  • Initialisation de MediaSPIP (préconfiguration)

    20 février 2010, par

    Lors de l’installation de MediaSPIP, celui-ci est préconfiguré pour les usages les plus fréquents.
    Cette préconfiguration est réalisée par un plugin activé par défaut et non désactivable appelé MediaSPIP Init.
    Ce plugin sert à préconfigurer de manière correcte chaque instance de MediaSPIP. Il doit donc être placé dans le dossier plugins-dist/ du site ou de la ferme pour être installé par défaut avant de pouvoir utiliser le site.
    Dans un premier temps il active ou désactive des options de SPIP qui ne le (...)

  • 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.

  • Can I know which byte range to read from a remote mp4 file for FFMpeg to decode a keyframe ?

    12 octobre 2023, par db9117

    I need to decode a of keyframe of a video file (mp4, h264 encoded). I know the timestamp of the keyframe I want to extract/decode. I want to minimize amount of data being read in memory. For this, I need to know beforehand exactly the minimal byte range I would require that encompasses this keyframe. How do I know what is the minimal byte range in the whole mp4 byte stream I need to read in order to be able to decode the keyframe ?

    &#xA;

    I currently find the appropriate keyframe in the index_entries contained in the header. I get its byte position (pos attribute) and timestamp (timestamp attribute). I calculate the range as follows :

    &#xA;

    startBytes : minimum of :

    &#xA;

      &#xA;
    1. the pos of the keyframe
    2. &#xA;

    3. the pos of the nearest index entry in the audio stream happening at or before the keyframe's timestamp.
    4. &#xA;

    &#xA;

    This way when it's decoding the frame, if it also needs the audio content for demuxing, it would have it.

    &#xA;

    endBytes : maximum of :

    &#xA;

      &#xA;
    1. the pos of the next frame in the video stream's index, after the keyframe
    2. &#xA;

    3. the pos of the next frame in the audio stream's index after the timestamp of the wished keyframe.
    4. &#xA;

    &#xA;

    This way I know that I have everything up until the next frame in the index, which theoretically should be enough to decode the keyframe only.

    &#xA;

    I then read the appropriate byte range.

    &#xA;

    When I try to decode the frame, I run in a loop until I succeed :

    &#xA;

      &#xA;
    • avcodec_read_frame
    • &#xA;

    • avcodec_send_packet
    • &#xA;

    • avcodec_receive_frame
    • &#xA;

    &#xA;

    I ignore AVERROR(EAGAIN) errors.

    &#xA;

    avcodec_receive_frame fails multiple times with error AVERROR(EAGAIN) which I ignore, until it fails saying that the memory it wants to read isn't available (wants to read after endBytes). I explicitly tell it to fail if it wants to read more than it has already read.

    &#xA;

    Note : for other keyframes at other positions in other videos, it sometimes succeeds (probably because the range is big enough by chance), but it fails more often than not.

    &#xA;

    My question is : Why is the end of the range not enough to be able to decode only the one keyframe ? Is there any way to more precisely calculate the exact range in bytes I would need in order to decode a particular keyframe ?

    &#xA;

  • MediaCodec hardware decoder much slower with different server configuration ?

    19 octobre 2013, par mathieujofis

    I've been using the Android MediaCodec in order to (hardware) decode H.264 frames on my Galaxy S4 coming from a Live 555 RTSP live (real-time) stream. After changing my Live 555 server configuration from using ffmpeg (with x264) to encode frames, to using strictly x264 to encode frames, the time to decode frames with MediaCodec takes much longer. Basically, MediaCodec can't keep up with the stream, and displays the video in slow motion, getting slower and slower as time goes on. Going back to ffmpeg isn't a solution for me, because I need the ability to encode into discrete NAL units, rather than a whole frame like ffmpeg does.

    I was wondering if this was either : A) An issue with the way my server is encoding NAL units, or B) An issue with my Android client, specifically the way it is receiving and decoding NAL units.

    My encoding configuration with x264 is :

    x264_param_default_preset(&amp;param,"ultrafast", "zerolatency:fastdecode");
    param.i_threads = 1;
    param.i_bframe = 1;
    param.i_width = image_width;
    param.i_height = image_height;
    param.i_fps_num = 60;
    param.i_fps_den = 1;
    param.i_keyint_max = 10;

    param.rc.i_rc_method = X264_RC_ABR;
    param.rc.i.bitrate = 6000;
    param.i_sps_id = 7;
    param.b_repeat_headers = 1;
    param.b_annexb = 0;

    My Android MediaCodec client is set up as follows :

    I receive each individual NAL unit on a separate Live 555 RTSP client thread. Each NAL is put into a queue along with its size and presentation time. A separate decoder thread grabs NALs from this queue, and if there are none available, waits until there are.

    Some notes :

    What I generally see happen is the queue starts filling up with NALs, instead of staying close to empty. So, I know that the decoder thread is not working fast enough. I don't think this is an inherent problem with decoding on an Android phone (for example, processing limitations) because it does the same thing for very low bitrates— also again, it DID work when I was using ffmpeg to encode. If I omit certain NAL units, the decoder can start to keep up. Since I'm using Cyanogenmod 10.1, bumping up the minimum CPU frequency helps, too.

    Edit :

    Here is a log of the Android client, as well as a log highlighting the garbage collector specifically—
