These are notes while researching a way to convert a browser/website to a stream. This could be used for Facebook Live or for webrecording. TL'DR:

  • I started with Phantomjs - but that didn't support the html5 video tag
  • SlimerJS supports it, but there is no way to record audio directly (though this might come from desktop audio)
  • So I moved to research ffmpeg/X11/XVFB to record it with linux which works
  • But ffmpeg has no easy way to mix streams/overlays to I moved on to OBS with overlay browser support
  • I started researching options OBS in docker and it needed best a GPU , so I move to nvidia-docker
  • And so came across building game servers on EC2/AWS using GPUs and managed to run OBS inside of GPU g2x.large machine
  • I tried streaming to twich , which works great and managed to restream 4K 60FPS youtube on an AWS instance
  • Remote control works through OBS-Remote but OBS has kinda limit in types of features

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.
