Possibilité de déploiement en ferme
12 avril 2011, parMediaSPIP peut être installé comme une ferme, avec un seul "noyau" hébergé sur un serveur dédié et utilisé par une multitude de sites différents.
Cela permet, par exemple : de pouvoir partager les frais de mise en œuvre entre plusieurs projets / individus ; de pouvoir déployer rapidement une multitude de sites uniques ; d’éviter d’avoir à mettre l’ensemble des créations dans un fourre-tout numérique comme c’est le cas pour les grandes plate-formes tout public disséminées sur le (...) -

How to speed up video and its timestamp to shorten video length, but represent time as it was recorded ?
7 janvier 2021, par Gonzalo AspeeI have a video recorded at 5 fps that I want to speed up to 30 fps to shorten it. That is simple enough as :


ffmpeg -i input.mp4 -r 30 -vf "setpts=0.16666*PTS" output.mp4


But when I try to add a timestamp to it with :


ffmpeg -i input.mp4 -r 30 -vf "setpts=0.16666*PTS, drawtext=text='%{pts\:localtime\:1610043985\:%Y\-%m\-%d %H\\\\\:%M\\\\\:%S.}%{eif\:mod(n,30)\:d}'" output.mp4


The timestamp does not longer represents the time as it was recorded (it should run faster now)


How to achieve this ?

How to create m3u8 playlist from mp4 video url ( stored in amazon S3 ) and store the video chunks ( .ts files) and .m3u8 file back to another S3 ?
19 mai 2019, par dexter2019I am building an application where user can upload video and others can watch them later. I am aiming for HLS streaming of the video on the client side, for which the video format should be .m3u8. I am using node fluent-FFmpeg module to do the processing, however, I have a huge doubt, that, how to ensure that all the .ts files (chunks) are also stored back in s3 bucket along with the m3u8 file after ffmpeg processed the mp4 file ?
Because the ffmpeg command only takes the location of the m3u8 file ? How handle it when I want the input and output location to be S3 ?
Any help will be greatly appreciated.
I am following the answer from this question Ffmpeg creating m3u8 from mp4, video file size , which is working absolutely fine in my local machine, how to achieve the same for s3 ?

ffmpeg converted video from s3 bucket downloads before playing the video
12 octobre 2020, par RutuI making a video streaming application with react and node js.
I am converting video into different resolution with ffmpeg and storing directly to S3 bucket with the help of piping.


I am streaming uploaded resolution video from S3 bucket directly through cloudfront in HTML5 tag with video.js


When i tried to play original video through cloudfront in player its working fine, But as soon i play ffmpeg converted video to video player in cloudfront i am facing issue :


Video takes a lot load (Downloads in browser) before playing in player.


Below is my ffmpeg command


await loadProcess( [
'i',<s3 url="url" of="of" original="original" video="video">,
 '-movflags',
 'frag_keyframe+empty_moov','-vf', 'scale=-2:360','-c:v','h264','-profile:v','baseline','-r',30,'-g', 60,'-b:v','1M','-f','mp4','-']
, outPath,'video/mp4')

</s3>

this is my loadProcess function : i am using aws cli to direct upload resolution video to S3 bucket :


export function loadProcess(ffmpegOptions, outPath,contentType) {
 return new Promise((resolve, reject) => {
 const videoPath = outPath.replace(/\\/g, "/");
 let ffmpeg = spawn(conf.ffmpeg, ffmpegOptions);
 let awsPipe = spawn('aws', ['s3', 'cp', '--content-type', `${contentType}`, '-', `s3://${process.env.AWS_S3_BUCKET}/${process.env.AWS_S3_VIDEOS_FOLDER}${videoPath}` ])
 ffmpeg.stdout.pipe(awsPipe.stdin)

 // ffmpeg write stream flow
 let ffmpegData = ''
 ffmpeg.stderr.on('data', (_data) => {
 ffmpegData += _data.toString();
 })
 ffmpeg.on('close', (code) => {
 if (code === 0) {
 resolve(outPath)
 }
 else {
 let _dataSplit=ffmpegData.split('\n');
 _dataSplit.pop();
 console.log({action: 'close', message:_dataSplit.pop(), more:[conf.ffmpeg].concat(ffmpegOptions).join(' ')+'\n'+ffmpegData, code})
 }
 });
 ffmpeg.on('error', (err) => {
 reject({action: ' ffmpeg error', message: err});
 });
 
 // aws s3 cli read stream pipe flow
 let awsPipeData = ''
 awsPipe.stderr.on('data', _data => {
 awsPipeData += _data.toString()
 });
 awsPipe.on('close', (code) => {
 if (code === 0) {
 resolve(outPath)
 }else{
 console.log({action: 'close', message: awsPipeData})
 }
 });
 awsPipe.on('error', (err) => {
 reject({action: 'awsPipe error', message: err});
 })

 })
}


I have tried using +faststart option in ffmpeg but getting command failed error.
Can someone please help me this ?


Thanks in advance
