Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of a method for playing streaming media data according to an embodiment of the present invention, where the method is applicable to a situation where n transport stream files before the streaming media data are directly downloaded for playing, the method may be executed by a playing apparatus of the streaming media data, and the playing apparatus of the streaming media data may be implemented by software and/or hardware, and may be configured in a computer device, for example, a personal computer, a mobile terminal (e.g., a mobile phone, a tablet computer, etc.), a wearable device (e.g., glasses, a watch, etc.), and the method specifically includes the following steps:
The operating system of the computer device may include Android (Android), iOS, Windows, and the like, and applications supporting playing of streaming media data, such as a live application, a browser, a short video application, a shopping application, and the like, may be installed in the operating system.
The form of the streaming media data may be different in different applications, for example, in a live application, a shopping application, the streaming media data may be live video data, in a browser, the streaming media data may be a tv show, a movie, in a short video application, the streaming media data may be short video data, and the like, which is not limited in this embodiment.
Further, the application may be a stand-alone application, or may be an application configuring a component of the player (e.g., an SDK (Software Development Kit)), which is not limited in this embodiment.
A user starts an application, and the application requests a Web (Web page) server for a page, so that the page of the application is loaded in the application, and in the page, corresponding summary information for displaying streaming media data can be displayed, and the summary information is information for summarizing the streaming media data, such as a thumbnail of the streaming media data, a title of the streaming media data, viewing data (e.g., the number of likes, the number of comments, the number of views, etc.) of the streaming media data, and so on.
For example, for a live broadcast application, the summary information of the live video data may be displayed on a page such as a home page, a page below two levels (e.g., a web game, a stand-alone game, a hand game, a leisure game), a live broadcast room, etc., and for a short video application, the summary information of the live video data may be displayed on a page such as a home page, a producer's detailed page, etc., which is not limited in this embodiment.
Since the update frequency of the download address of the streaming media data is high, the streaming media data is generally managed by an independent streaming media server, the streaming media server divides the streaming media data into a plurality of transport stream files, and each transport stream file is configured with a download address, such as a Uniform Resource Locator (URL).
The streaming media server sorts the plurality of transport stream files of the streaming media data according to a time sequence, so that the plurality of transport stream files are played according to the sorting in the following, that is, the earlier the sorting is, the earlier the playing time is, and conversely, the later the sorting is, the later the playing time is.
In this embodiment, the transport stream files with the sorting less than or equal to n (n is a positive integer, such as 1, 2, 3, 4, etc.) are set as the first target transport stream file, that is, the n transport stream files played first are set as the first target transport stream file, for the convenience of distinguishing, the download address configured for the first target transport stream file is denoted as the first address, that is, the streaming media data is configured with the first address, the first address is the download address of the first target transport stream file in the streaming media data, the first address exists in an independent form and is not dependent on the playlist (such as m3u8), that is, the first address is not recorded in the playlist (such as m3u 8).
It should be noted that the number n of the first target transport stream files can be set by those skilled in the art according to the actual situation of the network, the computer equipment and other factors, the number n of first target transport stream files is typically much smaller than the total number of transport stream files, e.g., if the number of the transport stream files is too large and the performance of the computer device is limited, which results in that the time for the computer device to analyze and transmit the download addresses of the plurality of transport stream files is long, at this time, the number n of first target transport stream files may be set to a larger value, such as 2, 3, for example, if the network quality is better and the download address for transmitting the multiple transport stream files is faster, in order to reduce the influence on the streaming media service protocol, at this time, the number n of the first target transport stream files may be set to a larger value, such as 1, etc., which is not limited by the embodiment.
Generally, after loading a page, an application requests a streaming server for a first address corresponding to an identifier of streaming media data according to the identifier of the streaming media data in the page (e.g., an ID of a live broadcast).
Specifically, the application may send a query request to the streaming media server for the streaming media data (represented by the identifier of the streaming media data), and the streaming media server, upon receiving the query request, queries the database for a first address configured for the streaming media data, encapsulates the first address in a query response, and sends the query response to the application.
At this time, the application may receive a query response sent by the streaming server in response to the query request, and extract the first address from the query response.
Of course, the application may obtain the first address of the streaming media data in other manners besides the first address of the streaming media data distributed by the streaming media server, for example, the streaming media server transmits the first address of the streaming media data to the Web server, the Web server packages the first address of the streaming media data into a document (e.g., an HTML (HyperText Markup Language) document) of a corresponding page, and sends the first address of the streaming media data to the application along with the document of the page, and so on, which is not limited in this embodiment.
The user browses the summary information of each streaming media data to obtain the general content of each streaming media data, and for the streaming media data which may be interested, the user can trigger a starting operation aiming at the summary information of the streaming media data to instruct the application to load and play the streaming media data.
The manner in which a user triggers a start operation to act on summary information varies from computer device to computer device.
If the computer device is a device supporting key control operation, such as a personal computer, the user can trigger operations such as clicking and long-time pressing aiming at the summary information by using a key control mode through an external device connected with the computer device, so that the summary information is selected, and the application receives starting operation acting on the summary information. The external device includes, but is not limited to, a mouse, a keyboard, and the like.
For example, as shown in fig. 2, a browser in a personal computer loads a live broadcast room, the live broadcast room includes a first screen area 210 and a non-first screen area 220, information important to live broadcast, such as a navigation bar 201, a live broadcast picture 202, a bulletin board 203, a list 204, an interactive window 205 of the live broadcast room, and the like, can be displayed in the first screen area 210, and information less important to live broadcast, such as a dynamic column 206, a guild column 207, a recommendation column 208, and the like, can be displayed in the non-first screen area 220.
The information in the list 204, the dynamic column 206, and the recommendation column 208 is summary information of live video data (streaming media data), and the user clicks the information in the list 204, the dynamic column 206, and the recommendation column 208 by using a mouse, a keyboard, or the like, and may be regarded as triggering a start operation acting on the summary information.
If the computer device is a device supporting touch operation, such as a mobile terminal, the user may trigger touch operation such as clicking, long-pressing, and the like on the summary information by using a finger or a touch pen in a touch manner, so as to select the summary information, so that the application receives a start operation acting on the summary information.
For example, as shown in fig. 3, a live application of the mobile terminal loads a homepage of a live platform, summary information 301 of a plurality of live rooms, such as thumbnails, head portraits of the anchor, the number of people watching the live rooms, and the like, is displayed in the homepage, and a user clicks the summary information 301 with a finger, which may be regarded as triggering a start operation acting on the summary information.
A player capable of supporting playing of streaming media data, such as a VideoView in an Android system, is configured in the computer device, and the player may be a component independent of an application or a component (such as an SDK) in the application, which is not limited in this embodiment.
When receiving a starting operation acting on the summary information, the application queries a first address configured for the streaming media data to which the summary information belongs, and starts a player, taking a VideoView as an example, the application can add a video _ View, and uses a setplayreview interface to associate the application with a video _ View control which is just added to the interface.
The application transmits the first address to the player, thereby starting the player, which accesses the first address, thereby downloading a first target transport stream file of streaming media data.
And step 104, if the downloading of the first target transport stream file is finished, playing the first target transport stream file.
If the player finishes downloading the first target transport stream file, the player may render the first target transport stream file, thereby playing the first target transport stream file.
In this embodiment, summary information of streaming media data is displayed, a start operation acting on the summary information is received, a first address is accessed in response to the start operation, a first target transport stream file of the streaming media data is downloaded, wherein the first target transport stream file is a transport stream file with a sequence less than or equal to n, if downloading of the first target transport stream file is completed, the first target transport stream file is played, a download address of an initial partial transport stream file in the streaming media data is separated from a playlist, that is, the first address exists in an independent form, does not depend on the playlist, is not recorded in the playlist, after the first address is obtained, the first address can be accessed, the initial partial transport stream file can be downloaded for playing, the consumed time is 1-RTT, the time for downloading the playlist is saved, and therefore, the time required for starting playing the streaming media data is saved, The second-on rate (i.e. the proportion of open motion picture within 1 s) at which the streaming media data is played is increased.
Tests show that the second opening rate of the live video data can be improved by 3% by applying the embodiment to the live on-demand service.
Example two
Fig. 4 is a flowchart of a playing method of streaming media data according to a second embodiment of the present invention, where the present embodiment further adds an operation of parsing a playlist based on the foregoing embodiment, and the method specifically includes the following steps:
The streaming media server sequences the plurality of transport stream files of the streaming media data according to a time sequence, and records the download addresses of the plurality of transport stream files in a playlist (e.g., m3u8) according to the time sequence, that is, the internal information of the playlist (e.g., m3u8) records a series of media fragment resources (i.e., transport stream files), and plays the media fragment resources in sequence, that is, the streaming media data can be completely displayed.
Taking m3u8 as an example, the format of m3u8 is as follows:
#EXTM3U
#EXT-X-TARGETDURATION:10
#EXTINF:9.009,
http://media.example.com/first.ts
#EXTINF:9.009,
http://media.example.com/second.ts
#EXTINF:3.003,
http://media.example.com/third.ts
when m3u8 is used as a Master Playlist (Master Playlist), multiple copies of a Stream list resource (Variant Stream) of the same media resource are provided therein. The format is as follows:
#EXTM3U
#EXT-X-STREAM-INF:BANDWIDTH＝150000,RESOLUTION＝416x234,CODECS＝"avc1.42e00a,mp4a.40.2"
http://example.com/low/index.m3u8
#EXT-X-STREAM-INF:BANDWIDTH＝240000,RESOLUTION＝416x234,CODECS＝"avc1.42e00a,mp4a.40.2"
http://example.com/lo_mid/index.m3u8
#EXT-X-STREAM-INF:BANDWIDTH＝440000,RESOLUTION＝416x234,CODECS＝"avc1.42e00a,mp4a.40.2"
http://example.com/hi_mid/index.m3u8
#EXT-X-STREAM-INF:BANDWIDTH＝640000,RESOLUTION＝640x360,CODECS＝"avc1.42e00a,mp4a.40.2"
http://example.com/high/index.m3u8
#EXT-X-STREAM-INF:BANDWIDTH＝64000,CODECS＝"mp4a.40.5"
http://example.com/audio/index.m3u8
for a streaming media service Protocol, such as HLS, the whole streaming media data is downloaded by dividing it into small HTTP (hypertext Transfer Protocol) based transport stream files ts, and a part of the transport stream files ts is downloaded each time. When streaming media data is being played, the application may choose to download the same transport stream file ts from many different alternate sources at different rates, allowing the streaming media session to accommodate different data rates. When a streaming media session is started, the application will download a playlist (e.g., m3u8) containing metadata for finding an available media stream.
Of course, besides the download addresses of the plurality of transport stream files, the playlist (e.g., m3u8) may be accompanied by other description information, such as bandwidth information, for providing to the application.
For video-on-demand, such as television drama, movie, short video, etc., the application downloads the transport stream file ts in sequence and plays the files in sequence. For live broadcasting, the application periodically re-requests the playlist (e.g., m3u8), queries a new transport stream file ts, and downloads the new transport stream file ts for playing.
In this embodiment, the streaming media data may be configured with a first address and a second address, where the first address is a download address of a first target transport stream file in the streaming media data, and the second address is a download address of a playlist (e.g., m3u8) in the streaming media data.
Generally, after loading a page, an application requests a streaming media server for a first address and a second address corresponding to an identifier of streaming media data according to the identifier of the streaming media data in the page (e.g., an ID of a live broadcast).
Specifically, the application may send a query request to the streaming media server for the streaming media data (represented by an identifier of the streaming media data), and when receiving the query request, the streaming media server queries the database for a first address and a second address configured for the streaming media data, encapsulates the first address and the second address into a query response, and sends the query response to the application.
At this time, the application may receive a query response sent by the streaming media server in response to the query request, and extract the first address and the second address from the query response.
Since the streaming media service protocol such as HLS is to agree on the download address (i.e. the second address) of the playlist (e.g. m3u8) in the transport stream media data, while the present embodiment transmits the download address (i.e. the second address) of the transport stream file with the rank less than or equal to n in addition to the download address (i.e. the second address) of the playlist (e.g. m3u8), in order to distinguish the first address from the second address, the streaming media server may agree to mark the first tag for the first address and mark the second tag for the second address in the query response.
Therefore, when the query response is analyzed, the first tag and the second tag can be respectively identified in the query response according to convention, on one hand, the character string marking the first tag is searched in the query response to obtain the first address, and on the other hand, the character string marking the second tag is searched in the query response to obtain the second address.
Of course, in addition to distributing the first address and the second address of the streaming media data through the streaming media server, the application may also obtain the first address and the second address of the streaming media data in other manners, for example, the streaming media server transmits the first address and the second address of the streaming media data to the Web server, the Web server packages the first address and the second address of the streaming media data into a document (such as an HTML document) of a corresponding page, and sends the first address and the second address of the streaming media data to the application along with the document of the page, and so on, which is not limited in this embodiment.
Step 403, in response to the start operation, accessing the first address to download the first target transport stream file of streaming media data.
The first target transmission stream file is a transmission stream file with the sequence less than or equal to n.
In this embodiment, the Application may transmit the first address to the player and may transmit the second address to the player, so as to distinguish the first address from the second address, when an Application Programming Interface (API) of the Application calling player generates a call request, it may be agreed to mark a third tag for the first address and a fourth tag for the second address in the call request.
Therefore, when the player analyzes the call request, the third tag and the fourth tag can be respectively identified from the call request according to convention, on one hand, the character string marking the third tag is searched in the call request to obtain the first address, and on the other hand, the character string marking the fourth tag is searched in the call request to obtain the second address.
In this embodiment, the player accessing the first address and downloading the first target transport stream file of the streaming media data and the player accessing the second address and downloading the playlist (e.g., m3u8) of the streaming media data belong to a serial operation.
Further, the player first accesses the first address, downloads the first target transport stream file of the streaming media data, and when the first target transport stream file of the streaming media data is completed, then accesses the second address, downloads the playlist (e.g., m3u8) of the streaming media data, avoids the playlist (e.g., m3u8) of the streaming media data from preempting resources (e.g., bandwidth, processor resources, memory resources, etc.) of the computer device, allocates the resources (particularly, bandwidth) of the computer device to the first target transport stream file of the streaming media data as much as possible, increases the speed of downloading the first target transport stream file of the streaming media data, reduces the time consumption of downloading the first target transport stream file of the streaming media data, and thus increases the efficiency of starting the streaming media data.
In addition, after the first target transport stream file of the downloaded streaming media data is completed, the first target transport stream file is not sensitive to bandwidth resources, at this time, the first target transport stream file of the streaming media data played by the player and the playlist (e.g., m3u8) of the player access address and the downloaded streaming media data belong to parallel operations, and the influence of the playlist (e.g., m3u8) of the downloaded streaming media data on the resource of the computer device is small and can be ignored.
A plurality of download addresses of the transport stream file are recorded in the playlist (e.g., m3u8), and the download address of the transport stream file is denoted as a third address for the sake of distinction.
The player traverses each transport stream file in the playlist (e.g., m3u8), and screens out a transport stream file which belongs to the same streaming media file as the first target transport stream file and has a rank greater than n, as a second target transport stream file, that is, the second target transport stream file is a transport stream file having a rank greater than n.
The player accesses a third address corresponding to the second target transport stream file, thereby downloading the second target transport stream file of the streaming media data.
Generally, the time length of one transport stream file ts varies from several seconds to several minutes, and within several seconds, the player may complete downloading a playlist (e.g., m3u8) of streaming media data, parse the playlist, and download a second target transport stream file in the streaming media data, so as to reduce modifications to the streaming media service protocol as much as possible, and maintain the universality of the streaming media service protocol, where n is preferably 1, that is, the client accesses the first address to download the first transport stream file of the streaming media data, and if downloading the first transport stream file is complete, plays the first transport stream file, and accesses the second address to download the playlist of the streaming media data, accesses the third address in the playlist, and downloads the second and subsequent transport stream files in the streaming media data.
In one embodiment of the present invention, the step 406 may include the steps of:
step 4061, query fourth address.
Step 4062 compares the fourth address to the third address.
In order to maintain the generality of the streaming media protocol, the playlist (e.g., m3u8) of the streaming media data may complete recording all the transport stream files ts in the streaming media data, i.e., the playlist (e.g., m3u8) of the streaming media data has the first target transport stream file and the second target transport stream file simultaneously.
Thus, the player screens out the first target transport stream file to distinguish the second target transport stream file while traversing the individual transport stream files in the playlist (e.g., m3u 8).
Specifically, the player may query the current fourth address, which is the download address of the transport stream file that has completed downloading, and compare the fourth address with the third addresses in the playlist (e.g., m3u 8).
It should be noted that, due to the existence of factors such as the aging of the cache, the user switching to other streaming media files, and the like, the fourth address may include a download address of the transport stream file ts in the current streaming media data, or may include a download address of the transport stream file ts in other streaming media data, and the fourth address may be the same as the first address, or may be different from the second address, which is not limited in this embodiment.
Step 4063, if the fourth address is the same as part of the third address, accessing part of the third address different from the fourth address in sequence to download a second target transport stream file in the streaming media data.
And aiming at the comparison result of the fourth address and the third address, if the fourth address is the same as part of the third address, the same part is the download address of the transport stream file ts in the same stream media data, namely the first address, at the moment, the player can sequentially access other third addresses after the first address, and the addresses are different from the fourth address, so that the download address of the second target transport stream file is represented, and the second target transport stream file in the stream media data is downloaded.
In an embodiment of the present invention, the player may be provided with some mechanisms, for example, if the transport stream file is downloaded again due to a failure to play the transport stream file, the transport stream file may be downloaded again by traversing the playlist (e.g., m3u8), and in order to avoid that the mechanism repeatedly downloads the transport stream file by traversing the playlist (e.g., m3u8) to cause repeated downloading of the first target file, which may cause repeated playing of the same content by the streaming media data, a part of the third address that is the same as the fourth address may be deleted in the playlist (e.g., m3u8), that is, the first address may be deleted in the playlist (e.g., m3u8), so as to ensure the content of the streaming media.
In addition, the streaming media server may also delete the first address directly from the playlist (e.g., m3u8), and after the player downloads the playlist (e.g., m3u8), the player sequentially accesses the third address in the playlist (e.g., m3u8) in order to download the second target transport stream file in the streaming media data, which is not limited in this embodiment.
During the period of playing the first target transport stream file, the downloading of the second target transport stream file can be usually completed, and when the playing of the first target transport stream file is completed, the playing of the second target transport stream file can be continued in sequence, so that the content of the streaming media data is consistent, and the streaming media data is accurately played.
Further, the player generates a buffer queue, the player reads the transport stream file ts from the buffer queue for playing in a FIFO (First Input First Output, First in First out) manner, the player writes the First target transport stream file into the buffer queue in sequence when downloading the First target transport stream file is completed, and the player writes the second target transport stream file into the buffer queue in sequence when downloading the second target transport stream file is completed.
As for the result of comparing the fourth address with the third address, if the fourth address is different from all the third addresses, it indicates that the fourth address does not have the first address of the current streaming media data, and situations such as a failure of downloading the first target transport stream file, a user jumping to other streaming media data, etc. may occur, at this time, the player accesses the third addresses according to the sequence arranged in the play list (e.g., m3u8), and uses the transport stream file of the following streaming media data as the third target transport stream file, and when downloading of at least one third target transport stream file is completed, the player pauses playing the first target transport stream file, and plays the third target transport stream file, thereby ensuring accurate playing of the streaming media data.
It should be noted that, for simplicity of description, the method embodiments are described as a series of acts or combination of acts, but those skilled in the art will recognize that the present invention is not limited by the illustrated order of acts, as some steps may occur in other orders or concurrently in accordance with the embodiments of the present invention.
