Menus personnalisés
14 novembre 2010, parMediaSPIP 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 ; (...) -
Le plugin : Podcasts.
14 juillet 2010, parLe problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;
Types de fichiers supportés dans les flux
Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 (...) -
Mise à disposition des fichiers
14 avril 2011, parPar défaut, lors de son initialisation, MediaSPIP ne permet pas aux visiteurs de télécharger les fichiers qu’ils soient originaux ou le résultat de leur transformation ou encodage. Il permet uniquement de les visualiser.
Cependant, il est possible et facile d’autoriser les visiteurs à avoir accès à ces documents et ce sous différentes formes.
Tout cela se passe dans la page de configuration du squelette. Il vous faut aller dans l’espace d’administration du canal, et choisir dans la navigation (...)

Ffmpeg : how to keep orientation when trimming video file ?
7 mars 2013, par AlexI have a video file which I capture from my Android program and save as an mp4 video.
In this my Android program I use
setOrientationHint(90)call to indicate to a videoplayer that my camera has been rotated 90 degrees.
I'm not really sure what
setOrientationHint(90)does but with it I can see the file properly oriented when it plays in the video player. If not, then a video player orients my file incorrectly.Now I trim this file using FFMPEG command (here
in.mp4, out.mp4, 1000and2000are just for example)ffmpeg -i in.mp4 -ss 1000 -t 2000 -vcodec copy -acodecHowever, the resulting file is again wrongly oriented in the player.
I wonder what should I do to keep the orientation hint in the trimmed video file ?

8 février 2016, par Dmitriy GerashenkoWin 7 x64.
When I watch this link in VLC player all is fine :
rtsp ://184.72.239.149/vod/mp4:BigBuckBunny_175k.mov
When I try to capture link to file and to display :
- There is video without sound on display.
- Created file is not playable.
Command :
vlc.exe -vvv "rtsp://184.72.239.149/vod/mp4:BigBuckBunny_175k.mov" --sout="#transcode{venc=ffmpeg,vcodec=mp4v,vfilter=canvas{width=800,height=600},aenc=ffmpeg{strict=-2},acodec=mp4a}:duplicate{dst=display,dst=standard{access=file,mux=mp4,dst=video.mp4}"There are some errors in log, for example :
