GeoTools Code Visualisation

Managed to create a small movie showing recent commits to the GeoTools repository:

Here is an attempt at an embedded iframe; however this is not showing up on; so try the above link...

Visualisation was created with gource which installed quite nicely on a mac using "brew install gource". The result is an interactive visualisation you can use to visually explore what developers have been up to.

The second step was to make a movie using "ffmpeg" where I had a bit of install trouble (resolved here).

Here is what that looked like on the command line:

gource -title GeoTools -1280x720 --auto-skip-seconds 1 --background 333333 --font-colour EDEDED --seconds-per-day 0.1 -o geotools.ppm
ffmpeg -y -b 10000K -r 60 -f image2pipe -vcodec ppm -i geotools.ppm -vcodec libx264 -vpre slow -threads 0 -bf 0 geotools.x264.mp4
