Supporting all media types
13 avril 2011, parUnlike most software and media-sharing platforms, MediaSPIP aims to manage as many different media types as possible.

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) (...)

Les vidéos
21 avril 2011, parComme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

FFMPEG crash while cropping video
18 octobre 2022, par Khawar RazaI am using FFMPEG to crop a video. I am using ffmpeg-kit as a ffmpeg wrapper in my android app where the user can select any output size irrespective of the original video aspect ratio. Below is the problematic command :


-i "/storage/emulated/0/Download/83a2f6_1080p~2.mp4" -filter_complex "[0:v]crop=304:236:2:2[cropped]" -map "[cropped]" "/storage/emulated/0/DCIM/appname/vid_d8ee328d-ec7a-468b-9313-4561dceea33e.mp4"



When the execution starts, the application crashes.

I don't know what is wrong with the output width and height parameters. If I change
[0:v]crop=304:236:2:2[cropped]
to[0:v]crop=304:304:2:2[cropped]
with change in height, the process completes successfully. The original video (1080x808) is not smaller than the output size. It does not seem to be a problem in the video as I have tried different videos. Any tips on what is missing from my command ?
