How-to

Prerequisites:

  1. You can sftp into your comma using something like sftp comma@$MY_COMMA_IP

Getting started

  1. Change the COMMA_AI_IP variable in the script to the IP address for your comma.ai device.
  2. Source the functions into your shell
    • Copy and paste, . filename.sh, etc..
  3. Run the command with the second half of route_name for the route you want to download as the first argument and the local directory where you want to save the files as the second argument.

Example:

comma-download "2022-03-22--18-50-33*" ~/Downloads/2022-03-22--18-50-33

And then to overlay the driver camera on the driving video.. something like this:

cat /Users/sgtpooki/Downloads/2022-03-22--18-50-33/*/ecamera.hevc > /Users/sgtpooki/Downloads/2022-03-22--18-50-33/ecamera-all.hevc
cat /Users/sgtpooki/Downloads/2022-03-22--18-50-33/*/dcamera.hevc > /Users/sgtpooki/Downloads/2022-03-22--18-50-33/dcamera-all.hevc
cat /Users/sgtpooki/Downloads/2022-03-22--18-50-33/*/fcamera.hevc > /Users/sgtpooki/Downloads/2022-03-22--18-50-33/fcamera-all.hevc

ffmpeg -r 20 -i /Users/sgtpooki/Downloads/2022-03-22--18-50-33/ecamera-all.hevc -c copy /Users/sgtpooki/Downloads/2022-03-22--18-50-33/ecamera-all.mp4
ffmpeg -r 20 -i /Users/sgtpooki/Downloads/2022-03-22--18-50-33/dcamera-all.hevc -c copy /Users/sgtpooki/Downloads/2022-03-22--18-50-33/dcamera-all.mp4
ffmpeg -r 20 -i /Users/sgtpooki/Downloads/2022-03-22--18-50-33/fcamera-all.hevc -c copy /Users/sgtpooki/Downloads/2022-03-22--18-50-33/fcamera-all.mp4

cd /Users/sgtpooki/Downloads/2022-03-22--18-50-33

ffmpeg -r 20 -thread_queue_size 64 -i ecamera-all.mp4 -vf 'movie=dcamera-all.mp4, scale=300:-1[inner];[in][inner]overlay=main_w-(overlay_w+10):main_h-(overlay_h+10) [out]' combined.mp4
