Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The method provided by the embodiment of the application is applied to an interactive scene for controlling streaming media videos between WEB client equipment (provided with WEB client software, such as a WEB browser) and server equipment (such as an HTTP server). The WEB client device may be installed with WEB client software, such as a WEB browser; the WEB client devices include, but are not limited to, smart phones, tablet computers, notebooks, desktop computers, monitors, and the like. Optionally, the server device may be an HTTP server based on the hypertext transfer protocol HTTP, or may also be any other device that meets the actual use requirement. In actual implementation, the WEB client device and the server device may be specifically determined according to actual use requirements, and the embodiment of the present application is not limited.
Referring to fig. 1, fig. 1 is a flowchart illustrating an implementation of a method for controlling streaming media service interaction according to an embodiment of the present application.
S11: the WEB client equipment sends a first session request message to the server equipment, and the server equipment receives the first session request message.
In this embodiment of the application, when a user needs to request a video or broadcast a video on demand through a WEB client device, the user may operate WEB client software (e.g., a video player) in an electronic device to trigger the WEB client device to send a first session request message to a server device.
Wherein the first session request message is for requesting first streaming media data and the first session request message indicates a target function. That is, the WEB client device requests to establish a session for controlling streaming media video playing with the server device through the first session request message, that is, requests for streaming media service. Wherein the session may be a session for a video-on-demand service or a live video service.
Taking the establishment of a session for the video-on-demand service as an example, the first streaming media data is streaming media data for live video broadcast, and accordingly, the first session request message may be used to indicate to start live video broadcast, and may also be used to indicate to stop live video broadcast. It is to be understood that the target function may be a function of controlling the video to start playing, or may be a function of controlling the video to stop playing. Of course, the target function may also be any other possible function, which may be determined according to actual usage requirements, and the embodiment of the present application is not limited.
Taking the establishment of a session for a live video service as an example, the first streaming media data is streaming media data for video on demand, and accordingly, the first session request message may be used to instruct to open a video on demand, may also be used to instruct to stop the video on demand, or may be used to instruct to fast forward or fast rewind to control playing; or may be used to instruct positioning control play. It is understood that the target function includes any one of: the video playing control method comprises the functions of controlling video playing to start, controlling video playing to stop, controlling video fast-forward playing, controlling video fast-backward playing and controlling video positioning playing. Of course, the target function may also be any other possible function, which may be determined according to actual usage requirements, and the embodiment of the present application is not limited.
S12: and the server-side equipment determines a first session response message according to the first session request message.
Wherein the first session response message comprises first streaming media data and the first session response message indicates a target function.
Optionally, the first streaming media data is video frame data obtained by block-coding streaming media data by the server device. That is, the first streaming media data is a video stream composed of a plurality of video frames.
In this embodiment of the application, the HTTP server may package the video frame according to an HTTP Chunked encoding format to obtain the first streaming media data.
For example, the server device may add a Transfer-Encoding (Transfer-Encoding) to the HTTP response header (Body) by using an HTTP Chunked block Encoding technique, that is: chunked, Body payload takes Elementary Streams (ES) (called ES streams). The Chunked block coding technology has a sub-packaging mechanism: chunked encoding is formed by connecting a plurality of blocks (Chunk) in series, and is marked by a Chunk with a length of 0 to end. Each Chunk is divided into a head part and a text part, the head part content indicates the character size of the next text, the text part is the actual content with the specified length, and the two parts are separated by carriage return and line feed. The streaming media service belongs to a persistent service, the video stream is always transmitted, and the length of the video stream is unknown in advance.
Optionally, the HTTP server device may utilize a chunk block encoding technique to pack each video frame into an FMP4 format (MSE interface specification), which is used as a payload of HTTP and transmitted in HTTP-chunk. If the frame is too small (i.e., less than the preset threshold), the HTTP server device may combine multiple, e.g., P-frames Chunked into one HTTP response packet (referred to as HTTP Chunked packet).
S13: and the server side equipment sends a first session response message to the WEB client side equipment, and the WEB client side equipment receives the first session response message.
Optionally, in combination with the content described in S12, the server device may perform block coding on the first streaming media data, and transmit the block-coded first streaming media data to the WEB client device in a block manner.
Optionally, the first session response message may further include a first session identifier, where the first session identifier is an identifier generated when the server device establishes a session according to the first session request message. The first session identification may be an identification associated with the first streaming media data. After receiving the first session response message sent by the server device, the WEB client device sends a second session request message to the server device, where the second session request message includes the first session identifier. Accordingly, the server device receives the second session request message, and the server device may perform session identification according to the first session identifier, for example, the server device may recognize that the session is a session for the first streaming media data.
Illustratively, since the HTTP protocol itself is a stateless connection protocol, and the streaming media service belongs to a multi-request associated service and has a session state, the HTTP server device may generate a unique session identifier (denoted as SessionID) for the session when establishing the session with the WEB client device for the first session request message sent by the WEB client device, and return the session identifier to the WEB client device through the Set-Cookie entry added to the response header. In this way, for the subsequent request message of the same session, the HTTP server device may obtain the SessionID from the Set-Cookie. Correspondingly, the HTTP server device may determine whether the received session request message carries the SessionID, so as to determine whether the session request message belongs to the same session, that is, if the first session request message and the second session request message both carry the SessionID, the server device may determine that the first session request message and the second session request message belong to the same session.
Illustratively, in a case where the WEB client device receives the first session response message, the WEB client device may parse the first session response message, and obtain the first streaming media data and the target function indicated by the first session response message.
S14: and the WEB client equipment calls a target application program interface corresponding to the target function according to the first session response message.
The target application program interface may be an interface defined for a target function based on a micro service architecture.
Optionally, in this embodiment of the application, the WEB client device may invoke, according to the target function indicated by the first session response message, a target application program interface of HTML5 MSE corresponding to the target function.
Optionally, before the WEB client device sends the first session request message to the server device, the WEB client device may store the first corresponding relationship between the target function and the target application program interface, so that the WEB client device can call the target application program interface corresponding to the target function as needed at any time.
Further optionally, the WEB client device may invoke, according to the first session response message and the first corresponding relationship, a target application program interface corresponding to the target function from a plurality of application program interfaces stored in advance.
S15: and the WEB client equipment controls the playing of the first streaming media data according to the target application program interface.
Illustratively, after the WEB client device acquires the first streaming media data and the target function indicated by the first session response message, the WEB client device may call a target application program interface corresponding to the target function according to the target function indicated by the first session response message, and play the first streaming media data according to the target application program interface.
Illustratively, the WEB client device may parse the http chunk packet, and directly call the parsed data to an interface of the HTML5 MSE, so as to play the first streaming media data.
As described above, if the target functions are different, the corresponding target application program interfaces are different, and the specific implementation manner of the WEB client device controlling the playing of the first streaming media data according to the target application program interfaces is different. By way of example (e.g., the following means one to seven), a possible implementation manner of controlling the playing of the first streaming media data by the WEB client device according to the target application program interface is described below.
In a first manner, assuming that the first streaming media data is streaming media data for live video broadcasting, and the target function is a function of controlling video to start playing, the WEB client device controls the first streaming media data to start playing according to a target application program interface corresponding to the target function.
For example, if the user clicks a start live broadcast mark in the live broadcast interface, the WEB client device sends a first session request message (indicating to start live broadcast) to the server device, and receives a first session response message (indicating to start live broadcast), and the WEB client device calls a corresponding target application program interface according to the first session response message to start live broadcast of a video.
In a second mode, assuming that the first streaming media data is streaming media data for live video broadcasting, and the target function is a function of controlling video to stop playing, the WEB client device controls the first streaming media data to stop playing according to a target application program interface corresponding to the target function.
For example, if the user clicks a live broadcast stop mark in the live broadcast interface, the WEB client device sends a first session request message (indicating to stop live broadcast) to the server device, and receives a first session response message (indicating to stop live broadcast), and the WEB client device calls a corresponding target application program interface according to the first session response message to stop live broadcast of the video.
And if the first streaming media data is streaming media data for video on demand and the target function is a function of controlling video to start playing, the WEB client device controls the first streaming media data to start playing according to a target application program interface corresponding to the target function.
For example, if the user clicks a play flag in the video interface, the WEB client device sends a first session request message (indicating to play a video) to the server device, and receives a first session response message (indicating to play a video), and the WEB client device calls a corresponding target application program interface according to the first session response message to play the video.
And if the first streaming media data is streaming media data for video on demand and the target function is a function of controlling video to stop playing, the WEB client device controls the first streaming media data to stop playing according to a target application program interface corresponding to the target function.
For example, if the user clicks the stop playing flag in the video interface, the WEB client device sends a first session request message (indicating to stop playing the video) to the server device, and receives a first session response message (indicating to stop playing the video), and the WEB client device calls the corresponding target application program interface according to the first session response message to stop playing the video.
And if the first streaming media data is streaming media data for video on demand and the target function is a function of controlling video fast-forward playing, the WEB client device controls the first streaming media data to fast-forward play according to a target application program interface corresponding to the target function.
For example, if the user clicks a 1.5-time fast forward flag in the video interface, the WEB client device sends a first session request message (indicating 1.5-time fast forward) to the server device and receives a first session response message (indicating 1.5-time fast forward), and the WEB client device calls a corresponding target application program interface according to the first session response message to control the video to fast forward and play at 1.5-time speed.
And in a sixth mode, assuming that the first streaming media data is streaming media data for video on demand, and the target function is a function of controlling video fast-rewind playing, the WEB client device controls the first streaming media data to fast-rewind playing according to a target application program interface corresponding to the target function.
For example, if the user clicks a 2-time fast-rewinding mark in the video interface, the WEB client device sends a first session request message (indicating 2-time fast-rewinding) to the server device, and receives a first session response message (indicating 2-time fast-rewinding), and the WEB client device calls a corresponding target application program interface according to the first session response message to control the video to be played at 2-time fast-rewinding.
And in a seventh mode, assuming that the first streaming media data is streaming media data for video on demand, and the target function is a function of controlling video positioning and playing, the WEB client device controls the first streaming media data to be positioned and played according to a target application program interface corresponding to the target function.
For example, if the user slides on the progress bar in the video interface (for example, slides to the first location point), the WEB client device sends a first session request message (indicating that the video starts to be played from the first location point) to the server device and receives a first session response message (indicating that the video starts to be played from the first location point), and the WEB client device calls the corresponding target application program interface according to the first session response message to control the video to start to be played from the first location point.
Of course, in addition to the above-mentioned first to seventh modes, there are other modes such as pausing to play the video and continuing to play the video, which may be determined according to the actual use situation, and the embodiment of the present application is not limited.
In the embodiment of the application, the WEB client device and the server device establish a session according to the first session request message, and the WEB client device can call a target application program interface corresponding to the function indicated by the first session request message to perform service interaction with the server device, so as to implement the function indicated by the first session request message. As the target application program interfaces of the WEB client equipment and the server equipment are defined aiming at different video playing functions, the interface compatibility of the WEB browser for playing the video is improved. Because the interface is an HTTP protocol, the existing WEB server can support the interface by multiplexing or slightly modifying, and the interconnection and intercommunication between WEB client equipment and server equipment of different manufacturers are facilitated.
In the embodiment of the application, for an interface of a streaming media service, an restful idea may be adopted to design the interface, and a video resource is used as a Unique Identifier (UID) to be marked, and the UID is operated by using an HTTP request manner (e.g., a POST request, a GET request, a PUT request, a DELETE request, etc.), including main functions of a live broadcast service and an on-demand service, such as start of play, stop of play, fast rewind, fast forward, positioning, etc.
In this embodiment of the present application, the functions indicated by different session request messages may correspond to different interface definitions. The following describes interface definitions corresponding to the respective functions, corresponding to the above-described first and seventh aspects.
First, for a session request message for instructing to open a live video function, an embodiment of the present application defines an interface definition shown in table 1 below. Specifically, the WEB client device may invoke an interface corresponding to the function indicated by the session request message according to the first session identifier, and perform a session with the server device, so as to open a live video function. A Uniform Resource Identifier (URI) in the following table is a character string for identifying a name of a certain internet resource.
In a second way, for a session request message for instructing to stop the live video function, the interface definition shown in table 2 below is defined in the embodiment of the present application. Specifically, the WEB client device may invoke an interface corresponding to the function indicated by the session request message according to the first session identifier, and perform a session with the server device, so as to implement a function of stopping live broadcasting of video.
TABLE 2
Third, for the session request message for instructing to open the video-on-demand function, the embodiment of the present application defines an interface definition as shown in table 3 below. Specifically, the WEB client device may invoke an interface corresponding to the function indicated by the session request message according to the first session identifier, and perform a session with the server device, so as to implement a function of opening a video-on-demand.
TABLE 3
In a fourth way, for the session request message used for instructing to stop the video-on-demand function, the embodiment of the present application corresponds to the interface definition shown in table 4 below. Specifically, the WEB client device may invoke an interface corresponding to the function indicated by the session request message according to the first session identifier, and perform a session with the server device, so as to implement a function of stopping video-on-demand.
TABLE 4
In a fifth mode and a sixth mode, for a session request message for instructing a fast forward or fast reverse control play function, the interface definition shown in table 5 below is defined in the embodiments of the present application. Specifically, the WEB client device may invoke an interface corresponding to the function indicated by the session request message according to the first session identifier, and perform a session with the server device, so as to implement a fast forward or fast backward control playing function.
It should be noted that, for the function of controlling playback of fast forward and fast backward, fast forward and fast backward belong to operations after session establishment, SessionID is returned by the response header of the server device only when a session is first created, and the following operations are all operations in which SessionID is set in the request header, so that the server device specifies that this belongs to a session (i.e., a group of related operations).
TABLE 5
Seventh, for a session request message indicating a positioning control video playing function, the interface definition shown in table 6 below is defined in the embodiment of the present application. Specifically, the WEB client device may invoke an interface corresponding to the function indicated by the session request message according to the first session identifier, and perform a session with the server device, so as to implement a function of positioning and controlling video playing.
The positioning control video playing refers to that the server-side equipment finds the video frame at any time. For example, in a monitoring application, a video is required to be searched, and the video is directly positioned according to the time of a case probably happening.
It should be noted that, for the function of opening the on-demand video, the on-demand operation generates a start time timestamp or an end time timestamp, which can be specified by the user in the request line.
In the following, a possible implementation manner of the method for controlling streaming media service interaction provided by the embodiment of the present application is exemplarily described in combination with the first embodiment (live video) and the second embodiment (video on demand).
The first embodiment is as follows:
fig. 2 below shows a schematic view of a live broadcast interaction flow implemented by a WEB client device and a server device (e.g., an HTTP server) by using the method provided by the embodiment of the present application.
As shown in fig. 2, the WEB client device and the HTTP server are in live broadcast interaction based on the restful interface. For example, taking a WEB client device as an example, a session is created through POST to receive a streaming media video transmitted by a server device, the streaming media video is analyzed, and the streaming media video is played by using a native MSE interface of a browser. Finally, when the playing is stopped, the session is stopped through the restful interface DELETE, and the server will not transmit the streaming media video.
In detail, with reference to fig. 2, the WEB client device sends a session request message to the server device, so as to establish a session of live video with the HTTP server and implement a function related to live video. For example, the first session request message may be a session request message for instructing to open a live video (i.e., a target function), or a session request message for instructing to stop a live video (i.e., a target function).
Correspondingly, the HTTP server receives the first session request message, generates a first session identifier according to the first session request message, packages the video frame according to the HTTP chunk format to obtain a first streaming media video, and then sends the first streaming media video and the first session identifier to the WEB client device through the first session response message.
Correspondingly, the WEB client device can analyze the obtained video frame, call the application program interface corresponding to the target function according to the first session response message, and perform a session with the server device, so as to implement the function indicated by the first session request message. For example, if the first session request message is used to instruct to open a live video function, the WEB client device may invoke an interface corresponding to the function indicated by the first session request message, perform a session with the server device, and implement opening the live video function (e.g., invoke an MSE interface to play a video). Or, if the first session request message is used to indicate that the live video function is stopped, the WEB client device may call an interface corresponding to the function indicated by the first session request message to perform a session with the server device, so as to stop the live video function.
Because the streaming media service belongs to a continuous service, the streaming media video is transmitted all the time without stopping, and the length of the streaming media video is unknown in advance, the process of realizing the live broadcast interaction between the WEB client device and the server device can be realized by circularly adopting the method provided by the embodiment of the application.
Example two:
fig. 3 below shows a schematic flow chart of on-demand interaction between a WEB client device and a server device (e.g., an HTTP server) implemented by using the method provided by the embodiment of the present application.
As shown in fig. 3, the WEB client device and the HTTP server interact on demand based on the restful interface. For example, taking a WEB client device as an example, a session is created through POST (at this time, a session request message carries a corresponding timestamp), a video stream transmitted by a server device is received, the video stream is parsed, and a native MSE interface of a browser is used to play the video stream. Or sending a session request message for fast forwarding, fast rewinding or pausing to the HTTP server (at this time, the session request message carries a corresponding value), receiving a video stream transmitted by the server device, parsing the video stream, and calling an interface to implement the functions of fast forwarding, fast rewinding or pausing indicated by the session request message. Finally, when the playing is stopped, the session is stopped through the restful interface DELETE, and the server will not transmit the video stream.
In the embodiment of the application, the WEB client device sends the first session request message to the server device, so that a video-on-demand session is established with the HTTP server and the function related to the video-on-demand is realized. For example, the first session request message may be a session request message for instructing to open a video-on-demand (i.e., a target function), or a session request message for instructing to stop a video-on-demand (i.e., a target function), or a session request message for instructing to fast forward and fast reverse control play.
Correspondingly, the HTTP server receives the first session request message, generates a first session identifier according to the first session request message, packages the video frame according to the HTTP chunk format to obtain a video stream, and then sends the video stream and the first session identifier to the WEB client device through the first session response message.
Correspondingly, the WEB client device may parse the video frame to obtain a video frame, and call an interface corresponding to the function (i.e., the target function) indicated by the first session request message according to the first session response message, to perform a session with the server device, so as to implement the function indicated by the first session request message. For example, if the first session request message is used to indicate to open a video-on-demand function, the WEB client device may call an interface corresponding to the target function to perform a session with the server device, so as to open the video-on-demand function (e.g., call an MSE interface to play a video). Or, if the first session request message is used to instruct to stop the video-on-demand function, the WEB client device may call an interface corresponding to the target function to perform a session with the server device, thereby implementing the video-on-demand stop function. Or, if the first session request message is used to indicate a fast-forward and fast-backward control playing function, the WEB client device may call an interface corresponding to the target function to perform a session with the server device, thereby implementing the fast-forward and fast-backward control playing function.
Because the streaming media service belongs to a continuous service, the video stream is transmitted all the time without stopping, and the length of the video stream is unknown in advance, the process of realizing the on-demand interaction between the WEB client device and the server device can be realized by circularly adopting the method provided by the embodiment of the application.
The streaming media service designed based on the RESTFull architecture has the characteristics of cross-platform and cross-browser because the RESTFull interface is based on the HTTP protocol, and the RESTFull architecture is applied to non-streaming media and belongs to the mainstream technology. Because the interface is an HTTP protocol, the existing WEB server can support the interface by multiplexing or slightly modifying, and the interconnection and intercommunication between WEB client equipment and server equipment of different manufacturers are facilitated.
