Script d’installation automatique de MediaSPIP
25 avril 2011, parAfin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

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) (...)

exec function not working as expected
6 mars 2016, par AlbertI am running a shell function from php to convert a video file to flash once it is uploaded. The exec function is like this :
exec("ffmpeg -i " . WWW_ROOT . "files" . DS . "videos" . DS . $id . $ext . " -ar 22050 -r 32 -f flv -s 640x480 " . WWW_ROOT . "files" . DS . "videos" . DS . $id . ".flv");
// if I echo the string it returns:
// ffmpeg -i /home/vceroot/public_html/example.com/test/intraweb/app/webroot/files/videos/516c1203-0484-417a-b047-5488c40293e9.mpg -ar 22050 -r 32 -f flv -s 640x480 /home/vceroot/public_html/example.com/test/intraweb/app/webroot/files/videos/516c1203-0484-417a-b047-5488c40293e9.flv
// the locations are correctHowever, it does not convert the video.
After it uploaded the file, it just goes back to the index action. There is no converted file although the uploaded file is there.
My permissions on the folder is 755. And the folder owner is apache. I don’t know what else to do. Can anyone assist me ?
UPDATE
So I’ve changed my exec query a bit and echoed the output :
exec("ffmpeg -i " . WWW_ROOT . "files" . DS . "videos" . DS . $id . $ext . " -ar 22050 -r 32 -f flv -s 640x480 " . WWW_ROOT . "files" . DS . "videos" . DS . $id . ".flv 2>&1", $output, $return);
die(print_r($output));This returned the following error :
Array ( [0] => sh: ffmpeg: command not found ) 1
So I changed it a bit to this :
exec("/usr/local/bin/ffmpeg -i " . WWW_ROOT . "files" . DS . "videos" . DS . $id . $ext . " -ar 22050 -r 32 -f flv -s 640x480 " . WWW_ROOT . "files" . DS . "videos" . DS . $id . ".flv 2>&1", $output, $return);
die(print_r($output));And now it returns :
Array ( [0] => /usr/local/bin/ffmpeg: error while loading shared libraries: libavdevice.so.55: cannot open shared object file: No such file or directory ) 1
Where do I go from here ?

ffmpeg in opencv 2.4
27 août 2012, par Josh ElsdonI am using opencv, but it is very pick with video types that it will open. I have version 2.4 of opencv and it apparently has ffmpeg support built in, though it does not open any movie files correctly, obj.grab() returns false and retrieve(frame,0) return NULL. So it seems to me that FFmpeg is not working correctly, is there something I need to do to turn it on, from internet searches people seem to suggest that from 2.4 onward it is a non-issue(though apparently not). Any help, all the other threads seem to just aout stop short of the answer for me.
(windows 7, Visual studio 2010, opencv 2.4)

AndroidBitmap_lockPixels failing with -3 code
24 avril 2013, par user1568549In my
jni
module I copy images tobitmaps
, which were previously
passed from my java application.I do this using
AndroidBitmap_lockPixels/AndroidBitmap_unlockPixels
.
Basically, it renders the image correctly, but there're strange
effects : sometimes the application gets stuck, or after some time
AndroidBitmap_lockPixels
always returns -3(ANDROID_BITMAP_RESULT_ALLOCATION_FAILED)
. I guess this is because I
update these bitmaps not from theGUI
thread, isn't it ?If so, what would be correct way to "post" this operation to the GUI
thread ? Is it possible in
jni
?Thanks.
