Installation en mode ferme
4 février 2011, parLe mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
C’est la méthode que nous utilisons sur cette même plateforme.
L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...) -

La sauvegarde automatique de canaux SPIP
1er avril 2010, parDans 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 (...)

ffmpeg - error processing files generated by premier pro 2022
23 mai 2022, par QRrabbitPlease help with the error, trying to re-encode the source file produced with prores 4444+alpha. Alpha channel is required in my case.


I've tried two separate options, both are erroring out :


$ ffmpeg -i Input.mxf -vcodec prores_ks -profile:v 4 -y Output.mxf 



I'm getting this output

Above I can't even fully see the error since the red text over black background covers the screen :



I have also tried the following encoding options :


-c:v qtrle -pix_fmt argb 



to which, I'm getting the following error :


track 0: could not find essence container ul, codec not currently supported in container
Could not write header for output file #0 (incorrect codec parameters ?): Operation not permitted

Conversion failed!



In case this is helpful, I'm displaying MediaInfo for the source file :

Trouble building ffmpeg with cuda for windows 32 with visual studio 2022
27 juillet 2022, par manouHere is my building process


I open mingw32 from the x64 Native Tools Command Prompt for VS 2022


then in the mingw32 shell :


# cd /
# ./c/Program\ Files/Microsoft\ Visual\ Studio/2022/Community/VC/Auxiliary/Build/vcvars32.bat
# cd ~
# pacman -Sy diffutils git make gcc yasm pkg-config --noconfirm
# git clone --depth 1 https://git.ffmpeg.org/ffmpeg.git ffmpeg 
# git clone https://git.videolan.org/git/ffmpeg/nv-codec-headers.git nv-codec-headers 
# cd nv-codec-headers/
# make PREFIX=/usr/local
# make install PREFIX=/usr/local
# cd ..
# mkdir nv_sdk

# make -j8

first I have a bunch of warnings during the making looking like that :

libavutil/opt.c(1075): warning C4133: 'fonction' : types incompatibles - de 'AVPixelFormat *' à 'int *'


And finally the make install returns :

What am I doing wrong ?
shall I install others packets from pacman ?
