  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • MediaSPIP en mode privé (Intranet)

    17 septembre 2013, par

    À partir de la version 0.3, un canal de MediaSPIP peut devenir privé, bloqué à toute personne non identifiée grâce au plugin "Intranet/extranet".
    Le plugin Intranet/extranet, lorsqu’il est activé, permet de bloquer l’accès au canal à tout visiteur non identifié, l’empêchant d’accéder au contenu en le redirigeant systématiquement vers le formulaire d’identification.

  • What does ffmpeg error "Prediction is not allowed in AAC-LC" mean ?

    21 juin 2014, par user2212461

    When decoding AAC files, ffmpeg returns the error

    "Prediction is not allowed in AAC-LC".

    Does that mean the file is corrupt ? Or that ffmpeg cannot handle AAC-LC files ?

    I tried with different AAC files and get the errors :

    Number of scalefactor bands in group (63) exceeds limit (49).
    

    
TNS filter order 25 is greater than maximum 12.

    So I guess its not my file that is corrupt but ffmpeg can only handle specific AAC formats ? Which would these be ?

  • FFMPEG can not load frei0r plugins via environment path on windows 10

    23 janvier 2018, par sam rolfe

    This works fine on windows 7 - however on windows 10 mo matter what I try FFMPEG can not load the .dll file.

    In debug mode it shows me that it is reading the correct environment path - however it is unable to find the file on that path - its so strange.

    Looking for frei0r effect in ’C :\freior/edgeglow.dll’

    I have tried with all manner of folders, names, slashes, etc - it always returns

    Could not find module ’edgeglow’

    I am wondering of there is some sort of user permissions ? Something is blocking it.

  • ffmpeg aac encoder shows "Input contains (near) NaN/+-Inf"

    26 janvier 2021, par zzzzzz

    here's a question.
When my code goes to ret = avcodec_send_frame(enc_ctx, tmpFrame), sometimes it returns AVERROR(EINVAL). Many people say that the reason is the format of tmpFrame is AV_SAMPLE_FMT_S16, but encoder needs AV_SAMPLE_FMT_FLTP. However, my log shows that tmpFrame->format: 8, tmpFrame->channels: 1, tmpFrame->channel_layout: 4, tmpFrame->sample_rate: 32000, tmpFrame->nb_samples: 1024. Here 8 is the value of AV_SAMPLE_FMT_FLTP.

    


    So what is the reason of this bug ?
