Python and Youpaiyun interface docking tutorial: audio transcoding and merging

Introduction:
Youpaiyun is a cloud computing company that provides cloud storage and cloud processing services. They provide a wealth of The API interface facilitates developers to perform customized operations on cloud storage and cloud processing. This article will introduce how to use Python and Youpai Cloud interface to implement audio transcoding and merging functions.

1. Register a Youpaiyun account
If you don’t have a Youpaiyun account yet, please register one first and obtain the Access Key and Secret Key. These two keys will be used for API authentication. .

2. Install dependent libraries
To use Python and Youpaiyun interface, you need to install Youpaiyun’s Python SDK, which can be installed through the pip command:

pip install upyun

3. Create Python script
Create a Python script. The example script is named audio_convert_merge.py.

First, introduce the required modules into the script:

import upyun
import requests
import json

Then, configure the authentication information and other parameters of the API:

bucket_name = 'your-bucket-name'  # 又拍云空间名
operator_name = 'your-operator-name'  # 操作员名
operator_password = 'your-operator-password'  # 操作员密码

up = upyun.UpYun(bucket_name, operator_name, operator_password)

4. Implement audio transcoding
The following is a sample code for audio transcoding, taking the conversion of audio files in WAV format into MP3 format as an example:

def audio_convert(file_path):
    # 指定WAV格式的源文件和转码后的文件路径
    source_file = file_path
    target_file = 'convert/' + file_path[:-4] + '.mp3'

    # 设置转码任务的参数
    params = {
        'source': source_file,
        'targets': [
            {
                'save_as': target_file,
                'type': 'mp3',
            },
        ],
    }

    # 发起转码请求
    r = up.post('/tasks', json.dumps(params))

    # 输出请求结果
    print(r.status_code)
    print(r.text)

5. Implement audio merging
The following is a sample code for audio merging, which converts multiple audio files into MP3 format. Merge audio files in MP3 format into one file:

def audio_merge(file_list):
    # 设置合并任务的参数
    params = {
        'sources': file_list,
        'save_as': 'merge/merged.mp3',
    }

    # 发起合并请求
    r = up.post('/merge', json.dumps(params))

    # 输出请求结果
    print(r.status_code)
    print(r.text)

6. Call the function for audio transcoding and merging
At the end of the script, you can call the above function to implement the audio transcoding and merging functions:

if __name__ == "__main__":
    # 音频转码
    audio_convert('source.wav')

    # 音频合并
    audio_merge([
        'convert/1.mp3',
        'convert/2.mp3',
        'convert/3.mp3',
    ])

7. Run the script
Switch to the directory where the script is located on the command line, and run the following command to execute the script:

python audio_convert_merge.py

8. Summary
Through the above steps, we successfully Use Python and Youpai Cloud interface to implement audio transcoding and merging functions. By flexibly using Youpaiyun's API interface, we can easily implement more cloud storage and cloud processing related functions, which is of great significance to the optimization of cloud computing development and business applications. I hope this article will be helpful to you in the tutorial on how to use Python to interface with Youpai Cloud to implement audio transcoding and merging.
