Visualization of Haiku git repository activity - January 8th, 2015 update

Here is another update of the Haiku git repository Gource visualization. The last one I did of this was well over 2 years ago, and I've been meaning to do a new and improved one ever since.

For convenience I'll include the full description here;

Visualization of activity on the Haiku OS git repository done with Gource.

https://www.haiku-os.org/ http://code.google.com/p/gource/ https://www.haiku-os.org/guides/building/get-source-git

I used a combination of the Gravatar script ( http://code.google.com/p/gource/wiki/GravatarExample ) and some custom done icons for some of the users, replaced the default user icon with a modified "People" icon from Haiku, dropped in the Haiku logo, and did a number of other tweaks.

Command line:

gource --load-config gource.cfg -r 25 -o gource.ppm

Encoding line:

ffmpeg -y -i audio.mp3 -vcodec ppm -r 88 -f image2pipe -i gource.ppm -vcodec mpeg4 -r 29.97 -preset veryslow -q:v 1 -threads 8 -b:v 10000k -bf 0 -comp_duration 204 -ac 2 -acodec copy gource.mp4

Config file:

[display]
viewport=1920x1080

[gource]
auto-skip-seconds=0.01
camera-mode=overview
default-user-image=person.png
font-size=24 font-colour=ff7600

As you might notice, I did this one in full 1080p this time around and the video quality came out far better.

The music in the video is from "Flight of the Bumblebee", which seemed perfectly fitting to the frenetic pace of the development shown in the video.

Updated Gource visualization of the Haiku Git repository

I had done a version of this around 5 months ago, but had a few glitches in it due to features that weren't working at the time (since fixed), and some bugs in the physics parts of Gource that I since learned how to work around... so recently in response to a request for an updated version in relation to an upcoming Haiku on-line conference, "Haiku Down Under 2012 - Beta Blockers", I decided to tackle it again and make a slightly improved version.

Just to be clear, the conference starts tomorrow morning Australian time, but actually tonight at 7PM EST time (Sunday 19st August, 2012 - 9AM (GMT +10))! So be sure not to miss it! See the conference website for more information. Also try this time zone converter: http://wwp.greenwichmeantime.com/gmt-converter/ I found it easier to use than the one linked on the conference website.

This is about as good as I could get the video without the size being too excessive.

I also kept having trouble with YouTube making all my video uploads into grey pixelated useless garbage. :( So I'm trying this one as MPEG4 to see if it makes a difference.

I might do a nice 1080p copy of this after my new monitor arrives, if I can get this YouTube video scrambling problem figured out, and if I can free up enough disk space.

I decided to add music to this version on the suggestion of someone in #haiku... and I think it adds a fun little twist to it. The selection I used was "Flight of the Bumblebee", which seemed perfectly fitting to the frenetic pace of the development shown in the video.
