Title (EN) SEEKING IN LIVE-TRANSCODED VIDEOS
(FR) RECHERCHE DANS DES VIDÉOS TRANSCODÉES EN DIRECT
Abstract:
(EN) Systems and methods for implementing seeking functionality in a live-transcoding environment provide a computing device that includes input/output circuitry, a memory module storing a media player program, and control circuitry. The control circuitry is configured to connect to a data storage server over a network connection, send a first request to the data storage server for a video file, the first request including a first timestamp parameter, receive a first transcoded video stream from the server, present the first transcoded video stream and a video presentation interface associated with the media player program to a user, present a custom seek bar to the user, receive seeking input associated with the custom seek bar, the seeking input indicating a second time associated with the video file, and send a second request to the data storage server for the video file including a second timestamp parameter indicating the second time.
(FR) L'invention concerne des systèmes et des procédés pour mettre en œuvre une fonctionnalité de recherche dans un environnement de transcodage en direct, lesdits systèmes et procédés fournissant un dispositif informatique qui comprend un ensemble de circuits d'entrée/de sortie, un module de mémoire stockant un programme de lecteur multimédia et un ensemble de circuits de commande. L'ensemble de circuits de commande est configuré de sorte à être connecté à un serveur de stockage de données sur une connexion réseau, à envoyer une première requête au serveur de stockage de données pour un fichier vidéo, la première requête comprenant un premier paramètre d'horodatage, à recevoir un premier flux vidéo transcodé en provenance du serveur, à présenter le premier flux vidéo transcodé et une interface de présentation vidéo associée au programme de lecteur multimédia à un utilisateur, à présenter une barre de recherche personnalisée à l'utilisateur, à recevoir une entrée de recherche associée à la barre de recherche personnalisée, l'entrée de recherche indiquant un second moment associé au fichier vidéo et à envoyer une seconde requête au serveur de stockage de données pour le fichier vidéo comprenant un second paramètre d'horodatage indiquant le second moment.
