  • MediaSPIP 0.1 Beta version

    25 avril 2011, par

    MediaSPIP 0.1 beta is the first version of MediaSPIP proclaimed as "usable".
    The zip file provided here only contains the sources of MediaSPIP in its standalone version.
    To get a working installation, you must manually install all-software dependencies on the server.

  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • Problems piping ffmpeg to flac encoder

    19 mai 2019, par Sebastian Olsen

    I need to encode a flac file with seektables, ffmpeg’s flac encoder does not include seektables, so I need to use the flac CLI. I’m trying to make it possible to convert any arbitrary audio file to a seekable flac file by first piping it through ffmpeg, then to the flac encoder.

    export const transcodeToFlac: AudioTranscoder<{}> = ({
    
  source,
    
  destination
    
}) => {
    
  return new Promise((resolve, reject) => {
    
    let totalSize = 0
    

    
    const { stdout: ffmpegOutput, stderr: ffmpegError } = spawn("ffmpeg", [
    
      "-i",
    
      source,
    
      "-f",
    
      "wav",
    
      "pipe:1"
    
    ])
    

    
    const { stdout: flacOutput, stdin: flacInput, stderr: flacError } = spawn(
    
      "flac",
    
      ["-"]
    
    )
    

    
    flacOutput.on("data", (buffer: Buffer) => {
    
      totalSize += buffer.byteLength
    
    })
    

    
    ffmpegError.on("data", error => {
    
      console.log(error.toString())
    
    })
    

    
    flacError.on("data", error => {
    
      console.log(error.toString())
    
    })
    

    
    //stream.on("error", reject)
    

    
    destination.on("finish", () => {
    
      resolve({
    
        mime: "audio/flac",
    
        size: totalSize,
    
        codec: "flac",
    
        bitdepth: 16,
    
        ext: "flac"
    
      })
    
    })
    

    
    ffmpegOutput.pipe(flacInput)
    
    flacOutput.pipe(destination)
    
  })
    
}

    While this code works, the resulting flac file is not correct. The source audio is of duration 06:14, but the flac file is of duration 06:45:47. Encoding the flac manually without piping ffmpeg to it works fine, but I cannot do that in a server environment where I need to utilize streams.

    Here’s what the flac encoder outputs when transcoding :

  • avcodec/lcldec : Check mthread_inlen instead of cliping

    avcodec/lcldec : Check mthread_inlen instead of cliping

    Clipping was added in 2009 to avoid crashes.
    
The clipped case would produce a 2nd slice with 0 input
    
thus also producing 0 output.
    
Subsequent checks will cause decoder failure unless both
    
slices have the same output length. thus the only way this
    
would not already fail is if the output from both slices
    
was 0 bytes.

  • FFMPEG - Not finding codec parameters

    9 septembre 2024, par Tanner Smith

    I'm trying to convert a sequence of images into a mpeg movie via FFMPEG, although I keep getting an error saying that it could not find the code parameters (Video : mjpeg). A Google search did not bring much up that was useful.

    &#xA;&#xA;

    The images reside in the /tmp directory with names such as img001.jpg and img002.jpg.

    &#xA;&#xA;

    Any ideas ?
