How to Add a Watermark to Video

FFMPEG filters provide a powerful way to programmatically enhance or alter videos, and it’s fairly simple to add a watermark to a video using the overlay filter. The easiest way to install ffmpeg is to download a pre-built binary for your specific platform. Then you don’t have to worry about including and installing all the right dependencies and codecs you will be using.

Once you have ffmpeg installed, adding a watermark is as easy as passing your existing source through an overlay filter like so:

ffmpeg -i test.mp4 -i watermark.png -filter_complex "overlay=10:10" test1.mp4

Basically, we’re passing in the original video, and an overlay image as inputs, then passing it through the filter, and saving the output as test1.mp4.

# follow instructions on http://caffe.berkeleyvision.org/install_osx.html except for protobuf, where you should use --devel and not use --with-python because it is the default behaviour
brew install --devel protobuf #basically you are installing protobuf 3.0, the same checked by pip for tensorflow

Using Git to Manage a Live Web Site

Overview

As a freelancer, I build a lot of web sites. That's a lot of code changes to track. Thankfully, a Git-enabled workflow with proper branching makes short work of project tracking. I can easily see development features in branches as well as a snapshot of the sites' production code. A nice addition to that workflow is that ability to use Git to push updates to any of the various sites I work on while committing changes.

Theory of Building Caffe on OS X

Introduction

Our goal is to run python -c "import caffe" without crashing. For anyone who doesn't spend most of their time with build systems, getting to this point can be extremely difficult on OS X. Instead of providing a list of steps to follow, I'll try to explain why each step happens.

This page has OS X specific install instructions.

/* open up chrome dev tools (Menu > More tools > Developer tools)
 * go to network tab, refresh the page, wait for images to load (on some sites you may have to scroll down to the images for them to start loading)
 * right click/ctrl click on any entry in the network log, select Copy > Copy All as HAR
 * open up JS console and enter: var har = [paste]
 * (pasting could take a while if there's a lot of requests)
 * paste the following JS code into the console
 * copy the output, paste into a text file
 * open up a terminal in same directory as text file, then: wget -i [that file]
