  • La sauvegarde automatique de canaux SPIP

    1er avril 2010, par

    Dans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
    Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

  • creating Homebrew symlink for beginners

    19 mars 2021, par Platypore

    I am having issues installing the Rust dependency while trying to install ffmpeg through Homebrew on macOS 10.3.6. Terminal just eventually hangs, as is well known in other posts about the topic for Sierra (and I guess High Sierra too). I have installed Rust subsequently using the following command from their website :

    


    curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh


    


    It seems I need to now create a symlink between the Rust directory created by the above command and Homebrew so that Homebrew can recognize the dependency as being installed, but I am absolutely not versed in how to do this ; my terminal knowledge is limited to very simple basics and plugging in code from other answers has not worked. I don't have the knowledge to discern what is a generic path meant to be replaced by specific locations and what is meant to be left as is when it comes to terminology such as prefix and $PATH.

    


    I believe the following are the paths I need to symlink to continue on with my installation of ffmpeg, but I honestly have no idea.

    


    /Users/usr/.rustup/toolchains/stable-x86_64-apple-darwin/bin/rustc 
/Users/usr/.rustup/toolchains/stable-x86_64-apple-darwin/bin/cargo


    


    Could anyone please help and explain step-by-step how to go about doing this ?

    


  • lavf/movenc : write track title metadata for mov files

    lavf/movenc : write track title metadata for mov files

    Track title (atom 'name') is a well defined user data atom for mov files. Existing code (for mp4) only writes title metadata if present.

  • FFMPEG rgb image from named pipe in to h256 rawvideo out to named pipe out

    12 octobre 2018, par Evren Bingøl

    I am forking an ffmpeg and piping in rgb0 images and read hvec rawvideo (h256 frames) out.

    This is the command I am using

    ffmpeg -y -video_size 176x144 -f rawvideo -pix_fmt rgb0 -i 
    
\\\\.\\pipe\\my_pipe  -c:v libx265   -f rawvideo  \\\\.\\pipe\\my_pipe_out

    The issue is I never hear anything in ffmpeg when I try to read the pipe, so ffmpeg is not spitting anything out.

    When piping data into ffmpeg, I would assume that ffmpeg knows by the format parameter that it is rgb, and by the dimensions parameter, its size and calculates when a certain amount of data it received from pipe in is a full frame rgb image, processes it, and spits back hvec from pipe out.

    But it blocks as if it is accepting more data even though a full rgb image is piped in.

    Is what I am trying to do doable ?
