NOTE: These scripts are obsolete, you should use the mjpg-streamer.ipk file published at https://github.com/robotpy/roborio-packages instead.

mjpg-streamer scripts for RoboRIO

This was very quickly put together... so not quite as polished as I would normally like. :)

We used these scripts to run two camera servers on our roboRIO. Very little CPU usage as far as we can see. Only tested with the Microsoft LifeCam 3000 cameras.

# Demonstrates potential buggy behavior in PyGObject+Treeview DnD
#
# Bug is that when do_drag_data_get is called, the selection_data argument
# appears to be discarded and never used, regardless of the return value
#
# This sample program should be executed like so:
#
#    python treetest.py ~/some/path/*

At work, I've been playing a little bit with visualization of data. After hours, I DJ at local Lindy Hop dance events, and it occurred to me recently that it could be interesting to visualize my playlists to understand more about what I actually played. Using Exaile, I'm able to easily add a lot of metadata to the tracks in my collection, and its plugin framework made it easy to take that data and do something interesting with it.

From that initial investigation, I've built in a playlist visualization templating engine plugin for Exaile that can do some very simple visualization stuff, and I'm planning on extending the types of things I can do with it. Here's an interesting one I created from a recent playlist. This visualization was inspired by The Concept Map, except the source code for this isn't minified. :)

The HTML/js was generated by Exaile 3.4-beta3.
