• Python code to download hls stream to mp4

  2 décembre 2024, par Maad A.Galil

  I wrote the following code to download a video from a website. Chrome extensions can detect the video and download it. However, my code gets the following errors. Any help ?

  


  from bs4 import BeautifulSoup
import requests
from subprocess import check_output

video_url = 'https://www.dimakids.com/ab6al-aldigetal-s3-1415387355-21011.html#sets'
headers = {'User-Agent': 'Mozilla/5.0'}

url = requests.get(video_url, headers=headers)
page = url.content
soup = BeautifulSoup(page, "html.parser")

result = str(soup.find_all('video')[0])
result = result.split('src="')[1].split('" type=')[0] 
print(result)

# seg = requests.get(result)
# """
# Error: requests.exceptions.SSLError: HTTPSConnectionPool(host='stream.foupix.com', port=443): Max retries exceeded with url: /animeios/1415387355/ab6al_aldigetal_s3_01.mp4/index.m3u8?tkn=jja4Czj-AzbJx1JmvDvQeA&tms=1733079050 (Caused by SSLError(SSLCertVerificationError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1108)')))

# print(seg)


print(check_output(f'ffmpeg -i "{result}" -codec copy file.mp4', shell=True))
"""

  The link works as any hls downloader can capture the video and download it as seen here (of course token and timestamp values change everytime it captures the video) :

• avformat/matroskaenc : Allow to use custom reformatting functions

  avformat/matroskaenc : Allow to use custom reformatting functions
  Matroska uses variable-length elements and in order not to waste
  
  bytes on length fields, the length of the data to write needs to
  
  be known before writing the length field. Annex B H.264/5 and
  
  WavPack need to be reformatted to know this length and this
  
  currently involves writing the data into temporary buffers ;
  
  AV1 sometimes suffers from this as well.
  This commit aims to solve this by adding a callback that is called
  
  twice per packet : Once to get the size and once to actually write
  
  the data. In case of WavPack and AV1 (where parsing is cheap due
  
  to length fields) both calls will just parse the data with only
  
  the second function writing anything. For H.264/5, the position
  
  of the NALUs will need to be stored to be written lateron.

• How to calculate the "Range" header for mp4 file to play/download a part of it ? [youtube-dl]

  5 décembre 2016, par supersan

  I’m using youtube-dl to download videos from YouTube. Unfortunately, sometimes I just need to download a part of the video like 10 seconds of a 3 hour video and here is how I see I can do it.

  Step 1 : Get the URL of the mp4 file from youtube-dl.

  youtube-dl -g -f "[ext=mp4]" https://www.youtube.com/watch?v=qOZ1u9VpoMk

  This returns $url : the full URL of mp4 file on server.

  Step 2 : Download part of the video using curl

  curl -r $startBytes-$endBytes $url

  But how to calculate $startBytes and $endBytes. What is the formula for that ?

  P.S I was thinking could be something as simple but this isn’t it..

  $startBytes = (total_size_of_video / total_length_of_video_secs) * start_seconds

  P.P.S. When I play the mp4 video in Chrome and use the scrub bar to jump around in the video, Chrome too send the Range header to the same URL (as I can see in fiddler)
