  • 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.

  • Le profil des utilisateurs

    12 avril 2011, par

    Chaque utilisateur dispose d’une page de profil lui permettant de modifier ses informations personnelle. Dans le menu de haut de page par défaut, un élément de menu est automatiquement créé à l’initialisation de MediaSPIP, visible uniquement si le visiteur est identifié sur le site.

  • mp4 created by ffmpeg will not play with IPython.display.Video

    19 novembre 2020, par Austin

    I'm creating a mp4 video from jpegs with ffmpeg, using the following command :

    


    ffmpeg -y -threads 0 -f image2 -i jpegs/%05d.jpg -framerate 10 video.mp4

    


    The resulting video will play fine with VLC, but will not play in a Jupyter notebook via :

    


    from IPython.display import Video
Video('video.mp4')


    


    This notebook video functionality has worked for me in the past, so I assume there's something about the codec/mime type that the Video function can't resolve ?

    


    


    Requested update

    


    New command I've tried :

    


    ffmpeg -y -framerate 10 -i jpegs/%05d.jpg -vf format=yuv420p -movflags +faststart video.mp4

    


    Video still plays fine in VLC and still does not play in Jupyter. I've looked at the duplicates this is marked as and it does not actually seem to be the same issue..

    


    Here's the output (I've removed the framerate and threads flags to simplify) :

  • FFmpeg installation on Raspberry Pi Zero W : Undefined references to __atomic

    3 février 2021, par MisterGray

    I'm trying to install ffmpeg on my Raspberry Pi Zero W, but I get several error messages.

    &#xA;

    OS : Raspberry Pi OS (32-bit) Lite (May 2020)

    &#xA;

    I have executed the following commands :

    &#xA;

    sudo apt update&#xA;sudo apt full-upgrade&#xA;sudo apt install git&#xA;git clone https://github.com/FFmpeg/FFmpeg.git&#xA;cd FFmpeg&#xA;./configure --arch=armel --target-os=linux --enable-gpl --enable-omx --enable-omx-rpi --enable-nonfree&#xA;make -j2&#xA;sudo make install&#xA;

    &#xA;

    Output of last command :

    &#xA;

    ...&#xA;LD      ffmpeg_g&#xA;/usr/bin/ld: libavformat/libavformat.a(fifo.o): in function `fifo_init&#x27;:&#xA;/home/pi/FFmpeg/libavformat/fifo.c:519: undefined reference to `__atomic_store_8&#x27;&#xA;/usr/bin/ld: libavformat/libavformat.a(fifo.o): in function `fifo_write_trailer&#x27;:&#xA;/home/pi/FFmpeg/libavformat/fifo.c:624: undefined reference to `__atomic_fetch_add_8&#x27;&#xA;/usr/bin/ld: /home/pi/FFmpeg/libavformat/fifo.c:631: undefined reference to `__atomic_store_8&#x27;&#xA;/usr/bin/ld: libavformat/libavformat.a(fifo.o): in function `fifo_thread_write_packet&#x27;:&#xA;/home/pi/FFmpeg/libavformat/fifo.c:188: undefined reference to `__atomic_fetch_sub_8&#x27;&#xA;/usr/bin/ld: libavformat/libavformat.a(fifo.o): in function `fifo_consumer_thread&#x27;:&#xA;/home/pi/FFmpeg/libavformat/fifo.c:457: undefined reference to `__atomic_load_8&#x27;&#xA;/usr/bin/ld: libavformat/libavformat.a(fifo.o): in function `fifo_write_packet&#x27;:&#xA;/home/pi/FFmpeg/libavformat/fifo.c:597: undefined reference to `__atomic_fetch_add_8&#x27;&#xA;collect2: error: ld returned 1 exit status&#xA;make: *** [Makefile:114: ffmpeg_g] Error 1&#xA;

    &#xA;

    Maybe another package is missing ? Do I have to change anything in the config ?
