Script d’installation automatique de MediaSPIP
25 avril 2011, parAfin 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.

Trying to convert frames to a video using ffmpeg in a batch script [closed]
21 octobre 2020, par KatzenwerferI'm doing a script to convert frames into a video.


@echo off
set /p ftv="Want to covert the frames to video (yes or no): "
if %ftv%==yes (echo Ok, initializing frame convertion... & timeout 1 >nul & set /p framerate="Please specify the framerate: " & set /p crf="Please specify a CRF value: " & timeout 1 >nul & ffmpeg -framerate %framerate% -i "%cd%\Interpolated_frames\%%6d.png" -c:v libx264 -preset veryslow -crf %crf% "%cd%\FinalVideo.mp4" & echo Video ready, check the folder for the final video & timeout 1 >nul)



It is suppposed to let you choose the framerate and the crf value, but when running it, ffmpeg gives me
Output file #0 does not contain any stream


Dividing it into singular parts like this make it work, but I need to use it with the if


@echo off 
echo Ok, initializing frame convertion...
timeout 1 >nul
set /p framerate="Please specify the framerate: "
set /p crf="Please specify a CRF value: "
timeout 1 >nul & ffmpeg -framerate %framerate% -i "%cd%\Interpolated_frames\%%6d.png" -c:v libx264 -preset veryslow -crf %crf% "%cd%\FinalVideo.mp4"
echo Video ready, check the folder for the final video
timeout 1 >nul
