Je rencontre un problème pour lire des vidéos YouTube avec vlcj. Jusqu'à la semaine dernière, tout fonctionnait. J'appelais mediaPlayer.playMedia ("http://www.youtube.com/watch?v=1t8fl96HPQI") et fonctionnait bien mais pas plus. il ne produit aucune erreur du tout. Notez que je peux lire des fichiers locaux et d'autres URL de diffusion en ligne, mais pas des vidéos YouTube.Lecture de vidéos youtube avec vlcj ne fonctionne plus
Ceci est le code que j'utilise. (Essentiellement son exemple prêt)

/**
* A minimal YouTube player.
* <p>
* The URL/MRL must be in the following format:
* <pre>
* http://www.youtube.com/watch?v=000000
* </pre>
* The only thing that makes this different from a 'regular' media player
* application is the following piece of code:
* <pre>
* mediaPlayer.setPlaySubItems(true); // <--- This is very important for YouTube media
* </pre>
* Note that it is also possible to programmatically play the sub-item in
* response to events - this is slightly more complex but more flexible.
* <p>
* The YouTube web page format changes from time to time. This means that the
* lua scripts that vlc provides to parse the YouTube web pages when looking
* for the media to stream may not work. If you get errors, especially errors
* alluding to malformed urls, then you may need to update your vlc version to
* get newer lua scripts.

Pour les vidéos youtube vous voulez ce code:
mediaPlayer.setPlaySubItems(true); // <--- This is very important for YouTube media
et le code ci-dessous obtient tous les sous-éléments.
mediaPlayer.addMediaPlayerEventListener(new MediaPlayerEventAdapter() {
@Override
public void mediaSubItemAdded(MediaPlayer mediaPlayer, libvlc_media_t subItem) {
List<String> items = mediaPlayer.subItems();
System.out.println(items);
System.out.println(mediaPlayer.subItemCount());
}
});
Quand il travaillait, je remarquais que le code ci-dessus a été l'impression 2, l'un des sous-éléments d'entre eux étant l'URL de la vidéo.
Mais maintenant, il imprime un seul sous-élément comme ceci:
[http://www.youtube.com/get_video_info?video_id=1t8fl96HPQI & el = detailpage]
qui n'est pas l'URL de la vidéo et je pense que c'est pourquoi ne joue pas.
Des idées sur les raisons pour lesquelles cela se produit? Est-ce que google a changé quelque chose dans le format de ses pages youtube?
J'ai essayé de mettre à jour le fichier vlc youtube.lua comme cela a été suggéré dans un tutoriel que j'ai trouvé mais sans succès.
En outre, lorsque j'utilise le même lien dans vlc, cela fonctionne très bien.
Spécifications:
Ubuntu 12.0.4 64 bits
VLC media player 2.0.5 Twoflower
vlcj 2.2.0
Merci à l'avance,
Marios
