Tools for work creating animating gifs for the OLED

[glowmouse]

I'm not sure if we need any specialised tools for creating animating gifs. So far I've been using ffmpeg for proof of concept stuff. Maybe treat this issue as an investigation/ process documentation ticket.

Some ffmpeg commands that I found useful enough to record

Recipe for a horizontal flip.

ffmpeg -i "1.mp4" -vf hflip -i audio1.mp3 -map 0:v -map 1:a -c:v copy -shortest "C:\Users\Admin\Desktop\Replaced Mp3\1.mp4"

Recipe to merge two animations and put them side by side. Useful when your display is short and wide.

ffmpeg -i left.mp4 -i right.mp4 -filter_complex hstack output.mp4

Recipe for conversion to black and white of a 1280x720 input image

ffmpeg -i main_1280x720.mp4 -f lavfi -i color=gray:s=1280x720 -f lavfi -i color=black:s=1280x720 -f lavfi -i color=white:s=1280x720 -filter_complex threshold output.mkv
