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
