Fig. 3 is a flowchart of a method for playing a multimedia file according to an embodiment of the present invention, where the method may be applied to a terminal, and as shown in fig. 3, the method includes:
step 301: and the terminal compiles the transcoding method through the Web language to obtain the first transcoding file, and stores the first transcoding file in the specified storage space.
In the embodiment of the invention, the terminal receives the media stream transmitted by the server through the application program, and the media stream can be played in the Web interface only by converting the coding format of the media stream through the transcoding file. The transcoding method is used for converting a first media stream transmitted by a server into a second media stream in a second coding format, and the second coding format is a coding format which can be identified by an application program of a terminal.
In this step, the Web language is a language that can be recognized by the Web interface, and the first transcoding file compiled by the Web language can also be recognized by the Web interface. The terminal can be directly written through the Web language, or can be firstly written through the programming language and then translated into the Web language through the translation tool, so that the first transcoding file is obtained.
(I): when the terminal is directly written through the Web language, the terminal compiles the transcoding method through the Web language to obtain the first transcoding file, which may include: the terminal writes a coding method for transcoding the media stream in the first coding format into the media stream in the second coding format through the Web language and a compiler corresponding to the Web language, and packages the written coding method into a first transcoding file.
In the embodiment of the present invention, the Web language may be any language that can be recognized by the application program of the Web interface. For example, the Web language may be WebAssembly language, and the first transcoding file is a file in the wasm format.
(II): when the terminal is written by the programming language, the terminal compiles the transcoding method by the Web language to obtain the first transcoding file may include: the terminal writes a transcoding method through a programming language to obtain a second transcoding file, wherein the second transcoding file is used for transcoding the media stream in the first coding format into the media stream in the second coding format; and the terminal translates the second transcoding file into the first transcoding file of the Web language by specifying a translation tool.
The programming language may be a C language, a C + + language, a Java language, or the like, and the terminal may install a compiler and a translation tool corresponding to the programming language in advance. The terminal can compile a coding method through a compiler corresponding to the programming language, and package the compiled coding method into a second transcoding file. And the terminal acquires a translation tool installed in advance, translates the second transcoding file into the Web language from the programming language through the translation tool, and encapsulates the coding method of the Web language into the first transcoding file.
Furthermore, the terminal stores the first transcoding file in a designated storage space, so that the first transcoding file can be directly acquired as required without writing, the time for acquiring the first transcoding file is saved, the transcoding efficiency is improved, and the efficiency for playing the multimedia file is improved.
It should be noted that step 301 may be executed only once, and when the terminal needs to play the multimedia file, the terminal receives the first media stream of the multimedia file through the following step 302, and finally transcodes and plays the first media stream by calling the first transcoding file stored in this step. Or, the terminal may not execute step 301, and when the terminal needs to play the multimedia file, the terminal receives the first media stream of the multimedia file through the following step 302, and then compiles the transcoding method through the Web language by the terminal in step 301 to obtain the first transcoding file, transcodes the first media stream according to the first transcoding file, and finally realize the playing of the multimedia file.
Step 302: when a multimedia file to be played is played, the terminal receives a first media stream in a Web interface of a webpage, wherein the coding format of the first media stream is a first coding format.
In this embodiment of the present invention, the first media stream may be an audio media stream or a video media stream. The terminal can display the Web interface through an application program and display a play button or file identification labels of a plurality of multimedia files in the Web interface. When a user watches a multimedia file in a Web interface through a terminal, the user can trigger a play button or a file identification label of the interested multimedia file, and when the terminal detects that the play button or any file identification label in the Web interface is triggered, the terminal acquires a file identification of the multimedia file to be played and displayed in the Web interface and generates a play instruction; and the terminal receives the first media stream in the Web interface of the webpage according to the playing instruction.
When the first media stream is a media stream which is played by the terminal in history, the terminal can locally cache the first media stream so as to directly obtain the first media stream from local when playing again, so that the first media stream does not need to be transmitted by the server in real time, and data interaction with the server is omitted. Therefore, the step of receiving, by the terminal, the first media stream in the web interface according to the play instruction may be: the terminal detects whether the first media stream exists in the local cache space according to the playing instruction, and when the first media stream exists in the local cache space, the terminal acquires the first media stream in the local storage space; and when the first media stream does not exist in the local cache space, the terminal sends the playing instruction to the server, the playing instruction is used for indicating the server to return the first media stream of the multimedia file to be played, and the terminal receives the first media stream of the server in the Web interface of the webpage according to the playing instruction.
The terminal can obtain the playing instruction based on the file identification tags of the multimedia files to be played, that is, the terminal can display the file identifications of the multiple multimedia files in the Web interface, and when a user triggers a certain file identification tag, the terminal directly starts to play the multimedia files in the playing interface. Or, the terminal may further obtain a play instruction based on a play button, that is, a play button may be set in the play interface, and when the user triggers the play button, the terminal starts playing again.
(I): when the terminal obtains the play instruction based on the play button, the step of obtaining the play instruction by the terminal may be: when the playing button is detected to be triggered, the terminal acquires a file identifier of a multimedia file to be played, which is displayed in the Web interface, and generates a playing instruction according to the file identifier.
In this step, the play button is located in the play interface, and the play interface may be a currently displayed play interface that has not started to be played, that is, the user has not started to watch the multimedia file to be played. Or, the playing interface may also be a currently displayed playing interface that has been played for a certain period of time, that is, after the user pauses to watch, the user continues to watch the multimedia file that has been paused to play.
When the playing interface is a playing interface that has not started playing, the step of the terminal acquiring the playing instruction may be: when a terminal detects that a file identification label of a multimedia file to be played in a Web interface is triggered, acquiring a file identification of the multimedia file to be played, and starting a playing interface of the multimedia file to be played, wherein a playing button is arranged in the playing interface; and when the terminal detects that a play button in the play interface is triggered, generating a play instruction according to the file identifier of the multimedia file to be played.
When the playing interface is a playing interface that has been played for a period of time, the step of the terminal acquiring the playing instruction may be: in a playing interface for pausing playing of the multimedia file, when a terminal detects that a playing button in the playing interface is triggered, a file identifier of a file to be played in the playing interface is acquired, and a playing instruction is generated according to the file identifier.
The file identifier may be set and changed according to a user requirement, which is not specifically limited in the embodiment of the present invention. For example, the file identifier may be a name, a hash value, or the like of the multimedia file to be played.
(II): when the terminal obtains the playing instruction based on the file identification tag corresponding to the multimedia file to be played, the step of obtaining the playing instruction by the terminal may be: when the terminal detects that a file identification label corresponding to a certain multimedia file in the Web interface is triggered, the multimedia file is determined as a multimedia file to be played, a playing instruction is generated according to the file identification corresponding to the multimedia file to be played, and a playing interface of the multimedia file to be played is displayed.
In the embodiment of the present invention, the server may store each multimedia file in the Web interface and the file identifier of the multimedia file in association in advance. When the server receives a playing instruction of the terminal, the server acquires a file identifier of a multimedia file to be played, determines the multimedia file corresponding to the file identifier of the multimedia file to be played from the corresponding relation between the multimedia file and the file identifier according to the file identifier of the multimedia file to be played, acquires a first media stream in the multimedia file, and sends the first media stream to the terminal.
It should be noted that the first media stream is a media stream obtained by a distributor user of a movie and television work acquiring multimedia data in advance through a recording device and encoding the multimedia data according to a first encoding format. The first coding format may not be recognized by the terminal, and when the terminal can recognize the first coding format, the terminal directly plays the first media stream of the first coding format in a Web interface of the application program; when the terminal does not identify the first coding format, the terminal transcodes the first media stream in the first coding format by a transcoding method in a first transcoding file to obtain a second media stream in a second coding format, wherein the first transcoding file is a transcoding file which can be written by a Web language identified by the Web interface, and the second coding format is a coding format which can be identified by the terminal.
In a possible design, the terminal may also transcode the first media stream through the multimedia playing plug-in, that is, the terminal may have the multimedia playing plug-in installed in advance, and when the terminal receives the first media stream, before the terminal performs step 303, the terminal detects whether the multimedia playing plug-in is installed locally; when the multimedia playing plug-in is not installed locally, the terminal executes step 303; when the multimedia playing plug-in is installed locally, the terminal acquires the multimedia playing plug-in, calls a transcoding method in the multimedia playing plug-in, and directly executes step 304. The multimedia plugin can be a flash plugin.
Step 303: and the terminal loads the first transcoding file from the designated storage space and calls the transcoding method in the first transcoding file.
In the embodiment of the invention, when the terminal installs the application program of the Web interface, the application program carries the analysis engine for identifying the Web language, and the terminal can analyze the file of the Web language through the analysis engine. And the terminal directly loads the first transcoding file from the designated storage space, and analyzes the first transcoding file through the analysis engine to obtain the transcoding method in the first transcoding file.
Step 304: and the terminal converts the first media stream into a second media stream in a second coding format by the transcoding method.
In fact, this step is a process of transcoding media streams of different encoding formats. The terminal may implement the transcoding process through the steps of decoding first and then encoding, and this step may be: the terminal decodes the first media stream into a binary third media stream through the transcoding method, and encodes the third media stream into a second media stream in the second encoding format.
The first media stream is in a first encoding format, the second media stream is in a second encoding format, and accordingly, the first encoding format may be any encoding format that can be recognized by the server, and the second encoding format may be any encoding format that can be recognized by an application program where the middle Web interface of the terminal is located. Generally, the media stream sent by the server is in flv format, and the media stream that the terminal can play in the Web interface of the application program is in mp4 format. That is, the first encoding format may be flv format, and the second encoding format may be mp4 format.
In the embodiment of the invention, when the terminal plays the media stream in the Web interface, the bullet screen data of the multimedia file to be played can be displayed, and the bullet screen data can be advertisement information or comment information of the user on the currently played media stream and the like. The server may transmit the multimedia data stream of the multimedia file to be viewed and the barrage data together as a first media stream to the terminal, or the server may transmit the multimedia data stream and the barrage data separately. That is, the first media stream is a multimedia data stream, or the first media stream may also be a multimedia data stream and barrage data.
In a possible design, when the terminal displays the barrage data of the multimedia file to be played, the terminal may transcode the barrage data, and the process of transcoding the barrage data by the terminal may be: the terminal acquires the barrage data of the first media stream; the terminal converts the bullet screen data into bullet screen data flow in the second coding format through the transcoding method; and the terminal inserts the bullet screen data stream into the second media stream.
When the first media stream is a multimedia data stream and a bullet screen data, the step of acquiring the bullet screen data by the terminal may be: the terminal identifies the multimedia data stream in the first media stream, determines the data stream except the multimedia data stream in the first media stream as bullet screen data, and acquires the bullet screen data; or the terminal identifies the bullet screen data in the first media stream according to the data identifier of the bullet screen data and acquires the bullet screen data.
When the first media stream is a multimedia data stream, the step of acquiring the barrage data by the terminal may be: the terminal sends an acquisition instruction to the server, the acquisition instruction is used for indicating the server to return the bullet screen data of the file to be played, the server sends the bullet screen data to the terminal, and the terminal receives the bullet screen data. The obtaining instruction can carry a file identifier of the multimedia file to be played, so that the server can search the bullet screen data corresponding to the multimedia file to be played based on the file identifier.
Further, the bullet screen data is actually a data set of multiple pieces of bullet screen data, for example, the bullet screen data is an information set including multiple pieces of user comment information, when the server sends the bullet screen data to the terminal, the server also sends the display time of the bullet screen data, where the display time is the display time corresponding to each piece of bullet screen data in the process of playing the media stream, and the step of the terminal inserting the bullet screen data stream into the second media stream may be: and the terminal acquires the display time of each piece of bullet screen data in the bullet screen data and inserts a plurality of pieces of bullet screen data into the second media stream according to the display time of each piece of bullet screen data.
Step 305: and the terminal plays the second media stream.
In the embodiment of the present invention, the terminal may play the second media stream in a manner of playing while buffering, or in a manner of playing after buffering.
And when the terminal plays and caches, the terminal plays the currently obtained second media stream in the playing area according to the playing area in the Web interface.
When the terminal caches the second media stream first and then plays the second media stream, that is, the terminal caches the second media stream in the cache space first and stores the file identifier of the multimedia file corresponding to the second media stream and the space identifier of the storage space in an associated manner. The step of playing the second media stream by the terminal may be: the terminal obtains a space identifier corresponding to the file identifier from the corresponding relationship between the file identifier and the space identifier according to the file identifier of the multimedia file corresponding to the second media stream, obtains the multimedia file corresponding to the second media stream from the storage space corresponding to the space identifier, and plays the second media stream in the multimedia file in the playing area according to the playing area in the Web interface. Wherein the space identifier may be a storage path of the storage space.
In fact, the terminal may define the display position of the second media stream in the playing area in advance, and the step of playing the second media stream in the playing area by the terminal according to the playing area in the Web interface may be: and the terminal draws the multimedia data at the corresponding display position in the playing area according to the display position of the multimedia data in the second media stream in the playing area, thereby realizing the playing of the second media stream in the playing area.
Further, the second media stream may further include bullet screen data, when the terminal plays the multimedia data in the second media stream, the terminal may also play the bullet screen data in the second media stream, and the step of playing the bullet screen data in the second media stream by the terminal may be: and the terminal acquires the bullet screen data from the second media stream, acquires a preset bullet screen area corresponding to the bullet screen data, and displays the bullet screen data in the preset bullet screen area.
The preset bullet screen area can be set and changed according to the needs of the user, and the embodiment of the invention is not particularly limited to this. For example, the preset bullet screen area may be an upper half area, a middle area, and the like of the playing area.
