  • 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 (...)

  • Script d’installation automatique de MediaSPIP

    25 avril 2011, par

    Afin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
    Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

  • streaming from generated images using ffmpeg / vlc / live555

    10 octobre 2019, par Pavel

    For the life of me I cannot get this to work correctly.

    The idea is : simple python script that loads an image from a url (different every time) and passes it to ffmpeg, eg :

    python fetch.py | ffmpeg -f image2pipe -framerate 1 -i pipe:.jpg -c:a copy -c:v libx264 -r 5 -b 500000 -s 600x480 ../live555/out.264

    What I really need is to make this work with some sort of rtsp server.
    So far a sort of working approach was to use live555MediaServer that is running on the same server and pretty much streams that out.264 file.

    Why I don’t like this approach :

    a. connecting to rtsp stream using vlc works but it’s very unstable (video stops) and there are not errors or anything, if I click play it resumes.
    debug :
    live555 debug: RTSP track Close, 0 track remaining
    It seems like it just streams whatever the file has at that moment of time and does not do it continuously.

    b. I don’t like the "file" approach. Eg. ffmpeg is creating an out.264 file which grows. Ideally it would simply send the stream to the RTSP server via some protocol.

    c. live555MediaServer just sucks

    It looks like there is a way to run vlc server on my server as well, but I cannot figure out how to make ffmpeg feed the vlc server ?

    Any suggestions ?

  • Output image twice in ffplay

    2 mai 2024, par Sun Tzun

    I need to show two similar images from a webcam side-by-side.
I can achieve this with this piped command, but it runs with a few seconds latency :

    


    ffmpeg -f dshow -i video="Logi C310 HD WebCam" -filter_complex "[0:v][0:v]hstack=inputs=2[v]" -map "[v]" -f matroska - | ffplay -


    


    I'd prefer to do the same in just ffplay.

    


    I'd also like to have the resulting image cropped to a square size or to the size of the original image (like if the picture from webcam gets divided by half and the halfs took each other places).

    


    What I need in this end is a tool that helps to align the camera parallelly to the captured object, so any wrong angle would be perfectly visible on video if two opposite sides of the picture are placed alongside.

    


    PS. My platform is Windows 11.

    


  • ffmpeg : concat two clips vertically, but upper one should be bigger

    19 juillet 2022, par Rittari771

    I have two 1920x1080 clips. I know how to concat two clips vertically (the clips share equally the space half, 50% upper clip - 50% bottom) => what would i need to do to get a ratio like 65% 35% ?
So the upper clip would take 65% of the screen space vertically, then the lower bottom clip would fill the rest 35% ?

    


    this is my current code to concat the clips vertically.

    


    ffmpeg -i clip_top.mp4 -i clip_bottom.mp4 -filter_complex "vstack=inputs=2" -vsync 2 final_clip.mp4


    


    here is the same explanation, but with a picture : enter image description here
