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) (...)

Other interesting software
13 avril 2011, parWe don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
We don’t know them, we didn’t try them, but you can take a peek.

avcodec/vp3 : Use range-based loop variables

FFMPEG screen regarding using gdi is working as expected when given offset, width and height on different screen size ?
15 novembre 2018, par Mohsin AbbasI am working on an application that records the screen using ffmpeg. The recording works fine when I don’t specify offset, width and height.
When I specify the offset, width and height on my device and records according to the area but when I run it on a big screen and it records smaller area than provided. I am using following command to record :ffmpeg -f gdigrab -framerate " + Framerate + " -offset_x " + OffsetX + " -offset_y " + OffsetY + " -video_size " + width + "x" + height + " -show_region 0 -i desktop " + FileName;I think ffmpeg don’t take screen resolution into account or something ?
