本文以大牛直播SDK的Windows平台为例大概介绍下如何实现Unity环境下的录制Linux、Android、iOS平台实现也类似都是原生接口然后对接下就好 开始录像
因为涉及到可能同时录制多路的场景考虑到磁盘读写IOWindows平台一般不建议多录录制录像的话需要考虑的是设置好文件录制规则比如是否录制纯音频或纯视频、单个录制文件大小、文件录制目录等并设置录像回调事件
/** SmartPlayerWinMono.cs* Author: daniusdk.com*/
private void StartRecorder(int sel)
{Debug.Log(StartRecorder, sel: sel);if (videoctrl[sel].is_recording_){Debug.Log(StartRecorder, already started.. sel: sel);return;}if (!videoctrl[sel].is_playing_){if (!OpenPlayerHandle(sel)){Debug.LogError(call OpenPlayerHandle failed..);return;}}bool is_rec_video true;bool is_rec_audio true;NTSmartPlayerSDK.NT_SP_SetRecorderVideo(videoctrl[sel].player_handle_, is_rec_video ? 1 : 0);NTSmartPlayerSDK.NT_SP_SetRecorderAudio(videoctrl[sel].player_handle_, is_rec_audio ? 1 : 0);String rec_dir D:\\Rec; //录像目录可自行指定String rec_name_file_prefix_ daniu sel.ToString();UInt32 max_file_size 200 * 1024; // 单位是KByte, 默认200MBbool is_append_date true;bool is_append_time true;bool is_audio_transcode_aac true;UInt32 ret NTSmartPlayerSDK.NT_SP_SetRecorderDirectory(videoctrl[sel].player_handle_, rec_dir);if (NT.NTBaseCodeDefine.NT_ERC_OK ! ret){Debug.LogError(设置录像目录失败请确保目录存在且是英文目录);return;}NTSmartPlayerSDK.NT_SP_SetRecorderFileMaxSize(videoctrl[sel].player_handle_, max_file_size);NT_SP_RecorderFileNameRuler rec_name_ruler new NT_SP_RecorderFileNameRuler();rec_name_ruler.type_ 0;rec_name_ruler.file_name_prefix_ rec_name_file_prefix_;rec_name_ruler.append_date_ is_append_date ? 1 : 0;rec_name_ruler.append_time_ is_append_time ? 1 : 0;NTSmartPlayerSDK.NT_SP_SetRecorderFileNameRuler(videoctrl[sel].player_handle_, ref rec_name_ruler);NTSmartPlayerSDK.NT_SP_SetRecorderAudioTranscodeAAC(videoctrl[sel].player_handle_, is_audio_transcode_aac ? 1 : 0);videoctrl[sel].record_call_back_ new SP_SDKRecorderCallBack(NT_SP_SDKRecorderCallBack);NTSmartPlayerSDK.NT_SP_SetRecorderCallBack(videoctrl[sel].player_handle_, IntPtr.Zero, videoctrl[sel].record_call_back_);videoctrl[sel].set_record_call_back_ new VideoControl.SetRecordCallBack(RecordCallBack);if (NT.NTBaseCodeDefine.NT_ERC_OK ! NTSmartPlayerSDK.NT_SP_StartRecorder(videoctrl[sel].player_handle_)){Debug.LogError(call NT_SP_StartRecorder failed..);return;}videoctrl[sel].is_recording_ true;
}
其中OpenPlayerHandle()实现如下通过调用Open()接口生成个player实例句柄然后后续针对这个句柄操作即可如果同一个实例句柄下需要播放直接调用播放接口就好了。
private bool OpenPlayerHandle(int sel)
{if (videoctrl[sel].player_handle_ ! IntPtr.Zero)return true;window_handle_ IntPtr.Zero;if (videoctrl[sel].player_handle_ IntPtr.Zero){videoctrl[sel].player_handle_ new IntPtr();UInt32 ret_open NTSmartPlayerSDK.NT_SP_Open(out videoctrl[sel].player_handle_, window_handle_, 0, IntPtr.Zero);if (ret_open ! 0){videoctrl[sel].player_handle_ IntPtr.Zero;Debug.LogError(call NT_SP_Open failed, sel: sel);return false;}}videoctrl[sel].event_call_back_ new SP_SDKEventCallBack(NT_SP_SDKEventCallBack);NTSmartPlayerSDK.NT_SP_SetEventCallBack(videoctrl[sel].player_handle_, window_handle_, videoctrl[sel].event_call_back_);videoctrl[sel].sdk_event_call_back_ new VideoControl.SetEventCallBack(SDKEventCallBack);if (IntPtr.Zero videoctrl[sel].player_handle_)return false;/* 播放前参数配置可加在此处 */int play_buffer_time_ 100;NTSmartPlayerSDK.NT_SP_SetBuffer(videoctrl[sel].player_handle_, play_buffer_time_); //设置buffer timeint is_using_tcp 1; //TCP模式NTSmartPlayerSDK.NT_SP_SetRTSPTcpMode(videoctrl[sel].player_handle_, is_using_tcp);int timeout 10;NTSmartPlayerSDK.NT_SP_SetRtspTimeout(videoctrl[sel].player_handle_, timeout);int is_auto_switch_tcp_udp 1;NTSmartPlayerSDK.NT_SP_SetRtspAutoSwitchTcpUdp(videoctrl[sel].player_handle_, is_auto_switch_tcp_udp);Boolean is_mute_ false;NTSmartPlayerSDK.NT_SP_SetMute(videoctrl[sel].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(videoctrl[sel].player_handle_, is_fast_startup); //设置快速启动模式Boolean is_low_latency_ false;NTSmartPlayerSDK.NT_SP_SetLowLatencyMode(videoctrl[sel].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)int rotate_degrees 0;NTSmartPlayerSDK.NT_SP_SetRotation(videoctrl[sel].player_handle_, rotate_degrees);int volume 100;NTSmartPlayerSDK.NT_SP_SetAudioVolume(videoctrl[sel].player_handle_, volume); //设置播放音量, 范围是[0, 100], 0是静音100是最大音量, 默认是100// 设置上传下载报速度int is_report 0;int report_interval 2;NTSmartPlayerSDK.NT_SP_SetReportDownloadSpeed(videoctrl[sel].player_handle_, is_report, report_interval);//设置播放URLNTSmartPlayerSDK.NT_SP_SetURL(videoctrl[sel].player_handle_, videoctrl[sel].playback_url_);/* -- 播放前参数配置可加在此处 -- */return true;
}
录像回调事件如下
public void RecordCallBack(UInt32 status, [MarshalAs(UnmanagedType.LPStr)] String file_name, int sel)
{if (status 1) //status 1:表示开始写一个新录像文件{Debug.Log(RecordCallBack, 开始一个新的录像文件, sel: sel status: status , filename: file_name);}else if (status 2) //status 2:表示已经写好一个录像文件{Debug.Log(RecordCallBack, 已生成一个录像文件, sel: sel status: status , filename: file_name);}
}
停止录像
private void StopRecorder(int sel)
{Debug.Log(StopRecorder, sel: sel);if (videoctrl[sel].player_handle_ IntPtr.Zero){return;}NTSmartPlayerSDK.NT_SP_StopRecorder(videoctrl[sel].player_handle_);videoctrl[sel].is_recording_ false;if (!videoctrl[sel].is_playing_){NTSmartPlayerSDK.NT_SP_Close(videoctrl[sel].player_handle_);videoctrl[sel].player_handle_ IntPtr.Zero;}
}
以上是Unity平台RTMP或RTSP播放端录像相关接口设计和调用实例感兴趣的开发者可以参考。
