# `sylph-ci:ffmpeg` — the CI image plus ffmpeg, for `sylpheed-export`.
#
# The exporter shells out to `ffprobe`/`ffmpeg` to transcode the two movies, so
# `cargo run -p sylpheed-export -- export` fails in the plain CI image with
# "run ffprobe -- is it on PATH?". CI itself never runs the exporter, which is
# why its own image does not carry this.
#
#   docker build -t sylph-ci:ffmpeg -f docker/ci/Dockerfile.ffmpeg docker/ci
