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

Compilation FFMpeg / NVENC + NVRESIZE + QSV + VAAPI + VDPAU + OpenCL

nVidia nvresize patch is outdated and not more compatible to the latest version of FFmpeg, so it's not included in this documentation.

(even if I've passed a lot of time at trying to make it compile... without any success)

Please don't rely on this page: https://developer.nvidia.com/ffmpeg, the implementation is a hack and was never been added to the main FFmpeg tree.

The following files show an example of how to create subdomains for onion site hidden services. (This hasn't been tested for hidden services for anything other than HTTP/HTTPS.)

(You might also want to read our blog post about ProPublica’s Tor hidden service, including a tutorial and notes on running a hidden service: https://www.propublica.org/nerds/item/a-more-secure-and-anonymous-propublica-using-tor-hidden-services )

In general, this works (maybe just in recent Tor clients) because Tor will handle the connection to www.xxxxxxxxxxxxxxxx.onion as a connection to xxxxxxxxxxxxxxxx.onion. The encapsulated HTTP/HTTPS connection contains the subdomain in the Host: header (and in the case of HTTPS, the SNI

See my DASH-IF presentation from October, 2014:

1. encode multiple bitrates with keyframe alignment:
   ffmpeg -i ~/Movies/5D2_Portrait.MOV -s 1280x720 -c:v libx264 -b:v 1450k -bf 2 \
     -g 90 -sc_threshold 0 -c:a aac -strict experimental -b:a 96k -ar 32000 out.mp4

   My input was 30 fps = 3000 ms. If it were 29.97, then a GOP size of 90 frames will yield a base segment
   size of 3003 milliseconds. You can make the segment size some multiple of this, e.g.: 6006, 9009, 12012.

Quick and easy way of making Chrome send bittorrent magnet links to a remote Transmission instance using its API on Ubuntu with xdg. This method does not require modifying any system files or xdg's scripts, whereas most of the examples I found on the Internet did require such hacks.

Chrome does not handle default applications, instead relying on the OS to manage that. The default handler in Ubuntu is xdg, which maps the MIME type to the default application. Extra tooling is required because xdg requires a registered desktop file, so you can't simply give it a command to run.

Steps:

1. Install the shell script transmission-remote-magnet ideally in /usr/local/bin: ln -s ~/src/transmission-remote-magnet.bash transmission-remote-magnet

2. Install the desktop file, which is required for xdg to work and will likely require sudo: desktop-file-install ./transmission-remote-magnet.desktop
