5.音频
条件：摄像机连接成功
语法：
1)函数
-(int)playAudio; //开启音频 -(void)stopAudio; //关闭音频
2）消息通知
FOUNDATION_EXPORT NSString* const IPCamera_Audio_Status_Changed_Notification;
3）设置后的消息回调
-(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_Audio_Status_Changed_Notification, cam_)
2）开启音频
[cam_ playAudio];
3）关闭关闭
[cam_ stopAudio];
4）音频状态改变时的消息通知
-(void)IPCamera_response_function:(NSNotification*)note
{
if( [note.name isEqualToString:IPCamera_Audio_Status_Changed_Notification ])
{
NSLog(@"音频状态改变");
if( STATUS_PLAYING == cam_.audio_status )
{
NSLog(@"音频开启成功");
}
if( STATUS_STOPPED == cam_.audio_status )
{
NSLog(@"音频关闭成功");
}
if( STATUS_REQUESTING == cam_.audio_status )
{
NSLog(@"请求开启音频");
}
}
}
