• Youtube 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 ?

  # 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']
  
  
  
    updateYtLiveStream(price)
  
  
  
    time.sleep(20)

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

• Streaming 4K video file to YouTube on a Raspberry Pi 4 using FFMPEG

  25 mai 2021, par martijn

  I'm trying to stream a 4K video file to YouTube on a raspberry pi4 using FFMPEG (version : Linux raspberrypi 5.10.17-v7l+ #1414 SMP Fri Apr 30 13:20:47 BST 2021 armv7l GNU/Linux, 8gb).
I know you cannot do that with older Pi-versions.
I didn't find the proper ffmpeg commands yet, so I cannot test it right now. But before I give it a try, is it basically possible to stream 4K in this way with this version of the Pi ?

  


• Multiple download trim videos ffmpeg + youtube-dl [duplicate]

  4 décembre 2020, par sl4g

  I'm tryng to make a bash script to download and trim videos from URLs in a .txt file, using ffmpeg and youtube-dl. From the Internet I found this https://askubuntu.com/questions/970629/how-to-download-a-portion-of-a-video-with-youtube-dl-or-something-else and this How can I batch/sequentially download m3u8 files using ffmpeg ? and based on that I made this :

  


  #!/bin/bash

#only download the half of urls

HoldList="/home/user/desktop/dir1/code/bash/web.txt"

index=0
while read line ; do
    ffmpeg -ss 00:50:30 -to 00:51:00 -i "$(youtube-dl -f best --get-url $line)" -c:v copy -c:a copy output-${index}.mp4
    ((index=index+1))
done < "$HoldList"


  


  This code only downloads half of the videos. Download one, ignore the next, then repeat...

  


  How can I make not skip every other URL from the file ?

  


  I'm a newbie in Bash script (and in this site), and English is not my first language.
