  • Anomalie #3697 : Bug svn10000 SPIP 3

    14 février 2016, par MiKaël Navarro

    Cependant je m’étonne que cette erreur là « remplissent les logs du serveur Web », d’autant que l’erreur n’est pas critique.
    Normalement le if ($dir = opendir(...)) n’entre pas dans le if si opendir retourne false. Par contre, oui ça créait une erreur PHP si le dossier n’existait pas, mais qui ne devrait pas perturber il me semble la suite du processus de mise à jour. Je n’ai pas été vérifier cependant.

    Effectivement le if ($dir = opendir(...)) n’entre pas dans le if si opendir retourne false, mais ce n’est pas le code que j’ai dans l’archive spip-3.1.zip (r22707 aujourd’hui en date du 6 janvier), au lieu de ça j’ai seulement (sans le if) : 

    $dir = opendir($base) ;
while (($f = readdir($dir)) !== false) 
...

    De plus je suis d’accord, ce n’est pas une Erreur mais un simple Warning que l’on retrouve dans /var/log/nginx/error.log :

    2016/02/14 12:36:04 [error] 1141#0 : *197 FastCGI sent in stderr : "PHP message : PHP Warning :  opendir(baddir/) : failed to open dir : No such file or directory in /home/mickey/public_html/test-opendir.php on line 2
PHP message : PHP Warning :  readdir() expects parameter 1 to be resource, boolean given in /home/mickey/public_html/test-opendir.php on line 3" while reading response header from upstream, client : 127.0.0.1, server : localhost, request : "GET / mickey/test-opendir.php HTTP/1.1", upstream : "fastcgi ://unix :/var/run/php5-fpm.sock :", host : "localhost"


    Ensuite le test while (($f = readdir($dir)) !== false) rentre dans une boucle infinie et c’est avec ça que j’ai créé un log de plus de 2Go !

    D’après les commit, je vois que c’était déjà corrigé dans la version SVN, mais un test supplémentaire mange pas de pain ça sera plus robuste et évitera l’écriture d’un Warning dans les logs pour rien :)

    En tout cas merci pour votre réactivité.

  • FFmpeg - Concat videos with different time base [duplicate]

    3 mai 2019, par Xys

    This question already has an answer here :

    I’m trying to concat videos with the concat demuxer, but it does not work when using one video ("video2.mp4" below). By does not work, I mean playing the concatenated video on a player will work until the second video part starts (it just cannot read the video anymore). It works with the concat filter though. They are both mp4 videos, so I think it’s because of the time base ? I can concat other videos with the concat demuxer and it works fine (even with different resolutions/bitrate). It only happens when trying to concat "video2.mp4".

    Also, I have a lot of warning/errors like this, probably when ffmpeg starts concatenating the 2nd video :

    [mp4 @ 0x7f847a814800] Non-monotonous DTS in output stream 0:0; previous: 906906, current: 302359; changing to 906907. This may result in incorrect timestamps in the output file.

    What would be the best way to have a minimum concat time ? Do I really need to use the concat filter or can I change the time base of "video1.mp4" if it’s really the problem ?

    Any help would be appreciated, thanks !

  • FFMpeg drawtext not working in my code

    10 juillet 2018, par Dev

    I am trying to overlay a text on existing movie using FFMpeg. Overlaying of an image works perfectly, but failed to drawtext. My code is as below.

    GeneralUtils.checkForPermissionsMAndAbove(RecordVideo.this, true);
    
LoadJNI vk = new LoadJNI();
    
String[] complexCommand = {
    
    "ffmpeg", "-i", FilePath, "-vf",
    
    "drawtext=text='Hello Dev..':"
    
        + "fontsize=24:fontfile=/system/fonts/DroidSans.ttf:box=1:boxcolor=black@0.5:x=w-tw:y=h-th",
    
    FilePath1};
    
vk.run(complexCommand , StorageDIR , getApplicationContext());

    I am getting error as follows
