Go

Go SDK installation and usage

The Go SDK currently only supports Linux and macOS

The SDK only offers to identify the content of a specified section of the file, identifying all the content of the entire file requires traversing the entire file

Adding dynamic libraries

1. Add the path where the dynamic library is located to the environment variable (temporary)

# Add environment variables 
# Replace acrcloud_dlib_path with libacrcloud_extr_tool.so
$ LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/acrcloud_dlib_path/
$ export LD_LIBRARY_PATH

2. Place the dynamic library in the same directory as your generated go binary program (temporary)

The most convenient way

3. Adding dynamic libraries to the system (permanently)

The following commands all require root privileges to run

# donwload the lib
$ sudo curl -fsSL https://raw.githubusercontent.com/acrcloud/acrcloud_sdk_golang/master/linux/x86-64/acrcloud/libacrcloud_extr_tool.so -o /usr/local/lib/libacrcloud_extr_tool.so
# Creating dynamic library configuration files
$ sudo bash -c "echo /usr/local/lib > /etc/ld.so.conf.d/acrcloud.conf"
# Update system configuration
$ sudo ldconfig

Use go get to get the SDK

$ go get github.com/acrcloud/acrcloud_sdk_golang/acrcloud

Initialization

First go to ACRCloud Developer Platform Console > Audio & Video Recognition to get Access Key, Access Secret and Host.

The obtained configuration information is then imported into ACRCloudRecognizer and initialized.

package main

import "github.com/acrcloud/acrcloud_sdk_golang/acrcloud"

func main() {

	host := "Host"
	accessKey := "Access Key"
	accessSecret := "Access Secret"

	configs := map[string]string{
		"access_key":     accessKey,
		"access_secret":  accessSecret,
		"host":           host,
		"recognize_type": acrcloud.ACR_OPT_REC_AUDIO,
	}
	
	var recHandler = acrcloud.NewRecognizer(configs)
	
}

Method

RecognizeByFile(filePath string, startSeconds int, lenSeconds int, userParams map[string]string)

Identify the specified location of multimedia files

params	description
filePath	string，Multimedia file path
startSeconds	int，Recognition start position (unit: second)
lenSeconds	int，Identification length (in seconds, default is 10, maximum is 12)
userParams	map[string]string，Search parameters (only humming search is useful)

Sample code:

package main

import (
	"fmt"
	"github.com/acrcloud/acrcloud_sdk_golang/acrcloud"
)

func main() {
	filename := "test.mp4"

	configs := map[string]string{
		"access_key":     accessKey,
		"access_secret":  accessSecret,
		"host":           host,
		"recognize_type": acrcloud.ACR_OPT_REC_AUDIO,
	}

	recHandler := acrcloud.NewRecognizer(configs)

	userParams := map[string]string{}

	result := recHandler.RecognizeByFile(filename, 0, 10, userParams)
	fmt.Println(result)
}

RecognizeByFileBuffer(data []byte, startSeconds int, lenSeconds int, userParams map[string]string)

Identify the specified location of the read multimedia file

params	description
data	[]byte，Buffer of the multimedia file to be read
startSeconds	int，Recognition start position (unit: second)
lenSeconds	int，Identification length (in seconds, default is 10, maximum is 12)
userParams	map[string]string，Search parameters (only humming search is useful)

Sample code:

package main

import (
	"fmt"
	"github.com/acrcloud/acrcloud_sdk_golang/acrcloud"
	"io/ioutil"

	userParams := map[string]string{}

	result := recHandler.RecognizeByFileBuffer(buffer, 0, 10, userParams)
	fmt.Println(result)

}

package main

import (
	"fmt"
