Specifically, the similarity between the image of the first position area in the first video frame and the image of the second position area in the second video frame is greater than or equal to a second threshold, the second video frame is any one of the at least one video frame, and the position of the first position area in the first video frame is the same as the position of the second position area in the second video frame.
In an optional implementation manner, the presentation request carries a timestamp (T) corresponding to the playing of the first video frame in the first video. The above process of determining at least one video frame in a video stream can be implemented as follows:
(1) calculating the image similarity between the video frame (marked as P-1) corresponding to the previous moment (T-1) of the T moment and the first video frame by taking the first video frame (marked as P) of the T moment as a reference, and if the similarity is greater than or equal to a first threshold value, for example, 70%; further determining a position area M where the designated mark element in P is located and the same position area in P-1, and marking as M-1, calculating that the image similarity of M and M-1 is greater than a second threshold value, for example, 90%, and then determining that P-1 is a similar frame of P; continuing to calculate the image similarity of the video frame (noted as P-2) corresponding to the time (T-2) before the time T-1 and the first video frame (noted as P), if the similarity is greater than or equal to a first threshold value, for example, 70%; further determining a position area in P-2, which is the same as the position area of the designated marking element in P, and marking as M-2, calculating that the image similarity of M and M-2 is greater than a second threshold value, for example, 90%, and then determining that P-2 is a similar frame of P; and repeating the steps until the video frame corresponding to a certain time (T-i) before the T time cannot be determined as the similar frame of the first video frame according to the calculation mode, and stopping the calculation. For example, assume that the image similarity of the video frame (noted as P-3) corresponding to the previous time (T-3) of T-2 and the first video frame (noted as P) is less than the first threshold; and/or if the image similarity of M-3 in the same position region M-3 in P as the designated mark element is in P and the image similarity of M in P is smaller than a second threshold value, stopping calculation, and determining P-1 and P-2 as similar frames of P.
(2) Similarly, with the first video frame (P) at the time T as a reference, sequentially judging whether the video frames corresponding to the consecutive time after the time T can be used as the similar frames of the first video frame according to the above calculation manner, that is, if the image similarity between P and P + i is judged to be greater than or equal to a first threshold value, and the image similarity between M + j in the same position areas M and P + i in P is judged to be greater than or equal to a second threshold value, determining that P + i is the similar frame of P; and judging that the image similarity of the P and the P + i is smaller than a first threshold value, and/or determining that the P + i can not be used as a similar frame of the P if the image similarity of the M + j in the same position areas of the M and the P + i in the P is smaller than a second threshold value, namely that the P + i is not similar to the P, and stopping calculation.
For example, with reference to a first video frame (note as P) at time T, calculating image similarity between a corresponding video frame (note as P +1) at time (T +1) later than time T and the first video frame, if the similarity is greater than or equal to a first threshold, for example, 70%; further determining a position area M where the designated mark element in P is located and an area with the same position in P +1, and marking as M +1, calculating that the image similarity of M and M +1 is greater than a second threshold value, for example, 90%, and determining that P +1 is a similar frame of P; continuing to calculate the image similarity between the video frame (marked as P +2) corresponding to the time (T +2) subsequent to the time (T +1) and the first video frame (marked as P), if the similarity is greater than or equal to the first threshold, for example, 70%; further determining a position area in P +2, which is the same as the position area of the designated marking element in P, and marking as M +2, calculating that the image similarity of M and M +2 is greater than a second threshold value, for example, 90%, and then determining that P +2 is a similar frame of P; continuously calculating that the image similarity of the video frame (marked as P +3) corresponding to the later moment (T +3) of the T +2 and the first video frame (marked as P) is smaller than a first threshold value; and/or if the image similarity of M in the same position region M +3 in P +3 and the same position region M +3 in P where the specified marking element is located is less than a second threshold value, stopping the calculation, and determining P +1 and P +2 as similar frames of P.
(3) And taking the first video frame at the T moment as a reference, and searching at least one video frame which can be taken as a similar frame of the first video frame before and after the T moment so as to determine the video segment. The video segment includes a plurality of video frames that are temporally consecutive including the first video frame, such as P-2, P-1, P, P +1, and P +2 in the above example.
And further, in the first video stored in the server, comment information corresponding to the specified marking elements on the video frames contained in the video clips is retrieved according to a merging and counting algorithm, and the comment information is sent to the terminal equipment for displaying.
In an optional implementation manner, a function control for a user to vote for existing comments in a video can be set in the video displayed by a terminal device, and a server receives the number of votes of the existing comments periodically sent by the terminal device, wherein the terminal device can update the number of votes of the existing comments locally cached by the terminal device when monitoring that the user triggers a voting operation for a certain existing comment, and send the current number of votes of the existing comments to the server according to a preset period. Based on this, the presentation response sent by the server to the terminal device further includes the number of votes of each comment included in the comment information, so that the terminal device presents the comments included in a certain comment information in the order of the number of votes from large to small.

Further, to facilitate understanding of the video presentation method, referring to fig. 4, an embodiment of the present application further provides a flowchart of an interaction method, specifically describing interactions among a user, a terminal device, and a server in the video presentation method, where the interaction method includes the following steps:
step S401, when the terminal device obtains a pause playing instruction triggered by the user and used for instructing to pause the playing of the video stream, a timestamp when the user executes the operation of pausing the playing of the video is obtained. In specific implementation, when it is monitored that a user triggers a certain marking element, it is determined that the user triggers a pause playing instruction, and the playing of the video stream is paused in response to the pause playing instruction.
