Development

I've Dockerized dependencies you need for serving the project. The only two things you need installed locally are Docker and Make. The Make target will automatically build a Docker image with the required dependencies.

Run make help to see the available commands.

Scripts

Some scripts I've used when writing articles.

Encode video to WebM

Encode a video to WebM. Make sure to adjust the dimensions to match the aspect ratio of the original video.

ffmpeg -i <in> -s 720x1280 -vcodec libvpx -acodec libvorbis output.webm

Use the --b:v flag to adjust the average bit rate (e.g. --b:v 1000K) Use the -crf flag to specify a quality that the encode will attempt to maintain (e.g. --crf 10)

Encode video to GIF

ffmpeg -i <in> -vf "fps=10,scale=<width>:-1:flags=lanczos,split[s0][s1];[s0]palettegen[p];[s1][p]paletteuse" -loop 0 output.gif
