• Auto launch the video player in Android from the browser like an iPhone does

  2 juin 2015, par Gcoop

  I have just created and iPhone web app, which has some x264 (mp4) video files on it. When I link directly to the file on the iPhone and the user taps the link, the video player is loaded and the video starts playing.

  Using the app on an Android phone causes the browser to download the video instead of just playing it. Is there a way to force a video player to just boot up and play the video not download it ?

  Thanks in advance.

• 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)

• 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)
# """

  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) :
