  • 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.

  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • Segmenting video into different parts and unique rendering on each part then concat afterwards

    2 mars 2016, par goudarziha

    I currently have a very poorly performing application that splits up a video, renders it and the concats all rendered videos on android using ffmpeg

    So I am running into issues with segmenting a video up into 5 parts at each different intervals/durations, rendering each video segment uniquely slowing up/speeding up and then finally concat all the segments back into one final video.

    Currently I am doing each part separately -

    Segmenting -
    example for one segment
    -y -i pathIn -ss 0.0 -t 2.0 -vcodec copy -acodec copy -an pathOut

    Rendering - example slowing down/speeding up

    - y -i path -filter:v setpts=2.0*PTS pathOut

    Concat -

    - f concat -i input1.mp4 -i input2.mp4 -i input3.mp4 -i input4.mp4 -i input5.mp4 -c copy output.mp4

    Right now I am running different separate thread for each editing of video, so 3, segment, rendering and concat.

    I am trying to get this all done on one command ffmpeg line if at all possible, if not just the segmenting and rendering of the videos and kick of the concat cmd line later.

    I am trying to emulate something similar to this https://trac.ffmpeg.org/wiki/Creating%20multiple%20outputs

  • ffmpeg on ubuntu convert 3gp to iphone 5 format [closed]

    21 mars 2013, par Jistanidiot

    I'm desperately trying to convert a 3GP video into something the iphone 5 will import and play. Verizon says they cannot help me that it is not possible to convert a Droid video to iphone.

    After much trouble I came to the conclusion to try the conversion on my Ubuntu box using ffmpeg. Again after a long struggle, I removed the package and followed the directions at https://ffmpeg.org/trac/ffmpeg/wiki/UbuntuCompilationGuide

    Now with the new complied ffmpeg, I try the following command :

     ffmpeg -i foo.3gp -s 320x240 -r 30000/1001 -b:v 200k -bt 240k -vcodec libx264 -coder 0 -bf 0 -flags2 -wpred-dct8x8 -level 13 -maxrate 768k -bufsize 3M-acodec libfaac -ac 2 -ar 48000 -ab 192k output.mp4

    However I keep getting the error :

     [NULL @ 0xa9874a0] Unable to find a suitable output format for 'libfaac' libfaac: Invalid argument

    I found a random blog post saying you needed to add

    `-target type’

    and then specify target file type (“vcd”, “svcd”, “dvd”, “dv”, “dv50”, “pal-vcd”, “ntsc-svcd”, … ). However after trying all 8 of them listed I still got the same errors.

    I'm at a complete loss. How can I convert the 3gp video into the iphone 5 format ?

    Thanks in advance.

  • How do we determine the required dependencies for ffmpeg

    15 mars 2021, par user3656901

    I've installed ffmpeg on ubuntu. I am going to copy the compiled ffmpeg and required dependencies to a directory and copy that directory to another machine. This way we can run ffmpeg on another machine without installation. How do we determine the required dependencies to copy ? Saw instruction on this page : https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu, but it didn't explain the required dependencies for ffmpeg.

    


    When I used ldd ffmpeg, I got something like :

    


        linux-vdso.so.1 (0x00007fffe20fd000)
    libavdevice.so.58 => /lib/x86_64-linux-gnu/libavdevice.so.58 (0x00007fc116e90000)
    libavfilter.so.7 => /lib/x86_64-linux-gnu/libavfilter.so.7 (0x00007fc116b10000)
    libavformat.so.58 => /lib/x86_64-linux-gnu/libavformat.so.58 (0x00007fc116890000)
    libavcodec.so.58 => /lib/x86_64-linux-gnu/libavcodec.so.58 (0x00007fc1152d0000)
    libavresample.so.4 => /lib/x86_64-linux-gnu/libavresample.so.4 (0x00007fc1152a0000)
    libpostproc.so.55 => /lib/x86_64-linux-gnu/libpostproc.so.55 (0x00007fc115270000)


    


    Are those the required dependencies ? It didn't list the files under bin, include or share folders.
