  • Possibilité de déploiement en ferme

    12 avril 2011, par

    MediaSPIP 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 (...)

  • ffmpeg : unable to use hardware encoder h264_rkmpp with software decoded ATSC OTA transmission

    20 août 2020, par Brad Bruggemann

    When attempting to hardware encode to h264 using the Rockchip MPP encoder h264_rkmpp from an ATSC source, FFMPEG errors out with :

    


    "Impossible to convert between the formats supported by the filter 'Parsed_null_0' and the filter 'auto_scaler_0'"

    


    The sample file used in this example can be downloaded here : https://transfer.sh/BRMej/out.ts

    


    The full command used and resulting output is as follows :

    


    $ ffmpeg -loglevel 48 -c:v mpeg2video -f mpegts -i out.ts -f mp4 -c:v h264_rkmpp -c:a libfdk_aac -preset ultrafast -mbd rd -copyinkf -flags +ilme+ildct -fflags +genpts out.mp4 -y

  • Is it possible to download files (MP4) from external server and convert it to MP3 in NodeJS

    19 mai 2021, par GrayGalaxy

    I am currently working on a chrome extension to download songs from JioSaavn.com. In my implementation I use an Vercel instance as a prox. This is a workaround for CORS error in the extension. The server code is shown as below.

    


    const axios = require('axios')
module.exports = (req, res) => {
    res.setHeader('Access-Control-Allow-Origin', '*')
    res.setHeader('Cache-Control', 's-maxage=300, stale-while-revalidate')
    const URL = req.url // requested url
    // get array buffer
    if (url === '/') return res.redirect('https://github.com/GrayGalaxy/jiosaavn-downloader')

    let server_url = `https://snoidcdnems02.cdnsrv.jio.com/c.saavncdn.com/${URL}`
    axios.get(src_url, { responseType: 'arraybuffer' })
        .then(r => r.data)
        .then(result => res.send(result))
        .catch(() => {
            res.status(400).send('Cannot access the requested URL')
        })
    }
}



    


    This outputs a MP4 file (just with audio). As for example if you put /983/01100b84f61ca8b3a0432f12c564be8e_96.mp4 as the URL parameter it will output as MP4.

    


    Now I want to convert that response MP4 to a MP3 file. I tried ffmpeg, fluent-ffmpef and many other implementation. Most of them dose not support ArrayBuffer as an input (I think) it doesn't provide any output as expected. Or it might possible Vercel does not allow file-browser.

    


    Please give a solution to that.
