Create animated GIF and WebP from videos using ffmpeg
ffmpeg -ss $INPUT_START_TIME -t $LENGTH -i $INPUT_FILENAME \
-vf "fps=$OUTPUT_FPS,scale=$OUTPUT_WIDTH:-1:flags=lanczos,split[s0][s1];[s0]palettegen[p];[s1][p]paletteuse" \
-loop $NUMBER_OF_LOOPS $OUTPUT_FILENAME
# Change these placeholders:
# * $INPUT_START_TIME - number of seconds in the input video to start from.
# * $LENGTH - number of seconds to convert from the input video.
# * $INPUT_FILENAME - path to the input video.
# * $OUTPUT_FPS - ouput frames per second. Start with `10`.
# * $OUTPUT_WIDTH - output width in pixels. Aspect ratio is maintained.

This tutorial shows how to run docker natively on Android, without VMs and chroot.

Docker on Android 🐋📱

Edit 🎉

All packages, except for Tini have been added to termux-root. To install them, simply pkg install root-repo && pkg install docker. This will install the whole docker suite, left only Tini to be compiled manually.
