Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In an online video clip scenario, live preview of multiple clips is one of the main functions.
The multiple video clips are typically decoded in sequence by software decoding and rendered in real-time in the player. The software decoding may be implemented by a software decoding program, which may be a separately configured program that is called for software decoding when decoding is performed. In addition, the software decoding program may be combined with the running program of the online video editing tool.
The decoded image of each video clip is added to the final stitched video frame by frame to preview the final effect in real time. This approach allows for immediate viewing of the spliced video effects, but may take up more computing resources. Specifically, the software decoding program can be configured at the client and also can be configured at the server, for long video played by splicing, the software decoding consumes more resources (such as CPU (Central ProcessingUnit, central processing unit) computing resources and the like) and requires longer loading time, which is time-consuming, and when the client is in a client, performance bottlenecks exist, and the situation that video cannot be played by splicing due to insufficient resources exists, so that user experience is reduced.
Therefore, the inventor finds that if the corresponding video clips can be directly played, and decoding each video clip into a frame image for rendering by a software decoding mode is not needed, the problems of calculation resource waste and time consumption caused by decoding into the frame image can be reduced.
Specifically, the invention provides a video playing method, a device and equipment, when playing a target video clip, determining the target video clip to be played, and judging whether a target video clip object corresponding to the target video clip is stored in a preset cache queue ， And if so, calling and playing the video content corresponding to the video playing time point in the target video clip object from the preset cache queue. In the invention, the target video clip object is directly played, and each video clip is not required to be decoded into a frame image for rendering in a software decoding mode, so that the resources occupied by video playing can be reduced, the waiting time of video playing is shortened, and the user experience is improved.
In addition, in the invention, the online video editing tool is generally a Web (world Wide Web) tool and runs on a browser, and the browser has hardware decoding capability, and can call the hardware at the bottom layer of the terminal to carry out decoding operation when the video clip object is played. Compared with the software decoding, the hardware decoding mainly relies on CPU resources, the hardware decoder is integrated to the hardware bottom layer, and the hardware decoder mainly relies on GPU (Graphics Processing Unit, graphics processor), so that the CPU can be greatly liberated, the occupation of resources such as CPU computing resources can be reduced, namely, compared with the software decoding, the hardware decoding uses fewer resources, and the problems that video cannot be spliced and played due to insufficient resources and user experience is reduced can be avoided. In addition, hardware decoding is more efficient than software decoding, and time consumption can be reduced.
However, when the hardware decoding is used, only the hardware decoding of a single video is supported, and the scene aimed by the method is the situation that a plurality of videos are spliced and played, namely, the plurality of videos need to be decoded by hardware, and at the moment, each video can be sequentially called to be decoded and played, so that the problem of multi-video hardware decoding is solved.
In addition, in order to reduce time consumption, the video to be decoded can be instantiated in advance to obtain a video clip object and stored in a preset cache queue, and when the video clip object needs to be played, the video clip object is directly called to be decoded and played, so that the time consumption required for creating the video clip object is reduced, and the playing waiting time is reduced.
In an embodiment of the present invention, a video playing method is provided, which is applied to a terminal with a browser function, such as a mobile phone, a computer, etc. The terminal is configured with an online video editing tool, such as a cloud editing tool, through which video editing of movies, television shows, sports, etc. is performed. The tool carries out online video editing through a Web page of a browser, and scenes such as secondary creation video editing all have use scenes of the online editing. In this scenario, if a plurality of video clips need to be played, the video playing method in this embodiment may be used.
It should be noted that, the execution body of the video playing method may be an operation program of an online video editing tool in the terminal, and specifically may be an independent scheduler program and timer program in the operation program, or a total program formed by combining the scheduler program and the timer program. Wherein the scheduler program is used for scheduling the specific video clip to play according to the whole main time axis.
Referring to fig. 1, the video playing method may include:
s11, under the condition that a video playing instruction is received, acquiring a video playing time point in the video playing instruction.
The video playing time point is a time point on a main time axis corresponding to a video queue, the video queue comprises a plurality of video clips to be spliced and played, and the main time axis consists of time axes corresponding to the video clips.
In detail, if the user uses the online video editing tool, the user may drag and adjust the sequence of the plurality of video clips and adjust the length of a certain video clip, which generally needs to clip or sequentially arrange the plurality of clipped video clips under the Web interface.
The plurality of video clips arranged in the order set by the user may form a video queue, that is, the video queue is a queue composed of all video clips arranged on the track during the clip process.
Each of these video clips in the video queue has a corresponding video duration, such as 1 minute, 30 seconds, etc. The video queues formed by the video clips arranged in sequence correspond to a main time axis, and the main time axis is a time axis corresponding to the total duration of the video clips spliced in sequence in the clipping process. For example, if there are 3 video clips of 1 minute, each video clip corresponds to a time axis of 1 minute, and the length of the main time axis is the sum of the durations of the three video clips of 1 minute, that is, 3 minutes.
It should be noted that, since the user may adjust the video duration in real time, delete or add a video clip during video editing, the length of the main time axis in this embodiment is continuously changed. Then the current video queue needs to be maintained in real time according to user operations (e.g., deletion, addition, adjustment of video clip order, etc.) on the track during the editing process, and the length of the main timeline is calculated accordingly.
When the user wants to preview the video clip, the user clicks a position point on the main time axis according to the video clip that the user wants to play, for example, the 30 th second is a video playing time point in the embodiment, that is, the video playing time point is a time point set by the user when the video starts playing, where the time point is a time point on the main time axis that needs to be played currently. After receiving the playing operation of the user, the user considers that a video playing instruction in a Web interface where the specified browser page, namely the online video editing tool is located is received, and a video playing time point in the video playing instruction is obtained.
S12, determining a target video clip corresponding to the video playing time point from the plurality of video clips.
Specifically, after determining the video playing time point, it is further required to determine which video clip corresponds to the video playing time point, that is, which video clip needs to be played.
In practical applications, step S12 may specifically include:
1) And acquiring the arrangement sequence and the video duration of each video clip.
Wherein the arrangement order is obtained based on user settings, and the specific setting process refers to the corresponding parts. The arrangement sequence of each video clip is the arrangement sequence of all video clips on the track, such as video clips 1, 2, 3, 4 and 5 are arranged according to the sequence of 1, 3, 2, 4 and 5.
The video duration refers to the time length of the video segments, for example, 1 minute, 30 seconds, etc., and the video duration of each video segment may be the same or different, which is not limited in this embodiment.
2) And calculating the position of the video playing time point in the video duration of each video segment based on the video duration of each video segment, and searching the target video segment corresponding to the position according to the sequence of each video segment.
Specifically, knowing the video duration of each video clip and the video play time point to be played, first determining the position of the video play time point in the video duration of the video clip.
For example, assuming that the video playing time point is 2 minutes and 10 seconds, and there are 1, 2, 3, 4 and 5 video clips, and the video durations are all 1 minute, the video duration corresponding to 2 minutes and 10 seconds is 10 seconds of the third video.
Then, according to the sequence of each video segment, searching which video is the third video, and taking the third video as a target video segment.
The steps S11 and S12 may be calculated by a timer program.
S13, judging whether a target video clip object corresponding to the target video clip is stored in a preset cache queue; if yes, go to step S14.
Wherein the target video clip object is a video player instance created for the target video clip by using an API provided by a video play library.
Specifically, in order to use the hardware decoding mode, a function of creating a Video object by using a browser is required, in this embodiment, an object of a Video clip needs to be created through an instantiation operation to obtain a Video clip object, and then the Video object can be decoded in hardware. Instantiation in this step refers specifically to one video player instance created for a video clip by using the API (Application Programming Interface, application program interface) provided by the video player library.
In order to save the time of creating the video object, in this embodiment, the video clip object may be created in advance through an instantiation operation and stored in a preset buffer queue. Video fragment objects of a preset cache queue are arranged according to the sequence of the creation time.
In order to avoid the problem of more occupied memory resources caused by more video clip objects stored in the preset buffer queue, in this embodiment, the number of video clip objects in the preset buffer queue is limited.
In practical application, a preset number is set, specifically, a technician configures according to practical situations, then determines the total number of video clip objects stored in a preset cache queue, and deletes the video clip object stored in the preset cache queue first when the total number is greater than the preset number.
The video clip object stored in the preset cache queue first is deleted, and because the video clip object has a larger probability of being played compared with the video clip object which enters later, and has a smaller probability of being played later, the meaning stored in the preset cache queue is not great, so that the video clip object needs to be deleted. After deletion, if the play requirement is still met, the video clip object can be restored through the restoration function.
On the basis of the preset cache queue, whether a target video clip object corresponding to a target video clip to be played is stored in the preset cache queue is further judged. If yes, the method is directly called.
When judging whether the target video segment object is stored in the preset cache queue, determining based on the identification information of the target video segment, where the identification information is a parameter for identifying the target video segment object, if the identification information of the target video segment is 1, the identification information of the corresponding target video segment object may also be the same as the identification information of the target video segment, if the identification information is 1. Regardless of how the identification information of the target video clip object is configured, a correspondence of the identification information of the target video clip and the identification information of the target video clip object should be established.
S14, calling and playing the video content corresponding to the video playing time point in the target video clip object from the preset cache queue.
Specifically, when the target video clip object is called, the identification information of the target video clip object is also based.
In detail, referring to fig. 2, step S14 may include:
S21, determining the target video segment object corresponding to the identification information from the preset cache queue based on the identification information of the target video segment object.
The identification information is a parameter for identifying the target video clip object, and the configuration process of the specific identification information is referred to the corresponding description above.
Taking the identification information of the target video segment object as 1 as an example, finding out the target video segment object with the identification of 1 from a preset cache queue.
In order to improve the searching efficiency, the video clip objects in the preset cache queue may be arranged sequentially according to the identification information, for example, the video clip objects 1, 3, 4, 5 are arranged in order from small to large. When searching the video clip object based on the identification information, searching is performed according to the sequence, and searching in a full traversal mode is not needed.
S22, determining the video fragment corresponding to the video playing time point from a plurality of video fragments forming the target video fragment object.
Specifically, each video clip object is composed of a plurality of video clips, and the video clips adopt a format of TS (Transport Stream), which is based on the M318 protocol.
In the case of splitting video clips, a video at a specified time may be taken as one video clip, for example, 3 seconds of video may be taken as one video clip.
When the video playing time point is known, the video slicing can be determined through data calculation, for example, the 4 th video slicing is 10 seconds.
S23, playing the video content corresponding to the video playing time point in the determined video fragments.
And when the video content corresponding to the video playing time point is played, calling a hardware decoding function of the browser to perform decoding operation.
Specifically, when playing the video clips, it is required to determine which content of the video clip is to be played, and specifically, the content is also obtained by calculation according to data, for example, 10 seconds is the 2 nd second content in the 4 th video clip, and then playing starts from the 2 nd second content in the 4 th video clip.
When playing, firstly, the hardware decoding function of the browser is called to perform decoding operation, namely, the hardware of the bottom layer of the terminal is adopted to perform decoding operation, after decoding, video rendering operation is performed on the video obtained through decoding, and when playing, video playing is performed at the video preview position of the Web page, such as in a player.
In the playing process, the user can adjust the playing time point of the video at any time, such as jumping to a certain video clip for playing. In addition, the order of the two video clips can be adjusted, or the playing can be paused.
If the user jumps to a certain video clip for playing, the steps S11-S14 are re-executed. If the user adjusts the order of the two video clips, the order of the two video clips in the video queue needs to be adjusted. If the user pauses the playing, the playing of the video is paused.
The steps S13 to S14 are performed by the scheduler program. In addition, the steps S11 to S14 may be performed by a total program obtained by combining the scheduler program and the timer program.
In this embodiment, when playing a target video clip, determining a target video clip to be played, and determining whether a target video clip object corresponding to the target video clip is stored in a preset buffer queue ， And if so, calling and playing the video content corresponding to the video playing time point in the target video clip object from the preset cache queue. In the invention, the target video clip object is directly played, and each video clip is not required to be decoded into a frame image for rendering in a software decoding mode, so that the resources occupied by video playing can be reduced, the waiting time of video playing is shortened, and the user experience is improved.
In addition, the embodiment decodes and splices and plays a plurality of videos through the original hard decoding capability of the browser, replaces a mode of synthesizing the plurality of videos into one video for playing through software decoding, reduces the time consumption of decoding, and avoids performance problems caused by software decoding.
In addition, the time loss caused by creating the video object in the splicing playing process is reduced by caching the video segment object in the preset cache queue.
On the basis of the above, referring to fig. 3, if it is determined that the target video clip object corresponding to the target video clip is not stored in the preset buffer queue, step S35 is performed. The specific implementation process of steps S31-S34 is described above.
S35, creating a video player instance for the target video clip by using an API provided by a video play library, and obtaining a target video clip object.
In practical application, if the Video clip object of the Video clip played by the user is stored in the preset buffer queue, the Video clip object can be directly called to play, if the user jumps to a certain Video clip to play in the playing process, or if the user plays the Video clip for the first time, there is a situation that the target Video clip object corresponding to the target Video clip is not stored in the preset buffer queue, at this time, the function of creating the Video object by calling the browser is called to perform the instantiation operation, specifically, a Video player instance is created for the target Video clip by using the API provided by the Video player library, so as to obtain the target Video clip object.
S36, playing the video content corresponding to the video playing time point in the target video clip object, and storing the target video clip object into the preset cache queue.
After the target video clip object is created, playing is directly invoked, and the specific playing process is described in the above embodiments.
After the instantiation operation is performed on the target video segment to obtain the target video segment object, the target video segment object may also be stored in a preset buffer queue.
In practical application, there may be a case that a user plays a certain video clip in a loop in order to view the video clip effect, so in order to avoid the need of an instantiation operation when playing the same video clip again, the embodiment stores the target video clip object in a preset buffer queue for the next call.
In addition, after the target video clip object has been stored in the preset cache queue, it is determined whether the video clip object of the video clip adjacent to the target video clip is stored in the preset cache queue.
Specifically, when a user previews a video clip, when playing a certain video clip, the probability of jumping to the next video clip or the previous video clip is extremely high, in order to be suitable for such a scene, if an adjacent video clip object is not stored, an instantiation operation can be performed on a video clip adjacent to a target video clip to obtain an associated video clip object, and the associated video clip object is stored in a preset cache queue, so that when it is determined that the adjacent video clip needs to be played, the associated video clip object corresponding to the adjacent video clip is called from the preset cache queue and played.
It should be noted that if the video clip played by the user is located at the first or last position of the video queue, only one adjacent video clip object may be cached. If the video clip played by the user is not located at the first or last position of the video queue, two adjacent video clip objects can be cached.
If the associated video clip is played later, the associated video clip object can be directly called from the preset cache queue to play, so that the problem of play delay caused by instantiation operation is avoided, and the user experience is improved.
In addition, if the associated video clip object is already stored in the preset cache queue, secondary cache is not performed.
In this embodiment, during the playing process, the video clip currently being played and the video clips before and after the video clip are instantiated and stored in the preset buffer queue, and during the subsequent playing process, whether the video clip to be played exists or not is first seen from the preset buffer queue, so that the time of the instantiation operation is reduced, the video playing waiting time is reduced, and the user experience is improved.
The embodiment reduces the video playing waiting time by performing the instantiation operation in advance, and in addition, the video playing waiting time can be reduced by performing the preloading operation. Specifically, referring to fig. 4, after calling and playing the video content corresponding to the video playing time point from the preset buffer queue, the method further includes:
S45, judging whether the loading of the target video clip object is completed or not; if yes, go to step S46.
Specifically, whether all video clips included in the target video clip object are loaded through a network request is judged.
In the playing process of the target video clip object, the video clips to be played in the target video clip object are sequentially played, and when the current video clip is played, the next clip or a plurality of subsequent video clips are loaded until the last video clip is loaded, and at the moment, the loading of the target video clip object is considered to be completed.
S46, preloading the appointed video segment object.
Specifically, the specified video clip object is a video clip object corresponding to a next video clip located after the target video clip.
That is, after loading the target video clip object, the video clip object corresponding to the next video clip located after the target video clip is preloaded in advance, and when the preloading is performed, a set number of video clips, for example, 3 to 5 video clips, may be preloaded.
In this embodiment, when the preloading operation is performed during the next video clip object to be played, the jump at the video connection position can avoid the condition of blocking, reduce the waiting time of the user during the next video clip playing, and improve the user experience.
It should be noted that, the preloading may be performed during the idle time of playing the video clip object, so as to avoid affecting the clip during playing. In addition, the specific implementation process of steps S41-S44 is described above.
In order that the specific implementation of the present invention may be more clearly understood by those skilled in the art, the description will now be made with reference to steps S51-S510 of fig. 5 and 6.
The timer program detects the video playing time point on the main time axis in real time and transmits the video playing time point to the scheduler program, if the scheduler program determines the target video clip and judges that the video clip object corresponding to the target video clip to be played is stored in the preset cache queue, the video clip object is called from the preset cache queue and played. If not, carrying out instantiation operation on the target video clip in the video queue to obtain a target video clip object, calling and playing, and storing the video clip object in a preset cache queue.
And judging whether the related video segment object is stored in a preset cache queue, if not, creating and storing, if yes, judging whether the loading of the target video segment object is completed, if not, continuing to load, and if so, preloading the next video segment.
For example, five video clips, numbered 1-5, are all on the main timeline, each video clip being ten minutes in length, that total timeline length being 50 minutes. At present, there are 1,2 and 3 video clip objects in the cache queue, and the preset number of the cache queues is 4.
