For video only: ffmpeg -i /storage/emulated/0/ffvid/frameCount.mp4 -vf reverse reversed.mp4 For audio and video: ffmpeg -i KALIA1.mp4 -strict -2 -vf reverse -af areverse reversed.mp4 This filter buffers the entire clip. For larger files, segment the file, reverse each segment and then concat the reversed segments.

Conceptual thinking vs programming

Programming language, poetry, performance, sound

different experiments with videos, python using raspberry pi as a tool for organising, documenting, communicating some wiki skills
