  • Amélioration de la version de base

    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 (...)

  • Déploiements possibles

    31 janvier 2010, par

    Deux types de déploiements sont envisageable dépendant de deux aspects : La méthode d’installation envisagée (en standalone ou en ferme) ; Le nombre d’encodages journaliers et la fréquentation envisagés ;
    L’encodage de vidéos est un processus lourd consommant énormément de ressources système (CPU et RAM), il est nécessaire de prendre tout cela en considération. Ce système n’est donc possible que sur un ou plusieurs serveurs dédiés.

  • ffmpeg, lower fps with gpu - too many packets buffered

    29 mai 2020, par Alter

    I'm trying to lower the fps for a large set of videos. Unfortunately, I don't have much experience with ffmpeg

    



    This is my current command, which is a hybrid of multiple posts. At this point it's more guess work than anything else

    



    ffmpeg \
  -y -hwaccel_output_format cuda -hwaccel_device 0 -hwaccel cuvid -c:v mpeg2_cuvid \
  -i myinput.mp4 -r 25 -c:v hevc_nvenc-b:v 128K -strict -2 -movflags faststart \ 
  /workspace/videos/24fps_trial2/rat1-control2.mp4 -c:v hevc_nvenc


    



    The gist of it is just that I'm trying to lower fps and use hardware acceleration since my dataset is large

    



    The message I get is

    



    Trailing option(s) found in the command: may be ignored.

  • Attempting to compile FFmpeg 4.2.3 statically for Windows 10 (x86_64), but binaries asks for missing DLLs

    29 mai 2020, par Expectator

    I am using Msys MinGW (x86_64) and pulled a snapshot of the latest major release of FFmpeg off of their website. Here is my ./configure options. I plan to use the binaries on both the computer that I compiled it on, and other Windows computers that I own.

    



    ./configure --enable-libaom --enable-avisynth --enable-chromaprint --enable-libdav1d --enable-libdavs2 --enable-libgme --enable-libmfx --enable-libkvazaar --enable-libmp3lame --enable-libilbc --enable-libvpx --enable-libmodplug --enable-version3 --enable-nonfree --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libvo-amrwbenc --enable-libfdk-aac --enable-libopenh264 --enable-libopenjpeg --enable-nvenc --enable-nvdec --enable-cuda --enable-cuvid --enable-libtwolame --enable-vapoursynth --enable-libwavpack --enable-libx264 --enable-libx265 --enable-libxavs --enable-libxavs2 --enable-gpl --enable-static --disable-shared


    



    Output of configure script (pastebin)

    



    Output of uname -a (in Msys)

    



    MINGW64_NT-10.0-18362 <scrubbed> 3.1.4-340.x86_64 2020-05-22 08:28 UTC x86_64 Msys&#xA;</scrubbed>

    &#xA;&#xA;

    The issue that I'm facing is that despite passing the options --enable-static and --disable-shared, the executables generated still require libchromaprint.dll, libfdk-aac-2.dll, and libgme.dll to run. What I expected was that FFmpeg would execute independently of any DLL files since I passed those options to ./configure.
