Get an OpenCV video capture from an YouTube video URL
Why
- pafy is widely used to get the video URL from a YouTube video URL, but since it uses youtube-dl which has not been updated recently, it suffers from some issues (dislike_count not found...).
- This repository is a simplified version of what pafy does, by just getting the url of the video and creating an OpenCV video capture from it.
- It uses YT-DLP (https://github.com/yt-dlp/yt-dlp), which is a fork of youtube-dl that is updated frequently.
Requirement
- YT-DLP
- OpenCV
- NumPy
Installation
- The easiest way is to install it with pip:
pip install cap_from_youtube
- You can also install it from GitHub:
pip install git+https://github.com/ibaiGorordo/cap_from_youtube
Usage
cap_from_youtube()
cap_from_youtube()
is the main function to obtain a video capture from a YouTube video URL.- It requires the video URL as input and returns a
cv2.VideoCapture
object. - By default, it returns the video with the highest resolution available.
- You can specify the resolution you want to get with the
resolution
parameter.- Available resolutions: '144p', '240p', '360p', '480p', '720p', '720p60', '1080p', '1080p60', 'best'
- Example:
from datetime import timedelta
import cv2
from cap_from_youtube import cap_from_youtube
youtube_url = 'https://youtu.be/LXb3EKWsInQ'
start_time = timedelta(seconds=5)
cap = cap_from_youtube(youtube_url, 'best', start=start_time)
cv2.namedWindow('video', cv2.WINDOW_NORMAL)
while True:
ret, frame = cap.read()
if not ret:
break
cv2.imshow('video', frame)
if cv2.waitKey(1) & 0xFF == ord('q'):
break
list_video_streams()
- You can also use the
list_video_streams()
function to get the list of available video streams. - It requires the video URL as input and returns two values:
- streams: a list of VideoStream with the information of the available video streams.
- resolutions: a NumPy array with the available resolutions.
- Example:
from cap_from_youtube import list_video_streams
youtube_url = 'https://youtu.be/LXb3EKWsInQ'
streams, resolutions = list_video_streams(youtube_url)
for stream in streams:
print(stream)
