In this embodiment, during the video playing process, the video player may further continue to load the remaining video stream of the second video, so that the user may view the video uninterruptedly and smoothly, and further bring a good experience effect to the user.

In this step, for the user, the user selects the first video to play, plays the first video thumbnail of the second video after the first video is played, and plays the second video after a period of time.

Therefore, in the technical scheme provided by the embodiment of the application, when the difference value between the current playing time and the ending time of the first video is determined to be the preset time threshold, the image player is started to load the preset first video thumbnail of the second video, and after the first video is determined to be played, the image video player plays the first video thumbnail, so that after the video stream in the preset time period is determined to be loaded, the video player is controlled to play the second video, and the loading time of the switching process of switching the first video to the second video is shortened. Therefore, by applying the technical scheme provided by the application, the loading time of the video switching process can be shortened, and a good experience effect is brought to a user.

In practical applications, there may be situations such as artificial exit or abnormal exit during the video playing process, and for such situations, as an embodiment, as shown in fig. 7, when it is determined that the first video is interrupted during the playing process, the following steps 104 to 105 may also be included:

and 104, generating a second video thumbnail of the first video at the current moment, starting the image player to play the second video thumbnail, and sending continuous playing prompt information for prompting whether a user continues playing to the image player. If the resume operation information of the play information indicating resume selected by the user is received, step 105 is executed, and if the resume operation information of the play information indicating non-resume selected by the user is received, the process is ended.

Here, the second video thumbnail is named for convenience of description only, and is not intended to limit a certain video thumbnail.

As an embodiment, when the playing of the first video is interrupted, the video player sends interruption prompt information for indicating the interruption of the video to the controller, so that the controller determines the interruption of the first video according to the interruption prompt information. As an embodiment, the interruption hint information may carry the current time.

As an embodiment, the resume prompt information may be played by using a voice broadcast function, so that the user can determine whether to resume the broadcast, and convenience can be brought to users with poor eyesight.

In this step, the generated second video thumbnail of the first video at the current time can enable a user to clearly know where the first video is off-air, and can also bring a prompt effect to the user and further bring a good experience effect.

Step 105, starting the video player to load the video stream of the first video in a preset time period after the current time, so as to close the image player after the first video in the preset time period is completely loaded, and starting the video player to play the first video after the current time.

As an embodiment, the video player may find a video stream location matching the first video thumbnail from a source corresponding to the first video according to the second video thumbnail.
