  • Anomalie #4128 (En cours) : Bug de génération de boucle avec les modèles Spip

    11 avril 2018, par Julien PORIAU

    Dans les modèles personnalisés Spip, les images (boucle documents ou logos) sont mal générées et provoque un bug d’encodage visible dans le front-end lors du passage dans une autre langue (balises multi).
    Nous n’avons pas trouvé où était le souci dans Spip, mais les caractères qui remontent dans le code source, ressemblent aux octets qui composent le fichier binaire d’une image.
    Voir en live ici : http://spip-dev.nidecker.com/probleme-de-langue.html?lang=ca.

    Pour essayer d’isoler cette anomalie, nous avons procédé de la sorte avec l’aide de mon développeur :

    1. Nous sommes reparti d’un SPIP 3.1.7 entièrement neuf (minimal), avec deux modèles Spip, rien d’autre.
    Le bug se reproduit, ce qui exclus un problème lié aux squelettes ou autres plugins.

    Nous n’avons pas réussi a déterminer précisément ce qui génère ce bug, à part que c’est dans un contexte où on appelle une langue pas définie dans le multi.
    En fonction du contenu de l’article, du nombre de modèles dans l’article, en fonction des boucles dans les inclure, le bug n’arrive pas au même endroit...

    Le problème vient de la génération des logos ou documents : si on supprime les balises #LOGO_* ou si on renomme IMG en IMG_, plus d’erreur.
    Même sans traitements, avec juste [(#LOGO_*)], rien à faire.

    2. Nous avons pensé que c’était peut être une image au mauvais format : On a alors tenté de passer ImageOptim sur tout le répertoire /IMG, redimensionné tous les logos en vignettes png de 320x240, rien à faire...

    3. On a fini par passer ce site de test en 3.2, pas mieux.

    4. Nous avons épluché les caches générés dans /tmp/cache et /tmp/cache/skel, tout paraît normal de ce côté là..

    5. On a ensuite un peu avancé en enlevant dans mes_options.php la variable $GLOBALS['forcer_lang'] = true".
    Sur la version minimal, plus de bug. Mais sur le site de production, le problème réside toujours.
    Mais en faisant des tests avec et sans (et en supprimant bien /tmp/cache/ à chaque fois), ça se confirme pour la version minimal.

    6. A partir d’une copie de la version production, nous avons désactivé tout les plugins, passer ImageOptim sur /IMG et rien a faire.. Impossible de déterminé d’où vient le problème :(

    7. Nous avons essayé d’écrire comme ceci : [<img src="http://core.spip.org/projects/spip/(#LOGO_MOT|image_reduire{50,*}|extraire_attribut{src})" alt="" style='max-width: 300px; max-height: 300px' />]
    Cela fonctionne sur la version minimal mais pas sur la version production.

    8. Dans la version minimal, j’ai encore récemment testé une dernière chose. J’ai supprimé les documents non sollicités sur ma page de teste (spip.php ?article1441&lang=ca).
    Avec la requête SQL suivante : DELETE FROM jones_documents WHERE id_document NOT IN (1948,1949,2534,2535,630,631,1783,1784,1785,1786,1787,1788,1781,1782)
    Le bug n’apparait plus..

    Je sèche..

    Vous trouverez ici en téléchargement une archive de la version minimal (Spip 3.1.7) : https://www.dropbox.com/s/dek0zg7jafl8uxe/jones.zip?dl=0] ( 20mo)
    Pour reproduire le bug, il suffit de passer la variable "&lang=ca" dans l’article 1441 (localhost/spip.php ?article1441&lang=ca).

    Je donne volontiers un accès à la version production si besoin.

  • ffmpeg command for faster encoding at a decent bitrate with smaller file size

    14 septembre 2016, par Blair Holmes

    I’m currently using an implementation of ffmpeg on my android app. I’m allowing users to take short videos within my app and then when they upload them to the server, I’m crunching them down with ffmpeg to decrease file size so they’re not passing huge amounts of data over the wire.

    the problem is, it’s taking forever to encode the videos on the android device. These videos usually aren’t longer than 45 seconds and can take 20 minutes to encode. I’ve done some playing around with different switches / parameters on the ffmpeg command line and I now have it at a more comfortable time, but the file sizes are significantly bigger. I’m just not sure what codec I should use (fastest encoding but with decent quality output), how ffmpeg handles changing size (aspect ratio) in terms of speed of encoding etc.

    Here are the two commands I’ve been using. This first one outputs the file size / quality that I want, but it just takes way too long to encode, not to mention it makes my device get really hot while it’s encoding for so long :

    ffmpeg -i input.mp4 -b:v 1024k -c:a copy -vf scale=960:540 output.mp4

    I’ve tweaked the bitrate some on that as well as changed the scale to a smaller size, but I don’t want to have to make the videos really small (in terms of scale) to accomplish a faster encoding. this second command goes a lot faster but makes the file size significantly bigger :

    ffmpeg -i input.mp4 -vcodec libx264 -preset fast -c:a copy -s 960x540 output.mp4

    I’d like to find a happy medium (smaller file size but faster encoding) keeping the video scale size close to the original. ffmpeg just has so many different parameters / switches that it’s difficult to wrap my head around what I should be doing.

    EDIT : adding ffmpeg output.

    ffmpeg -i input.mp4 -vcodec libx264 -crf 30 -preset veryfast -c:a copy -s 960x540 output.mp4

    I'm currently using an implementation of ffmpeg on my android app. I'm allowing users to take short videos within my app and then when they upload them to the server, I'm crunching them down with ffmpeg to decrease file size so they're not passing huge amounts of data over the wire.

    &#xA;&#xA;

    the problem is, it's taking forever to encode the videos on the android device. These videos usually aren't longer than 45 seconds and can take 20 minutes to encode. I've done some playing around with different switches / parameters on the ffmpeg command line and I now have it at a more comfortable time, but the file sizes are significantly bigger. I'm just not sure what codec I should use (fastest encoding but with decent quality output), how ffmpeg handles changing size (aspect ratio) in terms of speed of encoding etc.

    &#xA;&#xA;

    Here are the two commands I've been using. This first one outputs the file size / quality that I want, but it just takes way too long to encode, not to mention it makes my device get really hot while it's encoding for so long :

    &#xA;&#xA;

    ffmpeg -i input.mp4 -b:v 1024k -c:a copy -vf scale=960:540 output.mp4&#xA;

    &#xA;&#xA;

    I've tweaked the bitrate some on that as well as changed the scale to a smaller size, but I don't want to have to make the videos really small (in terms of scale) to accomplish a faster encoding. this second command goes a lot faster but makes the file size significantly bigger :

    &#xA;&#xA;

    ffmpeg -i input.mp4 -vcodec libx264 -preset fast -c:a copy -s 960x540 output.mp4&#xA;

    &#xA;&#xA;

    I'd like to find a happy medium (smaller file size but faster encoding) keeping the video scale size close to the original. ffmpeg just has so many different parameters / switches that it's difficult to wrap my head around what I should be doing.

    &#xA;&#xA;

    EDIT : adding ffmpeg output.

    &#xA;&#xA;

    ffmpeg -i input.mp4 -vcodec libx264 -crf 30 -preset veryfast -c:a copy -s 960x540 output.mp4
