Déploiements possibles
31 janvier 2010, parDeux types de déploiements sont envisageable dépendant de deux aspects : La méthode d’installation envisagée (en standalone ou en ferme) ; Le nombre d’encodages journaliers et la fréquentation envisagés ;
L’encodage de vidéos est un processus lourd consommant énormément de ressources système (CPU et RAM), il est nécessaire de prendre tout cela en considération. Ce système n’est donc possible que sur un ou plusieurs serveurs dédiés.

Encoding and processing into web-friendly formats
13 avril 2011, parMediaSPIP automatically converts uploaded files to internet-compatible formats.
Video files are encoded in MP4, Ogv and WebM (supported by HTML5) and MP4 (supported by Flash).
Audio files are encoded in MP3 and Ogg (supported by HTML5) and MP3 (supported by Flash).

Why videos generated using FFMPEG in android doesn't play on all video players ?
9 juillet 2014, par Divya MotiwalaI am trimming a video using FFMPEG command mentioned below in android. It only plays with MX Player and not the default or any other player.
String trimVideoUrl = mFfmpegInstallPath + " -y -i " +
videoPath + " -ss " +
hms + " -t "+ duration +
" -async 1 -preset ultrafast -strict -2 "+ OUTPUT_FILENAME;Please let me know what other paramaters will help to make it run on other players. I did try
-c:v libx264but didn’t help. -
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 ?
