Is there any way to download a video on youtube using urllib in Python?

I tested, but it does not work (just an example):

import urllib.request


youtube = ""

pagina = urllib.request.urlopen(youtube)

urllib.request.urlretrieve("", "video.mp4")

python python-3.x

Note: Remember that Youtube has terms and conditions, if the videos are not yours I do not recommend doing this, like Wallace said

There is a dependency-free lib called pytube , install using PIP, type in terminal or cmd:

pip install pytube

Script example:

from pytube import YouTube

# Esta parte não é necessária é apenas usada para entender o exemplo
from pprint import pprint

yt = YouTube("http://www.youtube.com/watch?v=Ik-RsDGPI5Y")

# Uma vez selecionado você pode ver todos formatos e resoluções disponíveis do video que deseja acessar

print(yt.get_videos())

# Exemplos de saídas possíveis

# [<Video: MPEG-4 Visual (.3gp) - 144p>,
#  <Video: MPEG-4 Visual (.3gp) - 240p>,
#  <Video: Sorenson H.263 (.flv) - 240p>,
#  <Video: H.264 (.flv) - 360p>,
#  <Video: H.264 (.flv) - 480p>,
#  <Video: H.264 (.mp4) - 360p>,
#  <Video: H.264 (.mp4) - 720p>,
#  <Video: VP8 (.webm) - 360p>,
#  <Video: VP8 (.webm) - 480p>]

# O nome do video é automaticamente gerado a partir do titulo, mas você pode sobreescrever

# view the auto generated filename:
print(yt.filename)

# Pulp Fiction - Dancing Scene [HD]

# Renomeia:
yt.set_filename('Dancing Scene from Pulp Fiction')

# Você pode ficar a lista por tipo
print(yt.filter('flv'))

# [<Video: Sorenson H.263 (.flv) - 240p>,
#  <Video: H.264 (.flv) - 360p>,
#  <Video: H.264 (.flv) - 480p>]

# Note que a lista é ordenada da menor resolução para maior
# Se esta procurando a maior resolução pelo formato faça isso:

print(yt.filter('mp4')[-1])

#Saída:
# <Video: H.264 (.mp4) - 720p>

# Você pode ver todos formatos por resolução
print(yt.filter(resolution='480p'))

# [<Video: H.264 (.flv) - 480p>,
#  <Video: VP8 (.webm) - 480p>]

# E pode pegar um video por resolução e formato

video = yt.get('mp4', '720p')

# NOTE: get() só irá reconhecer os formatos e resoluções disponiveis

print(yt.videos)

#[<Video: MPEG-4 Visual (.3gp) - 144p>,
# <Video: MPEG-4 Visual (.3gp) - 240p>,
# <Video: Sorenson H.263 (.flv) - 240p>,
# <Video: H.264 (.flv) - 360p>,
# <Video: H.264 (.flv) - 480p>,
# <Video: H.264 (.mp4) - 360p>,
# <Video: H.264 (.mp4) - 720p>,
# <Video: VP8 (.webm) - 360p>,
# <Video: VP8 (.webm) - 480p>]

# Since we have two H.264 (.mp4) available to us... now if we try to call get()
# on mp4...

video = yt.get('mp4')
# MultipleObjectsReturned: 2 videos met criteria.

# In this case, we'll need to specify both the codec (mp4) and resolution
# (either 360p or 720p).

# Okay, let's download it! (a destination directory is required)
video.download('/tmp/')

By command line:

Specifies the resolution:

$ pytube -r 720p http://www.youtube.com/watch?v=Ik-RsDGPI5Y

Specify where you want to save:

$ pytube -e mp4 -p ~/Downloads/ http://www.youtube.com/watch?v=Ik-RsDGPI5Y

Specifies name to be saved:

$ pytube -e mp4 -f Dancing Scene from Pulp Fiction http://www.youtube.com/watch?v=Ik-RsDGPI5Y

Specifies the resolution and desired format:

$ pytube -e mp4 -r 720p http://www.youtube.com/watch?v=Ik-RsDGPI5Y

It seems that according to the Term of Use , it is not legal to download Youtube videos.

There will probably be no APIs (at least politically correct) to support this.

In this SOEN answer , it also talks about it.
