It is to be understood that, in the above embodiments, the encoding mode of the second video stream or the third video stream of the shooting device may be an existing encoding mode, and the present invention is not described in detail again.
In addition, the external display device in the above embodiment may be a mobile terminal such as a mobile phone or a Pad, or may be another terminal device.
S302: storing the first video stream and the second video stream in a storage device;
in this embodiment, after the storage device obtains the first video stream and the second video stream, the storage device may directly or indirectly store the first video stream and the second video stream in the storage device. As in the above embodiments, the storage device may be an internal storage device of the photographing device, or an external storage device of the photographing device.
S303: when video playback is performed, one of the first video stream and the second video stream is selected to be played back through a display of the shooting device.
When video playback is performed, the shooting device can select one video stream from the first video stream and the second video stream to perform playback by adopting different strategies.
In one embodiment, the video stream to be played back is matched according to the display resolution of the display of the shooting device, so that the playback energy consumption is reduced as much as possible, and the requirement on the playing performance of the shooting device is reduced. The specific implementation process of S303 may include: and selecting one of the first video stream and the second video stream to be played back through the display of the shooting device according to the display resolution of the display of the shooting device. Optionally, if the display resolution of the display of the shooting device is less than or equal to the resolution of the second video stream, playing back the second video stream through the display of the shooting device to reduce playback energy consumption; and if the display resolution of the display of the shooting device is greater than that of the second video stream, playing back the first video stream through the display of the shooting device so as to obtain a better display effect.
In another embodiment, the video streams to be played back are matched according to the camera's battery level (the camera's real-time battery level). The specific implementation process of S303 may include: and selecting one video stream from the first video stream and the second video stream to be played back through a display of the shooting device according to the battery power of the shooting device. Optionally, if the battery power of the shooting device is higher than or equal to the preset power, the first video stream is played back through the display of the shooting device, so that a better display effect can be obtained when the display resolution of the display of the shooting device is greater than that of the second video stream; and if the battery electric quantity of the shooting device is lower than the preset electric quantity, the second video stream is played back through the display of the shooting device, so that the power consumption speed during playback is reduced, and the playback time length is prolonged.
The preset electric quantity can be a fixed value or a real-time updated and changed value.
As a possible implementation manner, the preset power may be a fixed size, such as the preset power is an empirical value, or the preset power is a minimum power required for playing back the first video stream.
As another possible implementation manner, the preset electric quantity is a value that changes in real-time updating, and the change manner of the size of the preset electric quantity depends on the size of the video stream. Optionally, the preset electric quantity is determined according to an electric quantity required for playing back the first video stream or an electric quantity required for playing back the second video stream, for example, when an electric quantity of a battery of the shooting device is greater than or equal to a minimum electric quantity required for playing back the first video stream, the preset electric quantity is the minimum electric quantity required for playing back the first video stream; when the battery power of the shooting device is smaller than the minimum power required for playing back the first video stream, the preset power is 0. Optionally, the preset electric quantity is determined according to other strategies, for example, the preset electric quantity is determined according to an expected playback time length, where the expected playback time length is set by a user.
Of course, it can be understood that, when one of the first video stream and the second video stream is selected to be played back through the display of the shooting device, the video playback strategy of the shooting device may also adopt other strategies besides the two strategies described above, so as to perform corresponding video playback according to the actual situation of the shooting device, and meet the requirements of the shooting device for lower video playback energy consumption or better display effect.
In the following embodiments, a video stream to be played back that is matched according to the display resolution of the display of the shooting device is referred to as a video playback policy 1, and a video stream to be played back that is matched according to the battery power of the shooting device is referred to as a video playback policy 2, if the shooting device has two video playback policies, namely the video playback policy 1 and the video playback policy 2, at the same time, in order to avoid a conflict when the shooting device performs video playback, in one embodiment, when the shooting device performs video playback, a user is required to select a video playback policy of the current video playback, and if the user selects the video playback policy 1 as the video playback policy of the current video playback, the shooting device matches the video stream to be played back according to the display resolution of the display of the shooting device; if the user selects the video playback strategy 2 as the video playback strategy of the current video playback, the shooting device matches the video stream to be played back according to the battery capacity of the shooting device.
In another embodiment, a conflict can be avoided when the cameras play back videos by setting priorities of two video playback strategies so that the cameras use one of the video playback strategies to match the video stream to be played back when playing back videos. As a possible implementation manner, the priority of the video playback policy 1 is higher than that of the video playback policy 2, so that when the shooting device performs video playback, the shooting device matches the video stream to be played back according to the size of the display resolution of the display of the shooting device. As another possible implementation, when the battery level of the photographing device is greater than or equal to a certain level, the priority of the video playback policy 1 is higher than that of the video playback policy 2; when the battery level of the photographing apparatus is less than a certain level, the priority of the video playback strategy 1 is lower than that of the video playback strategy 2. When the battery capacity of the shooting device is larger than or equal to a specific capacity, the shooting device matches the video stream to be played back according to the display resolution of the display of the shooting device; and when the battery capacity of the shooting device is less than the specific capacity, the shooting device matches the video stream to be played back according to the battery capacity of the shooting device. The specific amount of power may be an empirical value or the specific amount of power may be set by a user. Of course, the setting manner of the priority of the video playback policy of the photographing device is not limited to the above two manners, and the priority of the video playback policy of the photographing device may be set by other manners.
In another embodiment, the two video playback strategies can be combined to match the video stream to be played back, so as to fit the current actual situation of the shooting device as much as possible, and achieve a better playback effect. For example, when the display resolution of the display of the photographing device is greater than the second video stream and the battery power of the photographing device is greater than or equal to a preset power, the first video stream may be played back through the display of the photographing device, and after the battery power of the photographing device is less than the preset power, the second video stream may be played back through the display of the photographing device.
In one embodiment, after the video stream a to be played back is matched according to the battery power of the shooting device (the real-time battery power of the shooting device), if the display resolution of the display is greater than the resolution of the selected video stream a, and a video stream B exists in the storage device, where the resolution is higher than that of the video stream a and the obtained target object is the same as that of the video stream a, during the playback of the video stream a, the playback of the video stream a can be switched to the playback of the video stream B based on the operation of the user on the shooting device, so as to meet the requirement that the user needs to obtain a better display effect.
In one embodiment, when video playback is performed, when the shooting device selects one of the first video stream and the second video stream for playback, both the first video stream and the second video stream may not be displayed, so as to reduce selection interference to a user, and be beneficial to meeting requirements of the shooting device for low power consumption or display effect as much as possible. Thus, the specific implementation process of S303 may include:
1) displaying the first video stream on a playback interface of a display of the photographing apparatus;
in the step, a first video stream shot by the video recording device is displayed on the playback interface. That is, the second video stream may not be displayed. In this manner, the user does not need to select between the first video stream and the second video stream.
2) And when a video playback instruction for the first video stream is received, selecting one video stream from the first video stream and the second video stream to be played back through a display of the shooting device.
In this embodiment, when the shooting device receives a video playback instruction for the first video stream, one of the video streams is played back through the display of the shooting device. That is, even if it is a video playback instruction for the first video stream, it is possible to select the second video stream as the video stream to be played back and play back the second video stream. The video playback instruction can be generated by the user operating the corresponding key/knob of the shooting device, and can also be generated by the user operating the external control equipment. Of course, the video playback instruction may also be generated by the user through other operation modes, such as touch control, gestures, voice and the like.

When the external storage device is arranged on the second shooting device, the video stream in the external storage device is played back through a display of the second shooting device. Wherein the video playback policy of the second camera for the video stream in the external storage device is the same as the video playback policy of the first camera. That is, the video stream in the external storage device can be played back through the display of the first photographing device or the display of the second photographing device. Wherein the first camera and the second camera may be cameras of two versions of the same series of products of the same manufacturer to have the same video playback strategy.
