• RTSP to RTMP Youtube Live only displays online for few seconds

  2 juin 2016, par Poison

  I’m trying to get the feed from an IP camera to Youtube Live. Simple enough uh.

  The command I’m using is the usual :

  ffmpeg -i rtsp://user:pass@ip:port/videoMain -f flv -r -s -an rtmp://a.rtmp.youtube.com/live2/per-sonal-code

  What happens

  Live Youtube receives the signal and says its healthy, after two or less seconds a red box appears saying they’re not receiving my signal. After that it displays "No signal". Webcam image is never shown.

  What I’ve tried

  Different parameters (-re, -rtsp_transport tcp, -s 640x480, -g 30, -r 30 ..) and different combinations of them, plus different resolutions, different buffer sizes and stream sizes, and different Ingestion settings on Youtube.

  Followed different very basic stuff tutorials.

  I’ve done it with ffmpeg in Windows 7 and Ubuntu 16.04, different networks (home and work), checked for possible port problems,...

  What confuses me

  Using streaming software like XSplit, or Manycam it actually works on the same computers !
  Also using the different command combinations, Youtube always receives the signal and its healthy before changing and displaying "No signal", its not complaining about low bitrate, or wrong format like I’ve seen in the different tutorials.

  I need to create two different streams for two cams, so ideally I’d prefer to use ffmpeg. However if anyone knows a software that can do this, please tell me. I’ve been stuck with this long enough !

  Thanks.

• Youtube-DL file download live progress

  7 février 2015, par roshkattu

  I am using the YoutubeDL library in a project. My environment is based on WINDOWS with XAMPP as the webserver boundle (apache,php,mysql,etc). I am using the youtube-dl.exe file to download the video and then use ffmpeg.exe to convert the video to an MP3 audio file.

  At the moment, I have an issue related to programming : I want to show live a progressbar while the video is downloaded with the youtube-dl.exe file. This exe creates a log file, that is updated while the video is downloaded. So my approach on this was to create a PHP file, that opens, parses the log file and get’s the progress percent, and sends it as a json encoded value to an AJAX function that is called every 100MS. Indeed, if the video is too large, there will be a very high ammount of data while polling the PHP file to get the progress state. And sometimes, the browser either crashes or freezes because of this ajax polling.

  My question is : is there any better approach to do this with PHP/AJAX ? Rathar than poll the file every 100MS, or 50MS ?

• 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.
