The method of a kind of intercepting dynamic image provided by the present invention, as shown in Figure 1, mainly may further comprise the steps:
Client among the present invention can be the various terminal equipments that can carry out instant messaging; For example: personal computer (PC; Personal Computer), personal digital assistant (PDA, Personal Digital Assistant), mobile phone (MP, Mobile Phone) or the like.
The user uses IM instrument and good friend to carry out in the process of IM session on client, and simultaneously video file such as movie perhaps carries out Online Video; At this moment, if the user needs a splendid moment or a plurality of continuous action in the in progress video of intercepting, then can select corresponding video interception operation, to initiate the video interception request to client through the actions menu on the user interface.
It is to be noted; Splendid moment in the intercepting video if desired; Then the user can select the operation of moment of intercepting animation through actions menu, triggers client and gets into the intercepting animation operating process of moment, and in the video interception request of initiating, carry the time point of user's appointment; The time point of this appointment needs the animation residing position of moment of intercepting in order to the Spoke-to-Client end.In practical application, the user can utilize mouse to double-click the picture in the in progress video on the screen, needs the time point of animation moment of intercepting with acquisition.For example: the user needs the picture A in the intercepting video, then when video playback arrives picture A, utilizes mouse to double-click picture A, to obtain picture A time corresponding point.
A plurality of continuous actions in the intercepting video if desired; Then the user can select the operation of intercepting continuous animation through actions menu; Trigger the operating process that client gets into the intercepting continuous animation, and in the video interception request of initiating, carry the time period of user's appointment; The time period of this appointment needs the residing position range of continuous animation of intercepting in order to the Spoke-to-Client end.In practical application, the user can utilize mouse to double-click the picture in the in progress video on the screen for twice, needs the time period of the continuous animation of intercepting with acquisition.So-called twice double-click promptly is meant and double-clicks the start time point that mouse need to confirm the continuous animation of intercepting for the first time, double-clicks the concluding time point of continuous animation that need to confirm intercepting once more.For example: the user needs picture A and the continuous animation between the picture B in the intercepting video, then in video playback in the picture A, utilize mouse to double-click picture A, to obtain picture A time corresponding point (start time point); When video playback arrives picture B, utilize mouse to double-click picture B again, to obtain picture B time corresponding point (concluding time point).Thereby obtain the time period between picture A and the picture B through twice double-click.
If the user is the intercepting animation operating process of moment through the entering of actions menu triggering client, then client is carried out the intercepting animation operating process of moment according to the time point of appointment in preset configuration parameter and the video interception request; If what the user triggered the client entering is the operating process of intercepting continuous animation, then client is carried out the operating process of intercepting continuous animation according to the time period of appointment in preset configuration parameter and the video interception request.The operation of intercepting animation moment and intercepting continuous animation can realize through the mode of DirectX.
