WasyaCo Models. The functionality shared across all (most) projects, including:

* some javascript
* some controllers and views

= Setup =

Docker is reqiured for development. It is used for mongo (?), and localstack.

Some infrastructure is driven by ansible - therefore, local python3 and ansible are required:

python3 -m venv zenv
. zenv/bin/activate
pip install -r requirements.txt

= Develop / Use =


cmd = "#cmd [ -f newspartial_#idx.mp4 ] || ffmpeg -y -i newspartial_#idx.webm -r 24 -pix_fmt yuv420p newspartial_#idx.mp4 ; "


== Image to video ==

ffmpeg -loop 1 -i $inn -c:v libx264 -t 3 -pix_fmt yuv420p output.mp4

## illustrative image to video, sized

export width=848
export height=480
export duration_sec=3
magick "$inn" -resize "$width}x${height^" -gravity center -extent "$width}x${height" "$inn"
ffmpeg -loop 1 -i $inn -c:v libx264 -t $duration_sec -pix_fmt yuv420p $inn-out.mp4

## image in a news studio

export image=image.jpg ; \
export video_base=base_4_5sec.mp4 ; \
rm output.mp4 ; \
ffmpeg -i $video_base -i $image \
-filter_complex "[1:v]scale='min(iw,420)':-1,pad=iw+20:ih+20:10:10:black[img];[0:v][img]overlay=(W-w)/2:(H-h)/2-50" \
-c:v libx264 -pix_fmt yuv420p -c:a copy output.mp4
