and 204, determining the direction of the component of the directional line on a preset coordinate axis in the rectangular plane coordinate system as the original video display direction of the video to be displayed on the plane where the display screen is located.
Specifically, the image frame in this embodiment may be a first frame image of a video, and the display subject is also a main display object in the video to be displayed, for example, when the terminal user performs a video call, the display subject in the video is also an opposite-end user. In addition, the feature point in the present embodiment is a point on a portion of the video to be displayed on the display main body that satisfies a preset feature (for example, a shape feature, a color feature, or the like).
Fig. 3 is a schematic diagram of the original video display direction provided by this embodiment, in which two feature points of this embodiment are respectively center points of a mouth and eyes of a video image main body, and a connection rule of the feature points on the main body is that the feature points from the upper part to the lower part of the main body are connected, and as shown in fig. 3, a directed line is formed by connecting the feature points on the eyes to the feature points of the mouth. It should be noted that, in this embodiment, the original video display direction is associated with the direction of the X-axis component or the Y-axis component of the directional line, the rectangular plane coordinate system is shown in the lower left corner of the display screen in fig. 3, as shown in fig. 3, when the terminal is held by the user in the vertical direction, the video display direction should be aligned with the direction of the X-axis component (shown by the arrow with the broken line) of the coordinate axis, and in other embodiments, when the terminal is held in the horizontal direction, the video display direction should be aligned with the direction of the Y-axis component of the coordinate axis under the same coordinate axis.

In an optional implementation manner of this embodiment, before determining an original video display direction of a video to be displayed on a plane where a display screen is located, the method further includes: acquiring video identification information of a video to be displayed; inquiring a preset rotation angle index table through the video identification information, and judging whether the inquiry is successful; the rotation angle index table is a corresponding relation table between preset video identification information and a rotation angle; and when the query is successful, directly adjusting the video to be displayed to the display direction of the target video through the target rotation angle obtained by the query.
Specifically, the rotation angle index table in this embodiment may be generated by associating the calculated rotation angle with the video identification information of the video to be displayed based on the foregoing embodiments, while in other embodiments, the rotation angle may be generated by manually editing the rotation angle by the end user and then associating the rotation angle with the corresponding video identification information, or may be obtained from a backend server, which is not limited herein.
In this embodiment, when a video display direction adjustment requirement is detected, it is first determined whether a result of the video to be displayed can be queried in the rotation angle suggestive table, and when the query is successful, the video display direction adjustment can be directly performed based on the queried rotation angle without calculating the rotation angle after acquiring the original video display direction and the display screen direction, so that the processing efficiency of the terminal can be effectively improved; and when the query is not successful, the step of determining the original video display direction of the video to be displayed on the plane where the display screen is located is executed so as to meet the requirement of adjusting the video display direction.
