Abstract
(EN)
Disclosed are a video processing method and apparatus, and an electronic device and a computer-readable medium, relating to the technical field of video processing. The method comprises: parsing a video file to be played to acquire an audio stream and a video stream, wherein the video file to be played is an online video; generating a subtitle stream according to the audio stream; combining the subtitle stream with the video stream to obtain a target video stream; and displaying the target video stream on a screen. Therefore, when a user watches an online video without subtitles, the electronic device can automatically generate subtitles according to an audio stream of the video, and displays the subtitles on an interface where the video is played, so that the user can acquire video content more timely and accurately, thereby improving the user experience.

La présente invention concerne un procédé et un appareil de traitement vidéo, un dispositif électronique et un support lisible par ordinateur, se rapportant au domaine technique de traitement vidéo. Le procédé consiste à : analyser un fichier vidéo à lire pour acquérir un flux audio et un flux vidéo, le fichier vidéo à lire étant une vidéo en ligne; générer un flux de sous-titres selon le flux audio; combiner le flux de sous-titres avec le flux vidéo pour obtenir un flux vidéo cible; et afficher le flux vidéo cible sur un écran. Par conséquent, lorsqu'un utilisateur regarde une vidéo en ligne sans sous-titres, le dispositif électronique peut générer automatiquement des sous-titres selon un flux audio de la vidéo, et afficher les sous-titres sur une interface de lecture de la vidéo de sorte que l'utilisateur peut acquérir un contenu vidéo de manière plus opportune et précise, ce qui permet d'améliorer l'expérience de l'utilisateur.
