It should be noted that the updating method of the play sequence provided in the embodiment of the present application is generally executed by the terminal devices 101, 102, and 103, and accordingly, the updating device of the play sequence is generally disposed in the terminal devices 101, 102, and 103.

In addition, the frame set of the sequence frames to be played may be obtained by the terminal devices 101, 102, 103 from a local or other storage medium electrically connected to and interacting with the terminal devices, and in this case, the exemplary system architecture 100 may not include the server 105 and the network 104.
It should be understood that the number of terminal devices, networks, and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for an implementation.
With continued reference to FIG. 2, a flow 200 of one embodiment of a method for updating a play sequence according to the present application is shown. The method for updating the playing sequence comprises the following steps:
In this embodiment, an execution main body (for example, the terminals 101, 102, and 103 shown in fig. 1) of the method for updating a play sequence may receive a play sequence frame and/or a different play set for different types of frames in the play sequence frame sent from a server (for example, the server 105 shown in fig. 1), or may obtain the play sequence frame and/or the different play set for different types of frames in the play sequence frame from a local or non-local storage device that may be directly electrically connected to and transmitted by the execution main body, where there may be a plurality of different types of frames in the play sequence frame based on different play contents and/or functions.
The execution main body can directly acquire the playing sequence frame and then analyze the playing sequence frame locally to acquire different types of frames existing in the playing sequence frame and further acquire different playing sets aiming at the different types of frames, and can also directly acquire the different playing sets aiming at the different types of frames in the playing sequence frame.
It should be understood that the currently playing sequence frame generally refers to a sequence frame currently in a playing state, i.e., a playing sequence frame being played, or a content generated based on the currently playing sequence and played in the currently playing sequence is the content in the currently playing sequence frame.
After different play sets aiming at different types of frames in the current play sequence frame are obtained, the different play sets are correspondingly added into buffer pools aiming at different types of frames, for example, the play sets are animation content play sets and are added into the corresponding animation type frame buffer pools.
The buffer pool generally refers to a data structure of a sequence frame sequence queue constructed in advance for different types of frames, where the length of the queue is generally related to the length of playing sequence frames, for example, when the number of frames of a specific type of playing sequence is 10 frames, the number of frames allowed to be stored in the corresponding buffer pool is also 10 frames, so as to just meet the storage requirement of playing sequence frames and avoid waste of resources.
After the play set is obtained, the frames existing in the play set may be sequentially decoded, and the decoded frames are sequentially stored in the buffer pool, and when playing is subsequently performed, the frames are obtained from the buffer pool and then are combined into a play sequence for playing.
It should be understood that, because different types of frames have different functions, buffer pools for different types of frames are generated for different types of frames, for example, a first type frame is stored in the first type frame buffer pool, a second type frame is stored in the second type frame buffer pool, and the first type frame and the second type frame are stored in the two buffer pools, so as to process the first type frame and the second type frame respectively, thereby avoiding the problems of excessive memory occupation and low processing efficiency caused by mixed-coding of different types of frames by using a single buffer pool in the prior art, and improving the updating efficiency of the play sequence.
In step 202, in response to detecting a play update instruction, an update set for different types of frames indicated by the play update instruction is obtained.
In this embodiment, when a play update instruction is detected, that is, when the execution main body receives an instruction to update the play content, an indicated update file exists in the update instruction, the indicated update file is obtained, and then types of frames in the update file are analyzed to obtain update sets of frames of different types, so that the play content is updated by using the update sets.
The playing updating instruction may be issued to the execution main body based on the requirement of the user, or may be sent to the execution main body according to a preset rule, for example, a timing unit, according to a time rule, so as to update the playing content, that is, the playing sequence.
Correspondingly, in order to improve the efficiency of the whole process, a proper screening rule can be adaptively set for the execution main body, the scanning work of the playing updating command is carried out under a preset condition, for example, the scanning is carried out at a preset time node, whether the playing updating command is received in a preset time period or a preset condition is detected, the resource waste caused by always scanning the playing updating command is avoided, and similarly, under some scenes with higher precision requirements, the playing updating command can also be always scanned, so that the quick response to the playing updating command is realized, and the setting can be carried out in combination with specific requirements.
In addition, the obtaining manner of the update file is similar to the obtaining manner of the play sequence in step 201, which is not described again.
In this embodiment, after an update set for different types of frames is obtained, a corresponding buffer pool is found, and the content therein is updated, where the update mode may be replaced one by one according to different requirements, or the content in the buffer pool may be directly emptied, and then the updated content is programmed into the buffer pool, for example, after the frames in the buffer pool of a specific frame have been programmed into a play sequence, the content in the buffer pool corresponding to the characteristic frame may be emptied for improving the update efficiency, or when the frames in the buffer pool of another type of frame have not been programmed into the play sequence, when the frames are programmed into the play sequence in sequence, another type of frame may be continuously added thereto to update the buffer pool of the another type of frame.
And step 204, updating the playing sequence obtained according to the current playing sequence frame by sequentially using the buffer pools aiming at the different types of frames.
In this embodiment, because different types of frames have different functions, a suitable manner is selected according to the different functions to extract stored frames from the buffer pool to encode the frames into a play sequence, so as to implement updating of the play sequence.
For example, when the type of the frame is an insertion frame, and the play sequence is updated, the insertion frame is correspondingly inserted to realize the insertion of the content.
The method for updating the play sequence provided by the embodiment of the application obtains different play sets aiming at different types of frames in a current play sequence frame, and respectively adds the play sets to buffer pools aiming at the different types of frames, responds to the detection of a play update instruction, obtains an indicated update set aiming at the different types of frames, adopts the update set aiming at the different types of frames to update the buffer pools aiming at the different types of frames, sequentially uses the buffer pools aiming at the different types of frames, updates the play sequence obtained according to the current play sequence frame, improves play fluency by setting the buffer pools, can link up the play processes of the different sequence frames through the programming of the different types of frames, and avoids the phenomena of black screen and pause caused by the switching of the different sequence frames in the play process.
With continued reference to fig. 3, another embodiment flow 300 of a method for updating a play sequence according to the present application is shown. The method for updating the play sequence comprises the following steps:
In this embodiment, the first type frame generally refers to a set of frames related to core playing content, the second type frame generally refers to a set of frames related to inserted content and playing an auxiliary role, and when the first type frame and the second type frame are set, or a first playing set for the first type frame and a second playing set for the second type frame are connected and a playing sequence is generated by sequentially using the contents in the first playing set and the second playing set for playing, continuous playing can be performed based on the contents in the first playing set and the second playing set, switching between different first playing sets is completed, and the problem of blocking during video switching when different first playing sets are directly and continuously encoded into the playing sequence is solved.
Illustratively, when the sequence frames are expression animation sequence frames for the intelligent robot, the first type of frames refer to frames related to expressions presented by the intelligent robot (such as frames displaying smiling, laughing and crying expressions), the second type of frames refer to frames used when different expression sequence frames are switched (such as frames displaying a face-covering action), and when one expression sequence frame is switched to another expression sequence frame (such as smiling-covering face-laughing), the frames which are connected and displayed in an auxiliary mode are played when the two different expression sequence frames are switched.
It should be understood that there is usually a correspondence between a first play set for a first type of frame and a second play set for a second type of frame, i.e. different first play sets have different second play sets corresponding thereto.
In this embodiment, when it is determined that the number of the remaining unplayed first type frames in the play sequence obtained according to the current play sequence frame satisfies a predetermined threshold condition, usually, the threshold condition is to detect whether the number of the remaining unplayed first type frames is 2 or 1, and to detect whether a play update instruction is received.
The detection interval is set to be the time from the time when the first frame of the play sequence starts playing to the time when the number of the first type frames which are not played remains in the play sequence, so as to judge whether an update instruction is received in the time interval through one-time detection, and avoid resource waste caused by repeated detection.
In this embodiment, after the step 302 is completed, when the play update instruction is not detected, that is, it is determined that the play sequence obtained according to the currently played sequence frame does not need to be updated, after the play sequence is completed, the play sequence is reused for playing, that is, the play sequence is skipped to the first frame of the first type frame in the currently played sequence frame and played according to the first type frame, so as to implement the circular play when the update instruction is not received, and avoid the interruption of the play.
In response to detecting the play update instruction, an updated first type frame set and an updated second type frame set for the first type frame and/or for the second type needle indicated by the play update instruction are obtained 304.
In this embodiment, after receiving a play update instruction, it is determined that the play sequence needs to be updated, and the first type frame set and the second type frame set for the first type frame and/or for the second type needle indicated in the play update instruction are obtained.
It should be understood that the updating of the first type frame set and the updating of the second type frame set may be obtained simultaneously or separately according to different requirements, so that the updating of the playlist is realized by using the contents in the updating of the first type frame set and the updating of the second type frame set separately or jointly.
In general, because the selected links in different frame sequences are set based on the content of the frame sequences, the first type frames and the second type frames of the different frame sequences are not the same, and it is more common to acquire the updated second type frames and update the second type frames at the same time.
In this embodiment, based on the obtaining situation of updating the first-type frame set and/or updating the type frame in the step 304, the first-type frame buffer pool and/or the second-type frame buffer pool are updated separately or simultaneously, and the buffer pool may be updated in a manner similar to that described in the step 202 in the embodiment shown in fig. 2, which is not described again.
In some optional implementations of this embodiment, the updating the first-type frame buffer pool with the updated first-type frame set includes: emptying the first type frame buffer pool, storing the updated first type frame set into the first type frame buffer pool, and updating the first type frame buffer pool.
In one embodiment, when the first type frame buffer pool is updated by using the update set for the first type frame, because the first type frame is a main content frame in this embodiment, that is, the content of the first type frame is mostly/completely replaced with the difference of the play sequence frame, during the process of updating the first type frame buffer pool, the content stored in the first type frame buffer pool is first emptied, and then the update set for the first type frame is directly stored in the first type frame buffer pool at one time, so as to improve the update efficiency.
In some optional implementations of this embodiment, the updating the second-type frame buffer pool by using the updated second-type frame set includes: after extracting the frame in the second type frame set from the second type frame buffer pool, correspondingly storing the frame in the updated second type frame set, and updating the second type frame buffer pool.
In an embodiment, when the second-type frame buffer pool is updated by using the update set for the second-type frame, since in this embodiment, the content of the second-type frame mainly plays an auxiliary role for linking content, when sequence frames of different contents are switched, the original content in the second-type frame buffer pool needs to be used, so when the second-type frame is selected to be extracted from the second-type frame buffer pool (usually, the extraction process is a continuous extraction process), the second-type frame is sequentially stored and updated, the content in the second-type frame buffer pool is updated based on the original storage space, and the memory space is saved while the use requirement is met.
In this embodiment, because the content of the second type frame mainly plays an auxiliary role for linking the content, when different sequence frames are switched, the content of the second type frame needs to be coded for linking, and therefore when a play update instruction is detected, that is, when the play content needs to be updated, the content of the second type frame is coded into the play sequence, so as to play the second type frame for linking after the play of the first type frame in the currently played sequence frame is completed.
In some optional implementations of this embodiment, the second type frames in the second type frame buffer pool are reversely encoded into the play sequence; and the frames in the updated second-type frame set in the second-type frame buffer pool are coded into the playing sequence in a forward sequence.
In one embodiment, in order to better implement the update of the second type frame buffer pool, the second type frames in the second type frame buffer pool are inversely coded into the playing sequence, for example, the number sequence of the second type frames existing in the second type frame buffer pool is 1, 2, 3 … … N, (where N is a positive integer), then the second type frames are coded into the playing sequence according to the coding sequence of the number sequence N, N-1, N-2 … … 1, and then the contents in the updated second type frame set are sequentially coded into the second type frame buffer pool, so as to implement the fast and continuous update of the buffer pool of the queued data structure.
It should be understood that, in this implementation, the second type frames referred to in this embodiment are generally repeated or support reverse-order extraction of played frames, and when the second type frames in the play set for the second type frames support reverse play and have different contents, different viewing experiences can also be provided for the user, so as to avoid the viewing fatigue of the user caused by repeated display.
In some optional manners of this embodiment, the method further includes: continuously deleting the frames of the second type frame buffer pool into which the playing sequence is coded; and stopping deleting the frames which are coded into the playing sequence in the second type frame pool in response to the fact that the frames currently coded into the playing sequence are the updated second type frames which are predetermined in the updated second type frame set.
