La file d’attente de SPIPmotion
28 novembre 2010, parUne file d’attente stockée dans la base de donnée
Lors de son installation, SPIPmotion crée une nouvelle table dans la base de donnée intitulée spip_spipmotion_attentes.
Cette nouvelle table est constituée des champs suivants : id_spipmotion_attente, l’identifiant numérique unique de la tâche à traiter ; id_document, l’identifiant numérique du document original à encoder ; id_objet l’identifiant unique de l’objet auquel le document encodé devra être attaché automatiquement ; objet, le type d’objet auquel (...) -
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) (...)

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. The following are just a few examples from an ever-expanding list of supported formats : images : png, gif, jpg, bmp and more audio : MP3, Ogg, Wav and more video : AVI, MP4, OGV, mpg, mov, wmv and more text, code and other data : OpenOffice, Microsoft Office (Word, PowerPoint, Excel), web (html, CSS), LaTeX, Google Earth and (...)

FFMEG dumping a RTSP streaming works on Windows but not in Ubuntu
8 août 2016, par cuentafalsa7I have a camera with a
RTSP
server. When I try to save the streaming, usingFFMPEG
in Windows works ; in Ubuntu,FFMPEG
it doesn’t.The command, in Windows is :
ffmpeg.exe -i "rtsp://192.168.1.10:1236/?videoapi=mc&h264=1000-20-1280-960" -r 20 test.mp4
In Linux :
ffmpeg -i "rtsp://192.168.1.10:1236/?videoapi=mc&h264=1000-20-1280-960" -r 20 test.mp4
The output in Linux is :
$ ffmpeg -i "rtsp://192.168.1.10:1236/?videoapi=mr&h264=1000-20-1280-960" -r 20 test.mp4

Use -h to get full help or, even better, run 'man ffmpeg'I’m using Windows 7 64 bits and Ubuntu 16.04.
I have tried to increase the suggested values but didn’t work either.
Any idea, except switching to Windows ? -
How to fix a segmentaion fault in a C program ? [closed]
13 janvier 2012, par ipegasusPossible Duplicate :
Segmentation faultCurrently I am upgrading an open source program used for HTTP streaming. It needs to support the latest FFMPEG.
The code compiles fine with no warnings although I am getting a segmentation fault error.
I would like to know how to fix the issue ? and / or the best way to debug ? Please find attached a portion of the code due to size. I will try to add the project to github :) Thanks in advance !Sample Usage
# segmenter --i out.ts --l 10 --o stream.m3u8 --d segments --f stream
Makefile
FFLIBS=`pkg-config --libs libavformat libavcodec libavutil`
FFFLAGS=`pkg-config --cflags libavformat libavcodec libavutil`

ffmpeg : Pipe input error
1er septembre 2012, par Amit KhannaI'm facing an issue while working with ffmpeg when input and output are pipes. Though Output pipe is working fine, piping the input is causing some error.
I tried to convert mp4 video to flv using the following command and it worked fine :
$ ffmpeg -i video-2012-04-26-19-48-40.mp4 -ar 44100 -ab 96 -f flv pipe:1 | cat> videoname.flv
It worked fine and gave the following output :
