Thanks for letting me know about the video playback issue, I used the following script to create the timelapse:

  ffmpeg \
   -pattern_type glob \
   -framerate 30 \
   -i "img/*.JPG" \
   -i "star_wars_style_march.mp3" \
   -s:v 1920x1080 \
   -c:a libopus \
   -c:v vp9 \
   -shortest \
   deathstar_timelapse.webm

I actually thought that VP9 and Opus are well supported everywhere by now, but maybe that is not the case…

Regarding GitLab, as a general rule, I try to avoid products dominating the market, and I quite like their OSS policy…

I have converted the timelapse to H.264/AAC, hope this plays everywhere now.

Android Firefox says it won't play because it's corrupted.

VP9/WEBM should be supported by all modern browsers: https://caniuse.com/webm

You should have used mp4. Not all browsers support vp9.
