is there a possibility to run gource (scm-visualizer) completely without gui and windows? I just want to render the video to a file. This is possible with commands like:
gource --output-ppm-stream - | ffmpeg ..
Gource uses OpenGL for drawing and just optionally writes out the rendered frames afterwards, so it cannot run without a display.
https://github.com/acaudwell/Gource/wiki/Videos even mentions that the window should remain completely visible to avoid output problems.
Appenrently it can be used without a physical display with the help of xvfb-run, see https://github.com/FrankM1/gource/issues/29
