It should be noted that the scene schematic diagram of the multimedia playing system shown in fig. 1 is only an example, and the multimedia playing system and the scene described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not form a limitation on the technical solution provided in the embodiment of the present application.

The following are detailed below.

In this embodiment, a multimedia playing apparatus will be described in terms of the multimedia playing apparatus, which may be specifically integrated in a terminal, for example, a terminal such as a server, a tablet computer, a mobile phone, a notebook computer, a server, a wearable smart device, and the like, which has a storage unit, is installed with a microprocessor, has computing capability, and is capable of playing multimedia.

As shown in fig. 2, fig. 2 is a schematic flowchart of a multimedia playing method according to an embodiment of the present application.

The multimedia playing method can comprise the following steps:

101. and playing the multimedia according to an index file of the multimedia, wherein the index file comprises a first mapping relation between a first multimedia fragment identifier and a playing time period and a second mapping relation between at least one second multimedia fragment identifier and the playing time period.

The multimedia may be in various media forms including text, images, sounds, etc., the multimedia may be displayed and information exchanged on the terminal using more than one media form, for example, the multimedia may include movies, advertisement videos, art programs, songs, radio broadcasts, or audio books, etc., and the multimedia may also include electronic invitations, podcasts, broadcast plays, etc.

The index file of the multimedia can be determined based on the way of playing the multimedia and the number of bytes occupied by the multimedia, and the index file is usually required to be acquired when the multimedia is acquired in a live broadcast or on demand way through a network. And the number, format and form of the index files are different with different transmission modes of the multimedia.

For example, if multimedia playing is performed in an on-demand manner based on the mpeg fourth generation protocol standard (MP4 protocol, Moving picture experts Group 4), the index file may be composed of a plurality of boxes (boxes), each box is composed of a header (header) and data (data), and the boxes carry different data and have different functions, for example, a box containing metadata (metadata may describe data) and a box containing actual data (actual data is multimedia data for playing).

For another example, if the multimedia playing is performed in an on-demand or live broadcast manner based on the streaming media network transport protocol (HLS) of the request-response protocol, the form of the index file may be a website, and the index file may include a plurality of total features (such as an identifier of the index file) and a plurality of segment identifiers and their features (such as an actual duration of the segments). The index files can be nested, for example, one index file can contain a plurality of overall features and a plurality of lower-level index files (such as a second-level index file, a third-level index file and the like). The number of index files required by a multimedia is not fixed, and can be flexibly set according to actual requirements and application scenarios, for example, for a multimedia (e.g., audio 1 and video 1) containing two media forms, a first-level index file may contain two second-level index files, each second-level index file contains a playing data identifier and its characteristics of a media form, or two first-level index files, each first-level index file contains a playing data identifier and its characteristics of a media form. And the index file does not contain actual playing data, but only contains content such as configuration information and playing data identifiers, and if the playing data needs to be acquired, the content contained in the index file needs to be further analyzed and processed, for example, the playing data identifiers contained in the index file are processed to acquire the playing data.

The first mapping relationship may be a relationship between the first multimedia segment identifier and the playing time period, and the second mapping relationship may be a relationship between the first multimedia segment identifier and the playing time period. The fragment identifier may be represented in the form of numbers, symbols, or the like, the form of a group of fragment identifiers may include certain sequence information, each fragment identifier may represent different playing data, a fragment identifier includes the actual duration of the playing data represented by the fragment, and the playing time period of the playing data represented by each fragment identifier in the group including the fragment identifier may be determined based on the sequence information included in the group of fragment identifiers to which the fragment identifier belongs and the actual duration of each fragment identifier in the group, that is, a fragment identifier corresponds to a playing time period, so that the mapping relationship between the fragment identifier and the playing time period in the group may be obtained. If a multimedia needs multiple media forms (such as image, audio, and text) or multiple media forms (such as audio 1, audio 2, audio 3, and text 1), a mapping relationship between the multimedia fragment identifier of the fragment identifier group corresponding to each media form and a playing time period is needed.

Specifically, the obtaining of the index file of the multimedia may be sending an index file obtaining request to a server on the network, and receiving the index file returned by the server based on the obtaining request, because the general memory of the server is huge, the selection range of the index file obtained in this way is large, and the selection range of the multimedia data that can be played is large, for example, multimedia data such as online playing video, song, etc. may obtain the index file in this way; the method does not need to be connected with a network, can be used under the offline condition, saves network resources, is suitable for special conditions, for example, under the condition of no network or network impermissibility, multimedia data such as songs and the like can be directly obtained through the database stored on the terminal; the index file acquisition can also be carried out in an intranet, the method is suitable for special groups and special multimedia files, and meets the requirements of confidentiality and the like, for example, video or audio multimedia data related to trade secrets and the like, the index file acquisition can be carried out in a limited range to acquire the multimedia data, and the like.

The multimedia index file and the mapping relation contained in the index file are necessary contents for multimedia playing and skip playing, the multimedia can be played through the multimedia index file, and skip playing can be performed based on the information such as the mapping relation, fragment identification and the like in the index file.

For example, audio a contains audio 1, audio 2, and text 1, for a total of three media forms. The three media formats are configured with three index files, respectively. The terminal sends request information to the server and receives the audio 1 index file, the audio 2 index file and the character 1 index file sent by the server. The audio 1 index file comprises a mapping relation 1 between a first audio fragment identifier and a playing time period, the audio 2 index file comprises a mapping relation 2 between a second audio fragment identifier and a playing time period, and the character 1 index file comprises a mapping relation 3 between a first character fragment identifier and a playing time period.

Specifically, the multimedia can be played through a player, the playing mode is related to the content of the index file, the multimedia can be played through a local player, or played through a player applied to the internet, the index file can request a server or other databases for playing data according to a fragment identifier, a mapping relation and the like contained in the index file, the playing data is obtained, and the multimedia is played according to the playing data.

For example, audio a is played according to an audio 1 index file, an audio 2 index file and a text 1 index file, and a is played through an online application S (an online application is an application that needs to be networked for use).

102. And when a jump playing instruction is received, acquiring a jump time point of the multimedia.

The jumping time point may be a time point at which the multimedia is about to jump to play, and a multimedia data being played needs to change a current playing state due to a user's personal desire or a requirement of an actual application scene, so that the multimedia data starts to be played from another time point, which is the jumping time point. The skip playing instruction is a starting point for determining to execute a skip playing operation on the multimedia data being played, and the skip playing instruction can be input from the outside, can be automatically triggered by a terminal according to a predetermined program, and the like. The jump playing instruction can carry a jump time point and can also be independent from the jump time point.

Specifically, the jumping time point may be obtained based on an external input, for example, by receiving a user input, or generated and input to the multimedia being played by a third-party application; or calling from a locally stored database, for example, calling a jump time point from a locally stored database in advance through a preset script or other forms based on special requirements such as testing; the skip time point sent by the server may also be obtained by the server, for example, based on the self-demand of the application executing the playing multimedia or the characteristics of the multimedia, and the application may receive the skip time point sent by the server, and so on.

The multimedia jump time point is the basis for the multimedia jump playing and is the basis for realizing the jump playing, and the scheme is based on the jump time point and the index file so as to improve the multimedia playing effect.

For example, the current playing time point of the audio a is 1 minute 20 seconds, the current user profile of the playing audio a shows that the user small P is 13 years old because the audio file of 1 minute 21 seconds to 1 minute 29 seconds has the audio content which is not 18 years old and is forbidden to be obtained, so the server sends the jump time point to the application OO used by the small P according to the analysis of the small P and the small a, and the application OO obtains the jump time point sent by the server for 1 minute 31 seconds when receiving the jump playing instruction of the server.

103. And determining the target multimedia identification based on the first mapping relation and the jumping time point.

The target multimedia identifier may belong to the first multimedia fragment identifier, and the target multimedia identifier may represent multimedia data to be played after the jump. According to the difference of multimedia, the media form of the playing data represented by the target fragment identifier may be different, for example, if the multimedia is a movie containing audio 1, video 1, and subtitle 1, the media form represented by the target multimedia identifier may be video 1; if the multimedia is a broadcast play containing audio 1 and audio 2, the target multimedia identifier may represent the media in audio 1, and so on.

The target multimedia identifier is a key point for realizing the completion of the skip playing of the media form corresponding to the first multimedia fragment, the playing data corresponding to the skip time point is a subset of the playing data represented by the target multimedia identifier, and the determination of the target multimedia identifier means the determination of the skip playing of the media form.

For example, the audio 1 index file includes 7 segment identifiers, which are segment 11, segment 12, segment 13, segment 14, segment 15, segment 16, and segment 17. And determining the target multimedia identifier in the audio 1 index file as a fragment 13 through an audio 1 mapping relation (the mapping relation between the audio 1 fragment identifier and the playing time point is called as an audio 1 mapping relation) and a jumping time point (1 minute 31 seconds).

In an embodiment, determining the target multimedia identifier based on the first mapping relationship and the jumping time point may include the steps of: and determining a target playing time period to which the jumping time point belongs, and determining a target multimedia identifier corresponding to the target playing time period based on the first mapping relation.

The playing time period may be a set including a plurality of time points, and the playing time period may be expressed as a set including a different number of time points according to different measurement accuracies, for example, if 1 second is used as an accuracy unit, 1 minute may be a set including 60 time points; if 5 seconds is the precision unit, 1 minute may be a set containing 20 time points. In an actual application scene, a precision unit can be flexibly selected according to the precision of a jump time point, actual requirements and the like, and only the precision of a time point set of a playing time period is required to be ensured to cover the jump time point, and at the moment, a target playing time period to which the jump time point belongs is confirmed, namely, a playing time period corresponding to a time point set to which time points with equal jump time points exist, namely the target playing time period is confirmed; the playing time period may also be two time points, namely, a starting time point and an ending time point, and the target playing time period to which the jumping time point belongs is determined at this time, namely, the playing time period corresponding to the jumping time point is determined to be greater than or equal to the starting time point and less than or equal to the ending time point, namely, the target playing time period.

The first mapping relationship is the relationship between the first multimedia fragment identifier and the playing time period, that is, each fragment identifier in the first multimedia fragment identifier corresponds to a playing time period, and in the mapping relationship, the corresponding fragment identifier can be confirmed by the playing time period, and vice versa. Then in this embodiment, the target multimedia id may be confirmed according to the first mapping relationship and the target playing time point.

104. And determining a target time point of the target multimedia data according to the target multimedia identifier, wherein the target multimedia data corresponds to the target multimedia identifier.

The target multimedia data corresponds to a target multimedia identifier, i.e. data actually played, and the target multimedia data may correspond to a media format of the target multimedia identifier, for example, if the target multimedia identifier is a slice 5 under the video 1 index file, the target multimedia data may be a video segment 55; the target multimedia is identified as slice 2 under the audio 1 index file, the target multimedia data may be an audio segment 22, and so on. The target time point is attribute information of the target multimedia data, so that if the target multimedia data is acquired, the target time point can be determined. For example, the video segment 55 may carry its attribute information, i.e., the target time point 1 minute 25 seconds.

Acquiring skip playing in a media form through a skip time point, and after confirming the skip playing in the media form, taking a target time point of data skipped and played in the media form as a reference to ensure the skip playing in other media forms of the multimedia.

For example, the audio segment 133 of the target multimedia data is obtained according to the slice 13, and the target time point carried by the audio segment 133 is confirmed to be 1 minute and 30 seconds.

In one embodiment, determining a target time point of target multimedia data according to the target multimedia identifier may include: according to a predetermined data transmission protocol, carrying out address expansion on the target multimedia identifier to obtain a target multimedia address; acquiring target multimedia data based on the target multimedia address; and acquiring a target time point of the target multimedia data from the target multimedia data.

The data transmission protocol is a rule which needs to be followed and observed in the data transmission process, the data transmission protocol is selected, and data is set based on the selected data transmission protocol, so that effective transmission of the data can be guaranteed. For example, a Hypertext transfer protocol (HTTP) is a data transfer protocol that specifies a rule for mutual communication between a terminal and an internet server and transfers internet data via the internet. The destination multimedia address may be a network address that may be used directly to request data. According to the predetermined data transmission protocol, the address of the target multimedia identifier is extended to obtain the target multimedia address, the implementation mode of the address extension of the identifier can be changed due to the difference of the predetermined data transmission protocol, and the selection of the predetermined data transmission protocol can be flexibly selected based on the application scene and the actual requirement, which is not limited herein.

The target multimedia data is obtained based on the target multimedia address, which may be a target time point for requesting a specific object (the specific object may be determined according to a predetermined data transmission protocol and the target multimedia address, such as a server, etc.) for the address, receiving the target multimedia data included in the address, and obtaining the target multimedia data from the target multimedia data.

105. And determining candidate multimedia identifications based on the second mapping relation and the target time point.

The candidate multimedia identifier may belong to a second multimedia segment identifier, and the candidate segment identifier may represent multimedia data to be played after the skip, and the second mapping relationship may include one or more than one, for example, if the multimedia media is in the form of audio 1, audio 2, and text 1, and the audio 1 user determines the target data, the second mapping relationship may include an audio 2 mapping relationship and a text 1 mapping relationship.

The candidate multimedia identification is key information for realizing that the skip playing is finished in a media form corresponding to the second multimedia fragment, and the determination of the candidate multimedia identification through the target time point plays a decisive role in eliminating the problems of pause, unsynchronized sound and pictures and the like in the skip playing process.

For example, 5 segment identifiers are included in the audio 2 index file, which are segment 21, segment 22, segment 23, segment 24, and segment 25. Determining candidate multimedia identifications in the audio 2 index file as fragments 22 through an audio 2 mapping relation (the mapping relation between the audio 2 fragment identification and the playing time point is called as an audio 2 mapping relation) and a target time point (1 minute 30 seconds);

the text 1 index file comprises 8 fragment identifications, namely a fragment 31, a fragment 32, a fragment 33, a fragment 34, a fragment 35, a fragment 36, a fragment 37 and a fragment 38. And determining candidate multimedia identifications in the text 1 index file as fragments 35 according to a text 1 mapping relation (the mapping relation between the text 1 fragment identification and the playing time point is called as a text 1 mapping relation) and a target time point (1 minute 30 seconds).

In an embodiment, determining the candidate multimedia identifications based on the second mapping relationship and the target time point may include the steps of: determining a candidate playing time period to which the target time point belongs, and determining a candidate multimedia identifier corresponding to the candidate playing time period based on the second mapping relationship, for example, determining a candidate playing time period X to which the target time point belongs for 1 minute and 30 seconds: and 1 minute 28 seconds to 1 minute 35 seconds, and according to the second mapping relation, determining that the multimedia identifier corresponding to the X is X, wherein the X is the candidate multimedia identifier.

106. And skipping playing is carried out according to the target time point, the target multimedia data and the candidate multimedia data corresponding to the candidate multimedia identifier.

For example, jumping play to audio a may be implemented based on the target data 1 minute 30 seconds, the target multimedia data audio segment 133, the candidate multimedia data 222 corresponding to the candidate multimedia identification segment 22, and the candidate multimedia data 355 corresponding to the candidate multimedia identification segment 35.

In an embodiment, before performing skip playing according to the target time point, the target multimedia data, and the candidate multimedia data corresponding to the candidate multimedia identifier, the method may further include the steps of: according to a predetermined data transmission protocol, address expansion is carried out on the candidate multimedia identification to obtain a candidate multimedia address; candidate multimedia data is obtained based on the candidate multimedia addresses.

Specifically, according to the predetermined data transmission protocol, address expansion is performed on the candidate multimedia identifier to obtain a candidate multimedia address, an implementation manner of address expansion on the identifier may change based on a change of the predetermined data transmission protocol, and selection of the predetermined data transmission protocol may be flexibly selected based on an application scenario and an actual requirement, which is not limited herein. The candidate multimedia data is obtained based on the candidate multimedia address, which may be a request for a specific object (the specific object may be determined according to a predetermined data transmission protocol and a target multimedia address, such as a server, etc.), and the candidate multimedia data contained in the address is received.

In an embodiment, performing skip playing according to the target time point, the target multimedia data, and the candidate multimedia data corresponding to the candidate multimedia identifier may include:

(1) and acquiring a third mapping relation between the candidate data packet of the candidate multimedia data and the candidate playing time point.

For example, for candidate multimedia data in a media form of video, each candidate data packet may include a frame image, and the data packet carries a corresponding playing time point of the frame image, where the playing time point may be a starting playing time point or an ending playing time point of the frame image, and the determination of the playing time point may be flexibly selected in an application process according to an actual situation, and the like.

(2) And determining the data packet based on the third mapping relation and the candidate time point.

In an embodiment, determining the data packet based on the third mapping relationship and the candidate time point may include the steps of: confirming a playing time point matched with the target time point according to the candidate playing time point; and confirming the data packet corresponding to the playing time point matched with the target time point based on the third mapping relation.

(3) And skipping playing is carried out according to the data packet and a target data packet obtained based on the target multimedia data.

In an embodiment, performing skip play according to the data packet and a target data packet obtained based on target multimedia data may include the steps of: analyzing the data packet and a target data packet obtained based on the target multimedia data respectively to obtain data and target data; and skipping playing is carried out according to the data and the target data.

Specifically, the data packet and the target data packet may be playing data required for performing skip playing, the data packet and the target data packet may be two data packet sets (one data packet set and one target data packet set), or multiple data packet sets (one target data packet set and multiple data packet sets), the data packet and the target data packet obtained based on the target multimedia data are respectively parsed, that is, data in the data packet and the target data packet are parsed, for example, the data packet and the target data packet may be decoded based on a decoding manner, or the data packet and the target data packet are decompressed, and the like, so as to obtain data and target data, the skip playing is performed according to the data and the target data, the data and the target data may be processed based on a media form of the data and the target data, for example, if the media form is a video, the corresponding data or the target data may be sent to a device for rendering, to play; if the media is in the form of audio, the corresponding data, target data, or data and target data may be transmitted to a speaker for playback, and so on. It should be noted that the playing time of the data and the target data needs to be the same to ensure normal playing.

In an embodiment, analyzing the data packet and a target data packet obtained based on the target multimedia data to obtain data and target data respectively may include the steps of: the data and the target data are stored into a blockchain.

The blockchain is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism and an encryption algorithm. A block chain (Blockchain), which is essentially a decentralized database, is a series of data blocks associated by using a cryptographic method, and each data block contains information of a batch of network transactions, so as to verify the validity (anti-counterfeiting) of the information and generate a next block. The blockchain may include a blockchain underlying platform, a platform product services layer, and an application services layer.

The block chain underlying platform can comprise processing modules such as user management, basic service, intelligent contract and operation monitoring. The user management module is responsible for identity information management of all blockchain participants, and comprises public and private key generation maintenance (account management), key management, user real identity and blockchain address corresponding relation maintenance (authority management) and the like, and under the authorization condition, the user management module supervises and audits the transaction condition of certain real identities and provides rule configuration (wind control audit) of risk control; the basic service module is deployed on all block chain node equipment and used for verifying the validity of the service request, recording the service request to storage after consensus on the valid request is completed, for a new service request, the basic service firstly performs interface adaptation analysis and authentication processing (interface adaptation), then encrypts service information (consensus management) through a consensus algorithm, transmits the service information to a shared account (network communication) completely and consistently after encryption, and performs recording and storage; the intelligent contract module is responsible for registering and issuing contracts, triggering the contracts and executing the contracts, developers can define contract logics through a certain programming language, issue the contract logics to a block chain (contract registration), call keys or other event triggering and executing according to the logics of contract clauses, complete the contract logics and simultaneously provide the function of upgrading and canceling the contracts; the operation monitoring module is mainly responsible for deployment, configuration modification, contract setting, cloud adaptation in the product release process and visual output of real-time states in product operation, such as: alarm, monitoring network conditions, monitoring node equipment health status, and the like.

The application service layer provides the application service based on the block chain scheme for the business participants to use.

The method described in the above embodiments is further illustrated in detail by way of example.

The embodiment takes the example that the multimedia playing apparatus is specifically integrated in the terminal as an example.

In this embodiment, a video playing method is described in detail by taking an example in which playing is performed based on the HLS protocol and multimedia is a video including two media forms. For example, referring to fig. 3 and 4, fig. 3 shows that the current playing time point of a video M with a video length of 30 seconds is 5 seconds, that is, the content of the video M at 5 th second is played, and the jumping time point of the video M is determined to be 13 seconds; fig. 4 shows that the jump playing is performed based on the determined jump time point of 13 seconds, i.e. the 13 th second content of the video M is played.

As shown in fig. 5, fig. 5 is a schematic flow chart of a video playing method according to the present application. The video playing method can comprise the following steps:

201. the terminal acquires an index file of the video, wherein the index file comprises a first mapping relation between a first multimedia fragment identifier and a playing time period and a second mapping relation between a second multimedia fragment identifier and the playing time period.

For example, the embodiment is based on the HLS protocol, and the index file may include video.m3u8 and radio.m3u 8. Wherein, video.m3u8 can contain fragment identification v0.ts, v1.ts, and v2.ts, specifically, the time length that v0.ts corresponds is 9 seconds, the time length that v1.ts corresponds is 10 seconds, the time length that v2.ts corresponds is 7 seconds, in video.m3u8, confirm the corresponding broadcast time quantum of fragment identification according to the time length that fragment identification and fragment identification correspond, and obtain the first mapping relation of fragment identification and broadcast time quantum: v0.ts for 0 to 8 seconds, v1.ts for 9 to 18 seconds, v1.ts for 19 to 25 seconds.

radio.m3u8 can contain fragment identification r0.ts, r1.ts, and r2.ts, specifically, the time length that r0.ts corresponds is 10 seconds, the time length that r1.ts corresponds is 10 seconds, the time length that r2.ts corresponds is 6 seconds, in video.m3u8, confirm the corresponding broadcast time period of fragment identification according to the time length that fragment identification and fragment identification correspond, and obtain the second mapping relation of fragment identification and broadcast time period: r0.ts for 0 to 9 seconds, r1.ts for 10 to 19 seconds, and r2.ts for 20 to 25 seconds.

The method for the terminal to obtain the video.m3u8 and the radio.m3u8 may be to request the server for addresses based on the video.m3u8 and the radio.m3u8, and obtain the first mapping relationship and the second mapping relationship in the addresses and other information (e.g. information such as # EXTM3U for identifying the index file).

202. And the terminal plays the video according to the index file.

For example, playing a video according to video.m3u8 and radio.m3u8 may obtain video data and audio data corresponding to v0.ts and r0.ts, and place the video data in a player for rendering and playing, and place the audio data in a speaker for playing.

203. And when a jump playing instruction is received, the terminal acquires the jump time point of the video.

For example, when a jump play instruction is received, the terminal acquires a jump time point 13 seconds input by the user.

204. And the terminal determines the target multimedia identifier based on the first mapping relation and the jumping time point.

For example, referring to fig. 6, the terminal determines, according to the playing time period (the jumping time period includes a start time point and an end time point) in the first mapping relationship, that a playing time period in which the start time point is greater than the jumping time point and the end time point is less than the jumping time point is satisfied, that is, 9 seconds to 18 seconds of the playing time period, and then determines, according to the first mapping relationship, a segment identifier v1.ts corresponding to 9 seconds to 18 seconds of the playing time period, that is, a target multimedia identifier is v1. ts.

205. And the terminal determines a target time point of the target multimedia data according to the target multimedia identifier, wherein the target multimedia data corresponds to the target multimedia identifier.

For example, referring to fig. 6, the terminal may perform address expansion on the target multimedia identifier v1.ts based on the HTTP protocol to obtain a target multimedia address, request the target multimedia address from the server to obtain the target multimedia data, and confirm that the play time point carried by the first data packet of the target multimedia data is 9 seconds, where the target time point is 9 seconds.

206. And based on the second mapping relation and the target time point, the terminal determines the candidate multimedia identification.

For example, referring to fig. 6, the terminal determines, according to the playing time period (the jumping time period includes the starting time point and the ending time point) in the second mapping relationship, that is, the playing time period is from 0 second to 9 seconds, and then determines, according to the second mapping relationship, the fragment identifier r0.ts corresponding to the playing time period from 0 second to 9 seconds, that is, the candidate multimedia identifier is r 0.ts.

207. And the terminal determines candidate multimedia data according to the candidate multimedia identification.

For example, the terminal may perform address expansion on the candidate multimedia identifier r0.ts based on the HTTP protocol to obtain a candidate multimedia address, and request the candidate multimedia address from the server to obtain candidate multimedia data.

208. And the terminal acquires a third mapping relation between the candidate data packet of the candidate multimedia data and the candidate playing time point.

For example, the candidate multimedia data is 10 candidate data packets (e.g., packet 1, packet 2, packet 3, packet 4, packet 6, packet 7, packet 8, packet 9, and packet 10), each candidate data packet carries a candidate play-out time point (the candidate play-out time point is a start time point of the data packet), and then a third mapping relationship exists between the candidate data packet and the candidate play-out time point: packet 1 for 0 seconds, packet 2 for 1 second, packet 3 for 2 seconds, packet 4 for 3 seconds, packet 5 for 4 seconds, packet 6 for 5 seconds, packet 7 for 6 seconds, packet 8 for 7 seconds, packet 9 for 8 seconds, and packet 10 for 9 seconds.

209. And the terminal determines the data packet based on the third mapping relation and the candidate time point.

For example, the candidate playing time point in the third mapping relation identical to the candidate time point, i.e. 9 seconds, is confirmed, and then the data packet, i.e. the packet 10, is determined according to the third mapping relation.

210. And the terminal analyzes the data packet and a target data packet obtained based on the target multimedia data to obtain data and target data.

For example, the destination data packet may be the content of the destination multimedia data, the destination multimedia data includes packet a, packet B, packet C, packet D, and packet E, and the destination data packet may be packet a, decoded packet 10, and packet a, which correspond to the data and the destination data.

211. And the terminal skips and plays according to the data and the target data.

For example, the terminal sends data to the speaker and target data to the player at the same time point, so that the effect of skipping to 13 seconds for playing the video can be realized.

As shown in fig. 7, putting the user dragging time point into the video dragging logic to obtain the target time point may correspond to step 203, step 204, and step 205 in the embodiment, then putting the target time point into the audio dragging logic, may correspond to step 205, step 206, step 207, step 208, and step 209 in the embodiment, then performing a decoding operation on the audio data packet and the video data packet to obtain audio data and video data, and corresponds to step 210 in the embodiment, finally putting the audio data into a speaker, putting the video data into a player for rendering, and ensuring that the time points of putting the audio data and the video data are consistent, and corresponding to step 211 in the embodiment, that is, an operation step of jumping play.

In the embodiment of the application, a terminal first obtains an index file of a video, the index file comprises a first mapping relation between a first multimedia fragment identifier and a playing time period and a second mapping relation between a second multimedia fragment identifier and the playing time period, then the terminal plays the video according to the index file, when a skip playing instruction is received, the terminal obtains a skip time point of the video, the terminal determines a target multimedia identifier based on the first mapping relation and the skip time point, the terminal determines a target time point of target multimedia data according to the target multimedia identifier, the target multimedia data corresponds to the target multimedia identifier, the terminal determines a candidate multimedia identifier based on the second mapping relation and the target time point, the terminal determines candidate multimedia data according to the candidate multimedia identifier, the terminal obtains a third mapping relation between a candidate data packet of the candidate multimedia data and the candidate playing time point, the terminal determines a data packet based on the third mapping relation and the candidate time point, analyzes and respectively analyzes the data packet and a target data packet obtained based on the target multimedia data to obtain data and target data, and skips to play according to the data and the target data.
