wader/static-ffmpeg

static-ffmpeg

Docker image with ffmpeg and ffprobe built as hardened static PIE binaries with no external dependencies that can be used with any base image.

See Dockerfile for versions used. In general, master should have the latest stable version of ffmpeg and below libraries. Versions are kept up to date automatically using bump.

Usage

Use mwader/static-ffmpeg from Docker Hub or build image yourself.

In Dockerfile

COPY --from=mwader/static-ffmpeg:6.1 /ffmpeg /usr/local/bin/
COPY --from=mwader/static-ffmpeg:6.1 /ffprobe /usr/local/bin/

Run directly

docker run -i --rm -u $UID:$GROUPS -v "$PWD:$PWD" -w "$PWD" mwader/static-ffmpeg:6.1 -i file.wav file.mp3
docker run -i --rm -u $UID:$GROUPS -v "$PWD:$PWD" -w "$PWD" --entrypoint=/ffprobe mwader/static-ffmpeg:6.1 -i file.wav

As shell alias

alias ffmpeg='docker run -i --rm -u $UID:$GROUPS -v "$PWD:$PWD" -w "$PWD" mwader/static-ffmpeg:6.1'
alias ffprobe='docker run -i --rm -u $UID:$GROUPS -v "$PWD:$PWD" -w "$PWD" --entrypoint=/ffprobe mwader/static-ffmpeg:6.1'

Tags

latest Latest master build.

MAJOR.MINOR.PATCH[-BUILD] Specific version of FFmpeg with the features that was in master at the time of tagging. -BUILD means that was an additional build with that version to add of fix something.

Security

Binaries are built with various hardening features but it's still a good idea to run them as non-root even when used inside a container, especially so if running on input files that you don't control.

libfdk-aac

Due to license issues the docker image does not include libfdk-aac by default. A docker image including libfdk-aac can be built by passing a non empty value to the build-arg ENABLE_FDKAAC, example below.

docker build --build-arg ENABLE_FDKAAC=1 . -t my-ffmpeg-static:latest

Known issues and tricks

Multi-arch and arm64

Since version 5.0.1-3 dockerhub images are multi-arch amd64 and arm64 images.

Copy out binaries from image

This will copy ffmpeg and ffprobe to the current directory:

docker run --rm -v "$PWD:/out" $(echo -e 'FROM alpine\nCOPY --from=mwader/static-ffmpeg:latest /ff* /\nENTRYPOINT cp /ff* /out' | docker build -q -)

Quickly see what versions an image was built with

docker run --rm mwader/static-ffmpeg -v quiet -f data -i versions.json -map 0:0 -c text -f data -

I see Name does not resolve errors for hosts that should resolve

This could happen if the hostname resolve to more IP-addresses than can fit in DNS UDP packet (probably 512 bytes) causing the response to be truncated. Usually clients should then switch to TCP and redo the query. This should only be a problem with version 6.0-1 or earlier of this image that uses musl libc 1.2.3 or older.

TLS

Binaries are built with TLS support but, by default, ffmpeg currently do not do certificate verification. To enable verification you need to run ffmpeg with -tls_verify 1 and -ca_file /path/to/cert.pem.

• Alpine Linux at /etc/ssl/cert.pem
• Debian/Ubuntu install the ca-certificates package at it will be available at /etc/ssl/certs/ca-certificates.crt.

Docker Hub images

Multi-arch dockerhub images are built using pldin601/build-multiarch-on-aws-spots. See build-multiarch.yml for config. Thanks to @pldin601 for making this possible.
