Abstract
(EN) The present invention relates to the field of cloud platforms. Provided is a video stream processing method. The method comprises: obtaining multiple video streams for a live streaming event; determining respective feature information of the multiple video streams; in response to a video request message from a client, determining feature information of the client; separately matching the respective feature information of the multiple video streams with the feature information of the client to obtain respective matching degrees of the multiple video streams with respect to the client; and on the basis of the respective matching degrees of the multiple video streams with respect to the client, selecting one video stream from the multiple video streams and pushing the video stream to the client. The present invention also provides a video stream processing apparatus, a computer device, and a medium.
(FR) La présente invention, qui appartient au domaine des plateformes infonuagiques, concerne un procédé de traitement de flux vidéo. Le procédé comprend : l’obtention de multiples flux vidéo pour un événement de diffusion continue en direct ; la détermination d’informations caractéristiques respectives des multiples flux vidéo ; en réponse à un message de demande de vidéo provenant d’un client, la détermination d’informations caractéristiques du client ; la mise en correspondance de manière séparée des informations caractéristiques respectives des multiples flux vidéo avec les informations caractéristiques du client pour obtenir des degrés de correspondance respectifs des multiples flux vidéo par rapport au client ; et sur la base des degrés de correspondance respectifs des multiples flux vidéo par rapport au client, la sélection d’un flux vidéo parmi les multiples flux vidéo et la poussée du flux vidéo vers le client. La présente invention concerne en outre un appareil de traitement de flux vidéo, un dispositif informatique et un support.
