In embodiments, during video recording, since both the and second cameras are turned on for video recording, they each generate video images, i.e., video recordings generate two video files in total, the camera captured pictures forming the th video stream and the second camera captured pictures forming the second video stream.
In embodiments, the video recording may also obtain an audio stream for compositing with the th video stream and/or the second video stream such that the resulting video has corresponding audio, during the video recording, audio files and two video files are obtained at the same time period, the audio files and two video files may be independent, i.e., non-interfering, e.g., a microphone may be used to obtain the audio files, and video files may be obtained by and the second camera, respectively.
In embodiments, during video recording, the terminal may display the video stream obtained by the camera and the second video stream obtained by the second camera, for example, in the display screen of a cell phone when the terminal is a cell phone, in embodiments, displaying the th video stream and the second video stream simultaneously by the terminal may include determining display area information of the th video stream and the second video stream, and then displaying the th video stream in the region and the second video stream in the second region according to the display area information.
For example, as shown in FIG. 2, a th video stream 21 and a second video stream 22 are shown displayed in a picture-in-picture format, wherein the second video stream 22 occupies a portion of the picture in the th video stream 21, i.e., covers a portion of the picture in the th video stream 21. as shown in FIG. 3, a th video stream 21 and a second video stream 22 are shown displayed in a split-screen format, wherein a th video stream 21 and a second video stream 22 each occupy a portion of the display screen. in the embodiment, the th video stream 21 and the second video stream 22 are displayed in a split-screen format, the display areas of the th video stream 21 and the second video stream 22 may be the same or different in the embodiment, when displayed in a picture-in-picture-in-picture video format or in a split-in-screen format, ones of the th video stream 21 and the second video stream 22 may be larger than those of the th video stream 21 and the second video stream 22 in which of the display areas of the 3621 and the second video stream 22 are larger than those of the display areas of the 3622, which of the display areas of the 3621, the display areas of the second video stream 9622 may be set in the 3637, which of the second video stream 3621, which of the second video stream, which of the display areas of the display area of.
In embodiments, when the region is located within the second region (i.e., displayed in a picture-in-picture manner), the region may be located at the corner of the second region, or the region may be located in a region that has minimal impact on the content displayed by the second region. for example, in embodiments, when displayed in a picture-in-picture manner, the smaller image may be attached to four corners of the larger image, as shown in fig. 2, for example, in embodiments, the position of the smaller image is intelligently identified, i.e., the smaller image is attached to a position that has less impact on the display of the larger image, such as a position or blank position where people and scenery are less visible in the larger image.
In , during video recording, by displaying video stream and the second video stream simultaneously in the terminal, the content of the video obtained by the camera can be watched in time, which facilitates the user to select the shooting direction or content during video recording.
