  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • ffmpeg exit code 429496724 when opening file with {} in name

    16 février, par Holly Wilson

    I'm trying to write a program that will read the names of files in a directory, and parse them for info which it will then write into that file's metadata (seems pointless, I know, but it's more of a trial run for a larger project. If I can figure this out, then I'll be ready to move on to what I actually want to do).
All of my filenames are formatted :

    


    Title, Article* - Subtitle* Cut* [Year]
*if present

    


    The four test videos I'm using are titled :

    


    Test Video 1 [2000]

    


    Test Video 2, A [2000]

    


    Test Video 3 Test Cut [2000]

    


    Test Video 4 - The Testening [2000]

    


    The code seems to be working fine on videos 1, 2, & 4 ; but video 3 is causing me a lot of headache.

    I've tried so many different solutions in the sanitizeFilePath function. Escaping the {} characters (as included below), escaping all non-alphanumeric characters, putting the filepath in quotes, etc. VSCode's CoPilot is just pulling me round in circles, suggesting solutions I've already tried.

    


  • How to combine multiple video blobs in js without gap ?

    5 septembre 2021, par Pouria Moosavi

    I have an array of urls. I download them with fetch and then get blob from each response with await res.blob(). I need to concat all these blobs together to make a full video out of it, I tried to push each blob into an array and make a file new File(blobArray, "test") but the result has a gap between each blob.

    


    I've tried to save each blob as a separate file and concat them with ffmpeg -f concat -safe 0 -i text -c copy out3.mp4 and the result was perfect. So I know that my blobs are correct and the problem is how I am combining them together.

    


    This is my full code :

    Unfortunately links will expire soon but I think it is obvious what I am trying to do.

    


    So Is there any way to cancat blobs in JS and create the entire video smoothly like the ffmpeg does ?

    


    Thanks in advance.

    


  • ffmpeg : error reading header pipe:0 : Invalid argument

    25 février 2021, par Дмитрий Бондаренко

    I need microservice (converter audio using streams), but have problem with ffmpeg

    


    my test ffmpeg

    


    package codec

import (
    "bytes"
    "os"
    "os/exec"
    "testing"
)

func Test1(t *testing.T) {
    in, err := os.Open("/mp4-mp3/src.m4a")
    if err != nil {
        t.Fatal(err.Error())
    }
    out, err := os.OpenFile("/mp4-mp3/out.mp3", os.O_RDWR|os.O_CREATE, 0666)
    if err != nil {
        t.Fatal(err.Error())
    }
    cmd := exec.Command(
        "ffmpeg",
        "-f", "m4a",
        "-i", "pipe:0",
        "-f", "mp3",
        "pipe:1")

    cmd.Stdin = in
    cmd.Stdout = out
    stderr := &bytes.Buffer{}
    cmd.Stderr = stderr
    if err := cmd.Run(); err != nil {
        t.Logf(stderr.String())
        t.Fatal(err.Error())
    }

}



    


    At the exit, I have the error invalid argument
i tried different options but the problem didn't change
