Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Fig. 1 is a flowchart illustrating a method for playing and processing a live video according to an embodiment of the present invention, where the method is applicable to a streaming server, and the present invention is not limited thereto. As shown in fig. 1, the method includes:
and step S101, acquiring a live video recommendation list.
Under the general condition, the user can be interested in live video that the hot recommends relatively, and in the current mode, after the streaming server received the broadcast request of the live video stream that the watching end initiated, at first need to request the live video stream to the anchor terminal that corresponds, the watching end just can normally broadcast the live video after need waiting for a period of time so, and the first screen loading time of the live video is longer, can lead to the user to watch the experience variation of the hot live video. Based on this, the method of this embodiment is specifically improved for the playing processing procedure of live video recommended at a hot stage.
In practical application, a business party can count hot live video information to form a live video recommendation list, namely a hot video list, according to factors such as click quantity, comment quantity, audience interaction quantity and the like of a live video, and regularly updates the live video recommendation list. Therefore, the live video recommendation list counted by the service party can be obtained by linking the service party. Of course, the live video recommendation list may also be obtained by statistics performed by the streaming server itself. It should be noted that the above manner of obtaining the live video recommendation list is only for exemplary purposes, and the present invention is not limited thereto.
And S102, according to the information of each live video contained in the live video recommendation list, the analog watching end requests each live video stream from the anchor end of each live video.
As the name implies, the analog viewing end is not a real end for playing the live video, for example, the analog viewing end may be an automatic triggering program, which is automatically triggered after acquiring the live video recommendation list, and after being triggered, requests each live video stream from the anchor end of each live video according to information of each live video included in the live video recommendation list. In short, the analog viewer is used to simulate the operation of the user to play each live video included in the live video recommendation list, that is, simulate the initiation of a play request for each live video included in the video recommendation list, and may be configured in a streaming service.
The simulation watching end can continuously request the live video stream from the anchor end of each live video, that is, once the live video recommendation list is obtained, the simulation watching end always keeps a successful connection state with the anchor end of each live video contained in the live video recommendation list, and then the simulation watching end requests the live video stream of the live video from each anchor end in real time; alternatively, the analog viewer may periodically request a live video stream from the anchor terminal for each video. Of course, this is merely an alternative embodiment of the present invention and the present invention is not limited thereto.
And step S103, updating and storing the latest stream data of each live video stream in the cache.
In the method, a cache is opened in the streaming server for updating and storing the latest streaming data of each live video stream. For example, for each live video stream, the latest streaming data buffered may be the streaming data of the live video stream uploaded by the anchor for a short time before the current time.
Taking the timing request as an example, after the analog viewer requests for the first time, the stream data requested by the analog viewer from the anchor terminal in the time period of 12:00:00-12:00:59 (marked as the first time period) is stored in the buffer; in the time period of 12:01:00-12:01:59, the simulation watching end stops requesting the streaming data from the main broadcasting end; the analog viewer then initiates a second request at 12:02:00 until 12:02:59 stops requesting streaming data from the anchor. Sequentially deleting the stream data requested in the first time period stored in the buffer, and sequentially buffering the stream data requested in the second time period, wherein the sequential order refers to the order of the timestamps of the video frames in the stream data, thereby realizing the updating of the stream data in the buffer. This is merely an example and the present invention is not limited thereto.
And step S104, receiving a playing request of any live video stream in the live video streams sent by the real watching end, and sending the latest cached stream data of the live video stream to the real watching end in advance.
Corresponding to the analog viewing end, the real viewing end is an end capable of playing the live video for the user to view, for example, an APP capable of providing the live service. And the real watching end sends a playing request of the live video stream to the stream server according to the detected user operation.
Specifically, by judging live video information carried in a received live video stream playing request, it is determined that the playing request sent by a real viewing end is not a playing request for any live video stream in each live video stream, that is, it is determined that the playing request initiated by the real viewing end is not a playing request for any live video contained in a live video recommendation list; if so, the latest stream data of the cached requested live video stream is issued to the real watching end in advance, so that the real watching end can play the live video after decoding the stream data.
Briefly, the video recommendation list is taken in advance, then, for each live video contained in the video recommendation list, a playing request for the live video is initiated in a simulation mode, so that streaming data of a live video stream is requested from a main broadcasting end corresponding to the live video, and the streaming data uploaded by the main broadcasting end due to the fact that the main broadcasting end responds to the simulation playing request initiated by the simulation watching end is cached. If the live video requested to be played by the user belongs to the live video recommendation list, corresponding stream data is directly extracted from the cache and issued to the watching end, and the watching end decodes the received stream data to play the video. In the prior art, after a user initiates a play request of a live video stream, a stream server requests the corresponding anchor terminal for the live video stream, and after the anchor terminal uploads the stream data of the live video stream to the stream server, the stream server issues the stream data to a watching terminal. Therefore, the method can greatly reduce the first screen loading time of the live video and optimize the first screen loading effect.
In summary, in the manner of this embodiment, a play request for each live video corresponding to the live video recommendation list is initiated through simulation, so as to obtain latest streaming data of each recommended live video and cache in the streaming server, and when a play request for each recommended live video included in the live video recommendation list initiated by a viewing end is received, the streaming server directly issues the latest streaming data of the cached recommended live video.
Fig. 2 is a flowchart illustrating a method for playing and processing a live video according to another embodiment of the present invention, where the method of this embodiment is applied to a streaming server, and of course, the present invention is not limited to this, and as shown in fig. 2, the method includes:
step S201, obtaining a live video recommendation list at regular time according to the second timing time.
Under the general condition, the user can be more interested in the video that the hot is recommended, and in the current mode, stream server after receiving the broadcast request of watching the live video stream of end, again to the live video stream of anchor terminal request that corresponds, so the watching end just can normally broadcast the live video after need waiting for a period of time, and live video's first screen load time is longer, can lead to the user to watch the experience variation of hot live video. Based on this, the method of this embodiment is specifically improved for the playing process of the popular live video.
In practical application, a business party can count popular live video information to form a live video recommendation list according to factors such as click quantity, comment quantity, audience interaction quantity and the like of live videos, and the live video recommendation list is updated regularly. Therefore, the live video recommendation list counted by the service party can be obtained by linking the service party. Specifically, the live video recommendation list is obtained at regular time according to the second timing time, and the live video recommendation list obtained at regular time can be synchronous with the live video recommendation list updated at regular time by the service party.
In addition, the live video recommendation list may also be obtained by statistics performed by the streaming server itself, for example, by performing statistics on click rate, audience amount, and the like of each live video, the live video recommendation list is obtained. Then, the above factors of each live video are counted regularly, and the live video recommendation list is updated according to the counting result. It should be noted that the above listed manners for obtaining the live video recommendation list are only for exemplary purposes, and the present invention is not limited thereto.
And S202, authenticating the identity of the analog viewing end by using the analog authentication data.
As the name implies, the analog viewing end is not a real end for playing the live video, for example, the analog viewing end may be an automatically triggered program configured in the streaming server, and the analog viewing end is used for simulating an operation of the user for playing each live video included in the live video recommendation list, that is, simulating to initiate a play request for each live video included in the video recommendation list.
The simulation watching end can be regarded as a common user, the common user needs to authenticate the identity of the common user when requesting to play the live video, and similarly, if the simulation watching end requests to play the live video, the identity of the simulation watching end also needs to be authenticated, specifically, the identity of the simulation watching end is authenticated by using the simulation authentication data, wherein the simulation authentication data can include: simulating a user account and simulating a user password.
Step S203, according to the information of each live video contained in the live video recommendation list, the analog watching end respectively requests each live video stream from the anchor end of each live video according to the first timing time.
The time interval corresponding to the first timing time may be smaller than the interval of the second timing time. For example, the time interval corresponding to the second timing time for acquiring the live video recommendation list is 10 minutes, and the time interval corresponding to the first timing time for requesting the live video stream by the analog viewing end is 1 minute.
That is to say, the analog viewing end requests a live video stream from the anchor end of each live video according to a certain period, and after the live video recommendation list is obtained, the analog viewing end is sometimes connected or disconnected with the anchor end of each live video, and when the duration of the connected state reaches a certain threshold, the connection is disconnected; when the duration of the disconnection state reaches a certain threshold, the connection is reestablished, and so on. For example, if the analog viewing end initiates a first request at 12:00:00, then in the time period of 12:00-12:00:59, the analog viewing end is communicated with each anchor end, and the analog viewing end requests each live video stream from the anchor end; in the time period of 12:01:00-12:01:59, the analog watching end is disconnected with each anchor end, and the analog watching end stops requesting each live video stream from the anchor end; the analog viewing end initiates a second request at 12:02:00, and then in the time period of 12:02:00-12:02:59, the analog viewing end is communicated with each anchor end to request the live video stream from the anchor end, and so on. The timing request mode can save network resources consumed by data transmission.
In addition, the analog viewing end can continuously request the live video stream from the anchor end of each video, that is, once the live video recommendation list is obtained, the analog viewing end is always in a state of being connected with the anchor end of each live video contained in the live video recommendation list, and then each anchor end can continuously upload the stream data of each live video stream. The continuous request mode can ensure that the cached streaming data is closer to real-time streaming data, so that the real-time performance of the live video is higher, and the scheme of the invention is not limited by the method.
And step S204, updating and storing the latest stream data of each live video stream in the cache.
In the method, a cache is opened in the streaming server for updating and storing the latest streaming data of each live video stream. In the above example, after the first request of the analog viewer, the stream data requested by the analog viewer from the anchor terminal in the time period of 12:00:00-12:00:59 is stored in the buffer; and the simulated watching end initiates a second request at 12:02:00, and then in the time period of 12:02:00-12:02:59, the stream data requested by the simulated watching end in the time period of 12:00:00-12:00:59 stored in the buffer is deleted in sequence, and the stream data requested by the simulated watching end in the time period of 12:02:00-12:02:59 is buffered in sequence, wherein the sequence refers to the sequence according to the time stamps of all video frames in the stream data, so that the stream data in the buffer is updated.
Besides buffering the stream data according to the time period, the stream data can be buffered according to the video frames contained in the stream data, specifically, the video frames of the latest n GOPs of the live video stream are buffered. The method comprises the steps that a simulation watching end requests each anchor end for live broadcast video streaming according to first timing time, no matter how much streaming data are requested in a time period when each simulation watching end is communicated with the anchor end, only the video frames of the latest n GOPs in the requested streaming data are cached, and the value of n can be set according to the requirements of service scenes, for example, the higher the fluency requirement is, the larger the value of n is set; the higher the real-time requirement, the smaller the value of n is set.
Further, in the method of the embodiment, an effective storage duration is set for the latest stream data of each live video stream stored in the cache; and if the non-update time length of the latest stream data of any live video stream stored in the cache exceeds the effective storage time length, deleting the latest stream data of the live video stream.
The latest stream data of the cached live video streams in the two situations can be deleted according to the effective storage duration. The first is a live video stream that previously belonged to a live video recommendation list and then did not belong to the live video recommendation list; the second is a live video stream that has been off-air. The following is specifically explained:
the first case: since the analog watching end specifically requests which live video stream is guided by the live video recommendation list acquired at regular time, when a live video does not belong to the popular live video any more, in order to save storage space, the latest stream data of the cached live video stream which does not belong to the popular live video any more needs to be deleted. In this embodiment, whether to delete the live video stream is specifically determined according to the non-updated time length of the latest stream data of the live video stream. For example, if the live video recommendation list acquired for the first time includes the live video a, storing the latest stream data of the live video stream of the updated live video a in the cache; and the live video recommendation list acquired for the second time does not include the live video A, from then on, the simulation watching end does not request the live video A's live end for the latest streaming data of the live video A, the cached latest streaming data of the live video A is not updated, and when the un-updated time length of the cached latest streaming data of the live video A exceeds the effective storage time length, the cached latest streaming data of the live video A is deleted.
The second case: in a time period between two adjacent times of acquiring live video recommendation lists, for example, in a time period after a live video recommendation list is acquired for the first time and before a live video recommendation list is acquired for the second time, if the latest stream data of a live video stream stored in a cache is not updated for a long time, it is indicated that a new stream data has not been generated at a main broadcast end corresponding to the live video stream for a long time, the main broadcast end has stopped playing, and as a video live scene, it has no meaning to continue to cache the stream data of the live video stream that has been stopped playing, so if the latest stream data of any live video stream stored in the cache is not updated for a certain time, the latest stream data of the live video stream is deleted.
In summary, in this embodiment, by setting the effective storage duration, the stream data of the live video stream stored in the cache is cleared at regular time according to the effective storage duration, so that the storage space can be saved.
Step S205, receiving a play request of any live video stream in the live video streams sent by the real watching end, and issuing the latest buffered stream data of the live video stream to the real watching end in advance.
Corresponding to the analog viewing end, the real viewing end is an end capable of playing the live video for the user to view, for example, an APP capable of providing the live service. And the real watching end sends a playing request of the live video stream to the stream server according to the detected user operation.
Specifically, by judging live video information carried in a received live video stream playing request, it is determined that the playing request sent by a real viewing end is not a playing request for any live video stream in each live video stream, that is, it is determined that the playing request initiated by the real viewing end is not a playing request for any live video contained in a live video recommendation list; if so, the latest stream data of the cached requested live video stream is issued to the real watching end in advance, so that the real watching end can play the live video after decoding the stream data.
Particularly, when the latest stream data of the cached live video stream is the latest n GOPs, the latest stream data is issued with the first video frame of the n GOPs as the top screen frame, and since the first video frame of the GOPs is the key frame, in this case, after the n GOPs are issued to the real playing end, the real playing end can quickly decode the stream data, thereby playing the video. Therefore, the time for loading the first screen of the live video can be further reduced in a mode of caching n GOPs.
Step S206, requesting the live video stream from the anchor terminal of the live video stream in real time, and sending the live video stream to the real watching terminal.
And after the latest cached stream data of the live video stream is issued to the real watching end, requesting the live video stream from the main broadcasting end of the live video stream in real time, and issuing the live video stream to the real watching end in real time so that the real watching end plays a real-time live video.
The method of this embodiment is described below with a simple example, where the time interval corresponding to the second timing time is set to 10 minutes, that is, a live video recommendation list is obtained every 10 minutes; the time interval corresponding to the first timing time is 1 minute, namely the analog watching end requests the anchor end for live video stream every 1 minute, and the effective storage time is 2 minutes. The live video recommendation list obtained for the first time comprises a live video A, a live video B and a live video C, and from this moment (recorded as a first moment), the analog watching end requests a live video stream from a main broadcasting end of the live video A, the live video B and the live video C every minute, and updates the latest stream data of each live video stream in a cache; the method comprises the steps that a live video B stops playing after one minute from the first moment, the latest stream data of a live video stream of the live video B cannot be updated after one minute, the non-updating duration of the latest stream data of the live video B reaches two minutes after three minutes from the first moment, and the latest stream data of the cached live video stream of the live video B is deleted;
ten minutes later, acquiring a live video recommendation list for the second time, wherein the live video recommendation list acquired for the second time comprises a live video A, a live video D and a live video E, from the moment (recorded as a second moment), the analog watching end requests a live streaming video from a main broadcasting end of the live video A, the live video D and the live video E at intervals of one minute, and updates the latest stream data of the live video streams of the live video a, the live video D, and the live video E in the buffer, and at the same time, since the live video C does not belong to the live video recommendation list any longer, and the live video stream is not requested from the anchor terminal of the live video C any longer, the latest streaming data of the live video stream of the cached live video C is not updated any longer, and the latest streaming data of the live video stream of the cached live video C is deleted after two minutes from the second moment.
In summary, in the manner of this embodiment, a play request for each live video corresponding to a live video recommendation list is initiated through simulation, so as to obtain latest streaming data of each recommended video and store the latest streaming data in a cache of a streaming server, and update the latest streaming data of each recommended video at a fixed time.
