在C#中處理ONVIF音頻數(shù)據(jù),您可以使用ONVIF的Media服務(wù)來獲取音頻流數(shù)據(jù)。首先,您需要使用ONVIF的設(shè)備管理服務(wù)來發(fā)現(xiàn)并連接到網(wǎng)絡(luò)攝像機(jī)。然后,使用Media服務(wù)來獲取音頻流數(shù)據(jù)。以下是一個(gè)簡單的示例代碼,演示如何處理ONVIF音頻數(shù)據(jù):
using System;
using System.ServiceModel;
using System.ServiceModel.Channels;
using System.ServiceModel.Description;
using System.Xml;
using System.Net;
class Program
{
static void Main(string[] args)
{
// 通過ONVIF設(shè)備管理服務(wù)查找設(shè)備
var discoveryClient = new DiscoveryClient(new UdpDiscoveryEndpoint());
var findCriteria = new FindCriteria(typeof(DevmgmtDevice));
var findResult = discoveryClient.Find(findCriteria);
// 連接到設(shè)備
var deviceAddress = findResult.Endpoints[0].Address;
var deviceServiceAddress = new Uri($"http://{deviceAddress}/onvif/device_service");
var deviceServiceClient = new DeviceServiceClient("DeviceBinding", new EndpointAddress(deviceServiceAddress));
var deviceInfo = deviceServiceClient.GetDeviceInformation();
// 獲取Media服務(wù)地址
var mediaServiceAddress = deviceServiceClient.GetServices(true).FirstOrDefault(s => s.Namespace == "http://www.onvif.org/ver10/media/wsdl")?.XAddr;
var mediaServiceClient = new MediaClient("Media", new EndpointAddress(mediaServiceAddress));
// 獲取音頻流URI
var profileToken = mediaServiceClient.GetProfiles().FirstOrDefault()?.token;
var streamUri = mediaServiceClient.GetStreamUri(profileToken, StreamSetup.CreateRtspStream("RTP-Unicast", null));
// 處理音頻數(shù)據(jù)
var rtspClient = new RtspClient(streamUri.Uri);
rtspClient.DataReceived += (sender, e) =>
{
byte[] audioData = e.Data;
// 處理音頻數(shù)據(jù)
};
rtspClient.Start();
Console.ReadLine();
rtspClient.Stop();
}
}
在上面的示例中,我們首先通過ONVIF設(shè)備管理服務(wù)發(fā)現(xiàn)設(shè)備并連接到設(shè)備。然后獲取Media服務(wù)地址并獲取音頻流URI。最后,我們使用一個(gè)RtspClient來接收音頻數(shù)據(jù)并進(jìn)行處理。您可以根據(jù)您的實(shí)際需求自定義處理音頻數(shù)據(jù)的邏輯。
