static-ffmpeg

Docker image with ffmpeg, ffprobe and qt-faststart binaries built as hardened static PIE binaries with no external dependencies. Can be used with any base image even scratch.

Built with gray, openssl, iconv, libxml2, libmp3lame, libfdk-aac, libvorbis, libopus, libmodplug, libtheora, libvpx, libx264, libx265, libwebp, libwavpack, libspeex, libaom, libvidstab, libkvazaar, libfreetype, fontconfig, libfribidi, libass, libzimg, libsoxr, libopenjpeg, libdav1d, libxvid, librav1e, libsrt, libsvtav1, libdavs2, libxavs2, libvmaf and all default native ffmpeg codecs, formats, filters etc.

Usage

Use mwader/static-ffmpeg from docker hub or build image yourself.

In Dockerfile

COPY --from=mwader/static-ffmpeg:4.4.0 /ffmpeg /usr/local/bin/
COPY --from=mwader/static-ffmpeg:4.4.0 /ffprobe /usr/local/bin/
COPY --from=mwader/static-ffmpeg:4.4.0 /qt-faststart /usr/local/bin/

Run directly

docker run -i --rm -u $UID:$GROUPS -v "$PWD:$PWD" -w "$PWD" mwader/static-ffmpeg:4.4.0 -i file.wav file.mp3
docker run -i --rm -u $UID:$GROUPS -v "$PWD:$PWD" -w "$PWD" --entrypoint=/ffprobe mwader/static-ffmpeg:4.4.0 -i file.wav
docker run -i --rm -u $UID:$GROUPS -v "$PWD:$PWD" -w "$PWD" --entrypoint=/qt-faststart mwader/static-ffmpeg:4.4.0 file.mov out.mov

Bash alias

alias ffmpeg='docker run -i --rm -u $UID:$GROUPS -v "$PWD:$PWD" -w "$PWD" mwader/static-ffmpeg:4.4.0'
alias ffprobe='docker run -i --rm -u $UID:$GROUPS -v "$PWD:$PWD" -w "$PWD" --entrypoint=/ffprobe mwader/static-ffmpeg:4.4.0'
alias qt-faststart='docker run -i --rm -u $UID:$GROUPS -v "$PWD:$PWD" -w "$PWD" --entrypoint=/qt-faststart mwader/static-ffmpeg:4.4.0'

Security

Binaries are built with various hardening features but it's probably 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.

Known issues

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 but musl libc does currently not support DNS over TCP.

TLS

Binaries are built with TLS support but by default ffmpeg currently do not do certificate verifications. To enable verification you need to run ffmpeg with -tls_verify 1 and -ca_file /path/to/cert.pem. For alpine the ca file is included by default at /etc/ssl/cert.pem and for debian/ubuntu you have to install the ca-certificates package which will install the file at /etc/ssl/certs/ca-certificates.crt.

TODOs and possible things to add

• Add libuavs3d (releases missing? uavs3/uavs3d#11)
• Add acceleration support (GPU, CUDA, ...)
• Add *.a *.so libraries, headers and pkg-config somehow
• Use cargo-c stable alpine package (uses edge/testing now)
