liveserv可以支持同时编码screen,window,camera,mic,movie ，集成本地rtmp服务器，支持共享时缺省推流到本地rtmp服务器，同时支持单独命令进行多路rmtp流推送和多路录制。
1. 客户端模拟
wsclient.exe，使用命令如下
connect <ws uri>
send <connection id> <message>
close <connection id> [<close code:default=1000>] [<close reason>]
show <connection id>
help: Display this help text
quit: Exit the program

connect ws://127.0.0.1:6080  这个端口可以在config.ini里[LiveServ] PORT=6080 配置
wssclient.exe 如果测试 secure websocket，使用wssclient.exe，命令与wsclient相同
connect wss://localhost.xuedianyun.com:6081 这个端口可以在config.ini里[LiveServ] PORT=6081 配置，如果为0，则不启动secure websocket服务

(1)获取liveserv的本地rtmp服务器端口
send 0 get_rtmp_port  ;缺省返回值为1935，可以在liveserv.ini(应用程序名+ini)中配置 RTMP.Port=1935

(2) 媒体共享命令
send 0 mov_start //开始媒体共享，缺省本地推流地址为rtmp://127.0.0.1:1935/live/ms
send 0 mov_start rtmp://127.0.0.1:1935/live/mytest  //开始媒体共享，把共享流推向rtmp://127.0.0.1:1935/live/mytest
send 0 mov_stop  //停止媒体共享
send 0 mov_pause //暂停媒体共享，当前位置暂停
send 0 mov_pause 60 //暂停媒体共享，设置停止位置为60s，resume时，会从60s处继续
send 0 mov_resume   //从暂停状态变成继续共享
send 0 mov_seek 120  //seek 到120秒


（2）屏幕共享命令(scr)
send 0 ss_start //开始屏幕共享，缺省本地推流地址为rtmp://127.0.0.1:1935/live/ss
send 0 ss_stop

send 0 ss_start rtmp://127.0.0.1:1935/live/mytest  //开始屏幕共享，把共享流推向rtmp://127.0.0.1:1935/live/mytest
send 0 ss_stop

send 0 ss_start 100,100,400,200 //共享屏幕(100,100)位置,宽为400，高为200区域，缺省本地推流地址为rtmp://127.0.0.1:1935/live/ss
send 0 ss_stop

send 0 ss_start rtmp://127.0.0.1:1935/live/mytest 100,100,400,200 //共享屏幕(100,100)位置,宽为400，高为200区域，把共享流推向rtmp://127.0.0.1:1935/live/mytest
send 0 ss_stop

如果使用SmartStreamingSDK(配置方式为见后面config.ini说明里[ConfigInfo] use_smart_streaming_sdk=1)，当推流地址不为rtmp://127.0.0.1:1935/live/ss时，自动添加一路推流到rtmp://127.0.0.1:1935/live/ss。
使用SmartStreamingSDK时，start_push,start_record里参数 video=scr 不起作用。使用SmartStreamingSDK做屏幕共享时，如果要推音频，需要先aud_start，再ss_start。如果要静音，设置send 0 set_mic_vol 0，取消静音，则send 0 set_mic_vol 100。


(3)文档共享（窗口共享）(doc)
；相应参数从ds_start.txt读取，ds_start是一个文本文件，第一行保存的是窗口标题，后面各行依次为x坐标，y坐标，宽度，高度
send 0 ds_start //开始文档共享（窗口共享）,缺省本地推流地址为rtmp://127.0.0.1:1935/live/ds
send 0 ds_start rtmp://127.0.0.1:1935/live/mytest  //开始文档共享，把共享流推向rtmp://127.0.0.1:1935/live/mytest
send 0 ds_stop

(3) 音频共享(mic)
；如果先运行了send 0 get_mic，会使用get_mic返回的第一个mic名测试；否则使用 "麦克风 (Conexant SmartAudio HD)"
send 0 aud_start //开始音频,缺省本地推流地址为rtmp://127.0.0.1:1935/live/as
send 0 aud_start /开始音频,把共享流推向rtmp://127.0.0.1:1935/live/mytest
send 0 aud_stop
send 0 get_mic //获取mic列表

(4)摄像头共享
send 0 get_cam
;如果先运行了send 0 get_cam,会使用get_cam返回的第一个摄像头名字，否则使用"Integrated Camera"
send 0 cam_start  //开始摄像头共享，缺省本地推流地址为rtmp://127.0.0.1:1935/live/cs
send 0 cam_stop

send 0 cam_start rtmp://127.0.0.1:1935/live/mytest  //开始摄像头共享,把共享流推向rtmp://127.0.0.1:1935/live/mytest
send 0 cam_stop


(5)录制
录制时，要进行相应的共享，才可能有流。如果要录制camra和mic，需要先audio_start,cam_start，然后start_record
或者先start_record，也要audio_start之后才有对应的audio，cam_start之后才有对应video。如果已经开始了相应的共享，start_record后不指定音视频源，则自动选择已经共享的源，
选择顺序为视频：屏幕共享，窗口共享，摄像头共享，媒体共享； 音频：音频共享，媒体共享;如果不需要音频，可以指定audio=non;不需要视频 video=non

send 0 start_record 0 video=cam audio=mic //视频为摄像头，音频为MIC  （start_record后面的0为录制序号，如果不写，缺省为0)
send 0 start_record 1 video=scr audio=mic //视频为屏幕共享，音频为MIC（start_record后面的0为录制序号，如果不写，缺省为0
send 0 start_record 2 audio=non video=scr //视频为屏幕共享，无音频  (start_record 后面的0为推流序号，如果不写，缺省为0)
send 0 stop_record 0
send 0 stop_record 1
send 0 stop_record 2
send 0 stop_record -1 //停止所有录制

(6) 推流(向外部服务器推流)
向外部推流时，要进行相应的共享，才可能有流。如果要向外部推camra和mic，需要先audio_start,cam_start，然后start_push
或者先start_push，也要audio_start之后才有对应的audio，cam_start之后才有对应video。如果已经开始了相应的共享，start_push后不指定音视频源，则自动选择已经共享的源，
选择顺序为视频：屏幕共享，窗口共享，摄像头共享，媒体共享； 音频：音频共享，媒体共享;如果不需要音频，可以指定audio=non;不需要视频 video=non

send 0 start_push 0 audio=mic video=cam rtmp://myrtmpserver/live/mystream1 //视频为摄像头，音频为MIC  (start_push 后面的0为推流序号，如果不写，缺省为0),
send 0 start_push 1 audio=mic video=scr rtmp://myrtmpserver/live/mystream2 //推第二路流，视频为屏幕共享，音频为MIC  (start_push 后面的0为推流序号，如果不写，缺省为0)
send 0 start_push 2 audio=non video=scr rtmp://myrtmpserver/live/mystream3 //推第三路流，视频为屏幕共享，无音频  (start_push 后面的0为推流序号，如果不写，缺省为0)
send 0 stop_push 0 //停止第一路流
send 0 stop_push 1 //停止第二路流
send 0 stop_push 2 //停止第三路流
send 0 stop_push -1 //停止所有推流


(7)设置编码参数
send 0 set_videoparam cam=640;480;15;45;1000;2000     //设置摄像头共享的编码参数：数字，分号分隔: width;height;fps;keyframe-interval;bit-rate;max-bitrate   如果某一项保留原设置，该项不填写数字
                                                 例如，只修改分辨率：send 0 set_videoparam 640;480;;;;
												 
send 0 set_videoparam scr=640;480;15;45;1000;2000     //设置屏幕共享的编码参数
send 0 set_videoparam doc=640;480;15;45;1000;2000     //设置文档共享的编码参数
send 0 set_videoparam mov=640;480;15;45;1000;2000     //设置媒体共享的编码参数
(8)获取编码参数
send 0 get_videoparam cam   //获取摄像头共享编码参数,其他类型形式相同(scr,mov,doc)返回的参数格式如设置参数：  cam=640;480;15;45;1000;2000     //w;h;fps;keyframe-interval;bit-rate;max-bitrate

(9)设置MIC音量
send 0 set_mic_vol 100  ;0为静音，100为原始音量大小，(0,100)音量减小(100,200]音量提升

(10)获取MIC音量
send 0 get_mic_vol

(11)系统剪贴板,文件相关(保留之前插件功能)
send 0 clipboard_query image    //查询剪贴板里是否有图片
send 0 clipboard_get image      //获取剪贴板里的图片，返回文件格式缺省为jpg
send 0 clipboard_get image jpg  //获取剪贴板里的图片，返回文件格式jpg
send 0 clipboard_get image png  //获取剪贴板里的图片，返回文件格式png
send 0 file_get filename        //获取插件目录下的文件内容
send 0 file_set filename        //设置插件目录下的文件内容

(12)屏幕录制/QAV命令(保留之前插件功能)
send 0 get_mic
send 0 rec_start 麦克风 (Conexant High Definition S
send 0 rec_start 0 ;通过get_mic获取的mic列表的顺序号（0开始）
send 0 rec_stop
send 0 rec_version

send 0 qav_login
send 0 qav_logout
send 0 qav_enter_room
send 0 qav_leave_room

send 0 qav_close_mic
send 0 qav_open_player
send 0 qav_close_player
send 0 qav_mute_audio
send 0 qav_unmute_audio

(13)获取版本信息（在config.ini的[ConfigInfo]，version=项配置），与之前插件兼容
send 0 ss_version
send 0 mov_version
send 0 rec_version

(14)获取配置信息get_config（根据config.ini中配置项名称，直接访问）
send 0 get_config ConfigInfo.use_smart_streaming_sdk //是否使用SmartSDK
send 0 get_config ScrShare.width                     //获取屏幕共享宽度信息


(15)设置配置信息set_config（根据config.ini中配置项名称，直接访问）
send 0 set_config  ConfigInfo.use_smart_streaming_sdk=1 //设置使用SmartSDK
send 0 get_config ScrShare.width=1920                    //设置屏幕共享宽度为1920

数据头后面是data_len字节的数据，根据各个cmd不同，有不同的结构
（1）命令消息
	看ws_data.h中WSCmd_E列举值
	WS_CMD_MOV_START和WS_CMD_SS_START时data为rtmp的URI
	WS_CMD_MOV_SEEK时data为seek的位置，4个字节int类型，单位秒
	WS_CMD_REC_PUSH_AUDIO_DATA时data为音频PCM RAW数据
	WS_CMD_REC_START时data为MIC名字，不传的话只录制speaker
	WS_CMD_FILE_SET时data前256字节为文件名，后面data_len - 256 字节为文件内容
	WS_CMD_FILE_GET时data为文件名
	WS_CMD_KILL_PROCESS时，data前256字节为应用程序名（movserv.exe,ssserv.exe,recserv.exe)
	
（2）返回消息
	看ws_data.h中WSResult_E列举值
	a. WS_RES_MOV_PROPERTY时data为视频参数如下：
	typedef struct tagMovProperty_S
	{
		int32_ws nWidth; //宽
		int32_ws nHeight;//高
		int32_ws nFrameRate;//帧率
		int32_ws nDuration;// 时长
		int32_ws nPos;//开始播放位置，秒
		uint32_ws nFileSize;//文件大小低32位
		int32_ws nFileNameLength;//sFileName字符串长度
		uint32_ws nFileSizeHigh;//文件大小高32位
		int8_ws sFileName[MOV_FILENAME_MAX_LENGTH + 1]; // 播放视频文件名，MOV_FILENAME_MAX_LENGTH=255
	} MovProperty_S;
	
	b. 其他没有data值，看比如WS_RES_MOV_START_SUC是指播放成功
	
	c. WS_RES_CBD_GET_SUC时，data为返回的文件信息
	typedef struct tagCBD_FIlE_S
	{
		int32_ws type; //文件类型，
		int32_ws nlen; //文件长度
		int8_ws  filecontent[0]; // 文件内容，长度为nlen
	} CBDContent_S;
	
	d. 对ds_start和ss_start,
	返回的结构为WSData_S后多了一个uint32_ws 的错误返回码。
	错误返回值参见：tagSSRetCode_E。
    enum tagSSRetCode_E
   {
	SS_RET_ERR_SUCCESS = 0,//没有错误
	SS_RET_ERR_NULLPARAM,  //传入的参数指针为空
	SS_RET_ERR_NOPARAM,    //没有指定输入参数
	SS_RET_ERR_NO_MATCHED_WINDOW, //没有找到对应的窗口
	SS_RET_ERR_CREATE_LIVEMGR,    //创建LiveMgr失败
	SS_RET_ERR_INIT_ENV,          //初始环境错
	SS_RET_ERR_INIT_CONTEXT,      //初始换上下文失败
	SS_RET_ERR_PARAM_REGION,      // 参数区域错误
	SS_RET_ERR_ADD_VIDEOSTREAM,   //添加video stream失败
	SS_RET_ERR_START_ENCODER,     //启动encoder失败
	SS_RET_ERR_START_OUTPUT,      //开始输出失败
	SS_RET_ERR_START_CAPTURE,     //启动捕获失败
	SS_RET_ERR_UNKNOWN            //未知错误
   };
    对应于ret_code小于SS_RET_ERR_SUCCESS和大于SS_RET_ERR_UNKNOWN的都是未知错误
	
	e. 
	WS_REC_FILE_GET_SUC时，	data 前256字节为请求的文件名，后data_len - 256字节为文件内容
	WS_RES_FILE_GET_FAIL,	WS_RES_FILE_SET_SUC, 	WS_RES_FILE_SET_FAIL时，data为请求的文件名

	f.对于返回的rtmp状态，WSData_S里data对应rtmp url.
	WS_RES_RTMP_CONNECTING,
	WS_RES_RTMP_CONNECT_SUC,
	WS_RES_RTMP_CONNECT_FAIL,
	WS_RES_RTMP_CONNECT_CLOSED,
