Use a Kubernetes Job and Kaniko to build an OpenFaaS function from Git
# Alex Ellis 2018
# Example from: https://blog.alexellis.io/quick-look-at-google-kaniko/
# Pre-steps:
# kubectl create secret generic docker-config --from-file $HOME/.docker/config.json
# Other potential optimizations (suggested by @errordeveloper)
# - Store "templates" in a permanent volume
# - Download source via "tar" instead of git clone

ffmpeg time-lapse

Convert sequence of JPEG images to MP4 video

ffmpeg -r 24 -pattern_type glob -i '*.JPG' -i DSC_%04d.JPG -s hd1080 -vcodec libx264 timelapse.mp4

  • -r 24 - output frame rate
  • -pattern_type glob -i '*.JPG' - all JPG files in the current directory
  • -i DSC_%04d.JPG - e.g. DSC_0397.JPG
  • -s hd1080 - 1920x1080 resolution

Slower, better quality
