  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • Evolution #3610 : Avoir les répertoires plugins/auto par défaut dans la dist

    30 janvier 2018, par RastaPopoulos ♥

    Non pour la création depuis PHP à mon avis, puisque pour création il faut qu’il y ait les droits d’écriture de PHP sur le dossier parent, or "plugins" ne fait pas partie des dossiers sur lesquels la personne qui installe doit mettre des droits d’écriture obligatoire, et ça ne doit pas le devenir d’après moi.

    Seul plugins/auto doit avoir les droits d’écriture normalement. Donc le fournir d’office à l’installation oui pourquoi pas, et aussi l’ajouter à la liste des dossiers qui doivent être "écrivables" lorsqu’il existe (avec tmp, config, local, IMG) afin que lors de l’installation ça le signale si ce n’est pas le cas.

  • ffmpeg Error while filtering : Cannot allocate memory

    7 juillet 2017, par Andres MERE

    My workstation seems to have plenty of memory (and everything). When I am trying to run ffmpeg as follows :

    /usr/local/bin/ffmpeg \
    
    -loglevel debug \
    
    -i "A066C002_170619NU_CANON.mov" \
    
    -filter_complex "[0:0] [0:2] amerge, aformat=sample_fmts=s16:channel_layouts=stereo [a]" \
    
    -map "[a]" \
    
    -map 0:5 \
    
    -c:a libfdk_aac \
    
    -vbr 3 \
    
    -vcodec libx264 \
    
    -profile:v baseline \
    
    -level 3.0 \
    
    -vf scale=1280:720 \
    
    -pix_fmt yuv420p \
    
    -crf 20 \
    
    -metadata title="Test movie" \
    
    -movflags +faststart \
    
    -y \
    
    "A066C002_170619NU_CANON.mp4"

    It fails with "Error while filtering : Cannot allocate memory".

  • Rsync a video stream continously and watch it

    13 juin 2017, par Ural

    I am recording a cam on a remote machine in my office. I use ffmpeg for that, and writing to mpegts file.
    I want to copy that stream locally, to have a fresh copy, and watch it simultaneously.
    I don’t know options for rsync to grab a changing (appending) file, so I am using loop for it, and it is very slow.

    while true; do rsync -avz --progress --partial --append remote:~/myvideo.mp4 ~/; done

    For watching, I tried :

    mkfifo /tmp/fifo
    
tail -f ~/myvideo.mp4 > /tmp/fifo
    
mplayer /tmp/fifo

    But because rsync is stopping every 5 sec, it is working unstable.

    How to record and stream a remote cam continuously, and use only one network stream for that ?
