集成说明
Ø Unity3D接口和调用demo，参见：SmartPlayerWindowsMono.cs
Ø SmartU3dAndroidPlayer\Assets\Plugins\x86和SmartU3dAndroidPlayer\Assets\Plugins\x86_64下相关库到工程：

n nt_base_code_define.cs加入到工程；
n smart_player_define.cs 加入工程；
n smart_player_sdk.cs加入工程。
Ø 如需集成到自己系统测试，请用大牛直播SDK的app name, windows测试app name：SmartPlayer .
调用时序(V2)
Windows调用时序，可参照Windows C#调用SDK调用说明(参见“视沃科技-Windows-SDK集成说明.pdf”)，此处不再赘述。
调用流程：
1. 开始播放的时候，调用OpenPlayer()，完成PlayerInit和PlayerOpen操作，并设置eventcallback和videoframecallback，并完成相关参数配置，设置YUV回调输出，调用PlayerStart，完成播放端的启动：
public void Play()
{
if (is_running)
{
Debug.Log("已经在播放。。");
return;
}
lock (frame_lock_)
{
cur_video_frame_ = null;
}
//获取输入框的url
string url = input_url_.text.Trim();
if (!url.StartsWith("rtmp://") && !url.StartsWith("rtsp://"))
{
videoUrl = "rtmp://live.hkstv.hk.lxdns.com/live/hks";
}
else
{
videoUrl = url;
}
OpenPlayer();
if (player_handle_ == IntPtr.Zero)
return;
//设置播放URL
NTSmartPlayerSDK.NT_SP_SetURL(player_handle_, videoUrl);
/* ++ 播放前参数配置可加在此处 ++ */
NTSmartPlayerSDK.NT_SP_SetBuffer(player_handle_, play_buffer_time_); //设置buffer time
int is_using_tcp = 1; //TCP模式
NTSmartPlayerSDK.NT_SP_SetRTSPTcpMode(player_handle_, is_using_tcp);
NTSmartPlayerSDK.NT_SP_SetMute(player_handle_, is_mute_ ? 1 : 0); //是否启动播放的时候静音
int is_fast_startup = 1;
NTSmartPlayerSDK.NT_SP_SetFastStartup(player_handle_, is_fast_startup); //设置快速启动模式
NTSmartPlayerSDK.NT_SP_SetLowLatencyMode(player_handle_, is_low_latency_ ? 1 : 0); //设置是否启用低延迟模式
//设置旋转角度(设置0， 90， 180， 270度有效，其他值无效)
NTSmartPlayerSDK.NT_SP_SetRotation(player_handle_, rotate_degrees);
// 设置上传下载报速度
int is_report = 0;
int report_interval = 1;
NTSmartPlayerSDK.NT_SP_SetReportDownloadSpeed(player_handle_, is_report, report_interval);
/* -- 播放前参数配置可加在此处 -- */
//video frame callback (YUV/RGB)
video_frame_call_back_ = new SP_SDKVideoFrameCallBack(NT_SP_SetVideoFrameCallBack);
NTSmartPlayerSDK.NT_SP_SetVideoFrameCallBack(player_handle_, (Int32)NT.NTSmartPlayerDefine.NT_SP_E_VIDEO_FRAME_FORMAT.NT_SP_E_VIDEO_FRAME_FROMAT_I420, window_handle_, video_frame_call_back_);
UInt32 flag = NTSmartPlayerSDK.NT_SP_StartPlay(player_handle_);
if (flag == DANIULIVE_RETURN_OK)
{
is_need_get_frame_ = true;
Debug.Log("播放成功");
}
else
{
is_need_get_frame_ = false;
Debug.LogError("播放失败");
}
is_running = true;
}
private void OpenPlayer()
{
window_handle_ = IntPtr.Zero;
UInt32 isInited = NT.NTSmartPlayerSDK.NT_SP_Init(0, IntPtr.Zero);
if (isInited != 0)
{
Debug.LogError("调用NT_SP_Init失败.." + isInited.ToString());
return;
}
if (player_handle_ == IntPtr.Zero)
{
player_handle_ = new IntPtr();
UInt32 ret_open = NTSmartPlayerSDK.NT_SP_Open(out player_handle_, window_handle_, 0, IntPtr.Zero);
if (ret_open != 0)
{
player_handle_ = IntPtr.Zero;
Debug.LogError("调用NT_SP_Open失败..");
return;
}
}
event_call_back_ = new SP_SDKEventCallBack(NT_SP_SDKEventCallBack);
NTSmartPlayerSDK.NT_SP_SetEventCallBack(player_handle_, window_handle_, event_call_back_);
// 异步回调功能
sdk_video_frame_call_back_ = new SetVideoFrameCallBack(SDKVideoFrameCallBack);
sdk_event_call_back_ = new SetEventCallBack(SDKEventCallBack);
}
2. Video frame实时处理并绘制：
开始播放后，daniulive直播播放端SDK回调yuv数据及相关信息，unity3d获取到数据信息后，调用InitYUVTexture()，完成初始化工作，调用UpdateYUVTexture()实现数据实时刷新，当数据信息发生变化时，会二次调用InitYUVTexture()，完成初始化。
3. 停止播放：
private void ClosePlayer()
{
is_need_get_frame_ = false;
is_need_init_texture_ = false;
if (player_handle_ == IntPtr.Zero)
{
return;
}
UInt32 flag = NTSmartPlayerSDK.NT_SP_StopPlay(player_handle_);
if (flag == DANIULIVE_RETURN_OK)
{
Debug.Log("停止成功");
}
else
{
Debug.LogError("停止失败");
}
NTSmartPlayerSDK.NT_SP_UnInit();
player_handle_ = IntPtr.Zero;
is_running = false;
}

{

}
String t_show_str = "";
