Question

当我将电影上传到youtube然后从给定的链接下载时，它是同一部电影，但文件咬合被改变了...... 有没有办法撤消youtube编码所以我上传的文件和我下载的文件将是100％相同??

我正在使用python pytube下载

由于

from pytube import YouTube
import defines
# not necessary, just for demo purposes.
from pprint import pprint

yt = YouTube(defines.url)

# Once set, you can see all the codec and quality options YouTube has made
# available for the perticular video by printing videos.

pprint(yt.get_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>]

# The filename is automatically generated based on the video title.  You
# can override this by manually setting the filename.

# view the auto generated filename:
print(yt.filename)
# Pulp Fiction - Dancing Scene [HD]

# set the filename:
# yt.set_filename('Dancing Scene from Pulp Fiction')

# You can also filter the criteria by filetype.
pprint(yt.filter('flv'))


print(yt.filter('mp4')[-1])
# <Video: H.264 (.mp4) - 720p>

# You can also get all videos for a given resolution
pprint(yt.filter(resolution='480p'))

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



video = yt.get('3gp', '240p')

# NOTE: get() can only be used if and only if one object matches your         criteria.
# for example:

pprint(yt.videos)  

video = yt.get('webm')
video.download('here1.webm')

Answer 1

Youtube正在对视频进行编码以节省带宽并最大限度地减少不必要的网络流量。这些文件在youtube服务器上进行编码，原始文件很可能在此过程中被删除。

你为什么要这样做呢？您可以通过各种其他服务或协议（如ftp或Dropbox等）传输/共享文件（如果这就是你所追求的）。
