Publier sur MédiaSpip

13 juin 2013

Puis-je poster des contenus à partir d’une tablette Ipad ?
Oui, si votre Médiaspip installé est à la version 0.2 ou supérieure. Contacter au besoin l’administrateur de votre MédiaSpip pour le savoir
Que fait exactement ce script ?

18 janvier 2011, par kent1

Ce script est écrit en bash. Il est donc facilement utilisable sur n’importe quel serveur.
Il n’est compatible qu’avec une liste de distributions précises (voir Liste des distributions compatibles).
Installation de dépendances de MediaSPIP
Son rôle principal est d’installer l’ensemble des dépendances logicielles nécessaires coté serveur à savoir :
Les outils de base pour pouvoir installer le reste des dépendances Les outils de développements : build-essential (via APT depuis les dépôts officiels) ; (...)
Multilang : améliorer l’interface pour les blocs multilingues

18 février 2011, par kent1

Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

The recorded video is distorted (FFMPEG)

13 décembre 2017, par No Name

The source is taken from here.

I’m initializing this :

private void initRecorder() {

    Log.i(LOG_TAG, "init mFrameRecorder");



    String recordedTime = new SimpleDateFormat("yyyyMMdd_HHmmss", Locale.getDefault())

            .format(new Date());

    mVideo = CameraHelper.getOutputMediaFile(recordedTime, CameraHelper.MEDIA_TYPE_VIDEO);

    Log.i(LOG_TAG, "Output Video: " + mVideo);



    mFrameRecorder = new FFmpegFrameRecorder(mVideo, videoWidth, videoHeight, 1);

    mFrameRecorder.setFormat("mp4");

    mFrameRecorder.setSampleRate(sampleAudioRateInHz);

    mFrameRecorder.setFrameRate(frameRate);

    // Use H264

    mFrameRecorder.setVideoCodec(avcodec.AV_CODEC_ID_H264);

    mFrameRecorder.setVideoQuality(2);



    mFrameRecorder.setVideoOption("crf", "20");

    mFrameRecorder.setVideoOption("preset", "superfast");

    mFrameRecorder.setVideoOption("tune", "zerolatency");



    Log.i(LOG_TAG, "mFrameRecorder initialize success");

}

where frameRate = 60 ;

And video recording :

class VideoRecordThread extends RunningThread {

    @Override

    public void run() {

        List<string> filters = new ArrayList&lt;>();

        // Transpose

        String transpose = null;

            }

        }

        if (transpose != null) {

        }

        // Crop (only vertically)

        int width = previewHeight;

        int height = width * videoHeight / videoWidth;

        String crop = String.format(Locale.getDefault(),"crop=%d:%d:%d:%d",

                width, height,

                (previewHeight - width) / 2, (previewWidth - height) / 2);

        filters.add(crop);

        // Scale (to designated size)

        String scale = String.format(Locale.getDefault(),"scale=%d:%d", videoHeight, videoWidth);

        filters.add(scale);



        FFmpegFrameFilter frameFilter = new FFmpegFrameFilter(TextUtils.join(",", filters),

                previewWidth, previewHeight);

        frameFilter.setPixelFormat(avutil.AV_PIX_FMT_NV21);

        frameFilter.setFrameRate(frameRate);

        try {

                break;

            }

                long timestamp = recordedFrame.getTimestamp();

                    mFrameRecorder.setTimestamp(timestamp);

                }

                long startTime = System.currentTimeMillis();

                Frame filteredFrame = null;

                try {

                    frameFilter.push(recordedFrame.getFrame());

                    filteredFrame = frameFilter.pull();

                } catch (FrameFilter.Exception e) {

                    e.printStackTrace();

                }

                try {

                    mFrameRecorder.record(filteredFrame);

                } catch (FFmpegFrameRecorder.Exception e) {

                    e.printStackTrace();

                }

                long endTime = System.currentTimeMillis();

                long processTime = endTime - startTime;

                mTotalProcessFrameTime += processTime;

                Log.d(LOG_TAG, "This frame process time: " + processTime + "ms");

                long totalAvg = mTotalProcessFrameTime / ++mFrameRecordedCount;

                Log.d(LOG_TAG, "Avg frame process time: " + totalAvg + "ms");





            }

            Log.d(LOG_TAG, mFrameRecordedCount + " / " + mFrameToRecordCount);

            mRecycledFrameQueue.offer(recordedFrame);

        }

    }



    public void stopRunning() {

        super.stopRunning();

        if (getState() == WAITING) {

            interrupt();

        }

    }

}

</string>

The fact is that when recording video no lags(freezes) are not noticeable. After recording the video, when you look carefully, the lags are noticeable, and if you move the phone quickly when recording, then after the recording you can see the freezes, as if you have glued several GIFs.

I tried everything I could : the frame rate changed for 30, 60, 100. I changed the Video quality, pixelFormat (although I do not know why) and many things that

I did not understand. But still no use. Maybe there is someone who understands. Tell me how to correct these distortions(freezes) ?

Piwik 2.1 – Changes for Plugin developers

24 février 2014, par Piwik Core Team — Development
This blog post is aimed at developers of Piwik Plugins. If you are simply using Piwik and not developing plugins for Piwik, you do not need to read this post.

Piwik 2.1 will be released in a few days . This blog post will inform Piwik Plugin developers of the changes in Piwik 2.1 that may require that you update your plugin to work with this latest version.

Breaking API changes

Piwik can now handle an unlimited number of users having Super User access (#2589 #4564). In the past Piwik was limited to one Super User who was defined in the config file. From now on all users with Super User access are defined in the database the same way a regular user is. This brought some API changes but we will stay backward compatible until the first of April 2014. This gives you some time to migrate any custom plugins you may use. Although there is a layer for backward compatibility we recommend to make sure your plugin works with Piwik as soon as possible before April 1st.

List of changes

Deprecated methods

The following methods are deprecated and we recommend to use the new methods from now on. There are also some methods which won’t be replaced so make sure to adjust the logic of your plugin.
```
\Piwik\Piwik::isUserIsSuperUser =&gt; \Piwik\Piwik::hasUserSuperUserAccess

\Piwik\Piwik::setUserIsSuperUser =&gt; \Piwik\Piwik::setUserHasSuperUserAccess

\Piwik\Piwik::checkUserIsSuperUser =&gt; \Piwik\Piwik::checkUserHasSuperUserAccess

\Piwik\Access::isSuperUser =&gt; \Piwik\Access::hasSuperUserAccess

\Piwik\Access::checkUserIsSuperUser =&gt; \Piwik\Access::checkUserHasSuperUserAccess

\Piwik\Access::setSuperUser =&gt; \Piwik\Access::setSuperUserAccess

\FakeAccess::checkUserIsSuperUser =&gt; FakeAccess::checkUserHasSuperUserAccess

\FakeAccess::setSuperUser =&gt; FakeAccess::setSuperUserAccess

\Piwik\Piwik::isUserIsSuperUserOrTheUser =&gt; \Piwik\Piwik::hasUserSuperUserAccessOrIsTheUser

\Piwik\Piwik::checkUserIsSuperUserOrTheUser =&gt; \Piwik\Piwik::checkUserHasSuperUserAccessOrIsTheUser

\FakeAccess::getSuperUserLogin =&gt; No replacement

\Piwik\Piwik::getSuperUserLogin =&gt; No replacement, returns the userLogin of the first Super User we find in the database 

\Piwik\Piwik::getSuperUserEmail =&gt; No replacement, returns an empty string from now on

\Piwik\Access::getSuperUserLogin =&gt; No replacement, returns the userLogin of the first Super User we find in the database
```
Config Super User

As mentioned, the Super User was defined in the config and you have accessed the Super User’s data either by using a convenient method like Piwik::getSuperUserLogin or directly via the Config object as follows :
```
\Piwik\Config::getInstance-&gt;superUser
```
As the config user is no longer defined in the config this will no longer work in the future. To stay backward compatible we return the first super user found in the database. This is not necessarily always the same user. So if you have used the super user login in some way in your plugin, make sure you are using the new function such as Piwik::getSuperUserLogin

Extended Auth Interface

The last change affects plugins who specify their own Authentication mechanism, for instance when using the custom LoginLDAP plugin. From now on the interface \Piwik\Auth (https://github.com/piwik/piwik/blob/master/core/Auth.php) requires the methods setTokenAuth and setLogin. There is no backward compatibility layer but we had a look at some plugins defining a custom Authentication adapter to make sure those methods are already defined there as expected.

For another example of a Login plugin, check out the LoginHttpAuth plugin on the Marketplace.

After updating the plugin

After you have made changes in your plugin to keep it compatible with Piwik 2.1, your plugin will no longer work with previous Piwik versions. Therefore you should define the minimum required version in your plugin.json file as follows :
```
"require": {

 "piwik": "&gt;=2.1" 

}
```
Summary

Piwik 2.1 introduces some changes in the Piwik Core APIs. This blog post explains how to modify any Plugins compatible with Piwik 2.0 to be compatible with Piwik 2.1. Thank you for taking the time to update your plugins !

Let us know if you have any feedback. Happy hacking !

PS : if you use the Web Analytics APIs and the Web Tracking APIs, we guarantee that we will support backwards compatibility of our Web APIs.
