• ffmpeg converted video from s3 bucket downloads before playing the video

  12 octobre 2020, par Rutu

  I 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( [&#xA;&#x27;i&#x27;,<s3 url="url" of="of" original="original" video="video">,&#xA;  &#x27;-movflags&#x27;,&#xA;  &#x27;frag_keyframe&#x2B;empty_moov&#x27;,&#x27;-vf&#x27;, &#x27;scale=-2:360&#x27;,&#x27;-c:v&#x27;,&#x27;h264&#x27;,&#x27;-profile:v&#x27;,&#x27;baseline&#x27;,&#x27;-r&#x27;,30,&#x27;-g&#x27;, 60,&#x27;-b:v&#x27;,&#x27;1M&#x27;,&#x27;-f&#x27;,&#x27;mp4&#x27;,&#x27;-&#x27;]&#xA;, outPath,&#x27;video/mp4&#x27;)&#xA;&#xA;</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});
        })

    })
}
