Wherein, before the step of the one or more videos of described demonstration, determine predeterminated position and default size and frequency.
Wherein, picture frame, audio frame and video file are stored in the memory.
Wherein, in a plurality of videos, comprise a near-end conversation video and one or more far-end conversation video.
Wherein, described size is at least one in pixel size and the picture size size.
In addition, the invention allows for the generating apparatus of video file in a kind of video calling, comprising: display module is used for showing one or more video files on the predeterminated position of screen; The screenshotss module is used for default size and frequency one or more video files being carried out screenshotss, to generate a plurality of picture frames; And synthesis module, be used for a plurality of picture frames and synchronous with it audio frame are synthesized video file.
Wherein, this device also comprises module is set, and is used for determining predeterminated position and default size and frequency.
Wherein, this device also comprises memory module, is used for storing respectively a plurality of picture frames and audio frame, and synthetic video file.
Wherein, in a plurality of videos, comprise a near-end conversation video and one or more far-end conversation video.
Wherein, described size is at least one in pixel size and the picture size size.
Beneficial effect of the present invention is: adopt the method and apparatus that discloses among the present invention, can on a screen, record both sides or a plurality of video calls, and can adjust the size of the video of each side in the video recording to the requirement of recording definition according to the user, and the screenshotss frequency of the demand of recording image quality being adjusted the screenshotss process according to the user, thereby more reasonably optimize the recording process of video call, utilized communication and storage resources more fully.

Embodiment
Describe below in conjunction with the generation method and apparatus of accompanying drawing video file in the video calling.
Fig. 1 is the flow chart of the method according to this invention, and visual telephone service realizes that the function of automatic answering machine may further comprise the steps:
Step 101: will need one or more video file of synthesizing to refresh and be presented on the screen according to default position;
Step 102: come screenshotss generation picture frame here, according to default screenshotss size (" size " expression but be not limited to the meaning of pixel size as required, can be to carrying out screenshotss within the specific dimensions of screen) and screenshotss frequency;
Step 103: with the picture frame that obtains and the final video file of the synthetic generation of corresponding audio frame synchronization with it, wherein, except in communication process, video file being generated synchronously, can also store all picture frame and audio frame earlier, afterwards, if the user has selected to carry out the instruction of synthetic video file, then picture frame and audio frame are synthesized, if and the user does not plan to synthesize, then can select to continue to preserve or abandon above-mentioned picture frame and audio frame.
Fig. 2 is the flow chart synthetic according to the video of two-way video recording in the video telephone of exemplary embodiment of the present invention, and it uses step to comprise:
Step 201: record a video in the conversation on video telephone;
Step 202: distal view picture and near-end image all refreshed be presented on the screen;
Step 203: come screenshotss according to the screenshotss size of setting and the frequency of screenshotss;
Step 204: the picture frame that screenshotss are generated is stored in the internal memory, and the audio frame with corresponding this picture frame also is stored in the internal memory simultaneously;
Step 205: picture frame in the internal memory and audio frame are synthesized new frame of video and preserved;
Wherein, it is prior art that picture frame and audio frame are synthesized, not within limit of consideration of the present invention;
