  • 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.

  • Yet another ffmpeg/libx264 issue

    26 décembre 2013, par kerim yucel

    My current situation is ; ffmpeg and libx264 has been compiled for Android, as shared and static libraries respectively. Since I have libx264.a and libffmpeg.so with me, only thing that remains is to link them and obtain a ffmpeg library that would allow me to proceed with my application. However, some questions remain unanswered. I am using Ubuntu with a virtual machine under Windows 7. I am using x264's last version, ffmpeg 0.10.4 release and NDK 7.

    I have tried to adjust flags (extracf and extrald) in order to include libx264 to ffmpeg compilation process as well, however I keep failing. Below you may find my build script for ffmpeg and the errors I have encountered.

    I have x264 installed in my directory /home/mehmet/x264 and I also check whereis x264.a, it shows me as /usr/local/lib. I have tried changing the path $x264 to point out to home/mehmet/x264 folder, but I get the same error.

    Lastly, if I enable both extracf and extrald flags ( both commented ones and the used ones) . I get the same error mentioned above. I am afraid I am doing a simple typo here, but can`t see it and it is driving me crazy. Thanks a lot for your help.

  • ffmpeg merge video and audio + fade out

    1er mai 2016, par jacky brown

    I have one video file and one audio file.
    I want to merge them together that the final output video will be in the length of the video and will contain the audio in the background.

    i did :

    ffmpeg -i output.avi -i bgmusic.mp3 -filter_complex " [1:0] apad " -shortest out.avi

    but the background audio is cut in the end of the final merge movie.
    i want it to fade out nicely.

    how can i do it ??
