DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present disclosure clearer, the technical solution in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0031] Before introducing the embodiments of the present disclosure, the professional terms and application background involved in the embodiments of the present disclosure are first explained:

[0032] Editing materials on the timeline: refers to the process of editing, modifying and processing materials in video editing software. Non-linear editing refers to the editing method that allows you to select and combine material clips at will according to personal needs, without having to edit in a linear order;

[0033] Data model layer: It is the data structure used in editing software to manage and store materials and editing information;

[0034] Sequence: refers to a separate editing sequence created in the editing software, which contains multiple video tracks and audio tracks and is used to organize and manage the order of materials;

[0035] Clip: A data model layer object that represents a clip of a material, which contains the material's content, duration, attributes, and other information. It is the basic unit on the timeline and can be placed on different tracks;

[0036] Track: A data model layer object that represents a track, used to manage and organize the order of clips. On the timeline, you can create multiple tracks and place different clips on different tracks to achieve the desired editing effect;

[0037] The relationship between the model layer, the engine layer (i.e., the editing engine), and the business layer is as follows: the model layer is responsible for managing the data model in the editing software, the engine layer is responsible for implementing the core functions and algorithms of the editing software, and the business layer provides the interface and operation logic of the editing software to the outside world, which involves data updates, etc.

[0038] The business layer calls Modify Clip: This means that the business layer in the editing software calls the Modify Clip function to modify the properties of the material clip or perform other editing operations;

[0039] Deep copy and Lock mechanism: These are two different ways to handle modification conflicts. Deep copy means making a copy of the data before modifying it, and then modifying it, thus avoiding conflicts between multiple operations. Using the Lock mechanism means that when modifying the data, a lock operation is performed first, and other operations need to wait for the lock to be released before continuing, to ensure that only one operation can modify the data at the same time. Which method to use should be determined according to the specific situation to avoid data conflicts and ensure data consistency;

[0040] Timeline: It is the main interface used in editing software to organize and display clips and editing operations. It can contain multiple tracks, and each track can hold multiple clips of the material.

[0041] Clip engine ref count: refers to the number of times the clip object is referenced in the engine layer, which is used to track the use of the clip. When the clip reference count is zero, it means that the clip is not used anywhere and can be released or recycled;

[0042] In non-linear editing, editing of materials on the timeline often requires the use of data models to convert the data to be edited into the timeline. The editing engine calls the data required for editing based on the timeline. In order to meet their needs, users often introduce new data during editing to meet their own editing needs.

[0043] In the prior art, when updating data, the editing engine is often controlled to stop running. After the data is added, the data model rebuilds a new timeline based on user needs and the updated data. The editing engine calls the required data for the reconstructed timeline, continues to complete the editing operation, and obtains the editing result.

[0044] Right now, Figure 1 A flow chart of a data updating method provided by the prior art, such as Figure 1 As shown, the process of the prior art includes:

[0045] Step 11, start;

[0046] Step 12: Stop the engine layer.

[0047] Step 13: Update the data of Sequence (ie, Modify Sequence);

[0048] Step 14: Completely create a timeline (i.e., timeline);

[0049] Step 15: Start the engine layer operation;

[0050] Step 16, end.

[0051] In the prior art, the data model layer modifies / accesses the Track+clip object of the Sequence layer, and the engine layer accesses the Track+clip object of the Sequence layer.

[0052] However, there are the following problems in the prior art:

[0053] 1. Since the editing engine needs to stop editing operations, the system may freeze;

[0054] 2. After the engine stops running, it takes a long time to restart, resulting in low editing efficiency;

[0055] 3. The user experience is poor.

[0056] On the basis of the above-mentioned technical problems, the inventor's technical conception is as follows: in the existing operation of stopping the engine when updating data, the purpose is to prevent the engine layer from accessing and consuming the Sequence during operation. However, in fact, the data really needed by the engine layer are all obtained from the clip, that is, there is a conflict between the read operation on the clip and the write operation on the clip when updating the data. If, when updating the data, the clip involved in the updated data can be analyzed, and the count number of times the clip is referenced by the engine layer is determined, then the data can be updated by using a deep copy or a Lock mechanism according to the count number, thereby ensuring that the consumption of the engine layer is not affected. Then, on the basis of realizing data updating, the problems existing in the prior art can be solved. That is, the present disclosure proposes a data updating method and device.

[0057] The technical solution of the present disclosure is described in detail below through specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0058] It is worth noting that the application fields of the data updating method and device disclosed in the present invention are not limited and may include: the field of computer technology. Among them, the execution subject of the present invention is an electronic device, which may be a mobile phone, a tablet, a computer, a server and other devices.

[0059] Before introducing the method embodiment of the present invention, the implementation architecture process involved in the method of the present invention is described. Figure 2 ( Figure 2 As shown in the data updating method architecture diagram provided by the present disclosure, the process of the present disclosure includes:

[0060] Step 21, start;

[0061] Step 22: Update the data of Sequence in a thread-safe manner (ie, ModifySequence with thread safety);

[0062] Among them, thread safety can be ensured by copying or locking;

[0063] Step 23: incrementally update the timeline (i.e., only update the clips involved in updating the data in the timeline);

[0064] Step 24, end.

[0065] In the present disclosure, the data model layer modifies / accesses the Track+Clip object of the Sequence layer, and the engine layer accesses the clip object of the Sequence layer, that is, thread safety is narrowed down to the clip.

[0066] It should be understood that: Figure 2 Only the general architecture of the present disclosure is introduced, and the contents not described in detail are explained by the embodiments involved in the following data updating method.

[0067] Figure 3 A schematic diagram of the data updating method provided in the embodiment of the present disclosure Figure 1 ,like Figure 3 As shown, the method may include the following steps:

[0068] Step 31: In response to an update operation performed by a user on data in video editing, a target segment corresponding to the update operation is determined in at least one segment;

[0069] The clip includes the data to be edited which is required to be referenced by the editing engine corresponding to the video editing.

[0070] In this step, during the video editing process, when the user needs to update the edited data, the electronic device responds to the user's update operation and determines the target clip involved in the update operation from multiple chips.

[0071] The data to be edited may be materials such as videos, pictures, and audios to be edited; and the updated data may include: modifying data, adding data, deleting data, and the like.

[0072] In this implementation, the objects in the data model layer that the editing engine can access are limited, and thread safety is ensured for a small number of objects. That is, the editing engine can currently access the Track+Clip objects of the Sequence layer (Filter currently supports hot updates through a lock mechanism and is not considered), but the data that the editing engine actually needs during operation is actually obtained from the clip. Some information that needs to be obtained from the Track can also be synchronized from the Track to the clip. By limiting the Sequence objects that the editing engine can access, the editing engine can only access the clip. Therefore, it only needs to determine the clip involved in the update operation (i.e., the target clip).

[0073] In a possible implementation, the user needs to add background music during the editing process, and at this time, the clip involved in the background music is determined as the target clip.

[0074] Optionally, step 31 may be implemented as follows:

[0075] Step 1: In response to the update operation, listen to the corresponding event of the update operation to obtain the fragments involved in the corresponding event;

[0076] Step 2: In at least one segment, a segment involved in the corresponding event is determined as a target segment.

[0077] After receiving the relevant instruction of the user for the data update operation, the electronic device monitors the corresponding event in response to the instruction, determines the involved clip from the corresponding event, and uses the clip as the target clip involved in the update operation.

[0078] That is, the clip involved in the data corresponding to the update operation is determined.

[0079] Step 32: According to the count of the number of times the target segment is referenced by the editing engine, determine whether to update the data in the target segment by locking the target segment or by copying and replacing the target segment.

[0080] In this scheme, the copy-after-replace or lock method involves a deep copy or lock mechanism, respectively;

[0081] In this step, the clip engine refcount is used to track the usage of the clip. When the clip count is zero, it means that the editing engine is not using the clip anywhere; when the clip count is not zero, it means that the editing engine will consume the clip.

[0082] Furthermore, based on the count of the number of times the target clip is referenced by the editing engine, it is determined whether to update the data of the target clip under a deep copy or a lock mechanism.

[0083] Among them, deep copy is to copy data before modifying it, so that each operation has its own copy to modify, avoiding modification conflicts. The lock mechanism is to lock the shared resources and block the access of other operations during the modification, ensuring that only one operation can modify the resources at the same time, avoiding concurrency conflicts. That is, for materials that are frequently modified (i.e. data), deep copy will be more efficient, and locking will trigger frequent lock mutual exclusion. For materials that are not frequently modified, locking is more efficient.

[0084] Both of the above methods can ensure data consistency and avoid conflicts. In editing, deep copy and lock mechanisms can be used to handle modification conflicts of clip and Track objects to ensure the correctness and consistency of editing operations.

[0085] Step 33: Update the timeline corresponding to the video editing.

[0086] The timeline records information about clips that the editing engine needs to reference at different time points.

[0087] In this step, the consumption of the editing engine relies on reading the information on the timeline to implement the editing event. After the above data is updated, the timeline is updated.

[0088] Optionally, step 33 may be implemented as follows:

[0089] Step 1: Mark the target fragment as dirty;

[0090] Step 2: After the data in the target segment is updated, the dirty target segment is re-rendered or a corresponding operation is performed on the timeline.

[0091] Optionally, the data corresponding to the update operation may be marked dirty to determine the update point of the data, and then the clip corresponding to the update point may be re-rendered or a corresponding operation may be performed.

[0092] The dirty processing may be achieved by setting a dirty flag on a target. For example, the target may be a target clip or data corresponding to an update operation.

[0093] In a possible implementation, after clip A is updated, clip A is re-rendered on the timeline, that is, the re-rendered clip A on the updated timeline moves compared to the previous clip A.

[0094] In this implementation, the timeline display is updated or related operations are performed according to the modified content of the target clip. The specific update method can be determined according to business needs, such as updating the properties of the target clip, adjusting the position of the target clip on the timeline, etc. It is important to keep the data of the timeline and the target clip synchronized to ensure that the editing results are correctly presented on the timeline.

[0095] Optionally, each position on the timeline represents a specific time point in the video. Different clips can be added, deleted, adjusted, and combined on the timeline. The editing engine is responsible for processing and rendering the operations on the timeline to achieve the final video editing effect.

[0096] The data updating method provided by the disclosed embodiment determines the target segment corresponding to the update operation in at least one segment in response to the user's update operation on the data in the video editing, and the segment is used to store the to-be-edited data required to be referenced by the editing engine corresponding to the video editing, and determines to perform the update operation on the data in the target segment by locking the target segment or by copying and replacing it according to the count of the number of times the target segment is referenced by the editing engine, and then updates the timeline corresponding to the video editing, which records the information of the segments that the editing engine needs to reference at different time points. In this technical solution, the number of times the segment involved in the data update is referenced by the editing engine is counted to determine whether the update of the segment needs to be updated by copying and replacing it, or by directly locking it, so as to avoid the read-write conflict caused by the editing engine calling the segment, thereby ensuring the smooth operation of the editing engine and improving the editing efficiency.

[0097] Based on the above embodiments, Figure 4 A schematic diagram of the data updating method provided in the embodiment of the present disclosure Figure 2 ,like Figure 4 As shown, the above step 32 may include the following steps:

[0098] Step 41: If the count of the number of times the target segment is referenced by the editing engine is greater than 0, copy the target segment to generate a copy segment corresponding to the target segment;

[0099] In this step, when it is determined that the target clip is referenced by the editing engine by a count greater than 0, it means that the editing engine will consume the target clip, that is, the target clip is frequently modified. When updating the data of the target clip, a deep copy will be more efficient.

[0100] At this time, a copy operation is performed on the target clip to obtain a copy clip corresponding to the target clip.

[0101] Optionally, the target clip still provides services for the editing engine and does not affect the operation of the editing engine.

[0102] Step 42: Update the data in the replica fragment and replace the updated replica fragment with the target fragment.

[0103] In this step, the data in the copy clip is updated according to the matters corresponding to the update operation, and after the update is completed, the updated copy clip is replaced with the target clip.

[0104] That is, the editing engine consumes the updated copy clip.

[0105] The data updating method provided by the embodiment of the present disclosure copies the target clip if the count of the number of times the target clip is referenced by the editing engine is greater than 0, generates a copy clip corresponding to the target clip, updates the data in the copy clip, and replaces the updated copy clip with the target clip. In this technical solution, when the editing engine consumes the target clip, the target clip is copied and the data is updated to avoid interfering with the normal operation of the editing engine.

[0106] Based on the above embodiments, Figure 5 A schematic diagram of the data updating method provided in the embodiment of the present disclosure Figure 3 ,like Figure 5 As shown, the above step 32 may include the following steps:

[0107] Among them, after step 51, steps 52 and 53 may be executed; or steps 54, 55 and 56 may be executed, depending on the actual situation.

[0108] Step 51: If the count of the number of times the target segment is referenced by the editing engine is equal to 0, the target segment is locked, and the count of the number of times the target segment is referenced by the editing engine is determined again;

[0109] In this step, when it is determined that the target clip is referenced by the editing engine and the count is equal to 0, it means that the editing engine will not consume the target clip, that is, there is no change to the target clip. When updating the data of the target clip, a lock mechanism can be used.

[0110] Before modifying the data in the target clip, a lock operation is performed first, and other operations need to wait for unlocking (i.e., the release of the lock) before continuing, to ensure that only one operation can modify the data at the same time.

[0111] Furthermore, it is necessary to determine again the count of the number of times the target clip is referenced by the editing engine.

[0112] In this implementation, a double check is used to more accurately determine whether the target clip is being consumed, so as to avoid affecting the normal operation of the editing engine. Specifically:

[0113] First judgment: In order to improve the code execution efficiency, since the singleton mode only needs to create an instance once, after creating an instance, it is unnecessary to enter the synchronization code block when calling the getInstance method again, and there is no need to compete for the lock. Just return the previously created instance directly.

[0114] Second judgment: This check is to prevent the secondary creation of instances. If there is a situation, for example, when singleton has not been created, thread t1 calls the getInstance method. Since the first judgment singleton == null, thread t1 is ready to continue execution, but because the resources are preempted by thread t2, t2 calls the getInstance method at this time.

[0115] Step 52: If it is determined again that the count of the number of times the target segment is referenced by the editing engine is equal to 0, the data in the target segment is updated.

[0116] In this step, after two determinations, if the count of the number of times the target clip is referenced by the editing engine is still equal to 0, it means that the editing engine will not consume the target clip and perform an update operation on the target clip.

[0117] Step 53: unlock the updated target fragment;

[0118] In this step, after the target clip is updated, the updated target clip needs to be unlocked to prevent the editing engine and the like from performing corresponding read and write operations on the updated target clip in subsequent editing operations.

[0119] Step 54: If it is determined again that the count of the number of times the target segment is referenced by the editing engine is greater than 0, the target segment is unlocked;

[0120] After step 51, if it is determined again that the target clip is referenced by the editing engine and the count is greater than 0, the target clip needs to be updated according to the above steps 41-43 (ie, steps 55-56), which will not be repeated here, and please refer to the above embodiment.

[0121] Step 55: copy the target segment to generate a copy segment corresponding to the target segment;

[0122] Step 56: Update the data in the replica fragment and replace the updated replica fragment with the target fragment.

[0123] The data updating method provided by the embodiment of the present disclosure is as follows: if the target clip is referenced by the editing engine, the target clip is locked, and the target clip is referenced by the editing engine again. If the target clip is referenced by the editing engine again, the target clip is updated. If the target clip is referenced by the editing engine again, the target clip is unlocked. In addition, if the target clip is referenced by the editing engine again, the target clip is unlocked. The target clip is copied to generate a copy clip corresponding to the target clip. The data in the copy clip is updated and the updated copy clip is replaced with the target clip. In this technical solution, when the editing engine does not consume the target clip, the target clip is referenced by the editing engine again to determine whether the deep copy or lock mechanism is used for the update operation. The double check method can more accurately determine whether the target clip is being consumed. When it is determined that the target clip is not consumed, the lock mechanism is used to prevent the access of other operations from being blocked during the modification period, so as to ensure that only one operation can modify the resource at the same time, avoid concurrent conflicts, and improve the modification efficiency and system fluency.

[0124] Based on the above embodiments, Figure 6 A schematic diagram of the data updating method provided in the embodiment of the present disclosure Figure 4 ,like Figure 6 As shown, the above step 32 is described again, and the step may include:

[0125] Step 1. Start;

[0126] Step 2: Start updating the clip (i.e. the target clip)

[0127] Step 3: Determine whether the count is greater than 0; if so, go to step 4; if not, go to step 7;

[0128] Step 4: Copy the clip to get a copy of the clip;

[0129] Step 5: Modify the copy clip;

[0130] Step 6: End;

[0131] Step 7. Lock the clip;

[0132] Step 8: Determine whether the count is greater than 0; if so, go to step 9; if not, go to step 10;

[0133] Step 9. Unlock the clip and execute step 4;

[0134] Step 10: Modify the clip;

[0135] Step 11. Unlock the clip and execute step 6.
