• How to add a time limit for ffmpeg multiple outputting download ? [closed]

  8 juillet, par Nycelia

  I've been trying to get multiple outputs with different duration of segments from a playlist url using ffmpeg. Example : 120 seconds of a live stream. One output must download 8 times 15 seconds segments. Other output must download 4 times 30 seconds segments. Both outputs will have the same content, but with different durations. It works fine when I use a single output, but with 2 outputs, it's not limited to 120 seconds. Instead it just keeps downloading.

  


  Note : I know I could get a single output and divide it into segments later, but I need this approach.

  


  ffmpeg -t 120 -i <url> -c copy -f segment -segment_time 15 -reset_timestamps 1 -strftime 1 "15sec_%Y-%m-%d_%H-%M-%S.mp4" -c copy -f segment -segment_time 30 -reset_timestamps 1 -strftime 1 "30sec_%Y-%m-%d_%H-%M-%S.mp4"&#xA;</url>

  14 décembre 2024, par Furkan Gözükara

• 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) :
