Python one-click download video script sharing

Requirements

I usually go to some professional video websites such as Tencent Video and Youku, and watch movies and TV series on them.One of the advantages of these sites is that they can cache videos, and you can enjoy watching dramas on the commute, such as the subway, because the Internet speed on the subway is usually not very good.

But there are some classic movies or TV series, and these videos are not provided, so we can only watch them on some small movie websites. The resources are there, but the problem is that most of these small movie websites do not have video download function., you can't watch it on the subway.

If you can download these videos and transfer them to your phone, can you watch them offline?

Next, the editor will demonstrate how to use python script to download the video of the small movie website with one click.

The following script can be learned

• Using python selenium
• Use of python requests
• Segment download video storage local
• Real-time output of video download progress

Note:

1. The script here is mainly used for testing and learning purposes, and should not be used for commercial purposes such as production environments

2. It is recommended that you visit the official designated platform or professional video website to support genuine versions

Solution

The editor takes the online home that I often watch as an example. This website can find a lot of American TV resources.

First, we use Google Chrome to open a video address, such as https://www.zxzj.fun/video/1529-1-1.html , press F12code> Or right-click "Inspect" to open the browser console

Then, click the Select Element button on the far left of the console, or press Ctrl + Shift + C , select the video area of ​​the web page, and you will see the video tag

It can be found that the src attribute value is the video link, and a separate .mp4 video address is used. In principle, this address can be downloaded directly from the browser.Copy this address and open it in the browser, you can right-click to download.But TV dramas usually have many episodes, and it is very cumbersome to manually open the webpage every time - open the console - copy the video address - open the video again - and finally download the video.This is when scripts come in handy, automating the process and simplifying the process of repetitive operations.

The overall idea of ​​the script

• Use selenium to open a webpage
• Use the selenium element selector to find the iframe where the video tag is located, switch to iframe
• Get the video address through the video tag, and then request the video content
• The video is spliced ​​and stored locally by downloading in segments

Summary

The above briefly shows the use of python's requests and selenium libraries to download a mp4 video, which can be used as a learning case.

There is still a lot of room for improvement

I have time to share more interesting and useful python scripts later.
