In addition to the above-mentioned manner of simultaneously displaying the first video signal and the second video signal, those skilled in the art may also adopt other manners of simultaneously displaying the first video signal and the second video signal according to actual needs, which is not limited in this embodiment.
And S103, receiving a selection operation.
And S104, responding to the selection operation, and displaying the first video signal or the second video signal in the selected state.
In general, in order to prevent an erroneous operation, the first video signal and the second video signal are in a non-selected state during display, and at this time, the screen adjustment operation for the first video signal or the second video signal is invalid.
In the live broadcasting process, according to the live broadcasting requirement, for example, if the picture of the first video signal or the second video signal is small, which causes the content to be difficult to see clearly, the content in the region where the first video signal and the second video signal overlap is important, which prevents the audience user from watching, and so on, as shown in fig. 3A, the selection operation may be triggered by long press, touch double click, and so on, and the first video signal or the second video signal located below the selection operation is in the selected state, at this time, the picture adjustment operation for the first video signal or the second video signal is effective.
In a case where the first video signal is displayed in the first window and the second video signal is displayed in the second window, when it is determined that the first video signal is selected, it is determined that the first window is in a selected state, at which time, a picture adjustment operation for the first video signal may be applied to the first window, or, when it is determined that the second video signal is selected, it is determined that the second window is in a selected state, at which time, a picture adjustment operation for the second video signal may be applied to the second window.
In the case where the first video signal is synthesized in the first area of the target video signal and the second video signal is synthesized in the second area of the target video signal, it is determined that the first area is in a selected state when it is determined that the first video signal is selected, and at this time, the picture-adjusting operation for the first video signal may be applied to the first area, or it is determined that the second area is in a selected state when it is determined that the second video signal is selected, and at this time, the picture-adjusting operation for the second video signal may be applied to the second area.
For the case where the first video signal and the second video signal under the selected operation overlap, the first video signal is in the selected state if the first video signal is on the second video signal, and the second video signal is in the selected state if the second video signal is on the first video signal.
As shown in fig. 3B, for the first video signal or the second video signal in the selected state, identification information may be displayed to identify that the first video signal or the second video signal is in the selected state, for example, a frame is displayed around the first video signal or the second video signal, a cross pattern is displayed in the first video signal or the second video signal, and so on.
And S105, receiving the picture adjusting operation.
And S106, displaying the adjustment of the first video signal or the second video signal in the selected state according to the picture adjustment operation.
After the first video signal or the second video signal is selected, picture adjusting operation is triggered through gestures, controls and the like, the selected first video signal or the selected second video signal is correspondingly adjusted, and therefore the adjustment is displayed on the display screen.
If the first video signal is displayed in the first window and the second video signal is displayed in the second window, at this time, the first window or the second window can be adjusted according to the picture adjusting operation so as to adjust the first video signal or the second video signal in the selected state.
If the first video signal is synthesized in the first area of the target video signal and the second video signal is synthesized in the second area of the target video signal, the first area or the second area can be adjusted according to the picture adjusting operation to adjust the first video signal or the second video signal in the selected state.
In order to make those skilled in the art better understand the present embodiment, the following uses gestures as a specific example to illustrate the adjustment of the first video signal or the second video signal in the present embodiment.
In this embodiment, the screen adjustment operation includes at least one of the following gestures:
1. drag gesture
The drag gesture may refer to a simultaneous sliding of the object (the first video signal or the second video signal) while being pressed.
If a drag gesture is detected in the touch screen, the first video signal or the second video signal in the selected state can be dragged according to the drag gesture.
For example, as shown in fig. 4A, a video signal in a small area in the pip mode is set as a first video signal, and a finger of a host user presses the first video signal and slides to the left, as shown in fig. 4B, a process that the display screen can display the first video signal and slide to the left is displayed, and when the host user lifts the finger, the first video signal stops sliding.
Further, a dragging direction of the dragging gesture can be determined, and the dragging gesture is mapped to a dragging distance in the dragging direction according to a certain functional relation, at this time, the first video signal or the second video signal in the selected state can be dragged in the dragging direction until the dragging distance is reached.
For the situation that the first video signal is displayed in the first window and the second video signal is displayed in the second window, the first window to which the first video signal in the selected state belongs can be dragged according to the dragging gesture to realize dragging of the first video signal, or the second window to which the second video signal in the selected state belongs can be dragged according to the dragging gesture to realize dragging of the second video signal.
For the situation that the first video signal is synthesized in the first area of the target video signal and the second video signal is synthesized in the second area of the target video signal, the first area corresponding to the first video signal in the selected state can be dragged according to the dragging gesture, the first video signal is drawn in the first area after dragging, and the dragging of the first video signal is realized, or the second area corresponding to the second video signal in the selected state can be dragged according to the dragging gesture, and the second video signal is drawn in the second area after dragging, and the dragging of the second video signal is realized.
2. Zoom gesture
The zoom gesture may refer to a gathering (zooming-out) or a spreading (zooming-in) of the plurality of touch points with the target (the first video signal or the second video signal) as a base point.
If a zoom gesture is detected in the touch screen, the first video signal or the second video signal in the selected state may be zoomed according to the zoom gesture.
For example, as shown in fig. 4C, a video signal in a small area in the pip mode is set as a first video signal, and two fingers of the anchor user press the first video signal and spread the first video signal outward, as shown in fig. 4D, the process of amplifying the first video signal can be displayed on the display screen, and the first video signal stops being amplified when the anchor user lifts the fingers.
Further, the scaling gesture may be mapped to a scaling according to a function, and at this time, the first video signal or the second video signal in the selected state may be scaled according to the scaling.
For the situation that the first video signal is displayed in the first window and the second video signal is displayed in the second window, the first window to which the first video signal in the selected state belongs may be zoomed according to the zoom gesture to achieve zooming of the first video signal, or the second window to which the second video signal in the selected state belongs may be zoomed according to the zoom gesture to achieve zooming of the second video signal.
For the case that the first video signal is synthesized in the first region of the target video signal and the second video signal is synthesized in the second region of the target video signal, the first region corresponding to the first video signal in the selected state may be zoomed according to the zoom gesture, the first video signal is drawn in the first region after the zoom, and the zoom of the first video signal is realized, or the second region corresponding to the second video signal in the selected state may be zoomed according to the zoom gesture, the second video signal is drawn in the second region after the zoom, and the zoom of the second video signal is realized.
3. Rotational gestures
The rotation gesture may refer to a rotation of the plurality of touch points with the object (the first video signal or the second video signal) as a base point.
If a rotation gesture is detected in the touch screen, the first video signal or the second video signal in the selected state may be rotated according to the rotation gesture.
For example, as shown in fig. 4E, the video signal in the small area in the pip mode is set as the first video signal, and two fingers of the anchor user press down the first video signal and rotate clockwise, as shown in fig. 4F, a process that the display screen can display the clockwise rotation of the first video signal is displayed, and the clockwise rotation of the first video signal is stopped when the anchor user lifts up the fingers.
Further, the rotation gesture may be mapped to a rotation angle according to a certain functional relation, and at this time, the first video signal or the second video signal in the selected state may be rotated according to the rotation angle.
For the situation that the first video signal is displayed in the first window and the second video signal is displayed in the second window, the first window to which the first video signal in the selected state belongs may be rotated according to the rotation gesture to realize the rotation of the first video signal, or the second window to which the second video signal in the selected state belongs may be rotated according to the rotation gesture to realize the rotation of the second video signal.
For the case that the first video signal is synthesized in the first area of the target video signal and the second video signal is synthesized in the second area of the target video signal, the first area corresponding to the first video signal in the selected state may be rotated according to the rotation gesture, and the first video signal may be drawn in the first area after scaling, so as to implement the rotation of the first video signal, or the second area corresponding to the second video signal in the selected state may be rotated according to the rotation gesture, and the second video signal may be drawn in the second area after rotation, so as to implement the rotation of the second video signal.
Of course, the above-mentioned screen adjustment operation is only an example, and when the present embodiment is implemented, other screen adjustment operations may be set according to actual situations, which is not limited in the present embodiment. In addition, besides the above-mentioned picture adjusting operation, a person skilled in the art may also adopt other picture adjusting operations according to actual needs, which is not limited in this embodiment.
In this embodiment, a live preview operation is received, a first video signal from a first camera and a second video signal from a second camera are displayed in response to the preview operation, a selection operation is received, the first video signal or the second video signal in a selected state is displayed in response to the selection operation, a picture adjustment operation is received, and an adjustment of the first video signal or the second video signal in the selected state is displayed according to the picture adjustment operation, on one hand, live broadcast is performed by using the two cameras simultaneously, video signals can be collected simultaneously for two objects, a host user can conveniently adjust the video signal and a scene, loss of a live broadcast picture is avoided, on the other hand, the host user can dynamically adjust the first video signal and the second video signal, and the display modes are fixed relative to a picture-in-picture mode, a top-bottom mode, a left-right mode and the like, the form of autonomic adjustment is various, and the flexibility is strong, and the anchor user can be better with the live content of the laminating of live picture, guarantees live effect.
Example two
Fig. 5 is a flowchart of a live broadcast method according to a second embodiment of the present invention, where the present embodiment further adds a processing operation of starting a camera based on the foregoing embodiment, and the method specifically includes the following steps:
s501, receiving live preview operation.
And S502, responding to the preview operation, and starting the first camera or the second camera.
The first camera is configured to acquire a first video signal conforming to a first video parameter (e.g., a first resolution, a first frame rate, a first focus parameter, etc.).
The second camera is used for acquiring a second video signal which accords with a second video parameter (such as a second resolution, a second frame rate, a second focusing parameter and the like).
S503, when the first camera or the second camera is started, starting the second camera or the first camera.
In this embodiment, when a host user triggers a preview operation of live broadcast, a live broadcast Application may call an Application Programming Interface (API) provided by an operating system, start a first camera using a preset first video parameter, and the first camera acquires a first video signal conforming to the first video parameter.
If the first camera is started first, the live broadcast application can call the API provided by the operating system when the first camera is started, the preset second video parameter is used for starting the second camera, and the second camera acquires a second video signal which is in accordance with the second video parameter.
If the second camera is started first, when the second camera is started, the live broadcast application can call the API provided by the operating system, the preset first video parameter is used for starting the first camera, and the first camera acquires the first video signal which is in accordance with the first video parameter.
For example, in Android, a camera authority is newly added to an Android main file, two surfeviews are set, a camera is acquired by a call method camera getnumberofcameras (), a camera preview is started by a call method startPreview (), a first camera preview is initialized, a first video parameter of the first camera is initialized, and a method setDisplayOrientation () is called to control a correct display direction of a first video signal, and a correct display of the first video signal is realized, an error is reported when an error is displayed, and likewise, a camera is acquired by a call method camera getnumberofcameras (), a second camera is started by a call method startPreview (), a second video parameter of the second camera is initialized, and a setDisplayOrientation () is called to control a correct display direction of the second video signal, and a correct display of the second video signal is realized, an error is reported when an error is displayed.
In a specific implementation, when two cameras are simultaneously started in the same application (live application), when a first camera is started, the authority of the first camera (i.e., the first camera or the second camera) is preempted, so that the first camera (i.e., the first camera or the second camera) can be normally started, and the authority of a second camera (i.e., the second camera or the first camera) is not preempted, so that the second camera (i.e., the second camera or the first camera) may be occupied by other applications and cause a start failure.
If so, the second camera (i.e., the second camera or the first camera) is turned off, the second camera (i.e., the second camera or the first camera) is released, and the second camera (i.e., the second camera or the first camera) is turned on.
If not, the second camera (namely the second camera or the first camera) is started.

If the orientation of the second camera (e.g., front camera) is the same as that of the display screen and the orientation of the first camera (e.g., rear camera) is different from that of the display screen, the first image processing and the second image processing may be performed on the second video signal, and the second image processing may be performed on the first video signal.
In the case where the first video signal is combined in a first area of the target video signal and the second video signal is combined in a second area of the target video signal, if the first camera (e.g., a front camera) and the display screen are oriented in the same direction and the second camera (e.g., a rear camera) and the display screen are oriented in different directions, the first image processing is performed on the first video signal and the second image processing is performed on the target video signal.
If the orientation of the second camera (such as a front camera) is the same as that of the display screen and the orientation of the first camera (such as a rear camera) is different from that of the display screen, the first image processing is performed on the second video signal, and the second image processing is performed on the target video signal.
S605, receiving the screen switching operation.
And S606, responding to the picture switching operation, and switching the first video signal and the second video signal.
