简单来说Unity3D环境下可以直接调用C#的接口封装针对此我们先做了一层封装 nt_publisher_wrapper.cs核心代码如下
初始化和基础参数设置 private bool InitSDK(){if (!is_pusher_sdk_init_){// 设置日志路径(请确保目录存在)String log_path D:\\pulisherlog;NTSmartLog.NT_SL_SetPath(log_path);UInt32 isInited NTSmartPublisherSDK.NT_PB_Init(0, IntPtr.Zero);if (isInited ! 0){Debug.Log(调用NT_PB_Init失败..);return false;}is_pusher_sdk_init_ true;}return true;} public bool OpenPublisherHandle(uint video_option, uint audio_option){if (publisher_handle_ ! IntPtr.Zero){return true;}publisher_handle_count_ 0;if (NTBaseCodeDefine.NT_ERC_OK ! NTSmartPublisherSDK.NT_PB_Open(out publisher_handle_,video_option, audio_option, 0, IntPtr.Zero)){return false;}if (publisher_handle_ ! IntPtr.Zero){pb_event_call_back_ new NT_PB_SDKEventCallBack(PbEventCallBack);NTSmartPublisherSDK.NT_PB_SetEventCallBack(publisher_handle_, IntPtr.Zero, pb_event_call_back_);return true;}else{return false;}} private void SetCommonOptionToPublisherSDK(){if (!IsPublisherHandleAvailable()){Debug.Log(SetCommonOptionToPublisherSDK, publisher handle with null..);return;}CameraInfo camera cameras_[cur_sel_camera_index_];NT_PB_VideoCaptureCapability cap camera.capabilities_[cur_sel_camera_resolutions_index_];SetVideoCaptureDeviceBaseParameter(camera.id_.ToString(), (UInt32)cap.width_, (UInt32)cap.height_);SetFrameRate((UInt32)CalBitRate(edit_key_frame_, cap.width_, cap.height_));SetVideoEncoderType(is_h264_encoder ? 1 : 2);SetVideoQualityV2(CalVideoQuality(cap.width_, cap.height_, is_h264_encoder));SetVideoMaxBitRate((CalMaxKBitRate(edit_key_frame_, cap.width_, cap.height_, false)));SetVideoKeyFrameInterval((edit_key_frame_));if (is_h264_encoder){SetVideoEncoderProfile(1);}SetVideoEncoderSpeed(CalVideoEncoderSpeed(cap.width_, cap.height_, is_h264_encoder));// 音频相关设置SetAuidoInputDeviceId(0);SetPublisherAudioCodecType(1);SetPublisherMute(is_mute);SetInputAudioVolume(Convert.ToSingle(edit_audio_input_volume_));}
预览、停止预览 public bool StartPreview(){if(CheckPublisherHandleAvailable() false)return false;video_preview_image_callback_ new NT_PB_SDKVideoPreviewImageCallBack(SDKVideoPreviewImageCallBack);NTSmartPublisherSDK.NT_PB_SetVideoPreviewImageCallBack(publisher_handle_, (int)NTSmartPublisherDefine.NT_PB_E_IMAGE_FORMAT.NT_PB_E_IMAGE_FORMAT_RGB32, IntPtr.Zero, video_preview_image_callback_);if (NTBaseCodeDefine.NT_ERC_OK ! NTSmartPublisherSDK.NT_PB_StartPreview(publisher_handle_, 0, IntPtr.Zero)){if (0 publisher_handle_count_){NTSmartPublisherSDK.NT_PB_Close(publisher_handle_);publisher_handle_ IntPtr.Zero;}return false;}publisher_handle_count_;is_previewing_ true;return true;}public void StopPreview(){if (is_previewing_ false) return;is_previewing_ false;publisher_handle_count_--;NTSmartPublisherSDK.NT_PB_StopPreview(publisher_handle_);if (0 publisher_handle_count_){NTSmartPublisherSDK.NT_PB_Close(publisher_handle_);publisher_handle_ IntPtr.Zero;}}
开始推送、停止推送 public bool StartPublisher(String url){if (CheckPublisherHandleAvailable() false) return false;if (publisher_handle_ IntPtr.Zero){return false;}if (!String.IsNullOrEmpty(url)){NTSmartPublisherSDK.NT_PB_SetURL(publisher_handle_, url, IntPtr.Zero);}if (NTBaseCodeDefine.NT_ERC_OK ! NTSmartPublisherSDK.NT_PB_StartPublisher(publisher_handle_, IntPtr.Zero)){if (0 publisher_handle_count_){NTSmartPublisherSDK.NT_PB_Close(publisher_handle_);publisher_handle_ IntPtr.Zero;}is_publishing_ false;return false;}publisher_handle_count_;is_publishing_ true;return true;}public void StopPublisher(){if (is_publishing_ false) return;publisher_handle_count_--;NTSmartPublisherSDK.NT_PB_StopPublisher(publisher_handle_);if (0 publisher_handle_count_){NTSmartPublisherSDK.NT_PB_Close(publisher_handle_);publisher_handle_ IntPtr.Zero;}is_publishing_ false;}
相关event事件回调 private void PbEventCallBack(IntPtr handle, IntPtr user_data, UInt32 event_id,Int64 param1,Int64 param2,UInt64 param3,UInt64 param4,[MarshalAs(UnmanagedType.LPStr)] String param5,[MarshalAs(UnmanagedType.LPStr)] String param6,IntPtr param7){String event_log ;switch (event_id){case (uint)NTSmartPublisherDefine.NT_PB_E_EVENT_ID.NT_PB_E_EVENT_ID_CONNECTING:event_log 连接中;if (!String.IsNullOrEmpty(param5)){event_log event_log url: param5;}break;case (uint)NTSmartPublisherDefine.NT_PB_E_EVENT_ID.NT_PB_E_EVENT_ID_CONNECTION_FAILED:event_log 连接失败;if (!String.IsNullOrEmpty(param5)){event_log event_log url: param5;}break;case (uint)NTSmartPublisherDefine.NT_PB_E_EVENT_ID.NT_PB_E_EVENT_ID_CONNECTED:event_log 已连接;if (!String.IsNullOrEmpty(param5)){event_log event_log url: param5;}break;case (uint)NTSmartPublisherDefine.NT_PB_E_EVENT_ID.NT_PB_E_EVENT_ID_DISCONNECTED:event_log 断开连接;if (!String.IsNullOrEmpty(param5)){event_log event_log url: param5;}break;default:break;}if(OnLogEventMsg ! null) OnLogEventMsg.Invoke(event_id, event_log);}
SmartPublishWinMono.cs 调用上述封装的代码即可本地预览的话拿到回调的RGB数据在unity3d上层刷下即可如下图 经测试unity3d下RTMP推送配合RTMP播放端依然可以实现毫秒级延迟的推拉流体验。
