Distributed Multimedia Database System Phase 2
Context And Goals
Due to the interest of G.I.S.S. users in the mediabase component version 1.0 released previously, as a real alternative to public systems like YouTube or Vimeo, improvements should be made to the actual mediabase version 1.0, to include more features like playlists, favorites, ...
Setting up the next developments
To achieve a number of new features like playlist or annotations, we first had to modify the cortado with two additional functionalities :
Cortado = document.getElementById("cortado"); timecode = Cortado.getPlayPosition();
<applet code="com.fluendo.player.Cortado.class" archive="cortado-ovt-debug-giss.jar" height="240" width="320" MAYSCRIPT> <param name="endCallback" value="nextTrack();">
For using these features, you will need to download the [Giss Cortado], which is based on Cortado 0.2.2.
CVS version of cortado G.I.S.S.
The G.I.S.S. cortado can be checked through CVS :
export CVSROOT=:pserver:email@example.com:/home/cvs cvs co cortado-giss
Adding of new blocks and funcionalities
- Added a block of most viewed videos on the channel, updating the counter through ajax when a video is requested
- Added a voting system and a block of favorite videos
Migration from version 1.0
If you have installed a version 1.0, you will need to do the following to the database, not to recreate it from scratch :
mysql> alter table media add column viewed int(10) not null default 0;
mysql> insert into blocks values (NULL,'most_viewed','video',2,8,397,100,1,<user id>,NULL); for users you have created before
mysql> CREATE TABLE `favorites` ( -> `ID` int(4) unsigned NOT NULL auto_increment, -> `channel` varchar(256) collate utf8_bin NOT NULL, -> `base_url` varchar(256) collate utf8_bin NOT NULL, -> `media_id` int(4) NOT NULL, -> `votes` int(4) NOT NULL DEFAULT 0, -> UNIQUE KEY `ID` (`ID`) -> ) ENGINE=MyISAM AUTO_INCREMENT=0 DEFAULT CHARSET=utf8 COLLATE=utf8_bin;
mysql> insert into blocks values (NULL,'favorites','video',2,9,397,100,1,<user id>,NULL); for users you have created before
