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。

{nPos = m_dbBreakPtA;}
}
#endif
if (m_totalDuration>0)
{SkeyeExPlayer_Seek(m_player, nPos*1000);
}
}
}c. 音量调节进度条 OnHScroll 音讯解决

{int nValue = m_sliderSound->GetPos();
nValue -= 255;
SkeyeExPlayer_Setparam(m_player, Skeye_PARAM_AUDIO_VOLUME, &nValue);
}
- C# 开发 SkeyeExPlayer
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；
