Support de tous types de médias
10 avril 2011Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

Automated installation script of MediaSPIP
25 avril 2011, parTo 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.

FFmpeg black screen using mpeg2video
16 juin 2020, par KonataI have a proprietary piece of hardware for broadcasting, that accepts extremely specific video format.
The software that we use for it is extremely slow and outdated.



I was looking at adapting FFmpeg to convert .avi/.mp4/etc to the specific format which in our case is





.mpg ( 720*576 16:9, 25FPS, MPEG Video PAL v.2 (Main@High) BVOP)
 acceptable bitrate is 9000k - 15000k.





So I have constructed this FFmpeg command :



-i input.avi -codec:a mp2 -b:a 384k -c:v mpeg2video -aspect 16:9 -bf 2 -b:v 10000k -maxrate 10000k -minrate 10000k -bufsize 5000k -profile:v main -level:v 4.0 output.mpg



The audio is working fine, but instead of video I get a black screen, this is the conversion log



"E:\auto_video\ffmpeg\bin\ffmpeg.exe" -i input.avi -codec:a mp2 -b:a 384k -c:v mpeg2video -aspect 16:9 -bf 2 -b:v 10000k -maxrate 10000k -minrate 10000k -bufsize 5000k -r 25 -profile:v main -level:v 4.0 output.mpg

How can I extract bonus images from a tv show DVD using ffmpeg ?
5 avril 2020, par HatemI'm using MakeMKVcon to automate episodes extraction. It do the job, expect the metadata. I have to rename files manually. But the problem here is that I want to extract some bonus pictures slideshow from the ISO but no software can detect it. I can only display those images using VLC (using the ISO file).



Do you have any idea how to do that ?
