FFMPEG - map of formats to default mime types
// INCOMPLETE
// This command will give you list of available FFMPEG formats and their default Mime types
// ffmpeg -formats -hide_banner | tail -n +5 | cut -c5- | cut -d' ' -f1 | xargs -i{} ffmpeg -hide_banner -h demuxer={} | pcregrep -o2 -o4 -M '(Muxer (\w+) )|(Mime type:( .*).)'
// And then parse the output with regex to JSON format in JavaScript for example:
// str.match(/(.*)\n (.*)/gm).map(m => `"${m.replace(/\n /, '": "')}"`).join(',\n');
// Combine the output with MDN - Common MIME types
// https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/MIME_types/Common_types
// And with IANA:

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
