Create a video from today's photos taken from the Rasperry Pi Timelapse rig

# Creates a timelapse video of today's photos
# Author: Andre Jacobs
# Overview: 
#   I am using a Raspberry Pi Zero W with the Camera V2 module to take timelapse photography
#   The idea came from:
#       https://blog.alexellis.io/raspberry-pi-timelapse/
#       https://github.com/alexellis/phototimer

# Today's timelapse directory (e.g. 2019/7/12)
TODAY_DIR=`date +"%Y/%-m/%-d"`
TEMP_DIR="/tmp/timelapse"
BASE_DIR=`pwd`
mkdir -p ${TEMP_DIR}

pushd ./ > /dev/null

echo "Creating sequenced filenames"

# Loop through the sequence 0 to 23 (for possible hours)
x=1
for d in `seq 0 23`; do
    # Check if a directory for the hour exists
    HOUR_DIR=${TODAY_DIR}/${d}
    if [[ -d "${HOUR_DIR}" ]]; then      
        # For each jpg image
        for i in ${HOUR_DIR}/*.jpg; do
            FULL_PATH=${BASE_DIR}/${i}
            counter=$(printf %06d $x)
            x=$(($x+1))
            # Create a symlink
            ln -s "${FULL_PATH}" "${TEMP_DIR}/img$counter.jpg"
        done
    fi
done

echo "Creating timelapse"

cd ${TEMP_DIR}
TODAY_VID=`date +"%Y-%m-%d_timelapse.mp4"`
TODAY_VID_PATH=${BASE_DIR}/${TODAY_VID}
ffmpeg -r 24 -i img%06d.jpg -s hd1080 -vcodec libx264 ${TODAY_VID_PATH}

popd > /dev/null

rm -rf ${TEMP_DIR}

I am currently syncing the timelapse photos from the Raspberry Pi to my Mac using rsync:

rsync -av [email protected]:/var/image/ ./

and then I run the makevid.sh script.

The next iteration would be to get my Linux server up and running and then have the Pi rsync every hour or so to my server.
The server will then run a cron job at the end of everyday to create the video of the day.
