• Express - FFMPEG : Serve transcoded video instead of static video file

  30 septembre 2020, par No stupid questions

  I am creating a website to host videos downloaded on my computer online. However, many of these videos are not in a web friendly format (like .mkv or .flv). It is not an option to convert these files on the disk and then serve them as static files, converting needs to be done live by the server. I want to transcode these videos with ffmpeg to a web friendly format like webm.

  


  So far, I have been able to somewhat successfully transcode a video and serve it :

  


  import express from 'express';
import cors from 'cors';
import ffmpeg from 'fluent-ffmpeg';

const app = express();

app.use(cors());
app.use(express.json());

app.use('/static/videos', globalPasswordMiddleware, (req, res) => {
    res.contentType('webm');
    const videoPath = path.join('C:/videos', decodeURIComponent(req.path));
    ffmpeg(videoPath)
        .format('webm')
        .on('end', function () {
            console.log('file has been converted succesfully');
        })
        .on('error', function (err) {
            console.log('an error happened: ' + err.message);
        })
        .pipe(res, { end: true });
});


  


  However, I am still encountering three different issues :

  


  Firstly, while this code seems to work for transcoding something like a flash video into webm, there are still a number of videos I cannot get to play. For example, a number of videos that play in Chrome will still not play in Firefox or a number of videos that play on my PC won't on my ancient iPad. Are there more arguments I need to be passing to ffmpeg to transcode the video in a way that it will work on a greater number or devices/browsers ?

  


  Second, there is no ability to seek on the video or see how much time remains. When viewing a transcoded video it behaves more like a livestream than if I were serving it as a static file. How can I fix this ?

  


  And finally third, the transcoding is massively slow. Running in production mode, video playback has to buffer for a few seconds every five or so seconds. I am aware transcoding video is an intense process but I believe given my computer's hardware (i9 9900K) and how much faster it is at transcoding videos on Plex that I should be able to transcode videos faster than this.

  


• AWS Lambda Layer FFMPEG in Express API not working

  11 octobre 2020, par WorkoutBuddy

  This is the code I have in my lambda function :

  


  app.post('/api/youtube/download', async (req, res) => {
    const body = req.body;
    const { url } = body;

    res.header('Content-disposition', 'attachment; filename=video.mp3');


    const youTubeStream = await youTube.getStream(url);


    console.log('before convertig')
    const result = spawnSync("/opt/bin/ffmpeg", ['-i', youTubeStream,'-vn', '-ar', '44100', '-ac','2','-b:a','192k', '/tmp/file.mp3'], { stdio: 'inherit' })
    console.log(result)
    const output = result['output']
    console.log(output.toString())
    console.log('after converting')
    const stream = await fs.createReadStream('/tmp/file.mp3')
    stream.pipe(res)
}
