Configuration de JavaScript vidéo Apple TV

J'ai une fonction simple qui va lancer la player qui gère la lecture vidéo pour l'Apple TVConfiguration de JavaScript vidéo Apple TV

function launchPlayer() { 
    var player = new Player(); 
    var playlist = new Playlist(); 
    var mediaItem = new MediaItem("video", "http://localhost:9001/videos/nsoperations.mp4"); 
    player.playlist = playlist; 
    player.playlist.push(mediaItem); 
    player.present(); 
}

Selon le Player Documentation, tout ce que je besoin de lire une vidéo est un joueur de retour , une playlist (docs) et un élément multimédia (docs). J'ai tout cela, mais quand j'utilise mon code, j'obtiens une erreur: Unable to simultaneously satisfy constraints. Pour ma compréhension, nous ne traitons pas la mise en page automatique pour ces lecteurs intégrés. Ai-je mal utilisé le joueur?

détails d'erreur est la suivante:

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger. 
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful. 
2015-09-11 07:36:00.146 TestingTVML[3354:323153] Unable to simultaneously satisfy constraints. 
    Probably at least one of the constraints in the following list is one you don't want. 
    Try this: 
     (1) look at each constraint and try to figure out which you don't expect; 
     (2) find the code that added the unwanted constraint or constraints and fix it. 
    (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints)

Vous utilisez ceci en environnement local, oui? Et http: // localhost: 9001/videos/nsoperations.mp4 est-il accessible? – Cosmin

oublié d'ajouter cela - oui, je cours environnement local, et j'ai été en mesure d'atteindre 'localhost: 9001' pour faire face à d'autres modèles. –

J'ai cliqué sur le lien que vous avez fourni, j'ai eu la vidéo. Merci pour ce bon chèque! –

Votre échantillon est ok et fonctionnent. Même avec les erreurs de contrainte, mais le joueur n'est pas très indulgent.

Je pense que vous utilisez le SimpleHTTPServer Python pour votre test, cela n'a pas fonctionné pour le streaming vidéo, mais si vous utilisez Apache ou par exemple ce fichier directement à partir de Apple "http://trailers.apple.com/movies/focus_features/9/9-clip_480p.mov" cela fonctionnera.

je t'aime, merci pour le pointeur. Cela va beaucoup aider. –

Ceci est correct. Je pense que la lecture vidéo nécessite que le serveur prenne en charge, entre autres, les requêtes d'octets. – lemnar

Oui, les demandes de gamme d'octets sont exigées par des trucs vidéo, je me souviens d'avoir rencontré le même problème lors de l'exécution de l'audio/vidéo embarquée dans le rendu ePub lors de Kobo. –

J'ai eu le même problème. Il s'avère que SimpleHTTPServer de Python n'est pas capable de diffuser de la vidéo et est un exemple pauvre (minimaliste) à utiliser. Je suis allé avec http-server à la place et cela fonctionne parfaitement. Ceci est la syntaxe je (sur mon Mac):

$ npm install http-server -g 
$ http-server ./ -p 9001 -a 192.168.16.105

où:

./ est le chemin vers la racine du serveur web

-p 9001 est le port que vous souhaitez utiliser

-a 192.168.16.105 est l'adresse IP que vous voulez desservir

Vous pouvez vérifier que cela fonctionne correctement en ouvrant un navigateur web et de faire quelque chose comme:

http://192.168.16.105:9001/myvideo.mp4

(assurez-vous juste que vous avez un fichier vidéo dans ce dossier à lire)
