Learn Python to implement Qiniu Cloud interface docking and audio and video merging

In an era of highly developed modern technology, audio and video merging has become an indispensable function in many application scenarios. Qiniu Cloud, as one of the leading cloud service providers in China, provides a series of powerful interfaces and tools to facilitate developers to implement functions such as audio and video processing and storage. This article will introduce how to use Python language to implement Qiniu Cloud interface docking and realize the audio and video merging function.

First, we need to install Qiniu Cloud SDK for Python, which can be installed through the pip command. Open a terminal or command prompt and enter the following command:

pip install qiniu

After the installation is complete, we can start writing code.

First, you need to import the qiniu package and other required Python modules. The specific code is as follows:

import qiniu
import requests

Next, we need to configure the Access Key and Secret Key of Qiniu Cloud, as well as the space name (Bucket) to be operated. The specific code is as follows:

access_key = 'your_access_key'
secret_key = 'your_secret_key'
bucket_name = 'your_bucket_name'

After configuring the relevant information of Qiniu Cloud, we can realize the audio and video merging function. First, we need to obtain the URL address of the audio and video files to be merged. Suppose we have two files, one is an audio file (audio.mp3) and the other is a video file (video.mp4).

audio_url = 'http://your_audio_url'
video_url = 'http://your_video_url'

Next, we need to use Qiniu Cloud’s interface to merge audio and video. The specific code is as follows:

# 设置Bucket的域名
qiniu.conf.BUCKET_HOST = '%s.qiniudn.com' % bucket_name

# 生成合并后的文件名和URL
merged_file_key = 'merged.mp4'
merged_file_url = 'http://%s/%s' % (qiniu.conf.BUCKET_HOST, merged_file_key)

# 调用七牛云的音视频合并接口
fops = 'avconcat/2/format/mp4|saveas/' + qiniu.urlsafe_base64_encode(bucket_name + ':' + merged_file_key)
saveas_key = 'avconcat/'
ret, info = qiniu.rs.fop(bucket_name, merged_file_key, fops)

In the above code, we merge audio and video through the avconcat operation, and then specify the format of the output file as MP4 through the format/mp4 operation . Finally, specify the location and file name to save the merged file through the saveas operation. After completing the audio and video merging, you can obtain the URL address of the merged file through Qiniu Cloud's API.

Finally, we can download the merged audio and video files locally by sending an HTTP request. The specific code is as follows:

# 下载合并后的文件
response = requests.get(merged_file_url)
with open('merged.mp4', 'wb') as f:
    f.write(response.content)

Through the above code, we can download the merged audio and video files to the local and save them as merged.mp4.

So far, we have completed the implementation of the Qiniu Cloud interface docking and audio and video merging functions. You can customize it according to your needs.

To summarize, this article introduces how to use Python to implement Qiniu Cloud interface docking and realize the audio and video merging function. By studying the content of this article, you can master the basic Qiniu Cloud API calling methods and implement audio and video processing functions. I hope this article can provide some help to the problems you encounter during development.
