Abstract
(EN) A video transmission method, a movable platform and a computer-readable storage medium. The method comprises: acquiring a video coding rate (S101); and according to mapping relationships between the video coding rate and a frame rate and between a preset coding rate and the frame rate, determining a target frame rate at which a movable platform transmits a coded video to a terminal device (S102). As such, a video transmission frame rate can match a video coding rate, thereby improving the user experience.
(FR) Procédé de transmission vidéo, plateforme mobile et support d'enregistrement lisible par ordinateur. Le procédé comprend : l'acquisition d'un taux de codage vidéo (S101) ; et selon des relations de mappage entre le taux de codage vidéo et un débit de trame et entre un taux de codage prédéfini et le débit de trame, la détermination d'une fréquence de trame cible à laquelle une plateforme mobile transmet une vidéo codée à un équipement terminal (S102). Ainsi, une fréquence de trame de transmission vidéo peut correspondre à un débit de codage vidéo, ce qui permet d'améliorer l'expérience de l'utilisateur.
(ZH) 一种视频传输方法、可移动平台及计算机可读存储介质,其中该方法包括:获取视频编码码率(S101)根据所述视频编码码率和预设的码率与帧率之间的映射关系,确定所述可移动平台向所述终端设备传输编码后的视频的目标帧率(S102)。可以使得视频传输帧率与视频编码码率相匹配,提高用户体验。
