• Live stream videos on YouTube with ffmpeg ?

  30 janvier 2021, par Manuservus

  What the program should do :

  


  It should download a video from an URL.

  


  Then put the video into a streaming interface (on the right side there should be the live chat from YouTube, in the middle, there should be the downloaded video).

  


  Next stream it live to YouTube.

  


  The process should repeat endless times.

  


  Download video from URL —> Stream it live to YouTube in a streaming interface -> repeat the whole process.

  


  Is this even possible in Python ? If yes how ?

  


  I would appreciate any help !

  


  PS : The stream should run smoothly without a break. That means : As soon as a video is finished, the next comes straight away.

  


• How to setup live video stream from webcam to the server, and then beyond ? [closed]

  15 mai 2020, par Parth Sarthi

  I have an application, that is written in Node and Nuxt, to host online exams. My clients are now demanding youtube like livestream for their students. I can't use WebRTC because there will be thousands of students watching the live video, so I don't think teacher's bandwidth will be able to deliver that.

  



  Now I want to know what other options do I have ? How do I send video stream from teacher's laptop to the server in real time ? I am assuming getUserMedia ? Then how do I convert the live stream incoming from the teacher into something like HLS ? I am assuming ffmpeg ? but what commands will do that actually ? cause i can't seem to find any which will take in Media Stream and convert it into HLS. And lastly how do I server it back to the students.

  



  I have already setup the live chat for every classroom with socket.io so I am stuck here.

  


• How to process video stream ?

  27 avril 2016, par sharpener

  I would like to ask some experienced multimedia professional how to proceed with following task :

  Given URL provides video stream and we would like to get access to decoded frames (byte stream in memory) in managed Win7+ application (C#). We don’t want to render/present the frames the standard way. The video format is known but not fixed (might get changed between two successive sessions, but we will know the parameters).

  So far, I have found there are several methods and I have build following picture in my mind :

  1. ffmpeg wrapper
     • Pros
       1. Self contained (no dependency to windows technologies)
       2. Powerful
     • Cons
       1. Little more complex to understand
       2. Lot of different wrapping variants (FFmpeg.NET, ffmpeg-sharp, ffmpeg-shard, FFmpeg.AutoGen, ...)
  2. DirectShow wrapper
     • Pros
       1. Widely used/supported technology (variaous filters freely available)
       2. Nice/detailed documentation on MSDN
     • Cons
       1. Quite old
       2. Considered obsolete from the point of author’s view (available only for desktop model on runtime >= Win8)
  3. MediaFoundation wrapper
     • Pros
       1. Theoretical successor of DirectShow, so should be available in the future
     • Cons
       1. Seems to be not as good as DirectShow
       2. Not very popular, limited "community" support
  4. FFmpegInterop wrapper
     • Pros
       1. Microsoft’s open source wrapper alternative
     • Cons
       1. Not available for runtime < Win8
