It should be noted that, without conflict, the embodiments of the present disclosure and features of the embodiments may be combined with each other.
In the technical scheme of the disclosure, the related processes of collecting, storing, using, processing, transmitting, providing, disclosing and the like of the personal information of the user accord with the regulations of related laws and regulations, and the public order colloquial is not violated.
FIG. 1 illustrates an exemplary system architecture 100 to which embodiments of the web video playback method, apparatus, electronic device, and computer-readable storage medium of the present disclosure may be applied.
As shown in fig. 1, the system architecture 100 may include a display 101 and a host 102, and a medium providing a communication link between the display 101 and the host 102, may include various connection types, such as wired, wireless communication links, or fiber optic cables, among others.
The display 101 is presented as a window of the output content of the host 102 as a user in front of the display 101, and the user can issue other operation instructions to the host 102 according to the content of the display 101, so as to control the host 102 to call the functional hardware formed by the host to complete corresponding operations, such as acquisition, decoding, rendering, and the like, of the video file. Various applications for implementing the above functions, such as a browser-like application, a video-on-demand-like application, and the like, may be installed on the host 102.
The host 102 may provide various services through various built-in applications, for example, a browser-like application that may provide efficient parsing and transcoding services for video on-line on demand through a browser web page, where the host 102 may implement the following effects when running the browser-like application: firstly, receiving a play request for a target video displayed in a web browser, which is sent by a user through an input device connected to a host 102; then, controlling a webpage assembly component to determine an actual coding standard adopted by the target video; then, when the web page player is found not to support the actual coding standard, controlling the target video of the web page assembly component to be converted into the coding standard supported by the web page player, and obtaining a converted target video; and finally, controlling the webpage assembly component to send the converted target video to a webpage player for playing.
The method for playing web page video provided in the following embodiments of the present disclosure is generally performed by the host 102 at the playing end, and accordingly, the web page video playing device is also generally disposed in the host 102.
It should be understood that the number of display screens, hosts in fig. 1 is merely illustrative. There may be any number of displays, hosts, as desired for the implementation.
Referring to fig. 2, fig. 2 is a flowchart of a web video playing method according to an embodiment of the disclosure, where the flowchart 200 includes the following steps:
step 201: determining a target video to be played according to a playing request transmitted by a web browser;
This step is intended for a play request of a target video, which is entered through a web browser by an execution subject of the web video play method (e.g., the host side 102 shown in fig. 1). I.e. the play request is generated by the user selecting for a video on demand page (web site) presented by a web browser, for example presented by the display 101 shown in fig. 1, pointing to the selected target video.
Specifically, the selection information pointing to the target video may take various forms, such as the number, code, location information, etc. of the target video in the current web page, and may also be a unique identity number of the whole network of the video on demand website.
Step 202: the method comprises the steps of controlling a webpage assembly component to determine an actual coding standard adopted by a target video;
On the basis of the determination of the target video in step 201, this step aims to determine the coding standard actually adopted by the target video (hereinafter collectively referred to as the actual coding standard throughout the text) by the above-described execution body control web page assembly component.
The English of the webpage assembly component is called WebAssembly, and the English is abbreviated as: WASM refers to Assembly running on a Web platform, and Assembly refers to Assembly code-instruction code that directly operates the CPU. The assembly code is equivalent to a language that machine code executed by the CPU can be converted into that which is suitable for human reading. A typical compiled execution link is a compiled language such as Cpp, rust, etc. compiled into assembly instructions, which are then converted into binary machine code for reading by the CPU, and other languages such as Java, python, etc. are virtual machines that use a generic set of hardware instructions running in the x86 class, and then execute their own "assembly language" (e.g., java Bytecode). The Web platform is a Java, python-like virtual machine environment on a browser that provides the virtual machine environment to execute some JavaScript (abbreviated JS) or other scripting language. WebAssembly can be regarded as the x86 hardware general instruction set of the Web platform, and is used as a layer of intermediate language, and the upper layer is docked Java, python, rust, cpp, so that the languages can be compiled into a uniform format for the Web platform to operate.
That is, in the conventional manner, the instructions received by the web browser are understood by other scripting languages such as JS, and the tasks for determining the actual coding standard are issued to the WASM component through the upper API written based on the JS language, which involves intermediate operations of language conversion, command conversion, data content conversion, storage location conversion, and the like between the upper scripting language and the lower assembly language, and thus is inefficient. The present disclosure uses the data transmission path established with the WASM component in advance to issue the task to the WASM component through the data transmission path, so as to replace part of JavaScript code by WASM in use, thereby executing the operation of the CPU more efficiently.
Most of common video resources which can be played on browser webpages are obtained by encoding by adopting an H.264 encoding standard, most of browsers or webpage players can support more video files obtained by encoding according to the H.264 encoding standard, but along with the advantage that the H.265 encoding standard can save half of bandwidth compared with the H.264 encoding standard, most of video files begin to gradually replace the H.265 encoding standard, but the browser or webpage player usually has poor support for the encoding standard.
Step 203: responding to the fact that the webpage player does not support the actual coding standard, and controlling the target video of the webpage assembly component to be converted into the coding standard supported by the webpage player to obtain a converted target video;
based on step 202, this step aims to control the web page assembly component target video to be converted into the coding standard supported by the web page player by the execution body when the execution body determines that the web page player does not support the actual coding standard, so as to obtain the converted target video.
For example, when the target video adopts the h.265 coding standard and the web page player is found to not support the h.265 coding standard, the target video can be converted into the h.264 coding standard supported by the web page player by the control web page assembly component, so as to obtain the converted target video obtained by coding according to the h.264 coding standard.
In particular, the various coding standards supported by the web player (e.g., H.264, MPEG, AVC, etc.) may be summarized and recorded as a list or collection to facilitate a determination of whether the actual coding standard belongs to a supported one.
Step 204: and the control webpage assembly component sends the converted target video to a webpage player for playing.
Based on step 203, this step aims to control the web page assembly component to send the converted target video to the web page player for playing by the execution subject, so that the user can see the video content of the converted target video through the web page player.
Aiming at the playing request of the target video transmitted through the web browser, the web video playing method provided by the embodiment of the invention can efficiently determine the actual coding standard adopted by the target video by means of the capability of the web page assembly component to directly interact with the bottom hardware, and convert the target video according to the supported coding standard when the web page player does not support the actual coding standard, so that the web page player can normally play the converted target video, and the playing capability of the web page player is expanded. And because the operation amount of the code standard conversion is very huge, the execution time is shortened by means of the webpage assembly component, and the online video watching experience of a user through a browser webpage is improved.
Referring to fig. 3, fig. 3 is a flowchart of a method for determining an actual encoding standard adopted by a target video according to an embodiment of the present disclosure to enhance understanding of the internal structure of a web page assembly component and how the process is implemented, wherein the flowchart 300 includes the following steps:
step 301: the method comprises the steps of controlling a decapsulation sub-component in a webpage assembly component to decapsulate a target video to obtain data to be decoded;
The step aims at decapsulating the target video by the decapsulation sub-component in the execution body control webpage assembly component to obtain data to be decoded.
Specifically, the decapsulation is to remove a "shell" encapsulated by the video file, for example, converting the format of the video file into the format of FLV, MP4, etc. is equivalent to encapsulating the rendered video data once, where the purpose of the encapsulation is to allow the player to quickly select the correct play kernel to decode and render.
Considering that the target video may be correctly packaged or may be incorrectly packaged, the unpacking subassembly can only take the file extension name of the target video as a reference (because the file extension name can be easily modified) when the unpacking is specifically performed, and is assisted by other parameters (such as recording some information related to the packaging mode in the file header) to complete the correct unpacking together, so that once the unpacking is performed according to the incorrect unpacking mode, the unpacked data is meaningless and cannot be used for presenting corresponding video pictures.
Step 302: and the decoding sub-assembly in the control webpage assembly decodes the data to be decoded, and determines an encoding mode corresponding to the decoding mode used when the decoding is successful as an actual encoding standard.
On the basis of step 301, this step aims to control, by the above-mentioned execution body, the decoding subcomponent in the web page assembly component to decode the data to be decoded, and determine the coding mode corresponding to the decoding mode used when the decoding is successful as the actual coding standard.
Specifically, when the decoding subcomponent can be based on some parameters for determining the coding mode, the coding mode can be determined directly according to the parameters, if the parameters cannot be obtained or the obtained parameters are proved to be unreliable, the actual coding standard can be determined in an attempt mode, and the sign of successful decoding is that the decoded data is not messy code and nonsensical data.
Multiple try threads may be established to expedite the determination efficiency even in support of using multi-threading techniques.
On the basis of the embodiment shown in fig. 3, the present disclosure further specifically provides a method for determining an actual encoding standard adopted by a target video according to a file extension name and file header information through fig. 4, and a flow 400 shown in fig. 4 includes the following steps:
Step 401: controlling a decapsulation sub-component to acquire file extension names and file header information of the target video;
the present step aims at the above-mentioned execution subject control decapsulation sub-component to obtain the file extension name and file header information of the target video, where the file extension name may correspond to the coding standard adopted by the file extension name in some form, and adopting different coding standards will generally record corresponding feature fields in the file header, so that the embodiments of the present disclosure are determined by these two parameters at the same time. The header information has a higher degree of confidence than the file extension that is easier to modify.
Step 402: judging whether the file extension name and the file header information are matched, if so, executing step 403, otherwise, executing step 404;
the file expansion name and the file header information are matched, namely the file expansion name and the file header information are commonly pointed to the same coding standard, and otherwise, the file expansion name and the file header information are not matched.
Step 403: controlling the decapsulation sub-assembly to decapsulate according to the encapsulation mode indicated by the file extension name;
The step is based on the result of the judgment in step 402 that the file extension name and the file header information are matched, and aims to control the decapsulation sub-component to decapsulate according to the encapsulation mode indicated by the file extension name by the execution main body. In practice, since the file extension name and the file header information both point to the same coding standard, the unpacking is performed according to the packing mode indicated by the file extension name or the file header information, which is the same.
Step 404: controlling the decapsulation sub-assembly to decapsulate according to the encapsulation mode indicated by the file header information;
The step is based on the result of the judgment in step 402 that the file extension name and the file header information are not matched, and aims to perform decapsulation by the execution body control decapsulation sub-component according to the encapsulation mode indicated by the file header information, which is a decision made in consideration of the fact that the file extension name can be easily modified and the possibility of modifying the file header information is low.
Step 405: and in response to failure after the decapsulation is carried out according to the encapsulation mode indicated by the file header information, controlling the decapsulation sub-component to randomly try other unexperienced decapsulation modes until the decapsulation is successful.
Based on step 404, this step aims at solving the problem that the unpacking is failed after the unpacking is performed according to the packing mode indicated by the file header information, that is, the information indicating the packing mode is also inaccurate in the record in the file header, so that the "most stupid" unpacking can be performed only by using the mode of trying, that is, the unpacking subassembly is controlled to randomly try other unpacking modes which are not tested until the unpacking is successful. Also, in the case of supporting the multi-threading technology, the determination efficiency can be accelerated in a manner of running a plurality of try threads for attempting different decapsulation manners in parallel.
It should be noted that, step 405 in this embodiment provides a feasible solution only for the case that the unpacking is failed in the packing manner indicated by the header information, which does not mean that there is only such a solution, and according to the actual situation, it may also attempt to find other parameters that also point to the packing manner, or feed back the unpacked message to the uploader of the target video, in order to receive the coding standard adopted by the uploader to generate the target file, and so on. Thus, step 405 may not be included in other embodiments.
On the basis of any embodiment, aiming at the branch of the web page player supporting the actual coding standard, the web page assembly component can be controlled to send the target video to the web page player for playing so as to complete the normal playing of the target video by the capability of the web page player. Meanwhile, in order to avoid that the webpage player can complete normal unpacking, decoding and rendering of the target video after determining the webpage player, the webpage player can also attach the determined actual coding standard and unpacking mode supported by the webpage player when the webpage assembly component sends the target video to the webpage player, so that the webpage player can accelerate the subsequent processing speed under the condition of knowing the information.
For deepening understanding, the disclosure further provides a specific implementation scheme in combination with a specific application scenario:
1) A user selects a video file presented on a video-on-demand website through a browser, so that a playing request of the video file to be played is generated to a webpage side JS processing frame;
2) The JS processing framework issues the task of analyzing the video file to WASM components;
3) The decapsulator under WASM module firstly decapsulates according to the suffix-AVI of the video file, but finds that the data to be decoded obtained after the decapsulation is wrong, so that the relevant field information pointing to the FLV encapsulation mode is found after the file header information is accessed, and finally the decapsulation is successfully completed according to the AVI mode to obtain the data to be decoded;
4) The decapsulator sends the data to be decoded to a decoder under WASM components;
5) The decoder judges that the data to be decoded adopts the coding standard of H.265, but the current webpage player does not support the coding standard, so the decoder sends the data to be decoded to a transcoder under a WASM component;
6) The transcoder transcodes the data to be decoded encoded according to the encoding standard of H.265 into transcoded data encoded according to the supported H.264 encoding standard;
7) The transcoder then sends the transcoded data and the standard of H.264 adopted after transcoding to a decoder;
8) The decoder decodes the transcoded data according to the received H.264 standard information to obtain data to be rendered;
9) And the decoder sends the data to be rendered to a renderer under the WASM component to complete rendering, and finally the renderer outputs the video file after rendering to an interface prepared by the webpage player.
With further reference to fig. 5, as an implementation of the method shown in the foregoing figures, the present disclosure provides an embodiment of a web video playing apparatus, where an embodiment of the apparatus corresponds to the embodiment of the method shown in fig. 2, and the apparatus may be specifically applied to various electronic devices.
