bennylope / brew-cleanup.sh
Created November 22, 2017 20:44
A short script for performing brew cleanup for all but specified packages. The 'cleanup' command can either be used for specific packages or for all - there is no exclusion option - and this means cleanup on older packages that I want.

# Clean all but specified packages of old homebrewed installed packages
declare -a exclude=(python python3 python34 python35 python36 python27 pypy ruby node)
for PACKAGE in $(brew ls)

FFmpeg add a watermark to video

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.
