The source code history of Free Pascal and Lazarus visualized with Gource

Gource is a software version control visualization tool. I thought it would be fun to visualize Delphi’s source code with Gource, but that is not possible for obvious reasons. So, I decided to try-out Delphi’s cousins: Free Pascal and Lazarus.

I checked-out the respective code bases and ran them through Gource.

Below are the Gource commands I used:

gource -1280x720 -o C:\\gource\\fpc.ppm -s 0.01 --hide dirnames,filenames,progress,mouse C:\\gource\\fpc

gource -1280x720 -o  C:\\gource\\lazarus.ppm -s 0.01 --hide dirnames,filenames,progress,mouse C:\\gource\\lazarus


Gource shows the filenames and directories of the source code by default; still, I decided to hide them in these videos, because they were overlapping. You can play more with Gource, FPC and Lazarus on your own :-) For a comprehensive list of the command line options and arguments of Gource click HERE.

The above gource calls create two files: fpc.ppm and lazarus.ppm. I guess these are some kind of uncompressed video format. The files were huge: ~60GB and ~100GB respectively.

Then, I used FFmpeg to encode the above .ppm files into .avi files. The FFmpeg commands are below:

ffmpeg -y -r 60 -f image2pipe -vcodec ppm -i C:\\gource\\fpc.ppm -vcodec libx264 -preset ultrafast -pix_fmt yuv420p -crf 1 -threads 0 -bf 0 C:\\gource\\fpc.x264.avi

ffmpeg -y -r 60 -f image2pipe -vcodec ppm -i C:\\gource\\lazarus.ppm -vcodec libx264 -preset ultrafast -pix_fmt yuv420p -crf 1 -threads 0 -bf 0 C:\\gource\\lazarus.x264.avi


Finally, I uploaded fpc.x264.avi and lazarus.x264.avi to YouTube. You can see them below:
