Referring to fig. 4, fig. 4 is a flowchart illustrating a video processing method according to another embodiment of the present application. Referring to fig. 5, the electronic device 100 includes a Processor 110 and a frame insertion chip 130, wherein the Processor 110 may be an Application Processor (AP), i.e., a Central Processing Unit (CPU), a Graphics Processing Unit (GPU), and the like.

As will be described in detail with respect to the flow shown in fig. 4, the video processing method may specifically include the following steps:
step S210: and transmitting the video to be processed to the frame insertion chip through the application program processor.
In the embodiment of the application, when the video to be processed is subjected to the frame interpolation processing, the application processor may transmit the video data of the video to be processed to the frame interpolation chip after obtaining the video to be processed to be subjected to the frame interpolation processing, so that the frame interpolation chip performs the frame interpolation processing on the video to be processed to be subjected to the frame interpolation processing.

In the embodiment of the application, after the frame interpolation is performed on the video to be processed, the frame interpolation chip can add the specified identifier to the video to be processed after the frame interpolation processing, so as to obtain the target video carrying the specified identifier. In some embodiments, because the storage capacity of the storage unit of the frame interpolation chip is limited and each frame of image of the video cannot be completely stored, when the frame interpolation chip outputs one frame of image to the display screen, a designated identifier is added to the frame of image, then each frame of image is transmitted to the application program processor, and a plurality of frames of images carrying the designated identifier received by the application program processor can form a complete target video.
In some embodiments, referring to fig. 6, the frame interpolation chip includes a frame interpolation processing unit 136, an output control unit 135, a storage control unit 133, and a storage unit 134. The frame interpolation processing unit 136 is configured to perform frame interpolation processing on the video and add a specified identifier to the video after the frame interpolation processing, so as to obtain a target video; the output control unit 135 is used for controlling the output of data in the frame insertion chip, for example, to a display screen or the like; the storage unit 135 is used for storing data in the process of processing the input video data by the frame insertion chip; the storage control unit 133 is used to implement storage control, and can implement reading and writing of data from the storage unit 134. Of course, other units, such as the input control unit 131, the compression processing unit 132, and the like shown in fig. 6, are also included in the frame interpolation chip 130.
In the frame interpolation chip shown in fig. 6, since only the compression processing unit 132 is connected to the storage control unit, the output control unit 133 cannot retrieve image data of a video after frame interpolation. Therefore, referring to fig. 7, the frame interpolation chip 130 may be modified to add a path between the output control unit 135 and the storage control unit, so that the frame interpolation processing unit 136 may store each frame image of the video after frame interpolation in the storage unit 134, and then the output control unit 135 reads each frame image from the storage unit 134 by using the added path. Specifically, each frame image of the target video is transmitted to the storage control unit 133 through the frame interpolation processing unit 136; storing each frame image of the target video to the storage unit 134 through the storage control unit 133; each frame image of the target video is read from the storage unit through the output control unit 135 and transmitted to the processor 110. Therefore, through the mode, the frame insertion chip can add the designated identification to the video subjected to frame insertion and transmit the designated identification back to the application program processor, and the application program processor can subsequently upload the target video to the server through the corresponding network service interface.
Step S250: uploading, by the application processor, the target video to a server.
According to the video processing method provided by the embodiment of the application, when the video to be processed is subjected to frame insertion processing through the frame insertion chip, the frame insertion chip identifies the video to be processed after frame insertion and transmits the video back to the application program processor, and the application program processor uploads the target video to the server through the corresponding network service interface, so that the video after frame insertion processing of the electronic equipment can be shared, the specified identification is added to the video after frame insertion, other equipment can acquire the target video from the server, and the video after frame insertion can be directly played according to the specified identification in the target video.
Referring to fig. 8, fig. 8 is a flow chart illustrating a video processing method according to another embodiment of the present application. The video processing method is applied to the electronic device, and will be described in detail with respect to the flow shown in fig. 8, and the video processing method may specifically include the following steps:
step S310: and acquiring the video for playing from the server as the video to be processed.
In this embodiment of the application, the frame interpolation performed by the electronic device on the video to be processed may be a scene used for video playing, and first, the electronic device may obtain the video for playing. Specifically, the electronic device may obtain a video for playback from a server. The server may be a server to which the target video is uploaded, and is configured to manage the video, and in the stored video, the video subjected to the frame insertion processing may carry a specified identifier.
Step S320: and judging whether the video to be processed carries the specified identification.
In the embodiment of the application, after the electronic device acquires the video to be processed from the server, whether the video to be processed carries the specified identifier or not can be judged. If the video to be processed carries the designated identification, the video to be processed is indicated to be subjected to frame interpolation processing; and if the video to be processed does not carry the specified identifier, indicating that the video to be processed does not carry out frame interpolation processing.
Step S330: and when the video to be processed does not carry the designated identification, performing frame insertion processing on the video in the process of playing the video.
In this embodiment of the application, when the electronic device determines that the to-be-processed video does not carry the designated identifier, it indicates that the to-be-processed video is not subjected to frame interpolation processing.
Step S340: and when the video to be processed carries the specified identification, acquiring the frame rate of the video.
Step S350: and when the frame rate is lower than a preset frame rate, performing frame interpolation processing on the video to be processed in the process of playing the video to be processed, wherein the frame rate of the video subjected to frame interpolation processing is greater than or equal to the preset frame rate.
In this embodiment of the application, when the electronic device determines that the video to be processed carries the specified identifier, it indicates that the video to be processed is subjected to frame interpolation processing, and in this case, the electronic device may determine whether further frame interpolation processing needs to be performed on the video to be processed, so as to improve the frame rate of the video to be processed.
In this embodiment of the application, when it is determined that the video to be processed carries the specified identifier, the electronic device may obtain a frame rate of the video to be processed, compare the frame rate with a preset frame rate, and if the frame rate is greater than or equal to the preset frame rate, it indicates that the frame rate of the video to be processed is higher, that is, the video to be processed is good in fluency, and therefore, it is not necessary to perform frame interpolation again, which causes resource waste; if the frame rate is the first preset frame rate, the electronic device can perform frame interpolation processing on the video to be processed so as to further improve the frame rate of the video to be processed, so that the frame rate reaches the preset frame rate, and the playing effect of the video to be processed is further improved. The preset frame rate may be determined according to a highest frame rate that the electronic device can achieve by frame interpolation, and specifically, the preset frame rate may be less than the highest frame rate.
In some embodiments, when the electronic device performs video playing, in the process of inserting frames into a video to be processed, a change of a video playing interface may be detected, and when it is detected that the video playing interface is displaced in the same direction, for example, a playing area of a current video slides in a direction, and a playing area of a next video is gradually exposed until the video playing interface is displayed in a middle area, in this case, the frame insertion processing may be suspended, so as to avoid that, when the video playing interface is displaced, a frame rate of a dynamic change effect of the displacement is rendered at the same time, and the frame rate is inconsistent with a video frame rate after the frame insertion, and display abnormalities such as edge cracks, shadows, and jams occur. Specifically, the electronic device may detect a motion vector of a preset detection point on an edge of the video playing area, where the motion vector of the preset detection point represents a displacement of a pixel point, and a direction and a magnitude of the motion vector may reflect a direction and a speed of the displacement of the pixel point. The preset detection point may be a pixel point on the edge of the video playing area, and the specific position thereof may not be defined. It can be understood that, when the above video playing application performs video switching, the video area moves, so that other areas in the interface also change until the video playing area corresponding to the next video is completely exposed and displayed to the corresponding position in the interface. When the video area moves, the edge is representative, that is, the video playing area moves, and the boundary of the video playing area must move in the same direction, so that the pixel point on the edge in the video playing area can be used as a preset detection point. The number of the preset detection points may not be limited, and may be at least two, for example, 2, or 3. If the motion vectors of each preset detection point are the same, the video playing area is indicated to move towards the same direction, namely the display condition of the interface change effect occurs during video switching, and at the moment, the frame insertion processing can be suspended, so that abnormal display is avoided.
