  • 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.

  • ffmpeg hwmap SW decoded frame to OpenCL and hwmap back to h264 for SW encode

    3 novembre 2019, par Oleksandr Kyrpa

    I trying speed up process and avoid copy frames between GPU and CPU. But got error : "Segmentation fault : 11", so may be I’m doing something wrong ?

    My full ffmpeg command and log here :

    ./ffmpeg -i ../720.mp4 -init_hw_device opencl=ocl:0.1 -filter_hw_device ocl  -filter_complex "hwmap,avgblur_opencl=30,hwmap"  -c:v h264 -an -t 10 -y ../out_blur.mp4 -loglevel debug

    Output :

  • Evolution #4396 (Nouveau) : utiliser SPIP avec MySQL 8.0

    25 octobre 2019, par Nicolas Krebs -

    La branche 8.0 de MySQL est sortie en 2018. À mon avis, il serait bon que SPIP puisse fonctionner avec, et que la compatibilité soit indiquée dans https://www.spip.net/fr_article4351.html .

    The command produces a MP4 file. The file takes a long time to open and then it takes several more minutes for a frame to appear. The converted file is also missing audio.

    Does anyone have an idea about the slow loading time and missing audio ?
