // #define FW_REGULAR FW_NORMAL // #define FW_DEMIBOLD FW_SEMIBOLD // #define FW_ULTRABOLD FW_EXTRABOLD // #define FW_BLACK FW_HEA // width - 宽 // height - 高 // fontname - 字体名称，如“宋体”“楷体”“隶书”“华文行楷”...... // tittleContent - OSD显示内容 SkeyeExPlayer_SetOSD (m_player, 1, 1, 0, 255, 0, 700, 100, 200, 0, -29, "隶书", "你说你爱了不该爱的人，你的心中满是创痕！"); }(2) 暂停和单步播放
void CplayerDlg::OnBnClickedBtnPause(){ // TODO: 在此增加控件告诉解决程序代码 if (!m_bPlayPause) SkeyeExPlayer_Pause(m_player); else SkeyeExPlayer_Play(m_player); m_bPlayPause = !m_bPlayPause; CSkinButton* pBtn = (CSkinButton*)GetItemByName(_T("Pause")); if(pBtn) { if (m_bPlayPause) { pBtn->SetBtnText(_T("播放")); } else { pBtn->SetBtnText(_T("暂停")); } }}void CplayerDlg::OnBnClickedBtnPlayByFrame(){ // TODO: 在此增加控件告诉解决程序代码 // SkeyeExPlayer_StepPlay(m_player); m_bPlayPause = TRUE; CSkinButton* pBtn = (CSkinButton*)GetItemByName(_T("Pause")); if(pBtn) { if (m_bPlayPause) { pBtn->SetBtnText(_T("播放")); } else { pBtn->SetBtnText(_T("暂停")); } }}这里间接调用即可，不做过多赘述。
(3) 快放和慢放
void CplayerDlg::OnBnClickedBtnRatePlay(){ int nRate = 0; switch(m_speedRate) { case SPEED_SLOW_X4: nRate = 25; break; case SPEED_SLOW_X2: nRate = 50; break; case SPEED_NORMAL: nRate = 100; break; case SPEED_FAST_X2: nRate = 200; break; case SPEED_FAST_X4: nRate = 300; break; case SPEED_FAST_X8: nRate = 400; break; case SPEED_FAST_X16: nRate = 500; break; case SPEED_FAST_X64: nRate = 600; break; } SkeyeExPlayer_Setparam(m_player, Skeye_PARAM_PLAY_SPEED, &nRate);}目前定义慢放范畴为2倍和4倍，快放范畴为2，4，8，16，64倍，超过这个范畴则无显著反馈或者意义。
(4) 抓图接口调用
void CplayerDlg::OnBnClickedBtnSnapshot(){ // TODO: 在此增加控件告诉解决程序代码 // TCHAR sPath[512]; memset(sPath, 0x00, sizeof(TCHAR) * 512); GetWorkDirectory(sPath, 512); int nPathLen = _tcslen(sPath); if ((sPath[nPathLen - 1] != '/' && sPath[nPathLen - 1] != '\\')) { sPath[nPathLen] = '\\'; } unsigned int timestamp = (unsigned int)time(NULL); time_t tt = timestamp; struct tm _time; ::localtime_s(&_time, &tt); char szTime[64] = { 0, }; strftime(szTime, 32, "\\pic_%Y%m%d%H%M%S.jpg", &_time); CString strTime = (CString)szTime; CString sScreenPath = _T(""); sScreenPath.Format(_T("%s%s"), sPath, _T("ScreenShot")); bool bSec = EnsureDirExist(sScreenPath); sScreenPath += strTime; USES_CONVERSION; SkeyeExPlayer_Snapshot(m_player, T2A(sScreenPath), 0, 0, 1000);}抓图接口间接调用即可，留神保留的门路须要存在，否则，抓图保留将会失败。
(5) 录像接口调用
void CplayerDlg::OnBnClickedBtnRecord(){ // TODO: 在此增加控件告诉解决程序代码 if(!m_player) return ; CSkinButton* pBtn = (CSkinButton*)GetItemByName(_T("Record")); if (!pBtn) { return; } if (!m_bRecording) { pBtn->SetBtnText(_T("进行录像")); TCHAR sPath[512]; memset(sPath, 0x00, sizeof(TCHAR)*512); GetWorkDirectory(sPath, 512); int nRecordPathLen = _tcslen(sPath); if ((sPath[nRecordPathLen - 1] != '/' && sPath[nRecordPathLen - 1] != '\\')) { sPath[nRecordPathLen] = '\\'; } unsigned int timestamp = (unsigned int)time(NULL); time_t tt = timestamp; struct tm _time; ::localtime_s(&_time, &tt); char szTime[64] = { 0, }; strftime(szTime, 32, "\\record_%Y%m%d%H%M%S.mp4", &_time); CString strTime = (CString)szTime; CString sRecordPath = _T(""); sRecordPath.Format(_T("%s%s"), sPath, _T("Record")); bool bSec = EnsureDirExist(sRecordPath); sRecordPath += strTime; UpdateData(TRUE); CString sRecDuration = _T(""); if(m_editRecPieceTime) m_editRecPieceTime->GetWindowText(sRecDuration); int nDuration = _ttoi( sRecDuration.GetBuffer()); //m_SNPlayOcx.SkeyePlayPro_PlayOcx_Record(sRecordPath, m_sRtspUrl, nDuration); //m_SNPlayOcx.SkeyePlayPro_PlayOcx_Record(_T("D:\\test.mp4"), m_sRtspUrl); USES_CONVERSION; SkeyeExPlayer_Record(m_player, T2A(sRecordPath), nDuration); m_lRecordTime = 0;//IDC_STATIC_RECORD_STATUS SetTimer(TIMER_RECORD_STATUS, 300, NULL); } else { pBtn->SetBtnText(_T("录像")); SkeyeExPlayer_Stoprecord(m_player); KillTimer(TIMER_RECORD_STATUS); SkeyeExPlayer_Getparam(m_player, Skeye_PARAM_RECORD_TIME, &m_lRecordTime); SkeyeExPlayer_Getparam(m_player, Skeye_PARAM_RECORD_PIECE_ID, &m_lRecordSliceUp); int thh, tmm, tss = 0; thh = m_lRecordTime / 3600; tmm = (m_lRecordTime % 3600) / 60; tss = (m_lRecordTime % 60); CString sShowRec = _T(""); if (m_lRecordSliceUp > -1) sShowRec.Format(_T("录像已进行 录制工夫：%02d:%02d:%02d 切片ID：%d"), thh, tmm, tss, m_lRecordSliceUp); else sShowRec.Format(_T("录像已进行 录制工夫：%02d:%02d:%02d"), thh, tmm, tss); SetString(4, sShowRec); m_lRecordTime = 0;//IDC_STATIC_RECORD_STATUS } m_bRecording = !m_bRecording;}SkeyePlayPro_PlayOcx_Record接口调用进行录像，SkeyeExPlayer_Stoprecord接口调用进行录像，SkeyeExPlayer_Getparam接口获取录像的工夫和以后录像的PieceId, 具体参数见上一篇文章SkeyeExPlayer接口阐明。

C#我真不善于，故此，只对libSkeyeExPlayer的调用做简略介绍；
首先，创立一个Winform程序（相似于MFC的Dialog程序），而后导入 libSkeyeExPlayer.dll，生成实体类，即可调用接口。
(1) libSkeyeExPlayer.dll接口类化
导入dll，生产类，申明须要用到的参数列表如下：
public enum tagSkeye_PARAM_ID { //++ public // duration & position PARAM_MEDIA_DURATION = 0x1000, PARAM_MEDIA_POSITION, // media detail info PARAM_VIDEO_WIDTH, PARAM_VIDEO_HEIGHT, // video display mode PARAM_VIDEO_MODE, // audio volume control PARAM_AUDIO_VOLUME, // playback speed control PARAM_PLAY_SPEED, // video decode thread count PARAM_DECODE_THREAD_COUNT, // visual effect mode PARAM_VISUAL_EFFECT, // audio/video sync diff PARAM_AVSYNC_TIME_DIFF, // player event callback PARAM_PLAYER_CALLBACK, // audio/video stream PARAM_AUDIO_STREAM_TOTAL, PARAM_VIDEO_STREAM_TOTAL, PARAM_SUBTITLE_STREAM_TOTAL, PARAM_AUDIO_STREAM_CUR, PARAM_VIDEO_STREAM_CUR, PARAM_SUBTITLE_STREAM_CUR, //-- public //++ for adev PARAM_ADEV_RENDER_TYPE = 0x2000, //-- for adev //++ for vdev PARAM_VDEV_RENDER_TYPE = 0x3000, PARAM_VDEV_FRAME_RATE, //-- for vdev //++ for render PARAM_RENDER_UPDATE = 0x4000, PARAM_RENDER_START_PTS, //-- for render };申明SkeyeExPlayer接口如下：
//初始化播放视频 [DllImport("libSkeyeExPlayer.dll", EntryPoint = "SkeyeExPlayer_Open", CallingConvention = CallingConvention.Cdecl)] static extern IntPtr SkeyeExPlayer_Open(string file, IntPtr hwnd); //敞开视频 [DllImport("libSkeyeExPlayer.dll", EntryPoint = "SkeyeExPlayer_Close", CallingConvention = CallingConvention.Cdecl)] static extern void SkeyeExPlayer_Close(IntPtr player); //播放视频 [DllImport("libSkeyeExPlayer.dll", EntryPoint = "SkeyeExPlayer_Play", CallingConvention = CallingConvention.Cdecl)] static extern void SkeyeExPlayer_Play(IntPtr player); //单针播放视频 [DllImport("libSkeyeExPlayer.dll", EntryPoint = "SkeyeExPlayer_StepPlay", CallingConvention = CallingConvention.Cdecl)] static extern void SkeyeExPlayer_StepPlay(IntPtr player); //暂停视频 [DllImport("libSkeyeExPlayer.dll", EntryPoint = "SkeyeExPlayer_Pause", CallingConvention = CallingConvention.Cdecl)] static extern void SkeyeExPlayer_Pause(IntPtr player); //设置时长 [DllImport("libSkeyeExPlayer.dll", EntryPoint = "SkeyeExPlayer_Seek", CallingConvention = CallingConvention.Cdecl)] static extern void SkeyeExPlayer_Seek(IntPtr player, long ms); //设置窗口 [DllImport("libSkeyeExPlayer.dll", EntryPoint = "SkeyeExPlayer_Resize", CallingConvention = CallingConvention.Cdecl)] static extern void SkeyeExPlayer_Resize(IntPtr player, int type, int x, int y, int w, int h); //截图 [DllImport("libSkeyeExPlayer.dll", EntryPoint = "SkeyeExPlayer_Snapshot", CallingConvention = CallingConvention.Cdecl)] static extern int SkeyeExPlayer_Snapshot(IntPtr player, string file, int w, int h, int wait); //设置参数 [DllImport("libSkeyeExPlayer.dll", EntryPoint = "SkeyeExPlayer_Setparam", CallingConvention = CallingConvention.Cdecl)] static extern void SkeyeExPlayer_Setparam(IntPtr player, uint id, ref IntPtr param); //失去参数 [DllImport("libSkeyeExPlayer.dll", EntryPoint = "SkeyeExPlayer_Getparam", CallingConvention = CallingConvention.Cdecl)] static extern void SkeyeExPlayer_Getparam(IntPtr player, uint id, ref IntPtr param);申明一个指针变量用于寄存播放器指针：
private IntPtr mPlayer;创立一个按钮，点击音讯解决：
private void button1_Click(object sender, EventArgs e) { SkeyeExPlayer_Open("rtmp://live.hkstv.hk.lxdns.com/live/hks", panel1.Handle); }其中，panel1是创立的一个pannel，用于显示视频的窗口；
这样，其余接口调用也相似，具体可参考C++的调用流程，这里不做过多赘述；
