All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a flowchart of steps of a video processing method provided by an embodiment of the present invention, where the method may be applied to a first electronic device, and as shown in fig. 1, the method may include:
step 101, receiving a first input of at least one candidate video frame of a target video from a first electronic device user.
In the embodiment of the present invention, the target video may be a video that needs to be shared, the target video may be a video downloaded by a user from a network, or a video shot by the user through a first electronic device, the candidate video frames may be all video frames included in the target video, or may also be partial video frames included in the target video, and accordingly, the first electronic device may use the video frames in the target video as the candidate video frames. The first input may be performed by a user of the first electronic device when the user wants to encrypt video frames contained in the target video. For example, the first input may be a click input or a long-press input, and the like, which is not limited by the embodiment of the present invention.
Step 102, in response to the first input, marking N target video frames.
In this embodiment of the present invention, N may be a positive integer, and the target video frame may be a video frame that needs to be encrypted in a subsequent step selected from the candidate video frames, specifically, a user may send a first input to the first electronic device when wanting to encrypt a certain candidate video frame, and accordingly, the first electronic device may mark the target video frame from at least one frame of the candidate video frames according to the first input, for example, may use the candidate video frame selected by the first input as the target video frame.
And step 103, acquiring the encryption information input by the user.
In this embodiment of the present invention, the encryption information may be information for encrypting a target video frame, and the encryption information may be information of an image type capable of representing a shape, or information of a number or a character type, which is not limited in this embodiment of the present invention. Specifically, the first electronic device may display an encrypted information input interface after determining the target video frame, so as to facilitate a user to input encrypted information, and accordingly, the first electronic device may detect and receive an operation of the user on the input interface, so as to obtain the encrypted information.
And 104, encrypting the N target video frames based on the encryption information.
In the embodiment of the invention, the first electronic device can encrypt the image data of the target video frame by using the encryption information, so that the encrypted target video carries the encryption information and the encrypted target video frame, and the target video frame is played in a subsequent process in a state of successful decryption, so that the second electronic device can watch the video frames after the user of the second electronic device completes decryption by using the corresponding decryption information, and the sharing safety can be further improved to a certain extent.
Meanwhile, compared with a mode of directly encrypting the whole video, the embodiment of the invention can encrypt the video frame which needs to be encrypted by the user based on the selection operation of the first electronic equipment user on the candidate video frame, so that the encryption operation is more flexible, and meanwhile, only part of the video frame is encrypted, so that after sharing, the second terminal user can watch the unencrypted video frame part of the video without executing decryption operation, and further the playing efficiency is ensured to a certain extent.
And 105, sending the encrypted target video to second electronic equipment.
In the embodiment of the present invention, the second electronic device may be an electronic device having a friend relationship with the first electronic device, for example, the friend relationship may be established through social software of a third party, and specifically, when sending the encrypted target video to the second electronic device, identifiers of all friends having a friend relationship with the first electronic device may be displayed first, then, the electronic device corresponding to the identifier selected by the user is used as the second electronic device, and finally, the encrypted target video is sent to the second electronic device, so as to implement video sharing.
In summary, in the video processing method provided in the embodiments of the present invention, the first electronic device receives a first input of a user of the first electronic device to at least one candidate video frame of the target video, then, in response to the first input, marks N target video frames, obtains encryption information input by the user, encrypts the N target video frames based on the encryption information, and finally, sends the encrypted target video to the second electronic device. Compared with a mode of directly sharing the video for part of users and sharing the video after cutting the video for part of users, in the embodiment of the invention, the second electronic equipment user can watch all contents of the target video or only part of the contents in the target video based on the decryption information only by encrypting part of target video frames in the target video, so that the convenience degree of the sharing operation can be improved to a certain extent, and the time consumption of the sharing operation is reduced.
Fig. 2 is a flowchart of steps of a video processing method provided by an embodiment of the present invention, which may be applied to a second electronic device, as shown in fig. 2, and the method may include:
step 201, receiving a target video sent by a first electronic device, where the target video includes N target video frames, and the N target video frames are video frames encrypted based on encryption information input by a user of the first electronic device.
In this embodiment of the present invention, the target video frame may be a partial video frame in the target video, and the encryption information may be set by the user of the first electronic device.
Step 202, acquiring decryption information input by a user of the second electronic device.
In this embodiment of the present invention, the decryption information may be input by the user of the second electronic device when the user needs to play the visual video frame in the target video. Specifically, the second electronic device may consider that the second electronic device user needs to play the visual audio frame when receiving the first play operation, and accordingly, the second electronic device may obtain the decryption information. For example, the first play operation may be a long press operation on the target video.
And 203, playing the target video under the condition that the decryption information is matched with the encryption information, and playing the N target video frames in the playing process of the target video.
In the embodiment of the present invention, the target video may be played first, so that the second electronic device user can watch the target video as soon as possible, and meanwhile, it may be determined whether the encrypted target video frame can be played for the second electronic device user based on the decryption information, specifically, if the decryption information matches the encryption information, it indicates that the second electronic device user wants to watch the encrypted target video frame and has a watching qualification, so that the target video frame may be played in the playing process of the target video.
In summary, in the video processing method provided in the embodiment of the present invention, a second electronic device receives a target video sent by a first electronic device, where the target video includes N target video frames, where the N target video frames are video frames encrypted based on encryption information input by a user of the first electronic device, obtains decryption information input by the user of the second electronic device, and plays the target video and the N target video frames in a playing process of the target video when the decryption information matches the encryption information. Therefore, the first electronic device only needs to encrypt part of target video frames in the target view, and a user of the second electronic device can watch all contents of the target video or only part of contents in the target video based on decryption information, so that convenience degree of sharing operation can be improved to a certain extent, and time consumption of the sharing operation is reduced.
Fig. 3-1 is a flowchart illustrating steps of a video processing method according to an embodiment of the present invention, and as shown in fig. 3-1, the method may include:
step 301, a first electronic device receives a first input of at least one candidate video frame of a target video from a user of the first electronic device.
In this step, the first electronic device may receive a second input from the user of the first electronic device before receiving the first input, and then display at least one candidate video frame included in the target video in response to the second input. Wherein the second input may be a click input, a long press input, etc., and the second input may also be a second operation, such as a click operation, a long press operation, etc.,
further, if the first electronic device receives the second input, it may be considered that the user of the first electronic device needs to encrypt a part of the video frames, and accordingly, at least one candidate video frame included in the target video may be displayed. Therefore, the candidate video frames are displayed, so that the first electronic equipment user can more visually see the content of the video frames, the first electronic equipment user can conveniently select the video frames, and the selection convenience is improved.
Specifically, the first electronic device may implement displaying at least one candidate video frame included in the target video through the following steps 3011 to 3013:
step 3011, the first electronic device extracts a video key frame included in the target video.
In this step, since the number of video frames included in the video is often large and there are many video frames with similar contents, if all the video frames are used as candidate video frames, it may cause too many candidate video frames to be displayed and the repeatability is high, which further causes interference to the selection of the user and reduces the selection efficiency of the user.
Step 3012, determining at least one candidate video frame based on the video key frame.
In this step, the video key frame is also referred to as an I frame, which indicates a frame image that can be independently decoded and rendered without referring to other information, and the video key frame includes more abundant image information than other types of video frames.
Further, in determining candidate video frames based on the video key frames, the first electronic device may determine all of the video key frames as candidate video frames to provide a richer choice for the first electronic device user. Of course, the first electronic device may also select a target video key frame from the video key frames as a candidate video frame. The target object in the target video key frame is changed compared with the target object in the adjacent video key frame of the target video key frame; the target object includes at least one of a scene and a video object. The video object may be a character and an object appearing in the video, for example, the object may be a puppy, a kitten, a desk, a television, and so forth.
Specifically, the first electronic device may perform scene detection on each video key frame by using a preset scene recognition algorithm to determine a scene corresponding to each video key frame, and/or perform object recognition on each video key frame by using a preset object recognition algorithm to determine a video object corresponding to each video key frame, then compare the scenes corresponding to each video key frame to determine a video key frame with a scene change, and/or compare the video objects corresponding to each video key frame to determine a video key frame with a video object change, for example, a corresponding character moves, or a new character is added, or a video key frame of a character is reduced compared with other video key frames, and finally determine the video key frames as candidate video frames. In this way, the video key frames with changed scenes and/or changed video objects are selected from the video key frames to serve as candidate video frames, so that the displayed candidate video frames can be further reduced, and meanwhile, the video key frames with changed scenes and/or changed video objects are used as the candidate video frames, so that the image contents of the candidate video frames are more representative, and the representativeness of the target video frame selected from the candidate video frames is improved to a certain extent.
Step 3013, the first electronic device displays each candidate video frame according to the playing sequence of each candidate video frame in the target video.
In this step, the playing sequence of the candidate video frames in the target video may be the playing time point of the candidate video frames in the target video, and for example, it is assumed that there are 3 candidate video frames: the candidate video frames a, b and c are displayed by the first electronic device in the order of candidate video frame b, candidate video frame c and candidate video frame a, wherein the playing time point of candidate video frame b in the target video is 20 seconds at 3 minutes, the playing time point of candidate video frame c in the target video is 40 seconds at 3 minutes, and the playing time point of candidate video frame a in the target video is 50 seconds at 3 minutes. Therefore, the candidate video frames are displayed according to the playing sequence, so that the sequence of the displayed candidate video frames is more in line with the watching habit of the user, and the user can conveniently select the candidate video frames. Of course, the candidate video frames may also be randomly arranged, which is not limited in the embodiment of the present invention.
For example, fig. 3-2 is a schematic diagram of a user interface provided by an embodiment of the present invention, as shown in fig. 3-2, in which a target video 01 is displayed, and further, fig. 3-3 is a schematic diagram of another user interface provided by an embodiment of the present invention, which may be a user interface displayed by the first electronic device after receiving a second input, for example, after receiving a long press input of the user on the target video 01 in fig. 3-2, as shown in fig. 3-3, in which a plurality of candidate video frames 02 are displayed.
Of course, in another alternative embodiment of the present invention, when displaying the candidate video frames, the first electronic device may also directly use all video frames included in the target video as the candidate video frames, for example, assuming that the target video includes 100 video frames, the first electronic device may determine the 100 video frames as the candidate video frames, which is not limited in this embodiment of the present invention. Therefore, all the video frames are used as candidate video frames, the selectivity of the user can be improved to the maximum extent, and the selection effect is further ensured to a certain extent.
Step 302, the first electronic device marks N target video frames in response to the first input.
In this step, the first electronic device may first determine a candidate video frame selected by the first input.
Specifically, the first input may include a sliding input on the first candidate video frame, and accordingly, the determining of the candidate video frame selected by the first input may be implemented by the following sub-step (1):
substep (1): and the first electronic equipment determines the first candidate video frame as the candidate video frame selected by the first input under the condition that the sliding direction of the sliding input is a preset direction.
In this step, the preset direction may be preset according to an actual requirement, for example, the preset direction may be a horizontal direction from left to right, or a horizontal direction from right to left, which is not limited in this embodiment of the present invention. The first candidate video frame may be a video frame through which the slide input slides. Accordingly, the first electronic device takes the first candidate video frame selected by the slide input as the candidate video frame. Therefore, the first electronic equipment user can select the selected candidate video frame only by executing sliding input, the whole operation is high in convenience and low in implementation difficulty.
Further, in an actual application scene, in order to facilitate a user to acquire which candidate video frames have been selected as target video frames, the display form of the candidate video frames may be set to a preset form after the candidate video frames are determined as the target video frames, so that the user can conveniently distinguish whether the candidate video frames have been selected, and further, the selection efficiency of the user is improved. The preset form may be preset according to actual conditions, for example, the preset form may be a semi-transparent form, and accordingly, the first electronic device may set the display form of the candidate video frame to be the semi-transparent form. For example, fig. 3-4 are schematic diagrams of still another user interface provided by the embodiment of the invention, and as shown in fig. 3-4, the display form of the selected candidate video frame is changed into a semi-transparent form (the semi-transparent form is shown by covering with oblique lines in the figure). Further, when a viewing operation sent by the user is received, the candidate video frame indicated by the viewing operation may be displayed in an enlarged manner so as to facilitate the user to view, where the viewing operation may be a sliding operation on the candidate video frame, for example, the user may slide the candidate video frame left and right to control the first electronic device to display different candidate video frames in an enlarged manner. Accordingly, a snippet consisting of the selected candidate video frame and the associated non-video keyframes may also be played in the interface.
Further, the first electronic device may also determine a candidate video frame selected by the first input through the following sub-steps (2) to (4):
substep (2): displaying a selection control on the at least one candidate video frame.
In this step, at least one candidate video frame may constitute a candidate video frame sequence, and accordingly, the first electronic device may display a selection control on the candidate video frame sequence. For example, the image sequence composed of the plurality of candidate video frames at the bottom in fig. 3-3 is a candidate video frame sequence. Specifically, when the user selects, the user often performs the first input at the position that needs to be selected, so that the first electronic device may display the selection control at the operation position of the first input, so as to facilitate the user to perform the operation. Further, the selection control may be a selection sliding bar, and accordingly, the user may select the candidate video frame by moving the selection sliding bar, but of course, the selection control may also be other forms of controls, for example, a selection cursor including a start cursor and an end cursor, which is not limited in this embodiment of the present invention.
Substep (3): receiving a third input to the selection control by the first electronic device user.
In this step, the third input may be a click input, a long-press input, a slide input, or the like. The first electronic device user may effect the control selection control by performing a third input.
Substep (4): in response to the third input, a first position and a second position indicated by the third input are obtained.
Specifically, the first electronic device may determine a display position of the selection control as a first position, and after the third input is performed, the termination position of the selection control is determined as a second position, for example, taking the selection control as a selection sliding rod, a user may select the selection sliding rod and drag the selection sliding rod to implement the third input on the selection control, so that by performing the third input, the selection range of the selection control may be quickly adjusted, and then candidate video frames are continuously selected, so as to improve the selection efficiency. By way of example, taking the selection control as an example of a selection slider bar, fig. 3-5 are schematic diagrams of still another user interface provided by the embodiment of the present invention, and as shown in fig. 3-5, the selection slider bar is slid to the 7 th candidate video frame displayed.
Substep (4): determining candidate video frames between the first location and the second location as candidate video frames selected by the first input.
In this step, the candidate video frame between the first position and the second position is the candidate video pin that the user wants to select, so the first electronic device can determine the candidate video pin between the first position and the second position as the target video frame. In the embodiment of the invention, the selection control is displayed, the first position and the second position are determined based on the third input of the user to the selection control, and the first position and the second position are determined as the candidate video frame selected by the first input, so that the user can more accurately select the candidate video frame through the displayed selection control, and the operation convenience of selection is further improved.
Then, after determining the candidate video frame selected by the first input, the first electronic device may determine the candidate video frame selected by the first input as the target video frame; or determining the candidate video frame selected by the first input and the non-video key frame associated with the candidate video frame selected by the first input as the target video frame. Specifically, in the case that the candidate video frames are all video frames included in the target video, the candidate video frame selected by the first input may be determined as the target video frame. And further determining the candidate video frame selected by the first input and the non-video key frame associated with the candidate video frame selected by the first input as the target video frame in the case that the candidate video frame is determined based on the video key frame contained in the target video.
The candidate video frames are determined based on key frame images in the video to be shared, so that the target video frame also belongs to the key frame images, and each key frame image in the video is usually formed by sequentially arranging a plurality of spaced non-key images, wherein the image content of the spaced non-key images is usually similar to that of the previous key frame image, and the associated non-key frame image can be a non-key frame image between the target video frame and the next key frame image of the target video frame adjacent to the target video frame in the video to be shared. Therefore, the candidate video frame selected by the first input and the non-key frame image associated with the candidate video frame selected by the first input are determined as the target video frame, so that the images with similar contents can be encrypted at the same time, and the encryption effect is improved. Furthermore, only the target video frame can be determined as the target video frame, so that the number of the target video frames needing to be encrypted is reduced while the user requirements are met, and the encryption efficiency of the first electronic device is improved.
Step 303, the first electronic device obtains the encrypted information input by the user.
Specifically, the encryption information may be input by a user on a display interface of the first electronic device, and the first electronic device may determine that the user needs to encrypt the encrypted information when a selection operation on a preset area is detected, for example, the preset area may be an area other than a display area of a play icon of the target video. Accordingly, the first electronic device may receive encrypted information input by the user. The display interface may be an interface provided by the first electronic device specifically for inputting the encrypted information, and of course, the display interface may also be another interface, for example, the display interface may also be an interface displayed when the target video frame is selected.
For example, fig. 3 to 6 are schematic diagrams of still another user interface provided by an embodiment of the present invention, as shown in fig. 3 to 6, a user inputs encrypted information on the interface, where the encrypted information is an image capable of embodying a shape and input by the user.
And step 304, the first electronic device encrypts the N target video frames based on the encryption information.
Specifically, the first electronic device may associate the encrypted information with image data of the target video frame, and then store the associated encrypted information and image data of the target video frame in a metadata area of the video to be shared.

Specifically, this step may refer to step 105, which is not limited in this embodiment of the present invention.
And step 306, the second electronic device receives the target video sent by the first electronic device.
Specifically, this step may refer to step 201 described above, which is not limited in this embodiment of the present invention.
Step 307, the second electronic device obtains the decryption information input by the user of the second electronic device.
Specifically, the second electronic device may receive information input by the user from the display interface after receiving the first play operation, and further obtain the decryption information. For example, fig. 3-8 are schematic diagrams of still another user interface provided by the embodiment of the present invention, as shown in fig. 3-8, a user may input decryption information on a display interface.
And 308, the second electronic device plays the target video under the condition that the decryption information is matched with the encryption information, and plays the N target video frames in the playing process of the target video.
In this step, the encrypted information may be stored in a metadata area of the target video, and accordingly, the second electronic device may match the decryption information with the encrypted information in the metadata area, specifically, may compare the decryption information with the encrypted information to match the decryption information with the encrypted information, then, if the matching is successful, read the image data associated with the encrypted information from the metadata area, specifically, if the similarity between the decryption information and the encrypted information reaches a preset threshold, it may be considered that the matching between the decryption information and the encrypted information is successful, at this time, read the image data associated with the encrypted information, and finally, in the playing process of the target video, play the encrypted N target video frames based on the image data, specifically, determine the playing time point of the encrypted video frame according to the playing time information included in the image data, and when the playing time point is reached, rendering by using the image data to realize playing of the target video frame. In the embodiment of the invention, the decryption information is matched with the encryption information in the metadata area, and the N target video frames are played under the condition of successful matching, so that a user of the second electronic equipment can watch the target video frames under the condition of watching qualification, the safety of the target video frames is improved, meanwhile, the first electronic equipment can realize the watching control of part of contents in the target video based on the encryption information without cutting the target video, and the processing process of the first electronic equipment can be simplified.

Specifically, the second electronic device may obtain an identifier of a second candidate video frame based on the association relationship, then may determine which video frame in the target video is the second candidate video frame according to the image identifier, and then play the second candidate video frame according to the play parameter, which is assumed as follows: the playing time is 2, the second electronic device may play the second candidate video frame twice. Therefore, the second candidate video frame is played based on the playing parameters to play in a specific form, and the interestingness of video playing can be improved to a certain extent.
Further, when a direct playing request for playing the target video is received, or the decryption information is not matched with the encryption information, only video frames except the N target video frames in the target video are played in the playing process of the target video.
Specifically, the direct play request does not include the decryption information, that is, the second play operation may be a trigger operation for a direct play function of the second electronic device, for example, the second play operation may be a click operation for the target video, and accordingly, if the second play operation is received, it may be considered that the user does not want to watch the target video frame in the target video, and therefore, only video frames except the target video frame in the target video may be played in the playing process of the target video. Further, if the decryption information does not match the encryption information, it may be considered that the second electronic device user does not have the right to view N target video frames, and therefore, in the case where the decryption information does not match the encryption information, only video frames other than the N target video frames in the target video may be played during the playing of the target video. In this way, when a direct playing request is received, or the decryption information is not matched with the encryption information, only the unencrypted video frame is played, so that the target video can be played differently by different second electronic devices under the condition that the same target video is shared by the different second electronic devices, and the video sharing effect is further improved.
