However, in a related art, recommended resources for a streaming media are all predetermined and are not changed after being determined, and when different users play the streaming media, the recommended resources that are determined before are all displayed in the playing process, that is, the different users all see the same recommended resources when playing the streaming media. However, due to the diversity of users, the same recommended resources are difficult to meet the viewing requirements of different users, and even bring user dislike.
Therefore, the embodiment of the application provides a streaming media determining scheme, which does not determine recommended resources for streaming media in advance, but when a play request of a user for a target streaming media is obtained, by determining preferences of the user, selects target recommended resources which meet the preferences from the recommended resources, determines an index file according to the target streaming media and the obtained target recommended resources, and returns the index file to the terminal. The terminal can download the spliced target streaming media and the target recommendation resources according to the index file, so that the target recommendation resources which accord with the preference of the terminal can be seen when the downloaded content is played, the display efficiency of the recommendation resources is improved, and the streaming media playing experience of the user is improved.
The scheme provided by the embodiment of the application can be applied to streaming media processing equipment, and the streaming media processing equipment has the functions of splicing streaming media and recommending resources and generating the corresponding index file according to the splicing result. The streaming media processing device may specifically be a terminal and/or a server. The terminal device may be a smart phone, a computer, a Personal Digital Assistant (PDA), a tablet computer, or the like; the server may specifically be an independent server, or may also be a cluster server.
In a possible application scenario shown in fig. 1, the streaming media processing device is a server 100, and the server 100 obtains a play request initiated by a user from a terminal 200, where the play request is used to request to play a target streaming media 300, in this application embodiment, the play request carries personalized information of the user, and the personalized information may embody specific preferences of the user, so if a target recommended resource 400 is determined from recommended resources according to the personalized information, the possibility that the target recommended resource 400 meeting the personalized information meets the viewing requirement of the user is high. This corresponds to a service where the user is personalized to the recommended resources.
The server 100 may determine an index file according to the target streaming media 300 and the target recommendation resource 400, where the index file identifies the spliced target streaming media and the target recommendation resource 500. The server 100 returns the index file to the terminal 200, and the terminal 200 can download the spliced target streaming media and the target recommendation resource 500 according to the index file and display the target recommendation resource 400 in the process of playing the downloaded content, so that the target recommendation resource 400 conforming to the user personalized information is more likely to meet the user requirement, and the display efficiency of the recommendation resource and the streaming media experience of the user are improved.
For convenience of description, in the following embodiments of the present application, a server is mainly used as a streaming media processing device to describe the technical solution of the present application.
Fig. 2 is a flowchart of a method of processing streaming media according to an embodiment of the present application, where the method includes:
s201: and acquiring a playing request of the terminal for the target streaming media.
In the embodiment of the present application, the streaming media may be fixed-content media content, such as a tv show, a movie, a short video, and the like, and the streaming media may also be non-fixed-content media content, such as live-type media content. The target streaming media can be any streaming media that the user wants to play.
And including personalized information of a user who initiates the play request in the play request. The personalized information can reflect the user's preference, and the user's preference can reflect what contents the user has more interested in recently or in a period of time, thereby reflecting what the user's attention points are, such as liking for gourmet food, pursuing fashion, getting sports, and the like.
The personalized information may also identify content that the user has suddenly been interested in the near future, e.g., a user who originally enjoys sports suddenly is interested in cooking, and this new taste of the user may be identified by the personalized information.
The application does not limit how to determine the personalized information of the user, and in a possible implementation manner, the personalized information may be determined according to streaming media history downloading and playing information of the user and/or a preference tag of the user.
The historical downloading and playing information of the streaming media reflects the personalized information of the user related to the streaming media, so that the type of the streaming media which the user likes can be determined, and the user preference is determined according to the type of the streaming media.
The preference label of the user can be set by the user or determined according to historical big data analysis of the user. This part of the information may also reflect the user's own preferences.
S202: and acquiring the target recommended resources which accord with the personalized information.
In the embodiment of the application, the recommended resources carry various information to be pushed to the user, and the display form of the recommended resources can be videos, moving pictures, pictures and the like. One possible type of recommended resource may be an advertisement, but also news, current affairs hotspots, etc.
Because the personalized information of the user can embody the specific preference of the user, the possibility that the target recommendation resource which accords with the personalized information meets the viewing requirement of the user is high.
It should be noted that the determined number of the target recommended resources may include at least one, and the specific number may be determined according to the length of the target streaming media, or may be determined according to the number of the target recommended resources actually determined.
In the embodiment of the application, the streaming media processing device can determine the target recommended resource from the recommended resources according to the personalized information. Or other equipment can determine the target recommended resource from the recommended resources according to the personalized information and then return the target recommended resource to the streaming media processing equipment so as to reduce the processing pressure of the streaming media processing equipment.
Therefore, in a possible implementation manner, a recommended resource server is provided, which may store and manage the recommended resources to be recommended in a centralized manner, and the recommended resources may be provided with corresponding classification tags according to the content, the type, and the like of the recommended resources, and after the streaming media processing device obtains the play request through S201, the streaming media processing device may send personalized information carried in the play request to the recommended resource server.
The recommended resource server can determine the target recommended resource of which the classification label accords with the personalized information by matching the personalized information with the classification label of the recommended resource managed by the recommended resource server. The target recommended resource may then be returned to the streaming media processing device.
S203: and determining an index file according to the target streaming media and the target recommended resources.
After determining the target streaming media and the target recommended resources, the streaming media processing device may determine corresponding index files for identifying the spliced target streaming media and the spliced target recommended resources.
The embodiment of the application does not limit the order of determining the index file and splicing the target streaming media and the target recommendation resource, the index file may be determined first, then the target streaming media and the target recommendation resource may be spliced, or the target streaming media and the target recommendation resource may be spliced first, then the index file may be determined, or both may be performed simultaneously.
The method for determining the index file is not limited in this application, and may specifically be related according to the format and type of the streaming media, for example, for streaming media in MP4 and FLV formats, there is a corresponding method for determining the index file.
Since the determined index file is used for the terminal to download the spliced target streaming media and the target recommended resources, the streaming media processing device needs to complete the splicing of the target streaming media and the target recommended resources before returning the index file to the terminal.
In a possible implementation manner, a splicing result may be obtained by splicing the target streaming media and the target recommended resource according to a resource type of the target recommended resource and a splicing position of the target recommended resource in the target streaming media.
S204: and returning the index file to the terminal.
The index file can identify the spliced target streaming media and the spliced target recommended resources, so that the terminal can download the spliced result according to the index file and display the target recommended resources in the playing process, the target recommended resources which meet the personalized information of the user can meet the requirements of the user more possibly, the display efficiency of the recommended resources is improved, and the streaming media experience of the user is improved.
In one possible implementation, before determining the index file, the streaming media processing device needs to specify a splicing position of the target recommended resource, which may be determined based on a splicing rule, such as splicing at the beginning, end, middle, and the like of the streaming media. Or may be determined based on the target recommended resource, e.g., a particular recommended resource may require splicing to a particular location of the streaming media, etc.
For S203, the embodiment of the present application provides an alternative way of determining an index file:
s2031: and determining the resource type of the target recommended resource and the splicing position of the target recommended resource in the target streaming media.
The resource type of the target recommended resource is used for embodying the characteristics of the target recommended resource related to splicing, and taking the target recommended resource as an advertisement as an example, the resource type can include an implantation type and an interpolation type.
The embedded type advertisement can be an advertisement embedded in a certain part of a video picture played in normal streaming media and needing to be shown.
The inserted advertisement can be a complete advertisement inserted during normal streaming media playing, for example, at the position of the head of a film, the end of a film, or a long-time advertisement inserted in the middle of a feature, or a long-time feature content replaced by an advertisement, etc.
The splicing position is used for embodying a specific splicing position of the target recommended resource in the target streaming media.
Optionally, in an application scenario in which a target streaming media may be split into multiple Transport Stream (TS) files and downloaded by a terminal one by one when the terminal plays, the splicing position includes splicing between the transport stream files of the target streaming media or splicing into the transport stream files.
In the embodiment of the present application, the transport stream file may be a file with a short playing length, which is cut out from the streaming media in sequence based on the HLS protocol, and the playing length is typically within 15 seconds, and the encapsulation format is. The terminal may download the transport stream file according to the order indicated in the index file to play the streaming media.
The splicing location of a target recommended resource can identify the transport stream files of the target streaming media to which the target recommended resource is spliced as a complete transport stream file, or into which transport stream file the target recommended resource is spliced, and the specific display location.
S2032: and generating the index file according to the resource type, the splicing position and the streaming media information of the target streaming media.
The streaming media information may identify related information of the target streaming media, such as a playing length, a number of transport stream files, a downloading location, and the like. In combination with the resource type and the splicing position of the target recommended resource determined in S2031, an index file may be generated from sufficient information, so that the index file realizes the function of identifying the spliced target streaming media and the target recommended resource.
When the target recommended resource is spliced in the target streaming media, the encoding parameter of the target recommended resource may not be consistent with the encoding parameter of the adjacent transport stream file in the target streaming media. For example, a target recommendation resource is spliced between the transport stream file 1 and the transport stream file 2 of the target streaming media, and the encoding parameter of the target recommendation resource is different from the encoding parameter of the transport stream file 1 and the encoding parameter of the transport stream file 2.
If no corresponding treatment is performed, when the terminal downloads the transport stream file 1, the target recommended resource and the transport stream file 2 for playing, after the transport stream file 1 is played, because the encoding parameter of the target recommended resource is not consistent with the transport stream file 1, that is, the parameter originally used by the terminal player to decode the transport stream file 1 is not suitable for decoding the target recommended resource, the playing problem of the terminal, such as temporary screen splash, black screen, picture card, etc., may occur, thereby causing poor user experience. Moreover, after the target recommended resource is played, since the encoding parameters of the transport stream file 2 are different from the target recommended resource, the above playing problem may also occur when the transport stream file 2 starts to be played.
Similarly, splicing the target recommended resource into one transport stream file also causes a change in the encoding parameters of the transport stream file, and the above playing problem may also occur unlike other adjacent transport stream files.
To this end, the embodiment of the present application provides a specific way to solve the above situation, that is, when generating the index file, the interruption protocol field is used to indicate the splicing position of the target recommended resource in the target streaming media. Namely, in the index file, the splicing interval of the target recommended resource is identified through the interrupt protocol field.
The interruption protocol field (Discontinuity tag) belongs to the field in the HLS protocol, and is used to mark that the encoding parameters of the transport stream file before and after the streaming media are changed, and instruct the terminal player to reinitialize.
In the embodiment of the application, the interrupt protocol field is introduced into the index file, and the splicing position of the target recommended resource is identified by the interrupt protocol field, so that when the terminal downloads and plays the spliced target streaming media and the target recommended resource through the index file, the player for playing the streaming media is initialized according to the indication of the interrupt protocol field before playing the target recommended resource, the target recommended resource can be smoothly played after initializing the player, and the playing problems of the screen splash and the screen blackout cannot occur. After the target recommended resource is played, the terminal can initialize the player again through the indication of the interrupt protocol field, and then play the subsequent transport stream file, and the playing problem can not occur.
In the embodiment of the application, in addition to introducing the interrupt protocol field to identify the splicing position of the target recommended resource, a segment type field (segmentType) is further used to carry the resource type of the target recommended resource. The terminal can determine the resource type of the target recommended resource through the fragment type field in the index file, so that corresponding processing is facilitated.
Next, by way of specific example, as shown in fig. 1, in the application scenario, two target recommended resources 400 are determined according to the personalized information of the user, and are respectively recommended resource 1 (one advertisement is embedded) and recommended resource 2 (one advertisement is inserted), the target streaming media 300 has four transport stream files, which are transport stream files 1-4, and if the target recommended resources and the target streaming media are spliced, a spliced streaming media is obtained.
Fig. 3 shows specific contents of an index file corresponding to the spliced streaming media in the application scenario. The first 5 rows of the index file are illustrative of the content of the index file, including the version number of the index file, shown as 3; sequence number, shown as 0; the maximum play length of the transport stream file, shown as 15 seconds; and the type of target streaming media, illustratively Video On Demand (VOD).
And then sequentially identifying the transport stream files of the spliced streaming media according to the playing sequence.
First, a transport stream file 1 (i.e., video1.ts) is described, and the playback length is 12.458 seconds.
The transport stream file 2 is described later with the recommended resource 1 (i.e., the aforementioned embedded advertisement) embedded therein, and the beginning and end of this section employ the interrupt protocol field "# EXT-X-DISCONTINUITY" to serve as a function of identifying the splicing position of the recommended resource 1. And identifies the resource type of the recommended resource 1 as the instrumentation class by the segment type field "segmentType ═ 1".
After describing the transport stream file 3 (i.e., video3.ts), describing the recommended assets 2 (i.e., the aforementioned ads), the recommended assets 2 are spliced between the transport stream file 3 and the transport stream file 4 as a complete transport stream file, and the start and end of this part use the break protocol field to serve as an identifier of the splicing location of the recommended assets 2. And identifies the resource type of the recommended resource 2 as an intermediate class by the segment type field "segmentType ═ 2".
