Je travaille actuellement sur un projet et presque prêt à être déployé, mais il y a un problème: le code qui fonctionne parfaitement sur ma machine Ubuntu 16.04 (Elementary OS Loki) ne fonctionne pas dans le conteneur Docker. Quel pourrait être le problème dans mon code?Erreur Ffmpeg dans Docker Container: ffmpeg est sorti avec le code 1:
Voici mon Dockerfile:
FROM beevelop/nodejs-python:latest
RUN apt-get -y update && apt-get install -y libav-tools
RUN ffmpeg --help
# Global install yarn package manager
RUN apt-get update && apt-get install -y curl apt-transport-https && \
curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | apt-key add - && \
echo "deb https://dl.yarnpkg.com/debian/ stable main" | tee /etc/apt/sources.list.d/yarn.list && \
apt-get update && apt-get install -y yarn
WORKDIR /app
COPY package.json .
RUN yarn
COPY . .
RUN yarn prod:build
EXPOSE 8080
CMD [ "yarn", "start" ]
je lance sudo docker exec -it <container-name> ffmpeg --help et sorties l'impression d'aide attendue. Dans mon code, télécharger une vidéo Youtube en format mp4 avec ce code:
const download = idParam => (
new Promise((fulfill, reject) => {
const id = `http://www.youtube.com/watch?v=${idParam}`
let videoMeta
youtubedl(id, ['--format=36'], { cwd: __dirname })
.on('info', (info) => {
const customDimensions = calculateCustomDimensions(info.format)
videoMeta = { ...info, ...customDimensions }
})
.pipe(fs.createWriteStream(`temp/${idParam}.mp4`))
.on('finish',() => {
console.log('Dirname: ', __dirname)
fulfill(videoMeta)
})
.on('error', (err) => {
console.log('There is an error:', err)
console.log('Dirname: ', __dirname)
reject(err)
})
})
)
Et puis essayer de traiter la vidéo avec Fluent-ffmpeg:
const processVideo = (videoName, cropStart, cropEnd) => (
new Promise((resolve, reject) => {
try {
console.log('Trying to run ffmpeg binary.')
ffmpeg()
.addInput(`temp/${videoName}.mp4`)
.seekInput(cropStart)
.duration(cropEnd)
.outputOption('-movflags frag_keyframe+faststart')
.on('end',() => {
console.log('Processing has finished with ffmpeg. ')
console.log('Resolved for upload: ', [`temp/cropped_${videoName}.mp4`, `temp/${videoName}.mp4`])
console.log('Going out of processVideo script.')
resolve([`temp/cropped_${videoName}.mp4`, `temp/${videoName}.mp4`])
})
.on('error', (err, stdout, stderr) => {
console.log('Error. Output option olmasına rağmen: ', err.message)
console.log('ffmpeg output:\n', stdout)
console.log('ffmpeg stderr:\n', stderr)
})
.save(`temp/cropped_${videoName}.mp4`)
} catch (e) {
console.log('There has been an error while converting ffmpeg binary!')
console.log(e.msg)
console.log(e.code)
reject(e)
}
})
)
Il donne l'erreur suivante:
