Amélioration de la version de base

13 septembre 2013

Jolie sélection multiple
Le plugin Chosen permet d’améliorer l’ergonomie des champs de sélection multiple. Voir les deux images suivantes pour comparer.
Il suffit pour cela d’activer le plugin Chosen (Configuration générale du site > Gestion des plugins), puis de configurer le plugin (Les squelettes > Chosen) en activant l’utilisation de Chosen dans le site public et en spécifiant les éléments de formulaires à améliorer, par exemple select[multiple] pour les listes à sélection multiple (...)
Les tâches Cron régulières de la ferme

1er décembre 2010, par kent1

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 (...)
Menus personnalisés

14 novembre 2010, par kent1

MediaSPIP utilise le plugin Menus pour gérer plusieurs menus configurables pour la navigation.
Cela permet de laisser aux administrateurs de canaux la possibilité de configurer finement ces menus.
Menus créés à l’initialisation du site
Par défaut trois menus sont créés automatiquement à l’initialisation du site : Le menu principal ; Identifiant : barrenav ; Ce menu s’insère en général en haut de la page après le bloc d’entête, son identifiant le rend compatible avec les squelettes basés sur Zpip ; (...)

CMTimeGetSeconds doesn't get the right video duration

26 février 2015, par JLCastillo

some users don’t get the right duration of videos they capture with their own device. The funny thing is others do actually see it right, using the same device models and OS version. Anyway, we observed it in a iPhone 5c 7.1.2 and an iPhone 5s 8.1.3.

This code works for most users, but not all :

ALAssetRepresentation *representation = [mediaObject.asset defaultRepresentation];

NSURL *url = [representation url];

NSDictionary *options = @{ AVURLAssetPreferPreciseDurationAndTimingKey : @YES };

AVAsset *avAsset = [AVURLAsset URLAssetWithURL:url options:options];

videoDurationTime = CMTimeGetSeconds(avAsset.duration);

I asked them to send the input videos, and this is the output from "ffmpeg -i"

Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'bug_duration1.MOV':

The video is detected with a duration of several minutes. Did anybody face this problem before ?

Thanks in advance.

ffmpeg seek calculating wrong byte range ?

17 décembre 2015, par user4455

I’m running into an issue while trying to extract thumbnails from a movie file at a specific timestamp. Generally I’ve had no issues with this, but I’ve come across a set of movie files that are getting an error about the byte range requested (416 Requested Range Not Satisfiable).

The odd thing is that the server is correctly returning the content length in the partial content request, yet when it requests the movie file it requests a length that exceeds that.

This is a bit over my head, so I’m not sure what could be happening here. Any insight would be great.

The Command :

/usr/bin/ffmpeg -y -ss 1400 -i 'https://s3-us-west-2.amazonaws.com/my-bucket/mymoviefile.mp4' -qscale:v 2 -f image2 -vframes 1 -filter:v 'scale=192:108' -loglevel debug /data/www/storage/test.jpg 2>&amp;1

The Error :

[https @ 0x22e1e00] header='HTTP/1.1 416 Requested Range Not Satisfiable'

[https @ 0x22e1e00] http_code=416

Cannot play this video when converting format to .mp4

22 décembre 2015, par user3653474

I am converting video to .mp4 format, but when i convert video using ffmpeg using the following command :

exec('D:\wamp\bin\ffmpeg.exe -y -i D:/wamp/www/upload_google_drive/output.flv -c:v libx264 -crf 19 -preset slow -c:a aac -strict experimental -b:a 192k -ac 2 D:/wamp/www/upload_google_drive/w3.mp4 2>&amp;1',$output);

in some of the devices it does not run. The message which appears is

Cannot play this video.

Please help to sort out my issue.
