The method of downloading songs (or videos) from NCS (NoCopyrightSounds) and AudioLibrary was troublesome (unless it was Python), so I will write it as a memorandum.
Not for people who can find it by searching for "Pytube" It's an article for people who searched for "youtube video download Python" ...
The person who writes the article is also a beginner in programming, let alone Python: weary:
There are many ways to download Youtube videos for a long time, but roughly
Most people think that if they want to save Youtube videos, they often use a suspicious service on the web, but recently, the service itself is also "played by youtube": thinking ::
From youtube's point of view, it's natural because it's an access that doesn't generate advertising revenue. Of course there are long-lived services, but UIUX is low and full of ads.
For me, a beginner in Python (or programming itself), I thought it was the best because there were few libraries to remember and few methods. Intuition.
It's not a heavy library, so it works very lightly. I don't know how to handle it internally, but it's amazing.
I think that many people have used WEB services, but the biggest difficulty is their "slowness". Even a 20-minute video often has to wait 5 to 10 minutes. From the point of view of the service, it is natural because it is temporarily saved.
However, Pytube is explosive. Even if you download a 2-hour video in Full HD (about 1.5GB), it will end in a few minutes. (Of course, it depends on the line environment)
Since the internal operation of Pytube is a mystery, I will refrain from mentioning it Please be aware that ** YouTube prohibits scraping. Of course, operating YouTube by programming is not prohibited.
YouTube is officially provided with a "YouTube Data API", "Get the information on YouTube via here" is prepared. Of course, there is also an API-key, so it records who accessed it.
About YouTube Data API
Let me mention a little about the YouTube Data API. With this API, you can get video information and channel information, and perform various operations related to videos.
- Check the number of subscribers
- Check the number of video posts
- Check the number of views
- Check the video information (title/summary/URL)
- Find out about upcoming video posts
- Check the rating for the video
You can do various things. Although omitted, uploading operations are also possible, and if you want to make something like a YouTube browser, you can get essential information.
Pytube itself is not an official library, so it does not mean that "YouTube is OK". (Details are omitted) The copyright of the video data is owned by YouTube and the creator. Therefore, YouTube is "different for each video" as to what to do with the secondary use of downloadable videos.
*** Technically (easily) feasible, but should not be overused ***
I think that is the correct interpretation.
Copyright is very complicated, but if you are referring to this article, please refer to the following three.
In terms of YouTube terms of use, Please be aware that copyright law is also a ** very gray zone act **.
Jupiter Notebook people also need to install
pip install pytube
from pytube import YouTube
import os
import pandas as pd
import datetime
today = datetime.datetime.now()
todayis = str(today.year) + "Year" + format(today.month, '0>2') + "Moon" + format(today.day, '0>2') + "Day"
videopath = 'hogehoge' ###Specify the save destination of the video
savepath = videopath +'\\'+ todayis
if not os.path.exists(savepath):
os.mkdir(savepath)
def EasyVideoDL():
try:
videolist = '\\douga-list.csv'
video_df = pd.read_csv(videolist, header=None)
for url in video_df[0]:
yt = YouTube(url)
f = savepath + '\\' + yt.title
yt.streams.get_highest_resolution().download(f)
print(yt.title)
except:
pass
EasyVideoDL()
"Do you need a try?" Please forgive me for "meaning to make it a function": weary:
Explain each? To do
Here, prepare the save destination and read the CSV file containing the video URL to make it available. If you are interested, try running it line by line (block) in Jupiter Notebook.
today = datetime.datetime.now()
Get today's date as datetime type
todayis = str(today.year) + "Year" + format(today.month, '0>2') + "Moon" + format(today.day, '0>2') + "Day"
To the format of "YYYY year MM month DD day" with the fetched date as a character string You can format it when you get it with datetime type, but it's important to make it easy to understand: weary:
videopath = 'hogehoge'
savepath = videopath +'\\'+ todayis
Specify the (parent) directory where you want to save the video (Windows people are happier to use "r") Define the directory name for each date actually saved
if not os.path.exists(savepath):
os.mkdir(savepath)
Create a date directory. If you already have it, do nothing.
videolist = '\\douga-list.csv'
video_df = pd.read_csv(videolist, header=None)
Store CSV in pandas DataFrame. Delete the header when storing (not needed this time)
The contents of CSV look like this
https://www.youtube.com/watch?v=Kp-eibuQpWg https://www.youtube.com/watch?v=JgT5vhDB7W8 https://www.youtube.com/watch?v=kY-6R5fa0gwThere is no intention in the URL destination. I just refer to a long video (see below)
for url in video_df[0]:
yt = YouTube(url)
f = savepath + '\\' + yt.title
yt.streams.get_highest_resolution().download(f)
print(yt.title)
video_df. Since it is only the first column, specify video_df [0]. Store the retrieved value in url.url to the YouTube method of Pytube and store it.f..title gets the title of the video)Windows or Mac? Since "/" and "." Cannot be used for folders, I love that area.
yt.streams.get_highest_resolution().download(f)
yt is a translation ofYouTube (url),
You can get the video data by continuing with .streams from there.
This time I used .get_highest_resolution ().
This refers to "the best quality video with audio".
However, this is the songwriter, and the composition of the Youtube video is as follows. (Actually it depends on the video being uploaded)
| file | Video | voice | format |
|---|---|---|---|
| 1 | 720p | AAC | MP4 |
| 2 | 1080p | None | MP4 |
| 3 | 360p | AAC | MP4 |
| 4 | 360p | AAC | webm |
| 5 | None | AAC | MP4 |
| 6 | None | AAC | webm |
According to the current specifications of Youtube, it seems that 1080p or higher resolution videos are "separated from audio" operation, and 1080p videos cannot be directly downloaded as MP4 with audio. If you want to download high quality 1080p or higher videos, It is necessary to download the video without audio and the video with audio only once, synthesize them, and regenerate them. (This may also be the reason why the suspicious service on the WEB is struggling.)
So, you can get the movie of 720p + AAC with.get_highest_resolution ().
You can also specify this combination using something called itag,
I couldn't grasp the regularity of itag, so I used the one that gives the same result in a stable manner.
(If you want to collect only songs, use .get_audio_only () to target AAC-MP4)
And
Save the video with .download (). Specify the save destination folder in the argument.
In this case, it's f.
If you turn this to the end of video_df with a for statement, the videos will be saved in order.
The last print may or may not be present.
Since you can see which video the DL has finished, it is just displayed.
As you can see when you run it, it's faster than watching a video on youtube. I think VideoBrowser will do its best only a few seconds before the playhead, so ** You can see that it puts a load on youtube rather than the act of viewing it with an application or browser. ** **
I don't think Google will get angry at this level, I don't want to be glared at by Google, so I will use it moderately.
If you've ever stared at Google Chrome developer tools, you know. Youtube videos are sometimes divided into multiple parts in terms of data. I don't know if it's the length or capacity of the video ...: thinking:
Considering that, pytube that exports as one file is excellent.
I'm a member of Youtube Premium, so I don't need to say "to see it on a mobile app". It was around this time that I wish I could download and watch it on my PC.
It was a good subject to think about during the New Year holidays: relieved:
