• Download live stream with changing chunklist/.m3u8 using ffmpeg or something similar

  23 juillet 2023, par Oliwer

  I've been trying to record a live stream from a website that change the .m3u8 link from time to time, sometimes it changes every minute and sometimes it changes 3 times in 10 sec. Is there a way to download the live stream in another way ? From my basic knowledge I have understood that they are using cloudflare for the stream.

  


  I know that it's possible to download since other people have been able to do it, but I am not able to find any information about it online.

  


  I've tried to find if there is a "master" file which could be able to give me access to the entire stream without any success.
I have been using -i "chunklist.m3u8" -c copy file.mkv
But every time it changes i have to type it all over with the new chunklist.m3u8

  


  Edit : When the change comes, a Website.com/json/liveApi_hls.asp followed by live-website.hscdn.com/pop_cast29/abc0122_P-00001_20230723223118/index.m3u8 ?%24NjW80dXNopqYmpuYn5qcmJmYm5qcusnWz82imZiYtaK1uKKezbueaEM%3D%24

  


  The change between the files are everything after .m3u8 ?

  


• Live stream failed on Youtube

  20 septembre 2023, par kuldeep chopra

  We are currently running an AWS container that utilizes FFmpeg for live streaming while concurrently saving the stream as an MP4 file. However, we encountered an issue during a recent live stream session that was functioning correctly until approximately 13 minutes in, at which point FFmpeg reported the following error logs :

  


  ffmpeg [flv @ 0x555c4bdfe680] Failed to update header with correct duration.
2023-09-07T23:06:38.490+05:30 [flv @ 0x555c4bdfe680] Failed to update header with correct filesize.
2023-09-07T23:06:38.491+05:30 failed => rtmp://a.rtmp.youtube.com/live2/key......

  It's worth noting that we have conducted hundreds of live streams on YouTube without encountering this error before ; this is the first occurrence of such an issue.

  


  We would greatly appreciate it if you could investigate and provide insights into the underlying problem causing these error messages.

  


• FFMPEG - live stream with dynamic content

  6 octobre 2019, par Arturek

  I’m trying to create a live stream with changing data in real-time on youtube.

  Let’s say I want to show the current Bitcoin price in real-time. For instance, using python and sending requests to some public APIs, I can very easily get current prices of Bitcoin. But I have no idea how to create such a live stream, which will be automatically updated with fresh data.

  I know that I can use ffmpeg to stream on youtube, but how would I change the content of my stream ? I know how to create an image every n seconds with the current price, but then I don’t know how to update my live stream with this image.

  # To make sure you know what I mean, I created a basic sample.
  
  
  
  import requests
  
  import json
  
  import time
  
  
  
  createYtLiveStream()
  
  
  
  while(True):
  
    response = requests.get('https://api.coindesk.com/v1/bpi/currentprice.json').json()
  
    price = response['bpi']['USD']['rate']
  
  
  
    # Create an image with Bitcoin price inside
  
    img = convertTextToPng(price)
  
  
  
    # Update my live stream with this new image (I don't know how to do it)
  
    updateYtLiveStream(img)
  
  
  
    time.sleep(20)

  I want to do it on Ubuntu. Can you tell me how can I do it, please ?
  Thanks.
