6.对讲
条件：摄像机连接成功
语法：
1）函数
-(int)start_talk; //开启对讲 -(int)start_talk_with_buffer_ms:(unsigned int) buffer_ms; //开启对讲，buffer_ms延迟时间 -(void)stop_talk; //关闭对讲，摄像机断开或离开视频页面，一定要停止对讲，否则下次录像会有异常
2）消息通知
FOUNDATION_EXPORT NSString* const IPCamera_Talk_Status_Changed_Notification;
3) 设置成功后的消息回调
-(void)IPCamera_response_function:(NSNotification*)note;
IPCamera.h宏定义了两种注册消息的方法
#define ADD_IPCAMERA_RESPONSE_WITHOUT_ARG(notice_name) \
[[NSNotificationCenter defaultCenter] addObserver: self selector: @selector(IPCamera_response_function:) name: notice_name object: nil]
#define ADD_IPCAMERA_RESPONSE_WITH_ARG(notice_name,camera_object) \
[[NSNotificationCenter defaultCenter] addObserver: self selector: @selector(IPCamera_response_function:) name: notice_name object: camera_object]
示列：
1）注册消息通知
ADD_IPCAMERA_RESPONSE_WITH_ARG( IPCamera_Talk_Status_Changed_Notification, cam_)
2）开启对讲
[cam_ start_talk］; 或： [cam_ start_talk_with_buffer_ms:50];
3）关闭对讲
[cam_ stop_talk];
4）对讲状态改变时的消息通知
-(void)IPCamera_response_function:(NSNotification*)note
{
if( [note.name isEqualToString:IPCamera_Talk_Status_Changed_Notification ])
{
NSLog(@"对讲状态改变");
if( STATUS_PLAYING == cam_.talk_status)
{
NSLog(@"对讲开启成功");
}
if( STATUS_STOPPED == cam_.talk_status)
{
NSLog(@"对讲关闭成功");
}
if( STATUS_REQUESTING == cam_.talk_status )
{
NSLog(@"请求开启对讲");
}
}
}
