• How to setup HLS Live Video Streaming from iOS Device

  9 septembre 2017, par Sean

  Good day everyone !

  So, as the title suggests, i am developing an app with similar functionality to that off Periscope and Facebook Live video streaming. Here is what the end goal is :

  • A Broadcasting device [user]
  • EC2 Instance [Hosting an ffmpeg transcoder]
  • Cloudfront Distrubution [CDN]
  • 1 to n viewers of the live feed

  I’ve been doing a lot of googling and what I cant seem to figure out is :

  As you send chunks of video to the server from the Broadcaster, how do
  you create an
  .m3u8 playlist when you don’t have all the chunks of video yet (e.g. the
  device sends its first 5second chunk of video) ?

  It seems a .m3u8 file is created from a .mp4 file that is already complete, then broken down into chunks... But i’m sending chunks of the video to the server, how can it generate the .m3u8 file when more chunks are still coming from the Broadcaster, so the watchers / clients can continuously stitch together the video chunks ?

  I’ll be happy to clarify this question further. Thanks !

  I’m trying this guide to stream my Pi camera (running on raspberry pi 3b with raspbian) to YouTube live.
  when i try to install ffmpeg, I’m getting this message :

• How to streaming from laptop camera to server rtmp

  21 août 2017, par boygiandi

  I’m looking for a solution to send data from laptop camera using browser (Javascript) to a rtmp server (like facebook live or youtube). I did researched but no luck. What I got :

  1. Direct from camera to rtmp server ==> We can’t do this, browser WebRTC using udp and rtmp is tcp
  2. Another server as proxy ==> What I think is : browser using WebRTC and send video data to server. Server also running as a WebRTC client and receive video data, forward to ffmpeg process. ffmpeg send video data to rtmp server.

  The problem is I can’t find any working example for WebRTC on server (almost example use server to help 2 clients can connect together). What I need is use server as WebRTC client and get video data.
  I also take a look at RecordRTC but I only see example of upload video after stop record. I want to upload while recording (live stream)
  Please help
