Python is a powerful programming language that is widely used in fields such as web crawling, data analysis, and artificial intelligence. In web crawling, it is often necessary to obtain videos from web pages or record web page videos. The following will introduce how to use Python to record webpage video.
import time
from selenium import webdriver
# Create driver
driver = webdriver.Chrome()
# Open web page
driver.get("https://www.baidu.com/")
# Wait for 5 seconds
time.sleep(5)
# Set Video resolution is 1366*768
driver.execute_script("document.body.style.zoom='80%'")
# Get video node
video = driver.find_element_by_tag_name("video")
# Start recording
video.play()
time. sleep(10)
video.pause()
# close the driver
driver.quit()
The above code uses Selenium module to simulate browser operation. First, we created a Chrome driver and opened the Baidu webpage. Then, we use the sleep function in the time module to wait 5 seconds to make sure the page is fully loaded.
Next, we use the execute_script method provided by WebDriver to shrink the page to fit the video resolution. To obtain a video node, use the find_element_by_tag_name method and set the tag name to "video". Finally, we start and stop recording video using the play and pause methods. After the recording is over, we close the driver and save the video file.
In practical applications, we can encapsulate the above code into a Python function, and control information such as the time, resolution, and save path of the recorded video through parameters. By using Python to record webpage videos, we can perform tasks such as automated testing, data collection, and webpage monitoring more flexibly.
