• How do I compile a c++ repository with multiple libraries [on hold]

  12 septembre 2017, par Firat Oezcan

  before someone comes and tells me that I should just google stuff first. I did. I didn’t really found anything that suits my needs and also asked my colleagues and other graduates and no one really could help me out.

  It is about this repository specifically : https://github.com/facebook/transform360

  Yes, there are literal instructions on how to do it but they are, honestly, too vague for me. I know that sounds really weird but I guess I’m just spoiled by Unity3D and other IDEs that did most of it for me.

  I don’t understand what is meant with :
  Build .cpp and .h files in Transform360, together with openCV, as a library, where these files are dependent on openCV
  and this line
  Add the Transform360 library file to the extra-libs of ffmpeg.

  I would love if anyone could help me out or better, explain to me how something of this kind is done correctly so I don’t have to ask again. Or really, just point me to information that already exists.
  Thanks in advance

• Instagram Live API using Graph API

  16 août 2020, par Deepak Sharma

  I see Facebook has new graph API for live video. But I am not sure if it can used to go live on Instagram as well. I see third party softwares such as Yellow Duck being able to go live on Instagram. Not only that, a lot of softwares support streaming to any destination by just using an RTMP link. So does that mean any service that can generate an RTMP stream can broadcast to Instagram (with/without login to Instagram) ? How does Instagram live work if one can generate an RTMP stream ? Finally, if I can generate an RTMP/RTMPS stream locally on my desktop or phone using ffmpeg libraries, can I stream to Instagram ?

  


• 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 !
