Description
Technical Field
The present invention relates to the field of computer technologies, and in particular, to a video playing method and apparatus.
Background
In the existing video playing scheme, a streaming media server decodes and transcodes a video in an h.265 coding format into a video in an h.264 format, and then transmits the video to a front-end browser for playing. Because h.265 has a higher compression rate than h.264, decoding requires a higher performance requirement, most of the current computer CPU soft decoding (i.e. software decoding) h.265 high-definition video is still more laborious, and hardware compatibility is also not good, so few browsers originally supporting h.265 decoding are available. There are also front-end video components that are played by h.265 decoding with pure js or wasm schemes, but js or wasm performance is significantly weaker than the decoding capability of c language in the browser native video tag < video/>.
In the process of implementing the invention, the inventor finds that at least the following problems exist in the prior art:
the video transcoding through the streaming media server consumes a large amount of server performance, increases the server cost, and the size of the transcoded video stream is larger, which is not favorable for network transmission of high-definition videos. The decoding of the streaming media server can increase the use cost of the server and the network transmission time, and is not suitable for scenes such as video real-time monitoring. Some existing browser plug-ins only support parsing of the h.264 encoding format, and for the h.265 encoding format with higher definition and higher compression rate, there is no solution for parsing a video stream in real time to play video pictures. The decoding performance of js or wasm components is weak, and multi-channel high-definition H.265 video cannot be played smoothly.

Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Fig. 1 is a schematic diagram illustrating the main steps of a video playing method according to an embodiment of the present invention.
As shown in fig. 1, the video playing method of the embodiment of the present invention mainly includes the following steps S101 to S102:
step S101: responding to a player window creating command sent by a web page end, creating a player window process, and sending the created player window process to the web page end;
step S102: and after receiving a playing control command sent by the web page end corresponding to the player window process, controlling the player window process to play the video according to the playing control command.
The web page side is the terminal device (e.g., computer) web page side.
In response to a player window creation command sent by a web page side, before creating a player window process, receiving the player window creation command sent by the web page side through establishing a websocket connection, wherein the player window creation command comprises a player size (such as width and height of a player) of a corresponding player window process and a position of the player at the web page side. A websocket is a protocol for full duplex communication over a single TCP connection.
The player window creation command includes a player unique identification.
After creating the player window process, the created player window process may be assigned a corresponding player unique identifier.
Illustratively, the number of player window processes created is plural.
The playing control command comprises a player unique identification corresponding to the player window process to be controlled.
And after receiving a playing control command sent by the web page end corresponding to the player window process, identifying the player window process to be controlled according to the unique player identification included in the playing control command.
After receiving a play control command sent by a web page end corresponding to a player window process, controlling the player window process to play a video according to the play control command, which specifically comprises the following steps: after receiving a play control command sent by a player window process corresponding to the web page end, executing the play control command, and returning a reply message corresponding to the play control command to the web page end according to an execution result of the play control command, so that the web page end executes a corresponding callback function according to the content of the reply message, wherein the callback function comprises predefined operation corresponding to the content of the reply message. The reply message body may carry fields of uuid, errorCode, etc., uuid is the unique identifier of the player, errorCode indicates the execution result, e.g., errorCode is 0 indicating success, 1 indicating failure, -1 indicating interface call failure (player process without uuid identifier), -2 indicating service parameters are illegal, etc. The web page side judges whether the CS main control program successfully executes the play control command through the errorCode. The callback function is written in the web page end in advance, the invention adopts a plan asynchronous programming solution, and the callback function is two parameters of a plan callback object.
The player window process of the embodiment of the present invention decodes the video acquired from the Streaming media server by using the C + + language to play in Real Time, and the video in the Streaming media server may be obtained by Streaming the video data acquired by the camera through a Real Time Streaming Protocol (RTSP Protocol).
Fig. 2 is a functional block diagram of video playback according to one embodiment of the present invention. As shown in fig. 2, the web page calls the CS master program to create a CS player process in the form of creating an iframe, and specifically, the web page may call the CS master program through a front-end script when the page is initialized. The CS master control program is a program for executing the video playing method according to the embodiment of the present invention, and prompts downloading of the CS player if the CS player is not installed on the terminal device. An iframe is an HTML tag that functions as a document within a document, or a floating FRAME (FRAME). The CS player is client playing software according to an embodiment of the present invention, and includes a CS master control program and a CS player process created by the CS master control program, where the CS player process is a player window process described in the above embodiment, and is a player window process based on websocket communication. The websocket is a protocol for full-duplex communication over a single TCP connection, and is used for bidirectional communication between a web page side and a CS side (i.e., a player side) in the solution of the embodiment of the present invention. The CS master program is an intermediate agent for forwarding the websocket message between the web page side and the CS player process.
promise is a solution for asynchronous programming that is more reasonable and more powerful than conventional solutions to call back functions and events. The web page terminal of the embodiment of the invention actively initiates a websocket request through the premium to establish a link with the CS main control program, thereby controlling the creation, position, size, CS player and stop of the CS player. Specifically, the web page side first sends a createWind command, which is a player window creation command, including information such as width and height of a player, a position, and uuid (player unique identifier, which may be a random unique string code). Meanwhile, the web page side creates a { resolve, reject } callback object with this uuid as a key. uuid may be constant over the life cycle of the CS player process. The CS master program adjusts the player window to the corresponding position of the web page by the corresponding parameters (width and height, position, etc. of the player) in the createWind command. The web page end also carries a randomly generated unique character string code (namely a sequence parameter) when sending the websocket message to the CS player every time, and the CS player carries the sequence parameter when replying the websocket command of the web page end and is used for marking a complete life cycle of the websocket command sent from the web page end to the web page end and received the reply.
After receiving a play control command sent by a web page end corresponding to a player window process, the CS main control program executes the play control command, and then feeds back a reply to the web page end corresponding to the play control command, i.e. a reply message corresponding to the play control command, where the reply message body carries fields of uuid, errorCode, etc., where errorCode, for example, 0 indicates success, 1 indicates failure, 1 indicates interface invocation failure (player process without uuid identification), and 2 indicates that service parameters are illegal, etc. The web page side judges whether the CS main control program successfully executes the play control command through the error code, reads the stored premium callback object { resolve, reject } of which the uuid is key, and executes corresponding resolve or reject, thereby executing the callback corresponding to the premium. The resolve and reject are callback functions, which are two parameters of the plan callback object, and call the resolve function when the asynchronous task is successfully completed and the result is returned, and call the reject function when the asynchronous task fails and the reason for failure is returned. The resolve and reject include predefined operations, for example, if the execution of the play control command is successful (errorCode ═ 0), the predefined buried point statistics operation in the resolve function is executed, and if the execution of the play control command is failed (errorCode ═ 1), the predefined failed interface display operation in the reject function is executed.
The web page side can instantiate the player multiple times through the CS master program, that is: and sending the createWind command through websocket connection for multiple times, creating a CS player process for playing video pictures after the CS main control program receives the createWind command every time, distributing a unique uuid to the CS player process in a monitoring scene, such as a monitoring picture, and sending the uuid to a web page end through websocket callback. The method includes the steps that players instantiated at the web page end correspond to unique fixed uuids, each web page sends playing control commands to a CS main control program through a websocket, the playing control commands carry the corresponding uuids, the CS main control program identifies corresponding CS player processes through the uuids and controls the corresponding CS player processes to respond to the corresponding playing control commands, and therefore the effect that the web pages control a plurality of CS player windows is achieved.
The web page end and the CS player process of the embodiment of the invention can have a one-to-many relationship, and the CS main control program can distribute the unique uuid after the CS player process is established and inform the web page end. And the web page side determines the CS player interacting with the web page side through the unique uuid parameter in the websocket response command of the CS player.
The embodiment of the invention avoids the performance bottleneck in the aspect of language of js/Wasm decoding multi-channel high-definition video, the embodiment of the invention uses C + + for decoding, the decoding performance is more excellent, the CS player decodes and plays in the form of a CS client, js (JavaScript, which is a Web programming language) code at the Web page end is responsible for awakening the CS player and interacts through websocket, js scripts respectively control a plurality of CS player windows to be positioned at different positions of the Web page, and the CS player is responsible for fetching, decoding and playing multi-channel high-definition H.265 video, so that the effect similar to the native video is achieved, and the decoding performance of the embodiment of the invention is higher than that of a js/Wasm decoding scheme. The embodiment of the invention can also realize that the CS player plays videos with various formats and supports various streaming modes, compared with the existing streaming media transcoding mode, the embodiment of the invention can reduce the decoding pressure of the streaming media server more greatly and save the server cost.
