  • ffmpeg : remove access to private FILE struct members on Windows

    ffmpeg : remove access to private FILE struct members on Windows

    The FILE struct is opaque in MSVC 2015, and the members of this struct
    
were never meant to be accessed in any case.
    

    No conditions are known where this check was needed to get characters
    
from stdin.

  • Documentation #3374 (Nouveau) : "PHP Warning : Cannot modify header information" récurrentes

    14 janvier 2015, par Eric Camus

    Sur une machine Windows + IIS 6, avec des SPIP 3.0.17 + Sarka 3.2.28.

    On subit à longueur de journée des erreurs :
    [13-Jan-2015 10:29:07 Europe/Paris] PHP Warning:  Cannot modify header information - headers already sent by (output started at D:\wwwwww\yyyyyyy\ecrire\public.php:154) in D:\ wwwwww\yyyyyyy \ecrire\inc\headers.php on line 152

    Après une analyse du code et des essais en production, j’ai identifié que ces erreurs proviennent toutes (quel que soit le site SPIP sur les 180 actuellement en production) de l’écriture du fichier " tmp/cache/chemin.txt" qui termine le calcul de la page. Ci-dessous un debug_backtrace() :

    Cette analyse montre que ces erreurs passent toutes par l’appel de la fonction "raler_fichier" dans " ecrire_fichier" du fichier "flock.php" :

        if (!$ignorer_echec) 
        include_spip(’inc/autoriser’) ;
        if (autoriser(’chargerftp’))
            raler_fichier($fichier) ;
        spip_unlink($fichier) ;

    Maintenant les questions :

    - Pourquoi seuls les administrateurs affichent cette erreur qui en plus arrête le processus par un "exit" dans "raler_fichier", donc les codes suivant ne sont pas exécuter (suppression et log SPIP) ? Sans compter que l’on ne voit rien car la plupart du temps elle arrive dans un fichier de CSS !!!
    - Pourquoi supprimer un fichier qui n’est pas obligatoirement en erreur car c’est probablement un problème de LOCK (deux processus en même temps) ?
    - Peut-on désactivé cette portion de code sans risque de problème ?

    Pour la part, je prends sur moi de supprimer cette portion de code.

  • Recording RTP VP8 packets with FFMPEG with named pipe

    6 août 2015, par Filipe Apolinário

    I’m developing a WebRTC video session recorder, in a gateway developed in C++, where I only have access to individual RTP packets.

    When a session starts, I create two threads one that initializes a named pipe and an other that starts FFMPEG to fetch data from that pipe and store it in a matroska file, with the command :

    ffmpeg -i \\.\pipe\screenRec -f matroska D:\djhfifj.mkv

    Whenever I receive an RTP packet I send it through the pipe to FFMPEG. Although all communication is working fine, FFMPEG does not seem to be recognizing the RTP packet :

    Is it possible to make FFMPEG understand that the packet sent is RTP with VP8 ?
