Background

As the application scenarios of the streaming media technology become more diverse, the user experience of the streaming media service also gets attention. In the related art, the transmission of streaming media data may be implemented by a streaming media service protocol, for example: DASH (Dynamic Adaptive Streaming over HTTP), HLS (HTTP Live Streaming), and the like. When the streaming media data is transmitted through the streaming media service protocol, the streaming media data with a larger size can be divided to obtain a plurality of slices, and then the media description file is generated according to the slice information of the plurality of slices. Therefore, the slice information of the slice to be requested can be accurately acquired according to the media description file, and then the corresponding slice is acquired according to the slice information and played. However, when the streaming media data is divided into a large number of slices, the size of the media description file generated according to the plurality of slices is large, which results in a long time required for transmitting the media description file, and a long time for the terminal to parse the media description file, which results in a long time required for starting playing the streaming media data, thereby affecting the user experience.

Before explaining the embodiments of the present application in detail, an application scenario related to the embodiments of the present application will be described.

Currently, the application scenarios of the streaming media technology are more diverse, and the transmission of streaming media data can be realized through a streaming media service protocol. When streaming media data, the streaming media data with a large size can be divided to obtain a plurality of slices, and then a media description file is generated according to slice information of the plurality of slices. After the terminal acquires the media description file, the terminal can analyze the media description file, further acquire each slice in the streaming media data according to the information acquired by analysis, and play the acquired slices in real time. The method for playing the streaming media data provided by the embodiment of the application can be used in the above scenario, so that the terminal plays the streaming media data according to the media description file, thereby reducing the time required for starting playing the streaming media data and improving the use experience of the user.

Next, a system architecture related to a method for playing streaming media data provided by an embodiment of the present application is described.

Fig. 1 is a system architecture diagram according to a method for playing streaming media data provided in an embodiment of the present application. As shown in fig. 1, the system 100 includes a terminal 101 and a server 102, and the terminal 101 and the server 102 can be connected in a wireless or wired manner for communication.

The terminal 101 may send a media description file acquisition request to the server 102, where the media description file acquisition request carries a storage path of the media description file, and receives the media description file returned by the server 102. The terminal 101 may generate a slice link of a slice to be acquired according to slice information of a first slice and slice information of a last slice of the streaming media data included in the media description file, and further send a slice acquisition request to the server 102, where the slice acquisition request carries the slice link. After that, the terminal 101 may receive the slice to be acquired returned by the server 102 according to the slice acquisition request, and play the slice to be acquired.

The server 102 may divide the streaming media data into a plurality of slices, generate an original media description file according to slice information of the plurality of slices, and then optimize the original media description file to obtain a media description file. After receiving the media description file acquisition request sent by the terminal 101, the server 102 may acquire the media description file according to a storage path of the media description file carried in the media description file acquisition request, and send the media description file to the terminal 101. Then, the server 102 may receive a slice acquisition request sent by the terminal 101, acquire a slice to be acquired according to a slice link carried in the slice acquisition request, and send the slice to be acquired to the terminal 101, so that the terminal 101 plays the slice to be acquired.

In this embodiment of the application, the terminal 101 may be a device such as a television, a computer, and a smart phone, and fig. 1 is only an example of a television and does not limit the embodiment of the application. The server 102 may be a server or a cluster of servers.

Next, a method for playing streaming media data provided by an embodiment of the present application is described.

Fig. 2 is a flowchart of a method for playing streaming media data according to an embodiment of the present application, where the method may be applied to a terminal, which may be the terminal 101 in fig. 1. As shown in fig. 2, the method comprises the steps of:

step 201: and acquiring the media description file.

Wherein the media description file includes slice information of a first slice and slice information of a last slice of the streaming media data.

The terminal can obtain the storage path of the media description file, and further obtain the media description file according to the storage path of the media description file.

In some embodiments, when the terminal detects a play operation for streaming media data, it may send a storage path acquisition request to the server, and receive a first storage path returned by the server, where the storage path acquisition request carries an identifier of the streaming media data to be played. Then, the terminal may send a media description file acquisition request to the server, where the media description file acquisition request carries the first storage path. After receiving the media description file acquisition request, the server may acquire the media description file according to the first storage path and send the media description file to the terminal. In this way, the terminal can receive the media description file sent by the server.

In this case, since the terminal acquires the first storage path from the server when acquiring the media description file, when the server stores the optimized original media description file to obtain the media description file, the first storage path received by the terminal is the storage path of the media description file.

In other embodiments, the terminal stores a correspondence between the identifier of the streaming media data and the storage path of the media description file, so that the first storage path may be obtained from the correspondence according to the identifier of the streaming media data to be played. After the terminal acquires the first storage path, it may determine whether the first storage path includes the target identifier. If the first storage path includes the target identifier, the media description file may be obtained according to the first storage path. If the first storage path does not include the target identifier, a second storage path may be generated according to the first storage path and the target identifier, and the media description file may be acquired according to the second storage path. The implementation method for obtaining the media description file according to the storage path may refer to the implementation method in the foregoing embodiment, and is not described again.

It is to be noted that, in this case, when the terminal stores the correspondence between the identifier of the streaming media data and the storage path of the media description file, the server may not optimize the original media description file, and thus, the storage path included in the correspondence may be the storage path of the original media description file. And then, the server optimizes the original media description file to obtain the media description file, adds a target identifier in a storage path of the original media description file, and stores the media description file under the path. Therefore, the first storage path acquired by the terminal from the corresponding relationship may be a storage path of the original media description file, that is, the first storage path does not include the target identifier, but the optimized media description file is stored in the server, so that the terminal may determine whether the first storage path includes the target identifier after acquiring the first storage path, and when the first storage path does not include the target identifier, add the target identifier to the first storage path to obtain the second storage path, and further acquire the media description file according to the second storage path.

It should be noted that, target identifiers are stored in both the server and the terminal, and the target identifiers are used to indicate that the storage path is the storage path of the optimized media description file. Optionally, the target identifier may also correspond to a target position, so that the target identifier may be added to the target position of the first storage path, thereby obtaining a second storage path.

Illustratively, the target identification may be "s" and the target location is the end of the storage path. Assuming that the terminal determines that the first storage path is http://10.18.89.77: 8000/outfile. mpd ", it may be determined that the first storage path does not include the target identifier" s ", so that the terminal may add the target identifier" s "at the end of the first storage path to obtain a second storage path" http://10.18.89.77: 8000/outfile. mpd ", and then the terminal may obtain the media description file according to the second storage path.

Optionally, when the server does not store the media description file, the terminal cannot acquire the media description file according to the second storage path, and at this time, the terminal may acquire the original media description file according to the first storage path, that is, the storage path of the original media description file that does not include the target identifier, and further acquire the slice to be played according to the slice information of each slice corresponding to the streaming media data included in the original media description file, and play the acquired slice.

In this embodiment of the present application, before sending the media description file to the terminal, the server may segment the streaming media data to obtain a plurality of slices, generate an original media description file according to slice information of the plurality of slices, and store the original streaming media file, where the original media description file includes slice information of all slices of the streaming media data. Then, the server may obtain an original media description file of the streaming media data, and generate a media description file according to the original media description file. Then, a storage path and an original file name of the original media description file can be obtained, a file name of the media description file is generated according to the original file name and the target identifier, a storage path of the media description file is generated according to the file name of the media description file and the storage path of the original media description file, and the media description file is stored according to the storage path of the media description file.

As an example, after the server obtains the original media description file, the server may delete the slice information of other slices of the streaming media data in the original media description file except the first slice and the last slice, so as to obtain the media description file, and thus, the media description file only includes the slice information of the first slice and the slice information of the last slice of the streaming media data. Then, the server may obtain a storage path and an original file name of the original media description file, add a target identifier to the original file name to obtain a file name of the media description file, replace the original file name included in the storage path of the original media description file with the file name of the media description file, generate a storage path of the media description file, and further store the media description file under the storage path.

Alternatively, the server may directly add the target identifier to the storage path of the original media description file, generate the storage path of the media description file, and store the media description file in the storage path.

Step 202: and acquiring the slice of the streaming media data according to the slice information of the first slice and the slice information of the last slice.

In this embodiment of the application, the terminal may generate slice information of a slice to be acquired according to slice information of a first slice and slice information of a last slice. Then, the slice to be acquired may be acquired according to the slice information of the slice to be acquired.

Wherein the slice information includes a slice link, and the slice link includes a slice number. In this case, the terminal may obtain the slice number of the slice to be acquired, and if it is determined that the slice number of the slice to be acquired is valid according to the slice number included in the slice information of the first slice and the slice number included in the slice information of the last slice, modify the slice number in the slice link included in the slice information of the first slice to the slice number of the slice to be acquired to obtain the slice information of the slice to be acquired, or modify the slice number in the slice link included in the slice information of the last slice to the slice number of the slice to be acquired to obtain the slice information of the slice to be acquired.

Alternatively, the slice information of the slice to be acquired may include a slice link of the slice to be acquired, and the slice link includes a slice number therein.

When the terminal does not detect the selection operation of the user for the playing progress of the streaming media data, the slice number of the slice to be acquired may be acquired by increasing the slice number by 1 starting with the slice number of the first slice, and the slice to be acquired at this time is the second slice. After the second slice is acquired, the slice number of the second slice may be increased by 1 or the slice number of the first slice may be increased to obtain the slice number of the third slice, and so on. When the terminal detects a selection operation of a user for the playing progress of the streaming media data, the slice number of the slice to be acquired can be determined according to the playing time corresponding to the selection operation and the slice number of the first slice, wherein the playing time duration corresponding to one slice is the same.

Illustratively, assuming that the slice number of the first slice is 1, and the playing time duration corresponding to one slice is 5 minutes, the playing time duration corresponding to the detection of the selection operation by the terminal is 26 minutes. In this way, the slice number of the slice to be acquired can be determined to be 6.

After the terminal obtains the slice number of the slice to be obtained, the number of the slices corresponding to the streaming media data can be determined according to the slice number of the first slice and the slice number of the last slice. Thereafter, the slice number of the slice to be acquired may be compared with the slice number of the first slice and the slice number of the last slice. When the slice number of the slice to be acquired is greater than the slice number of the first slice and less than the slice number of the last slice, it may be determined that the slice to be acquired is the slice corresponding to the streaming media data, that is, the slice number of the slice to be acquired is valid.

Illustratively, continuing the foregoing example, assume that the last slice has a slice number of 32. In this way, it can be determined that the slice number 6 of the slice to be acquired is greater than the slice number 1 of the first slice and less than the slice number 32 of the last slice, and it can be determined that the slice to be acquired is the slice corresponding to the streaming media data, that is, the slice number 6 of the slice to be acquired is valid.

After the terminal determines that the slice number of the slice to be acquired is valid, the terminal can acquire the slice link included in the slice information of the first slice, and modify the slice number included in the slice link into the slice number of the slice to be acquired, so that the slice information of the slice to be acquired is obtained. Optionally, the terminal may further obtain a slice link included in the slice information of the last slice, and modify a slice number included in the slice link to a slice number of the slice to be obtained, so as to obtain the slice information of the slice to be obtained.

It should be noted that, the slice link corresponds to a link template, and the link template includes a slice number. Based on this, when the slice links of the multiple slices corresponding to the streaming media data are generated according to the link template, only the slice numbers in the slice links of the multiple slices may be different, and therefore, the slice information of the slice to be acquired may be obtained by modifying the slice number included in the slice link of the first slice or the slice link of the last slice to the slice number of the slice to be acquired.

After acquiring the slice information of the slice to be acquired, referring to fig. 3, the terminal may acquire the slice to be acquired according to the slice information of the slice to be acquired through steps 2021 to 2025 described below.

2021: the terminal may send a slice acquisition request to the server according to a slice link included in slice information of a slice to be acquired.

In the embodiment of the application, the terminal may acquire a slice link included in slice information of a slice to be acquired, and generate a slice acquisition request according to the slice link of the slice to be acquired, where the slice acquisition request carries the slice link for acquiring the slice. Thereafter, the terminal may transmit a slice acquisition request to the server.

2022: and the server receives a slice acquisition request sent by the terminal.

The slice acquisition request carries a slice link of a slice to be acquired, and the slice link of the slice to be acquired is generated by the terminal according to slice information of a first slice and/or slice information of a last slice.

The server can receive a slice acquisition request sent by the terminal and acquire a slice link of a slice to be acquired, wherein the slice link is carried in the slice acquisition request.

2023: and the server acquires the slices to be acquired according to the slice links of the slices to be acquired.

In this embodiment of the application, after the server acquires the slice link of the slice to be acquired, the slice to be acquired indicated by the slice link may be acquired from the plurality of stored slices according to the slice link of the slice to be acquired.

2024: and the server sends the slice to be acquired to the terminal so that the terminal plays the slice to be acquired.

In the embodiment of the application, after the server acquires the slice to be acquired according to the slice acquisition request, the slice to be acquired can be sent to the terminal, so that the terminal plays the slice to be acquired.

2025: and the terminal receives the to-be-acquired slice returned by the server according to the slice acquisition request.

In the embodiment of the application, the terminal may receive the slice to be acquired, which is returned by the server according to the slice acquisition request.

Step 203: and playing the acquired slice.

After receiving the slice returned by the server according to the slice acquisition request, the terminal can play the received slice.

It should be noted that, in this embodiment of the application, the terminal may generate slice information of each slice to be acquired, that is, generate a slice acquisition request according to the slice information of the slice to be acquired, so as to request a server for a slice, and further play the slice. That is, in the embodiment of the present application, the terminal may dynamically generate the slice information of the slice to be acquired according to the media description file, generate the slice information of the slice to be acquired immediately before playing the slice, and further acquire the slice according to the slice information of the slice to be acquired and play the slice. Therefore, the slice information of the slice to be acquired can be prevented from being searched from the media description file, and the time for searching the slice information of the slice to be acquired from the media description file is far longer than the time for generating the slice information of the slice to be acquired, so that the time for acquiring the slice by the terminal can be reduced, and the use experience of a user is improved. In addition, the playing is started while the slices are acquired by the method, and the terminal does not need to acquire all the slices in advance at one time and then starts playing, so that the playing starting time is shortened.

In this embodiment of the application, the media description file only includes slice information of a first slice and slice information of a last slice of the streaming media data, and further may generate slice information of a slice to be acquired according to the slice information of the first slice and the slice information of the last slice. Then, the slice of the streaming media data may be acquired according to the slice information of the slice to be acquired, and the slice may be played. It follows that the size of the media description file is small, thus reducing the time required to transmit the media description file. And the time for the terminal to analyze the media description file is shorter, so that the time for starting playing the streaming media data is reduced, and the use experience of the user is improved.

Referring to fig. 4, an embodiment of the present application provides an apparatus 400 for playing streaming media data, where the apparatus for playing streaming media data may be applied in a client, and the apparatus 400 includes:

a first obtaining module 401, configured to obtain a media description file, where the media description file includes slice information of a first slice and slice information of a last slice of streaming media data;

Optionally, the second obtaining module 402 further includes:

the generating submodule is used for generating the slice information of the slice to be acquired according to the slice information of the first slice and the slice information of the last slice;

and the acquisition submodule is used for acquiring the slice to be acquired according to the slice information of the slice to be acquired.

Optionally, the slice information includes a slice link, the slice link including a slice number;

the generation submodule is specifically configured to:

acquiring a slice number of a slice to be acquired;

and if the slice number of the slice to be acquired is determined to be valid according to the slice number included by the slice information of the first slice and the slice number included by the slice information of the last slice, modifying the slice number in the slice link included by the slice information of the first slice into the slice number of the slice to be acquired to obtain the slice information of the slice to be acquired, or modifying the slice number in the slice link included by the slice information of the last slice into the slice number of the slice to be acquired to obtain the slice information of the slice to be acquired.

Optionally, the obtaining sub-module is specifically configured to:

sending a slice acquisition request to a server according to a slice link included in slice information of a slice to be acquired;

and receiving the to-be-acquired slice returned by the server according to the slice acquisition request.

In summary, in the embodiment of the present application, the media description file only includes slice information of a first slice and slice information of a last slice of the streaming media data, and then slice information of a slice to be acquired may be generated according to the slice information of the first slice and the slice information of the last slice. Then, the slice of the streaming media data may be acquired according to the slice information of the slice to be acquired, and the slice may be played. It follows that the size of the media description file is small, thus reducing the time required to transmit the media description file. And the time for the terminal to analyze the media description file is shorter, so that the time for starting playing the streaming media data is reduced, and the use experience of the user is improved.

Referring to fig. 5, an embodiment of the present application provides a server 500, where the server 500 includes:

a first sending module 501, configured to send a media description file to a terminal, where the media description file includes slice information of a first slice and slice information of a last slice of streaming media data;

an obtaining module 503, configured to obtain a slice to be obtained according to the slice link of the slice to be obtained;

and storing the media description file according to the storage path of the media description file.

In summary, in the embodiment of the present application, the server may simplify the original media description file to obtain the media description file, and store the media description file. Wherein the media description file only includes slice information of a first slice and slice information of a last slice of the streaming media data. After that, the server can send the media description file to the terminal, and the time required for transmitting the media description file can be reduced due to the small size of the media description file. And after the terminal receives the media description file, the time for analyzing the media description file is shorter, the time for starting playing the streaming media data is reduced, and therefore the use experience of a user is improved.
