Yeah, that trick is also useful for older machines which are otherwise too slow to play stutter-free youtube video in a web browser. The VLC implementation appears to be significantly more CPU efficient.
Probably pulls the h264 version instead of VP8/9.

What was that 3D/CAD software you were using?
The lines are drawn and then certain constraints must be applied: These points must be coincident, these lines must be parallel, these must be perpendicular and several others. Dimensional constraints are then applied. The program informs the designer when the drawing is "fully constrained" meaning that the parametric solver can only find a single solution for the given set of constraints.
For example to center a hole inside a brick: Guide lines are drawn to be along the center. At there intersection a point is constrained. The hole is then extruded (or made using the hole tool) at this point.
This allows for making programmable drawings. For example one drawing can generate several pieces of documentation for different parts, but with different dimensions, thread types and so on.

It looked like Autodesk Inventor. It is a parametric CAD software like Creo or Solidworks. The parametric part is actually really neat.

Dimensional constraints are then applied. The program informs the designer when the drawing is "fully const…

Agreed, my neighbors probably hate me right now from the audio. On a serious note, though, I hope a write up with more details pops up.
This was bad enough that I bothered to figure out how to fix it. VLC -> Media -> Open Network Stream, paste in the youtube URL. VLC -> Tools -> Effects and Filters -> Audio Effects -> Compressor. Enable the compressor. Here's where I moved the sliders: http://i.imgur.com/fGlPM5R.png I basically followed the advice given here: http://lifehacker.com/5920290/how-to-fix-movies-that-are-rea...
