FFmpeg Docker image

This project prepares a minimalist Docker image with FFmpeg. It compiles FFmpeg from sources following instructions from the Compilation Guide.

You can install the latest build of this image by running docker pull jrottenberg/ffmpeg.

This image can be used as a base for an encoding farm.

Builds

There are different builds available:

alpine based images ffmpeg:<version>-alpine38 or ffmpeg:<version>-alpine312 (the ffmpeg:<version>-alpine builds are not updated any more)
- alpine based scratch images ffmpeg:<version>-scratch38 or ffmpeg:<version>-scratch312 (experimental image containing only FFmpeg and libraries, the ffmpeg:<version>-alpine builds are not updated any more)
centos based images ffmpeg:<version>-centos7 or ffmpeg:<version>-centos8
ubuntu based images ffmpeg:<version>-ubuntu1804 or ffmpeg:<version>-ubuntu2004 (the default, you can also use ffmpeg:<version>-ubuntu as an alias)
- ubuntu based nvidia images ffmpeg:<version>-nvidia1804
- ubuntu based vaapi images ffmpeg:<version>-vaapi1804 or ffmpeg:<version>-vaapi2004

<version> can be one of the following:

3.2
3.3

Generate list of recent images

You can use the following command to generate a list of current images:

$ curl --silent https://hub.docker.com/v2/repositories/jrottenberg/ffmpeg/tags/?page_size=500 | jq -cr ".results|sort_by(.name)|reverse[]|.sz=(.full_size/1048576|floor|tostring+\"mb\")|[.name,( (20-(.name|length))*\" \" ),.sz,( (8-(.sz|length))*\" \"),.last_updated[:10]]|@text|gsub(\"[,\\\"\\\]\\\[]\";null)"

If you want to compare the one you have locally, use the following command:

$ docker images | grep ffmpeg | sort | awk '{print $1 ":" $2 "\t" $7 $8}'

Please use Github issues to report any bug or missing feature.

Capture output from the container to the host running the command

 docker run jrottenberg/ffmpeg \
            -i http://url/to/media.mp4 \
            -stats \
            $ffmpeg_options  - > out.mp4

Examples

Extract 5s @00:49:42 into a GIF

 docker run jrottenberg/ffmpeg -stats  \
        -i http://archive.org/download/thethreeagesbusterkeaton/Buster.Keaton.The.Three.Ages.ogv \
        -loop 0  \
        -final_delay 500 -c:v gif -f gif -ss 00:49:42 -t 5 - > trow_ball.gif

Convert 10bits MKV into a 10Bits MP4

 docker run -v $(pwd):$(pwd) -w $(pwd) jrottenberg/ffmpeg:3.4-scratch \
        -stats \
        -i http://www.jell.yfish.us/media/jellyfish-20-mbps-hd-hevc-10bit.mkv \
        -c:v libx265 -pix_fmt yuv420p10 \
        -t 5 -f mp4 test.mp4

The image has been compiled with X265 Multilib. Use the pixel format switch to change the number of bits per pixel by suffixing it with 10 for 10bits or 12 for 12bits.

Convert a local GIF into a mp4

Let's assume original.gif is located in the current directory :

 docker run -v $(pwd):$(pwd) -w $(pwd)\
        jrottenberg/ffmpeg:3.2-scratch -stats \
        -i original.gif \
        original-converted.mp4

Use ZeroMQ to toggle filter value on-fly

Let's start some process continuously writing some radio music, and listen it:

 docker run --rm -d -v $(pwd):$(pwd) -w $(pwd) -p 11235:11235 \
        --name radio-writer jrottenberg/ffmpeg \
        -i http://radio.casse-tete.solutions/salut-radio-64.mp3 \
        -filter_complex '[0:a]volume@vol=1,azmq=bind_address=tcp\\\://0.0.0.0\\\:11235[out]' \
        -map '[out]' ./salut-radio.mp3

 ffplay ./salut-radio.mp3

Now, just toggle its volume on-fly, and hear how it changes:

 docker run --rm --network=host --entrypoint sh jrottenberg/ffmpeg -c \
        'echo "volume@vol volume 2" | zmqsend -b tcp://127.0.0.1:11235'

Send a stream over SRT

Let's send video.mp4 to srt-listener on port 9000 over SRT protocol.

docker run -v $(pwd):$(pwd) jrottenberg/ffmpeg \
       -re -i $(pwd)/video.mp4 -acodec copy -vcodec copy -f mpegts srt://srt-listener:9000?pkt_size=1316

Use hardware acceleration enabled build

Thanks to qmfrederik for the vaapi ubuntu based variant

jrottenberg/ffmpeg:vaapi or jrottenberg/ffmpeg:${VERSION}-vaapi

Run the container with the device attached /dev/dri from your host into the container :

docker run --device /dev/dri:/dev/dri -v $(pwd):$(pwd) -w $(pwd) jrottenberg/ffmpeg:vaapi [...]

Have the Intel drivers up and running on your host. You can run vainfo (part of vainfo package on Ubuntu) to determine whether your graphics card has been recognized correctly.
Run ffmpeg with the correct parameters, this is the same as when running ffmpeg natively.

Use nvidia hardware acceleration enabled build

Thanks to ShaulMyplay for the nvidia based variant

Supports nvenc only on all ffmpeg versions, and hardware decoding and scaling on ffmpeg >= 4.0

Install nvidia latest drivers on host machine.
Install nvidia-docker on host machine.
Run container using "--runtime=nvidia" flag and use supported ffmpeg hwaccel options

Hardware encoding only example:

docker run --runtime=nvidia jrottenberg/ffmpeg:2.8-nvidia -i INPUT -c:v nvenc_h264 -preset hq OUTPUT Full hardware acceleration example: docker run --runtime=nvidia jrottenberg/ffmpeg:4.1-nvidia -hwaccel cuvid -c:v h264_cuvid -i INPUT -vf scale_npp=-1:720 -c:v h264_nvenc -preset slow OUTPUT

See what's inside the beast

docker run -it --entrypoint='bash' jrottenberg/ffmpeg

for i in ogg amr vorbis theora mp3lame opus vpx xvid fdk x264 x265;do echo $i; find /usr/local/ -name *$i*;done
