  • Ajouter notes et légendes aux images

    7 février 2011, par

    Pour pouvoir ajouter notes et légendes aux images, la première étape est d’installer le plugin "Légendes".
    Une fois le plugin activé, vous pouvez le configurer dans l’espace de configuration afin de modifier les droits de création / modification et de suppression des notes. Par défaut seuls les administrateurs du site peuvent ajouter des notes aux images.

  • ffmpeg mp3 to mp4 with image compatible with iphone [duplicate]

    3 mai 2016, par neoDev

    This question already has an answer here :

    I need to convert an mp3 to mp4 with image using ffmpeg from my OSX command line.

    I already installed last version of ffmpeg (3.0.2), and tried the following command as described here

    ./ffmpeg -loop 1 -i test.jpg -i test.mp3 -c:a copy -c:v libx264 -shortest test.mp4

    but the result mp4 file is not compatible with my iphone 5

    Now this is what I am trying

    ./ffmpeg -loop 1 -i test.png -i test.mp3 -profile:v baseline -level 3.0 test.mp4

    but I get the error

    Error while opening encoder for output stream #0:0 - maybe incorrect
    parameters such as bit_rate, rate, width or height

  • ffmpeg link errors when building on iPhone 4.3 SDK

    12 septembre 2011, par YuzaKen

    After a rather trying few days, I finally got ffmpeg to compile under Xcode 4 with SDK 4.3. The issue no is a series (39) link errors. They fall into at least two cases : assembly language routines and static arrays defined in header files. My believe is that it is generating C method names for the assembly routines while the .c files containing the reference to the routine is generating a different method name (munging).

  • WMAV2 and FFMPEG on iPhone

    14 avril 2012, par user1333656

    Recently, I try to decode audio files on iPhone by using ffmpeg.
    Most audio formats are decoded properly but WMAV2 isn't.
    The decoded file(raw data) can be imported to sound editor like AUDACITY and it is playable but not clear and different with the original track.
    Is this related to ARM floating point ???

    Someone said VBR WMAV2 could cause this kind of prob.
    Can any body give me any clue for this prob ??
