MediaSPIP Core : La Configuration

9 novembre 2010, par kent1

MediaSPIP Core fournit par défaut trois pages différentes de configuration (ces pages utilisent le plugin de configuration CFG pour fonctionner) : une page spécifique à la configuration générale du squelettes ; une page spécifique à la configuration de la page d’accueil du site ; une page spécifique à la configuration des secteurs ;
Il fournit également une page supplémentaire qui n’apparait que lorsque certains plugins sont activés permettant de contrôler l’affichage et les fonctionnalités spécifiques (...)
MediaSPIP Player : problèmes potentiels

Le lecteur ne fonctionne pas sur Internet Explorer
Sur Internet Explorer (8 et 7 au moins), le plugin utilise le lecteur Flash flowplayer pour lire vidéos et son. Si le lecteur ne semble pas fonctionner, cela peut venir de la configuration du mod_deflate d’Apache.
Si dans la configuration de ce module Apache vous avez une ligne qui ressemble à la suivante, essayez de la supprimer ou de la commenter pour voir si le lecteur fonctionne correctement : /** * GeSHi (C) 2004 - 2007 Nigel McNie, (...)
Encoding and processing into web-friendly formats

13 avril 2011, par kent1

MediaSPIP 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).
Where possible, text is analyzed in order to retrieve the data needed for search engine detection, and then exported as a series of image files.
All uploaded files are stored online in their original format, so you can (...)

Building my JAVA parameter array for FFMPEG

29 janvier 2016, par user3541092

FFmpeg Version : N-63893-gc69defd Copyright (c) 2000-2014 the FFmpeg developers
built on Jul 16 2014 05:38:01 with gcc 4.6 (Debian 4.6.3-1)

Machine : Amazon Linux t2.micro (free tier)

Sample File : sample_iTunes.mov
Sample File URL : https://support.apple.com/en-us/HT201549

I’m trying to replicate the following FFmpeg command, using a string array and then pass this array into the Runtime.getRuntime().exec().

ffmpeg -i file:/var/local/ffmpegtest/media_input/sample_iTunes.mov -pix_fmt yuv420p -c:v libx264 -vtag mp42 -metadata major_brand="mp42" -b:v 8000k -minrate 8000k -maxrate 10000k -ac 2 -strict experimental -c:a aac -b:a 256k -metadata:s:a:0 handler="Stereo" /var/local/ffmpegtest/media_output/sample_iTunes.mp4 -y

NOTE : This works when I pass the full command, as a single string into Runtime.getRuntime().exec().

    String _cmd = "ffmpeg -i %s -pix_fmt yuv420p -c:v libx264 -vtag mp42 -metadata major_brand=\"mp42\" "

            + "-b:v 8000k -minrate 8000k -maxrate 10000k -ac 2 -strict experimental -c:a aac -b:a 256k -metadata:s:a:0 handler=\"Stereo\" %s -y";

    String _ffmpegCommand = String.format(_cmd, _inputFile, _outPutFile);

    p = Runtime.getRuntime().exec(_ffmpegCommand);

    BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));



    String _line = null;



    while((_line = _reader.readLine()) != null) {

        lw.writeLine(_logPath + _logName, _line);

        System.out.println(_line);

    }

I started out with just a basic parameter list. As I add add each additional parameter, I re-build the JAR file and upload it to my EC2 instance to test for any errors.

The following string array works :

try

        {

            String[] _params = {"ffmpeg",

                       "-i",

                       String.format("%s", _inputFile),

                       "-pix_fmt",

                       "yuv420p",

                       "-c:v",

                       "libx264",

                       String.format("%s", _outPutFile),

                       "-y"};



            p = Runtime.getRuntime().exec(_params);



            BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));



            String _line = null;



            while((_line = _reader.readLine()) != null) {

                lw.writeLine(_logPath + _logName, _line);

                System.out.println(_line);

            }

        }

        catch (Exception e) {

            BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));



            String _line = null;



            while((_line = _reader.readLine()) != null) {

                lw.writeLine(_logPath + _logName, _line);

                System.out.println(_line);

            }



        }

However, when I continue to build the array with additional parameters, I begin to experience problems (lets add -vtag mp42) :

try

        {

            String[] _params = {"ffmpeg",

                       "-i",

                       String.format("%s", _inputFile),

                       "-pix_fmt",

                       "yuv420p",

                       "-c:v",

                       "libx264",

                       "-vtag", // &lt;---- New

                       "mp42", // &lt;---  New

                       String.format("%s", _outPutFile),

                       "-y"};



            p = Runtime.getRuntime().exec(_params);



            BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));



            String _line = null;



            while((_line = _reader.readLine()) != null) {

                lw.writeLine(_logPath + _logName, _line);

                System.out.println(_line);

            }

        }

        catch (Exception e) {

            BufferedReader _reader = new BufferedReader(new InputStreamReader(p.getErrorStream()));



            String _line = null;



            while((_line = _reader.readLine()) != null) {

                lw.writeLine(_logPath + _logName, _line);

                System.out.println(_line);

            }



        }
