以下是一个简单的使用海康SDK实现语音对讲功能的golang代码示例:
```go
package main
import (
"fmt"
"os"
"time"
"unsafe"
"github.com/hongrichang/poc/hikvision"
)
func main() {
// 初始化SDK
err := hikvision.Init()
if err != nil {
fmt.Println("SDK初始化失败:", err)
return
}
defer hikvision.Cleanup()
// 登录设备
deviceIP := "192.168.1.64"
username := "admin"
password := "admin123"
loginID, err := hikvision.Login(deviceIP, username, password)
if err != nil {
fmt.Println("登录设备失败:", err)
return
}
defer hikvision.Logout(loginID)
// 开启语音对讲
voiceComHandle, err := hikvision.StartVoiceCom(loginID)
if err != nil {
fmt.Println("开启语音对讲失败:", err)
return
}
defer hikvision.StopVoiceCom(voiceComHandle)
// 发送语音数据
filepath := "/path/to/audio/file.pcm"
file, err := os.Open(filepath)
if err != nil {
fmt.Println("打开音频文件失败:", err)
return
}
defer file.Close()
buffer := make([]byte, hikvision.VoiceDataLength)
for {
n, err := file.Read(buffer)
if err != nil {
fmt.Println("读取音频数据失败:", err)
return
}
if n == 0 {
break
}
voiceData := hikvision.VoiceData{
Length: hikvision.VoiceDataLength,
AudioFlag: 0,
AudioFormat: 1,
SampleRate: 8000,
SampleBits: 16,
Channel: 1,
Data: (*byte)(unsafe.Pointer(&buffer[0])),
}
err = hikvision.SendVoiceData(voiceComHandle, voiceData)
if err != nil {
fmt.Println("发送语音数据失败:", err)
return
}
time.Sleep(time.Millisecond * 20)
}
fmt.Println("语音数据发送完毕")
}
```
需要注意的是,以上示例代码仅供参考,实际使用时需要根据具体的需求进行调整。
