  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

  • Les tâches Cron régulières de la ferme

    1er décembre 2010, par

    La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
    Le super Cron (gestion_mutu_super_cron)
    Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...)

  • Manipulating one video into multi outputs with FFmpeg results in no audio in the last output

    27 octobre 2015, par my name is

    Using FFmpeg, I’m trying to do some filtering operations on one input video to scale it (out1), scale and trim it (out2).
    This is the command I’m using :

    ffmpeg -y \
    
-i "Robotica_1080.mkv" \
    
-filter_complex "[0:v]split=2[v1][v2]; \
    
[v1]scale=640:360,setpts=PTS-STARTPTS[vout1]; \
    
[v2]trim=10:15,scale=640:360,setpts=PTS-STARTPTS[vout2]; \
    
[0:a]asplit=2[a1][a2]; \
    
[a1]anull,asetpts=PTS-STARTPTS[aout1]; \
    
[a2]atrim=10:15,asetpts=PTS-STARTPTS[aout2]; \
    
[vout1][aout1]concat=n=1:v=1:a=1[out1]; \
    
[vout2][aout2]concat=n=1:v=1:a=1[out2]" \
    
-map "[out1]" "1.mp4" \
    
-map "[out2]" "2.mp4"

    1.mp4 is ok while 2.mp4 lasts 5 seconds as expected but without audio at all (the QuickTime inspector doesn’t write the audio codec)

    I tried to remove the trim/atrim filters, so the filter_complex parameter looked like this :

    -filter_complex "[0:v]split=2[v1][v2]; \
    
[v1]scale=640:360[vout1]; \
    
[v2]scale=640:360[vout2]; \
    
[0:a]asplit=2[a1][a2]; \
    
[a1]anull[aout1]; \
    
[a2]anull[aout2]; \
    
[vout1][aout1]concat=n=1:v=1:a=1[out1]; \
    
[vout2][aout2]concat=n=1:v=1:a=1[out2]" \

    but still no audio on 2.mp4

    Can anyone give me a hint ?

    —EDIT—
    This is the output from first ffmpeg command :

  • ffmpeg-mp4box-mpeg dash plays only few segments

    30 octobre 2015, par Idris

    Need help in debugging the segment dash files

    The input was an MP4 with these details. This was recorded from a video camera, the output from the camera was mkv and we converted into MP4 after editing the audio via adobe

    • Size : 7.51 GB Frame rate : 25 frames/ second
    • Data rate : 25326kbps
    • Total bitrate : 25525kbps

    Converted this to another mp4 with this command

    ffmpeg -i "input.mp4" -s 1280x720 -c:v libx264 -b:v 750k -bf 2 -g 75 -sc_threshold 0 -an video_1280x720_750k.mp4
    

    
ffmpeg -i "input.mp4"  -c:a aac -strict experimental -b:a 96k -ar 32000 -vn audio_96k.mp4

    The output video has

    • fps : 25
    • Data rate : 761kbps
    • bitrate : 761kbps

    Then, created the segmented dash through MP4Box

    MP4Box -dash 10000 -frag 10000 -rap -segment-name video_0_1280000\segment_ video_1280x720_750k.mp4
    

    
MP4Box -dash 3000 -frag 10000 -rap -segment-name audio_0_96000\segment_ audio_96k.mp4

    The MPD generated was validated online and its perfect

    Played the video through dashjs.. I believe it just plays the initial segment and errors out as MEDIA_ERR_DECODE..MEDIA_ERR_SRC_NOT_SUPPORTED.. or some message which says start not found..

    Through chrome debugging I see that atleast 4 segments are correctly loading.. I am not sure whats going on..

    Any help in debugging the issue is really appreciated. I really can’t understand if this is a problem with the file or ffmpeg or mp4box or chrome.

    Output from chrome debugging tool

  • 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.
