In the video platform, a user can upload a shared video file to the video platform for sharing.

Fig. 1 schematically shows an environment architecture diagram of an embodiment of the present application, as shown in fig. 1:
a user of a client 301 uploads a multimedia file to be audited to a server 100 through a network 200 for transcoding and auditing, the client 302 acquires the multimedia file to be audited from the server 100 through the network 200 for auditing, a result is sent to the server 100 after auditing is finished, after transcoding and auditing of the multimedia file are both finished, the user of the client 303 can send a request for applying for playing the audited multimedia file to the server 100 through the network 200, and the server 100 transmits the audited multimedia file to the client 303 through the network 200 for playing according to the request, wherein the multimedia file can be a file such as audio, video and the like which needs transcoding; the client 302 may specifically be a client of the auditing platform, and the server 100 may specifically be a multimedia platform (e.g., a video platform). It should be noted that, a user of the client 301 may also send a request for applying for playing the audited multimedia file to the server 100 through the network 200, and the server 100 may also transmit the audited multimedia file to the client 301 through the network 200 for playing according to the request of the client 301, but in order to more clearly reflect the uploading, auditing and playing processes of the multimedia file, an interaction process with the server 100 and the network when the client 301 requests to play the multimedia file is not shown in fig. 1. In addition, the transcoding process of the multimedia file may be performed in the server 100, or may be performed by another system connected to the server 100. If a machine automatic review mode is adopted, the server 100 may also automatically review the multimedia files uploaded by the client 301.
In an exemplary embodiment, the server 100 may index a data center, such as a single house, or be distributed over different geographic locations (e.g., over several houses). The server 100 may provide services through one or more networks 200. Network 200 includes various network devices such as routers, switches, multiplexers, hubs, modems, bridges, repeaters, firewalls, proxy devices, and/or the like. Network 200 may include physical links such as coaxial cable links, twisted pair cable links, fiber optic links, combinations thereof, and/or the like. The network 200 may include wireless links, such as cellular links, satellite links, Wi-Fi links, and/or the like. Clients 301, 302, or 303 may include devices such as mobile devices, tablet devices, laptop computers, smart devices (e.g., smart apparel, smart watches, smart glasses), virtual reality headsets, gaming devices, set-top boxes, digital streaming devices, robots, vehicle terminals, smart televisions, television boxes, or e-book readers.
In the related art, when the multimedia file is checked, the checking is generally performed according to the sequence of the uploading completion time of the multimedia file. However, due to factors such as format, length, definition, and frame rate, the time duration required for transcoding different multimedia files is very different, so the following two situations can be caused when the multimedia file is audited according to the first-in first-out principle:
(1) although some multimedia files have been transcoded, the multimedia files still need to wait for a long time to be checked because the uploading is completed later, and the process is schematically shown in fig. 2.
(2) Although some multimedia files are not transcoded, the uploading is completed earlier and the auditing is completed, but the transcoding needs to be completed waiting for completion, and the process diagram is shown in fig. 3.
It can be seen that, in the multimedia file in the case (2), since the transcoding takes a long time, there is no need to complete the auditing earlier, and the auditing resource in this case should be preferentially used to audit the multimedia file in the case (1), so that the multimedia file can be audited immediately before, just after, or shortly after the transcoding is completed, and there is no need to wait for a long time in a queue to audit; after the multimedia file in the (1) th situation is audited, the multimedia file in the (2) th situation is audited, so that transcoding is finished, just finished or finished when auditing is finished, and the transcoding process is not required to be published for a long time, and therefore both situations can cause the waste of auditing resources.
The multimedia file processing scheme provided by the application can reduce the waste of auditing resources, realize the optimization of the processes of multimedia transcoding and auditing and improve the utilization efficiency of auditing resources.
The multimedia file processing scheme of the present application will be described below by way of several embodiments.
Example one
Fig. 4 schematically shows a flowchart of a multimedia file processing method provided in an embodiment of the present application. It should be noted that an execution subject of the multimedia file processing method provided in the first embodiment of the present application may be the server 100 in fig. 1, or may also be the client 302 in fig. 1, which will be described in detail later. As shown in fig. 4, the multimedia file processing method may include:
and step S1, determining the target transcoding time of each multimedia file to be audited.
In an exemplary embodiment, step S1 may include: and acquiring the estimated transcoding completion time of each multimedia file to be audited, and taking the estimated transcoding completion time as the target transcoding time of the multimedia file.
For example, if the estimated transcoding completion time of the multimedia file a is a, a is taken as the target transcoding time of the multimedia file a.
When the estimated transcoding completion time of each multimedia file to be audited is obtained, each multimedia file to be audited can be estimated manually according to practical experience, and can also be obtained from a transcoding system of the multimedia file. The transcoding system can abstract and fit the time length required by transcoding in a machine learning mode according to the format, code rate, definition, transcoding difficulty and the like of the multimedia file, so that the estimated transcoding completion time of the multimedia file can be output by combining the current time after the multimedia file is obtained. For example, if the transcoding system estimates that the time required for transcoding a certain multimedia file is 10 minutes, the estimated transcoding completion time of the multimedia file can be output as the current time plus 10 minutes.
The actual transcoding completion time of the multimedia file is unknown before the transcoding is finished, and the estimated transcoding completion time can better reflect the actual transcoding completion time, so that the estimated transcoding completion time of the multimedia file is used as the target transcoding time, a good sequence basis can be provided for the auditing of the multimedia file, the auditing and the transcoding of the multimedia file can be finished at a relatively close time point, and the time for waiting for the auditing to be finished or the transcoding to be finished is reduced.
In an exemplary embodiment, step S1 may further include: and under the condition that the multimedia file is a timed task, acquiring timed release time of the multimedia file, and taking the timed release time as target transcoding time of the multimedia file.
The timed release time can be set by an uploading user of the multimedia file, and after the uploading user sets the timed release time, the server 100 can mark the timed release time as a timed task, so that whether the multimedia file is the timed task can be determined according to the mark; and under the condition that the multimedia file is determined to be a timing task, acquiring timing release time.
It can be understood that if the multimedia file is not a timed task, the target transcoding time should be closely related to the time required for transcoding the multimedia file; however, if the multimedia file is a timed task, the target transcoding time has little relation with the time required by transcoding of the multimedia file, for example, the time required by transcoding of the multimedia file may be 5 minutes, and the timed release time is released after 2 hours of the current time. Therefore, if the audit sequence is determined according to the estimated transcoding completion time of the multimedia file which is a timing task, a result that the multimedia file can be transcoded after waiting for a long time after the audit is completed occurs, and therefore, audit resources are wasted.
By acquiring the timed release time of the multimedia file and taking the timed release time as the target transcoding time of the multimedia file, the target transcoding time can reflect the actual transcoding completion time of the multimedia file serving as a timed task, and good sequential basis is provided for the auditing of the multimedia file, so that the auditing and transcoding of the multimedia file can be finished at relatively close time points, the time for waiting for the auditing to be finished or the transcoding to be finished is reduced, and the waste of auditing resources is reduced.
And step S2, determining the weight of the multimedia file according to the target transcoding time, adding the multimedia file into a scheduling queue, wherein the weight determines the position of the multimedia file in the scheduling queue, and the weight can be dynamically adjusted.
When the weight of the multimedia file is determined according to the target transcoding time, the target transcoding time can be directly used as the weight of the multimedia file, and because the target transcoding time has a sequence, the weight of each multimedia file is different due to the difference of the sequence of the target transcoding time, so that the positions of the multimedia file in a scheduling queue are different; if the target transcoding time of some multimedia files is the same, the positions of the multimedia files in the scheduling queue can be randomly determined when the multimedia files are added into the scheduling queue. Optionally, the target transcoding time may also be adjusted or transformed according to a preset rule, and the adjusted or transformed target transcoding time is used as a weight of the multimedia file. The preset rule may be set according to actual needs, and is not limited here.
If the sequence of the scheduling queue is in a sequence from big to small according to the weight, when the weight of the multimedia file is determined according to the target transcoding time, the weight of the multimedia file with the earlier target transcoding time is larger, and the weight of the multimedia file with the later target transcoding time is smaller, because the target transcoding time reflects the actual transcoding completion time of the multimedia file, when the target transcoding time is earlier, the actual transcoding completion time of the multimedia file is indicated to be earlier, and in order to reduce the time for waiting for auditing after the transcoding is completed, the multimedia file is audited earlier, so the weight of the multimedia file is larger; when the target transcoding time is later, the actual transcoding completion time of the multimedia file is later, in order to reduce the time for waiting for transcoding after auditing, the multimedia file should be audited later, and therefore the weight of the multimedia file is smaller. Correspondingly, if the sequence of the scheduling queue is in the order from small to large according to the weight, when the weight of the multimedia file is determined according to the target transcoding time, the weight of the multimedia file with the earlier target transcoding time is smaller, and the weight of the multimedia file with the later target transcoding time is larger.
When adding a multimedia file into the scheduling queue, the weight of the multimedia file to be added may be compared with the weight of the multimedia file already in the scheduling queue, thereby determining the position of the multimedia file to be added in the scheduling queue. After the multimedia files are added into the scheduling queue, the weight of a certain multimedia file can be dynamically adjusted according to actual needs, so that the position of the multimedia file in the scheduling queue is changed, and the checked sequence of the multimedia file is adjusted.
It can be understood that the multimedia files include multimedia files with longer duration and multimedia files with shorter duration (such as long video files and short video files), and the multimedia files with longer duration are generally longer in transcoding time due to more contents; since the content of the multimedia file with a shorter duration is less, the transcoding time is generally shorter, and therefore, if the multimedia file with a shorter duration is too many, the auditing of the multimedia file with a longer duration may be affected. Therefore, when the multimedia files are added into the scheduling queues, the multimedia files can be classified according to time length, and the multimedia files of different types are added into different scheduling queues, so that the influence of excessive multimedia files with short time length on the auditing of multimedia files with long time length can be avoided. Optionally, other classification audits may be performed on the multimedia file, and the settings may be specifically performed according to actual needs, which is not limited here.
And step S3, acquiring the multimedia file from the scheduling queue for auditing.
As described above, an execution main body of the multimedia file processing method provided in the embodiment of the present application may be the server 100 in fig. 1, and the specific execution process is, for example: after receiving the multimedia file to be audited, the server 100 acquires the estimated transcoding completion time of the multimedia file from the transcoding system, and takes the estimated transcoding completion time as target transcoding time; and then determining the weight of the multimedia file according to the target transcoding time, adding the multimedia file into a scheduling queue according to the weight of the multimedia file, and finally acquiring the multimedia file from the scheduling queue according to the position sequence for auditing. When acquiring the multimedia file from the scheduling queue for auditing, the server 100 may send the multimedia file acquired from the scheduling queue to an auditing platform, and the auditing platform audits the multimedia file, where in this case, step S3 may be: and acquiring the multimedia file from the scheduling queue, and sending the acquired multimedia file to an auditing platform for auditing. The specific implementation process is, for example: the server 100 acquires the multimedia file from the scheduling queue, sends the acquired multimedia file to the client 302 (client of the auditing platform) through the network 200, and the client 302 audits the multimedia file. Optionally, an execution main body of the multimedia file processing method provided in this embodiment of the present application may also be the client 302 in fig. 1, and a specific execution process is, for example: the client 302 acquires the estimated transcoding completion time of the multimedia file from the transcoding system as target transcoding time, then determines the weight of the multimedia file according to the target transcoding time, puts the multimedia file into a scheduling queue according to the weight of the multimedia file, and acquires the multimedia file from the scheduling queue for auditing. In addition, when the multimedia file is audited by the auditing platform, the multimedia file can be audited manually by staff of the auditing platform.
In the related technology, the verification is performed according to the sequence of the uploading completion time of the multimedia file, so that the condition that the difference between the transcoding completion time and the verification completion time is relatively long easily occurs; in the multimedia file processing method provided in the embodiment of the present application, the weight is determined according to the target transcoding time of the multimedia file, the position of the multimedia file in the scheduling queue (that is, the order of the auditing) is determined according to the weight, and the target transcoding time reflects the actual transcoding completion time of the multimedia file, so that the auditing completion time and the transcoding completion time of the multimedia file can be relatively close to each other, and a schematic process diagram of the process is shown in fig. 5, that is, the auditing can be performed when the multimedia file completes most of the transcoding process, so that the time points of the auditing and the transcoding completion time are close to each other.
The multimedia file processing method provided by the first embodiment of the application determines the target transcoding time of each multimedia file to be audited, determines the weight of the multimedia file according to the target transcoding time, and adds the multimedia file into the scheduling queue, wherein the weight determines the position of the multimedia file in the scheduling queue, and the weight can be dynamically adjusted, acquires the multimedia file from the scheduling queue for auditing, because the target transcoding time can better reflect the actual transcoding completion time of the multimedia file, determines the weight of the multimedia file according to the target transcoding time, determines the position of the multimedia file in the scheduling queue according to the weight, and finally acquires the multimedia file from the scheduling queue for auditing, the transcoding completion time point of the multimedia file can be as close as possible to the auditing completion time point, and the time waiting for auditing or transcoding completion can be reduced, therefore, the waste of audit resources is reduced, the transcoding and audit processes are optimized, and the utilization efficiency of the audit resources is improved; meanwhile, the weight of the multimedia file is obtained on the basis of the target transcoding time, so that the auditing sequence can be properly adjusted according to actual needs on the basis of the target transcoding time, and the auditing mode is more flexible.
In an exemplary embodiment, the multimedia file processing method provided in the first embodiment of the present application may further include: and under the condition that the transcoding of the multimedia file is finished and the transcoded multimedia file is not checked, adjusting the weight of the transcoded multimedia file.
The position of the transcoded multimedia file in the scheduling queue can be changed by adjusting the weight of the transcoded multimedia file, so that the position of the transcoded multimedia file in the scheduling queue is changed, the auditing sequence is advanced, and the time for waiting for auditing and ending auditing after transcoding is finished is reduced.
In an exemplary embodiment, as shown in fig. 6, step S2 may include:
step S21, converting the target transcoding time into a first long integer.
Specifically, it may be time to convert the target transcoding time into an integer form, thereby obtaining a first long integer. For example, if the target transcoding time of a multimedia file is 20 o' clock 30 min 30 s of 11/month 30/year 2021, the target transcoding time may be converted into a format of "yyymmddhhmmss", that is, a format of "yearly, month, day, hour, minute and second", and the first long integer is 20211130203030. The integer form of conversion may be set according to actual needs, for example, conversion may also be "year, month, day, time, minute and second", and the like, and is not limited specifically here.
And step S22, obtaining the weight of the multimedia file according to the first long integer.
Specifically, the first long integer may be used as the weight of the multimedia file, or the first long integer may be adjusted to a certain degree, and the adjusted first long integer may be used as the weight of the multimedia file. For example, a value is subtracted from or added to the first long integer, or the first long integer is multiplied by a ratio, and the like, and the specific adjustment manner may be set according to the actual needs, and is not limited herein.
The target transcoding time is converted into a first long integer, and the weight of the multimedia file is obtained according to the first long integer, so that the position of the multimedia file in the scheduling queue can be determined conveniently by sorting the weight of the multimedia file in size in the follow-up process; meanwhile, the weight of the multimedia file is obtained according to the first long integer, and the position of the multimedia file in the scheduling queue can be adjusted according to actual needs, so that the auditing sequence of the multimedia file is adjusted, and the flexibility of adjusting the auditing sequence is improved.
In an exemplary embodiment, as shown in fig. 7, step S22 may further include:
step S221, the basic weight of the multimedia file is obtained according to the first long integer.
Specifically, the first long integer may be directly used as the basic weight of the multimedia file, or may be subjected to other processing, and the processed first long integer may be used as the basic weight of the multimedia file.
Step S222, adjusting the basic weight according to the attribute of the multimedia file to obtain the weight of the multimedia file.
The attributes of the multimedia file may include inherent attributes such as file format, file length, definition, frame rate, and bit rate, and the inherent attributes of each multimedia file may be different, so the basic weight of each multimedia file may be adjusted according to the inherent attributes, and the specific adjustment mode may be set according to actual needs, which is not limited herein. For example, if the multimedia files are not classified according to the file length (duration) before the auditing, the basic weight of the multimedia files with longer duration can be properly reduced, so that the auditing priority degree is properly improved; meanwhile, the basic weight of the multimedia file with shorter time is properly increased, so that the auditing priority degree of the multimedia file is properly reduced.
The attributes of the multimedia file may further include service attributes such as a user attribute (e.g., a designated user or an old user), a source attribute (e.g., a designated source), and a service type (e.g., a type of life, current affairs, or technology), and since the service attributes of different multimedia files may also be different, the basic weight may also be adjusted according to the service attributes, and a specific adjustment manner is not limited here. For example, if a multimedia file is uploaded by an old user, the basic weight of the multimedia file can be appropriately reduced, so that the auditing priority of the multimedia file can be appropriately improved.
The basic weight of the multimedia file is obtained through the first long integer, and then the basic weight is adjusted according to the attribute of the multimedia file to obtain the weight of the multimedia file.
In an exemplary embodiment, as shown in fig. 8, step S221 may further include:
and step S2211, adding adjusting bits in front of and/or behind the first long integer, wherein the adjusting bits comprise a plurality of digits.
Please refer to fig. 9, which is a schematic diagram of adding the adjustment bits based on the first long integer, as shown in fig. 9, the target time factor corresponds to the first long integer, which is determined by the target transcoding time and other factors, and a priority adjustment bit is added in front of the first long integer, where the priority adjustment bit includes two bits; and an adjusting bit of the sorting parameter is added behind the first long integer, and the adjusting bit also comprises two digits. The adjustment bit of the priority is at the top, and the size of the second long integer is most easily determined, so that the adjustment bit can be used for realizing large-amplitude adjustment of the position (namely, the audit sequence) of the adjustment bit in the scheduling queue; the adjustment bits of the sorting parameters have a small influence on the size of the second long integer due to the rearmost position, and therefore, the adjustment bits can be used for performing small-amplitude adjustment on the positions (namely, the audit sequence) of the preceding integers in the scheduling queue at the same time, and the two adjustment bits are two different-amplitude adjustments. It should be noted that the two-digit adjustment bits shown in fig. 9 are only examples, and are not limited to the adjustment bits comprising the number of bits, and here the second long integer composed of the adjustment bits (4 bits in total) and the first long integer (14 bits) is 18 bits, which is a factor combining the requirements of computer storage. In fact, the number of the adjusted bits may be other bits, and only needs to meet the requirement of computer storage, which is not limited herein.
And step S2212, forming a second long integer by the adjusting bit and the first long integer, and taking the second long integer as the basic weight of the multimedia file.
The adjustment bits are added in front of and/or behind the first long integer, then the adjustment bits and the first long integer form a second long integer, and the second long integer is used as the basic weight of the multimedia file.
In an exemplary embodiment, on the basis of the foregoing embodiment, the step S222 (i.e. adjusting the basic weight according to the attribute of the multimedia file to obtain the weight of the multimedia file) may further include: and adjusting the adjusting bit and/or the first long integer in the basic weight according to the attribute of the multimedia file to obtain the weight of the multimedia file.
That is, when the basic weight is adjusted according to the attribute of the multimedia file, the adjustment bit can be adjusted according to the attribute of the multimedia file. For example, the adjustment bits of the priority are adjusted, so that the multimedia files uploaded by the old users can be audited more preferentially. For another example, the adjustment bits of the sorting parameters of a plurality of multimedia files which are uploaded by the same uploading user at the same time and have a sequence are adjusted, so that the auditing sequence conforms to the sequence of the auditing user. Optionally, the first long integer may also be adjusted according to the attribute of the multimedia file, and the adjustment bit and the first long integer may also be adjusted simultaneously, so that the audit sequence meets the actual requirement.
Because the multimedia files have various different attributes, the attributes of different multimedia files are different, and the adjustment bits and the first long integer in the basic weight can be adjusted in different degrees or different rules, the adjustment bits and/or the first long integer in the basic weight can be adjusted according to the attributes of the multimedia files, so that various adjustment requirements of the multimedia files can be met, and the adjustment flexibility of the auditing sequence is improved.
In an exemplary embodiment, on the basis of the foregoing embodiment, the adjusting the weight of the transcoded multimedia file may include: adjusting an adjustment bit and/or a first long integer in the weight of the transcoded multimedia file.
Since the transcoded multimedia file needs to be audited quickly, the adjustment bits of the priority in the weight can be adjusted, so that the audited sequence is greatly accelerated; or adjusting the adjusting bits in the weights and the first long integer at the same time, for example, zeroing the adjusting bits and the first long integer at the same time so that they are audited immediately; the adjustment bit and/or the first long integer can also be adjusted according to a certain rule, so that the audited sequence of other multimedia files is properly accelerated on the premise of not causing great influence on the other multimedia files, and the specific rule can be set according to actual needs, and is not limited here.
By adjusting the adjusting bits and/or the first long integers in the weight of the transcoded multimedia files, the auditing sequence of the transcoded multimedia files can be accelerated to different degrees, and the time for waiting for auditing and ending auditing is shortened.
In an exemplary embodiment, adjusting the first long integer and/or the adjustment bits in the weights of the transcoded multimedia file may include: and acquiring the actual transcoding completion time of the transcoded multimedia file, regenerating a first long integer according to the actual transcoding completion time, and obtaining the weight of the transcoded multimedia file according to the regenerated first long integer.
The target transcoding time of the transcoded multimedia file may be inaccurate, so that the target transcoding time is later than the actual transcoding completion time of the transcoded multimedia file, the first long integer is regenerated according to the actual transcoding completion time, the weight of the transcoded multimedia file is obtained according to the regenerated first long integer, the regenerated weight is smaller than the original weight, and the auditing priority of the transcoded multimedia file can be properly improved. When the weight of the transcoded multimedia file is obtained according to the regenerated first long integer, the adjusting bit can be adjusted while the first long integer is regenerated, so that the auditing sequence of the transcoded multimedia file can be further adjusted, and the auditing priority of the transcoded multimedia file can be further changed.
