If you want to stream a slideshow using ffmpeg, it seems like one easy way to do it is to create an imagepipe of the files.
This can then be streamed to twitch.tv or youtube ... https://trac.ffmpeg.org/wiki/StreamingGuide

Learning Rust
The following is a list of resources for learning Rust as well as tips and tricks for learning the language faster.
Warning
Rust is not C or C++ so the way your accustomed to do things in those languages might not work in Rust. The best way to learn Rust is to embrace its best practices and see where that takes you.
The generally recommended path is to start by reading the books, and doing small coding exercises until the rules around borrow checking become intuitive. Once this happens, then you can expand to more real world projects. If you find yourself struggling hard with the borrow checker, seek help. It very well could be that you're trying to solve your problem in a way that goes against how Rust wants you to work.

| This script will print package urls which need to be downloaded for 'distrubution upgrade' | |
| Printed urls can be used for downloading packages in parallel. | |
| For eg: we can use GNU parallel commanline tool along with wget/curl for parallel downloading | |
| python2 zypper_dup_print_urls.py | parallel --tmuxpane -j4 --colsep ' ' mkdir -p '{1}/{2}' \; cd '{1}/{2}' \; wget -c {3} | |

i3-gaps has some packages that are required for it to work so install these things:
sudo apt install libxcb1-dev libxcb-keysyms1-dev libpango1.0-dev libxcb-util0-dev libxcb-icccm4-dev libyajl-dev libstartup-notification0-dev libxcb-randr0-dev libev-dev libxcb-cursor-dev libxcb-xinerama0-dev libxcb-xkb-dev libxkbcommon-dev libxkbcommon-x11-dev autoconf xutils-dev libtool automake
You also need to install libxcb-xrm-dev, but I got Unable to locate package libxcb-xrm-dev when trying to install from the apt repositories on Ubuntu 16.04. If this happens to you, just install it from source using these commands:
mkdir tmp
