  • Automated installation script of MediaSPIP

    25 avril 2011, par

    To overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
    You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
    The documentation of the use of this installation script is available here.

  • exec function not working as expected

    6 mars 2016, par Albert

    I 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 correct

    However, 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 Elsdon

    I 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 user1568549

    In my jni module I copy images to bitmaps, 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 the GUI 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.
