S201, in an off-line state, the electronic equipment responds to a request playing operation for requesting to play the multimedia resources, and determines target multimedia resources to be played from a plurality of prestored multimedia resources according to the request playing operation.
The multimedia resources are obtained by decompressing prestored multimedia resource compression packets.
As a possible implementation manner, in an offline state, the electronic device obtains a plurality of multimedia resources stored in a memory of the electronic device in response to a request play operation of a user account in a play page, and determines a target multimedia resource from the plurality of multimedia resources according to the request play operation.
It should be noted that the request to play operation includes a first operation and a second operation. The first operation is used for requesting to play the previous multimedia resource, and the second operation is used for requesting to play the next multimedia resource. The electronic device may have stored in a memory a plurality of compressed packets of multimedia assets and a plurality of multimedia assets.
The multimedia asset compression packets include uncompressed multimedia asset compression packets and decompressed multimedia asset compression packets. An uncompressing multimedia asset compression packet is a multimedia asset compression packet that is not uncompressed in the electronic device. The decompressed multimedia resource compression packet is a multimedia resource compression packet that has been decompressed in the electronic device. Each multimedia resource compression packet is obtained based on a plurality of continuous preset multimedia resource compression
For example, the first operation may be a slide-up operation and the second operation may be a slide-down operation. The number of the plurality of multimedia resources pre-stored in the electronic device may be 20, the number of the multimedia resource compression packets pre-stored in the electronic device may be 5, and the number of the multimedia resources compressed in each multimedia resource compression packet may be 10.
In the case that the play request operation is the first operation, the target multimedia resource is the last multimedia resource that has been played.
In this case, after acquiring the plurality of multimedia assets, the electronic device determines a last multimedia asset that has been played from the plurality of multimedia assets, and determines the last multimedia asset as the target multimedia asset.
And under the condition that the playing request operation is the second operation, the target multimedia resource is the next multimedia resource which is not played.
In this case, the electronic device determines a next multimedia asset, which has not been played, from among the plurality of multimedia assets after acquiring the plurality of multimedia assets, and determines the next multimedia asset as the target multimedia asset.
In some embodiments, the multimedia assets include video data, comment information, and description information.
The video data is data used for live broadcasting, the comment information includes comments of the multimedia resources from a plurality of user accounts, and the description information includes description information of the multimedia resources, such as author information and video description.

Therefore, after receiving a play request operation of a user account requesting to play a multimedia resource, the electronic device can directly determine a target multimedia resource from the stored multimedia resources and play the multimedia resource, and can realize the switching of the short video application program and the playing of the video in an off-line state.
In one design, in order to ensure that the multimedia resource stored in the electronic device can meet the playing requirement of the user account, as shown in fig. 3, the method for playing the multimedia resource provided by the embodiment of the present disclosure further includes the following steps S301 to S305:
s301, in an off-line state, the electronic equipment responds to the request playing operation and determines the number of the plurality of multimedia resources.
As a possible implementation manner, after the electronic device receives a play request operation of a user account in an offline state, the electronic device determines the number of the plurality of multimedia resources stored in the electronic device.
In an actual application process, the sequence of S201 and S301 is not limited in the embodiment of the present disclosure.
S302, the electronic device judges whether the number of the plurality of multimedia resources is smaller than a first threshold value.
It should be noted that the first threshold may be preset in the electronic device by the operation and maintenance personnel in advance.
Illustratively, the first threshold may be 10.
S303, under the condition that the number of the plurality of multimedia resources is smaller than a first threshold value, the electronic equipment determines a target multimedia resource compression packet to be decompressed from the uncompressed multimedia resource compression packets.
As a possible implementation manner, in a case that the number of the plurality of multimedia resources is smaller than the first threshold, the electronic device determines an uncompressing multimedia resource compression packet from the multimedia resource compression packets stored in the electronic device, and determines a target multimedia resource compression packet from the determined uncompressing multimedia resource compression packet.
It should be noted that the target multimedia resource compression packet may be any one of the uncompressed multimedia resource compression packets, or may be a next multimedia resource compression packet of the currently uncompressed multimedia resource compression packet.
Illustratively, 5 compressed multimedia resource packets are stored in the electronic device, wherein the first 2 compressed multimedia resource packets are decompressed compressed multimedia resource packets, and the last 3 compressed multimedia resource packets are uncompressed multimedia resource packets. In this case, the electronic device may convert the 3 rd multimedia asset compression packet into the target multimedia asset compression packet.
It should be noted that, in the above example, the sequence of the multimedia resource compressed packets is the same as the sequence of the plurality of multimedia resources. For example, the 1 st pack of multimedia resources comprises the 1 st to 10 th multimedia resources, the 2 nd pack of multimedia resources comprises the 11 th to 20 th multimedia resources, and the 3 rd pack of multimedia resources comprises the 21 st to 30 th multimedia resources.
In some embodiments, in the case that the number of the plurality of multimedia resources is greater than or equal to the first threshold, the electronic device performs S201 described above.
S304, the electronic equipment decompresses the target multimedia resource compression packet to obtain the multimedia resources in the target multimedia resource compression packet.
As a possible implementation manner, the electronic device decompresses the target multimedia resource compression packet to obtain the multimedia resource in the target multimedia resource compression packet.
Taking the above example as an example, the electronic device decompresses the 3 rd multimedia resource compression packet to obtain the 21 st to 30 th multimedia resources included in the 3 rd multimedia resource compression packet.
S305, the electronic equipment stores the multimedia resources in the target multimedia resource compression package.
The technical scheme provided by the embodiment at least has the following beneficial effects: when the multimedia resource currently cached by the electronic equipment is smaller than the first threshold value, the electronic equipment determines the target multimedia resource compression packet, decompresses the target multimedia resource compression packet to obtain the multimedia resource in the target multimedia resource compression packet, stores the multimedia resource, and can ensure that the video is played after the subsequent switching of the user account.
In one design, as multimedia resources stored in the electronic device are more and more, in order to relieve the cache pressure of the electronic device, as shown in fig. 4, the method for playing the multimedia resources provided in the embodiment of the present disclosure further includes the following steps S401 to S402:
s401, in an off-line state, the electronic equipment responds to the request for playing operation and determines a target played multimedia resource from the played multimedia resources.
The difference value between the playing sequence of the played target multimedia resource and the playing sequence of the target multimedia resource is a preset value.
As a possible implementation manner, after receiving the request play operation of the user account and determining the target multimedia resource, the electronic device determines the played multimedia resource stored in the electronic device, and determines the target played multimedia resource from the determined played multimedia resources based on the play order of the played multimedia resource and the play order of the target multimedia resource.
It should be noted that the preset value may be preset in the electronic device by the operation and maintenance staff.
For example, the preset value may be 9. With reference to the above example, the electronic device currently stores 20 multimedia resources, and after the user account performs the play request operation, the electronic device determines that 10 played multimedia resources are included in the currently stored 20 multimedia resources, and the playing order of the target multimedia resource is 10 th. In this case, the electronic device determines that the 1 st played multimedia asset of the 10 played multimedia assets is the target played multimedia asset.
As yet another example, the electronic device determines the played multimedia asset played first (played first) as the target played multimedia asset after determining that the multimedia asset has been played.
S402, the electronic equipment deletes the target played multimedia resource.
Taking the above example as an example, after the electronic device deletes the target played multimedia asset, the user account may look back up a maximum of 9 played multimedia assets through the first operation.
The technical scheme provided by the embodiment at least has the following beneficial effects: after the user account requests to play the video, the target played multimedia resource is determined from the played multimedia resources and the target played multimedia resource is deleted, so that sufficient storage space can be guaranteed to be kept in the electronic equipment. Meanwhile, the difference value between the playing sequence of the played target multimedia resource and the playing sequence of the target multimedia resource is a preset value, so that the situation that a certain amount of played multimedia resources are still stored in the electronic equipment can be ensured, and the requirement of a user account for reviewing short videos can be met.
In one design, in order to satisfy an offline request of a user account when the user account logs in a short video application program for the first time and requests to play a first video in an offline state, as shown in fig. 5, the method for playing a multimedia resource provided in the embodiment of the present disclosure further includes the following steps S501 to S503.
S501, in an off-line state, the electronic device responds to the first request playing operation and determines a target multimedia resource compression packet to be decompressed from the prestored multimedia resource compression packets.
As a possible implementation manner, after receiving a first play request operation of a user account, the electronic device determines, based on a decompression order of the compressed multimedia resource packets, a target compressed multimedia resource packet to be decompressed from the compressed multimedia resource packets.
It should be noted that, when the user account performs the first request play operation in the electronic device, the electronic device stores a plurality of multimedia resource compressed packets, but does not store any multimedia resource. The decompression sequence is the sequence of the decompression of the multimedia resource compressed packet. The decompression sequence is associated with a play sequence of the multimedia asset.
In some embodiments, the target compressed multimedia resource packet may be any one or more compressed multimedia resource packets, may also be a first compressed multimedia resource packet stored in the electronic device, and may also be the first n compressed multimedia resource packets stored in the electronic device. n is a positive integer less than the number of compressed packets of the multimedia resource.
Illustratively, 5 compressed packets of multimedia resources are stored in the electronic device. The 1 st media resource compression packet with the decompression sequence 1 comprises 1 st to 10 th multimedia resources, the 2 nd media resource compression packet with the decompression sequence 2 comprises 11 th to 20 th multimedia resources, the 3 rd media resource compression packet with the decompression sequence 3 comprises 21 rd to 30 th multimedia resources, and so on. In this case, the electronic device may use the 1 st and 2 nd multimedia resource compression packets as the target multimedia compression packet.
S502, the electronic equipment decompresses the target multimedia resource compression packet to obtain the multimedia resources in the target multimedia resource compression packet.
Taking the above example as an example, in the case that the electronic device takes the 1 st and 2 nd compressed packets of the multimedia resource as the compressed packets of the target multimedia resource, the electronic device obtains the 1 st to 10 th multimedia resources and the 11 th to 20 th multimedia resources after decompressing the compressed packets of the target multimedia resource.
S503, the electronic equipment stores the multimedia resources in the target multimedia resource compression package.
The technical scheme provided by the embodiment at least has the following beneficial effects: when a user account logs in a short video application program for the first time in an offline state, the pre-stored target multimedia resource compression packet is decompressed, and multimedia resources in the target multimedia resource compression packet are stored, so that a first playing request of the user account in the offline state is met.
In one design, in order to further ensure that a sufficient storage space is reserved in the electronic device, the method for playing the multimedia resource provided by the embodiment of the present disclosure further includes the following step S601.
S601, after decompressing the target multimedia resource compression packet, the electronic device deletes the target multimedia resource compression packet.
As one possible implementation, the electronic device deletes the target compressed multimedia asset packet from the memory of the electronic device after determining that the target compressed multimedia asset packet has been decompressed.
In some embodiments, this step may be performed after S304 or S502 described above, respectively.
Illustratively, after the electronic device decompresses the 1 st and 2 nd compressed multimedia resource packets, the 1 st and 2 nd compressed multimedia resource packets are deleted.
The technical scheme provided by the embodiment at least has the following beneficial effects: after the target multimedia compression packet is decompressed, the target multimedia resource compression packet is deleted in time, so that sufficient storage space can be further ensured to be reserved in the electronic equipment.
In one design, in order to enable the electronic device to store the compressed multimedia resource package in advance, as shown in fig. 6, the method for playing the multimedia resource provided in the embodiment of the present disclosure further includes the following steps S701 to S703:
s701, in an online state, the electronic equipment acquires a plurality of preset multimedia resources.
And the total playing time of the preset multimedia resources is less than a second threshold value.
As a possible implementation manner, the electronic device may obtain a plurality of preset multimedia resources from the server in an online state.
It should be noted that the second threshold may be set in the electronic device by the operation and maintenance personnel in advance.
In some embodiments, the predetermined multimedia resources may also be a certain number of multimedia resources.
S702, the electronic device compresses a plurality of preset multimedia resources into a plurality of multimedia resource compression packets.
Wherein, each multimedia resource compression packet comprises a preset number of continuous preset multimedia resources.
As a possible implementation manner, the electronic device may compress a plurality of preset multimedia resources into a plurality of multimedia resource compression packets in segments according to the playing order and the preset number.
For example, the electronic device may sequence a plurality of preset multimedia resources according to the playing sequence, compress the 1 st to 10 th multimedia resources into the 1 st multimedia resource compression packet, compress the 11 th to 20 th multimedia resources into the 2 nd multimedia resource compression packet, and so on, until a plurality of multimedia resource compression packets are obtained.
S703, the electronic equipment stores a plurality of multimedia resource compression packets.
The technical scheme provided by the embodiment at least has the following beneficial effects: the acquired preset multimedia resources are compressed into a plurality of multimedia resource compression packets in a segmented manner, so that flexible storage of the multimedia resources and pre-decompression in subsequent sliding switching can be realized.
