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

Issue 1: Too big H2 database

This is mostly due to H2 database getting too big. So it doesn't load in 5 seconds. You can debug this using

docker logs b4f559dc829b --tail 100

If it is too big you will need to defrag it.
