The video playing method provided by the embodiment of the disclosure can transcode the video type which cannot be played originally into the video type which can be played. In the embodiment of the present disclosure, the detailed description of the scheme is performed by taking the video playing of the browser as an example, the corresponding application program is the browser, and other situations are similar to the above and are not described again. The browser application has a video playing function. The browser application program is provided with an interface for hardware decoding and decapsulating the video data, and the interface acquires the transcoded video data by accessing the website, and decodes and decapsulates the transcoded video data to obtain the video data which can be played by the browser.

And step 304, sending the transcoded first video to the terminal.
Fig. 4 is a flowchart illustrating interaction between a server and a terminal in a video playing method according to an embodiment of the present disclosure.
Referring to fig. 4, the process includes:
the method comprises the steps of obtaining a first video type of a first video, and determining that the video type supported by the browser does not comprise the first video type according to the video type supported by the browser.
In implementation, a user clicks a skip link of a first video to enter a video playing interface, a terminal can load the first video and obtain metadata of the first video, the metadata is analyzed to obtain a video format of the first video, the video format of the first video can also be obtained by accessing a resource server stored in the first video, the video type can be obtained by checking the video type which can be decoded by a hardware decoding function and stored in the terminal, after the terminal obtains the first video type, the first video type is compared with the video type which can be decoded by the hardware decoding function, and the comparison result shows that the video type which can be decoded by the hardware decoding function does not include the first video type.
And in the second mode, the failure of the browser to play the first video of the first video type is detected.
In implementation, a user clicks a skip link of a first video to enter a video playing interface, a terminal accesses a resource server stored in the first video to load the first video, the first video is unpackaged by a hardware unpacking function after the first video is loaded, the first video is decoded by a hardware decoding function, when the first video is unpacked or decoded, a processing unit of the hardware decoding and unpacking function detects that the video type which can be decoded and unpacked by the hardware decoding and unpacking function does not include the first video type, and the hardware decoding function fails to decode the first video.
Step 402, the terminal sends a transcoding instruction to the server.
In order to reduce the load of the server, the relay server may be a server group consisting of a first server and a second server, the first server is used for performing interaction with other devices and some basic processing functions, the second server is used for performing transcoding of the video, and a data connection is established between the two servers.
In implementation, when detecting that the hardware decoding function and/or the decapsulation function of the terminal cannot decode and/or decapsulate the first video of the first video type, the terminal adds the address of the first video (the address of the first video may be a URL) and the video type supported by the local hardware decoding function and/or the decapsulation function to the transcoding instruction, and sends the transcoding instruction to the transit server.
Step 403, after receiving the transcoding instruction sent by the terminal, the server acquires the first video based on the address of the first video.
Wherein the first video is stored in the resource server and the address of the first video is the address in the resource server.
In implementation, the transit service receives the transcoding instruction sent by the terminal, the first server receives the transcoding instruction and sends the address of the first video to the second server, and the second server accesses the address of the first video and loads the first video of the first video type.
In step 404, the server transcodes the first video from the first video type to the second video type and sends the transcoded first video to the terminal.
The video types supported by the browser comprise the second video type, the second video type is a video type supported by a hardware decoding function and/or a decapsulation function of the terminal, and the loading of the first video and the transcoding of the first video can be performed simultaneously.
In implementation, a first server performs transcoding configuration according to a downloaded first video, that is, a transfer server sorts video types supported by a hardware decoding function and/or a decapsulation function of a terminal according to stored video type priorities, selects a video type with the highest priority as a second video type, the first server sends an address and transcoding configuration to a second server, the second server obtains a video stream of the first video based on the address, transcodes the first video from the first video type to the second video type in the process of receiving the first video, allocates an address of a resource server for the transcoded first video, adds an identifier of the transcoded first video into the address, and sends the address of the resource server added with the identifier to the terminal by the second server. The address may be a URL (Uniform Resource Locator).
And 405, the terminal receives and plays the transcoded first video sent by the server.
The type of the transcoded first video is a second video type, the second video type is a video type supported by a local hardware decoding function and/or a decapsulation function, and the resource server may be a content distribution network.
In implementation, after receiving an address sent by a first server, as shown in fig. 5, a terminal sends an HTTP (HyperText Transfer Protocol) request to a content distribution network based on the address, that is, the terminal accesses the address, after receiving the HTTP request, the content distribution network extracts an identifier in the address, where the identifier may correspond to an output address of a first video of a transcoded first video in a second server, and sends the identifier in the request for loading data to the first server, where the first server sends the request for loading data with the identifier to the second server through a data connection with the second server, and the second server obtains the transcoded first video according to the output address of the first video corresponding to the identifier access identifier. And after the acquisition is completed, the second server sends the transcoded first video to the address of the content distribution network. And the terminal is always in a state of accessing the address, and when the address receives the transcoded first video, the terminal also loads the first video and decodes and plays the first video.
After receiving the fast forward and fast backward commands, an interaction flow between the transit server and the terminal may be as shown in fig. 6, where the flow includes:
The playing time point in the first video is the playing time point of each key frame in the first video, the data position in the first video is the position of each key frame in the first video in the video data, and the corresponding relation is the corresponding relation between the playing time point of each key frame and the position of each key frame in the video data.
In implementation, the first server accesses the address of the first video, may obtain metadata of the first video and analyze the metadata to obtain a corresponding relationship between the play time point and the data position of the key frame in the first video, or may directly obtain the corresponding relationship between the play time point and the data position of the key frame in the first video from the address, and send the corresponding relationship to the terminal after the obtaining is completed.
The playing time adjusting instruction can be a fast forward instruction and a fast backward instruction.
In implementation, a terminal receives and stores a corresponding relation sent by a first server, a user triggers a fast forward and fast backward mechanism, the terminal receives corresponding fast forward and fast backward instructions, the terminal acquires playing time points of the fast forward and fast backward instructions, finds a playing time point of a key frame closest to the playing time point, takes the playing time point of the closest key frame as the playing time point of the fast forward and fast backward instructions, determines a data position, namely a target data bit, corresponding to the playing time point of the key frame according to the corresponding relation, and sends the obtained target data bit to the first server.
Step 603, when the server receives the target data bit sent by the terminal, acquiring a second video of which the first video is located behind the target data bit, transcoding the second video from the first video type to a second video type, and sending the transcoded second video to the terminal.
In implementation, as shown in fig. 7, the terminal is always in the state of accessing the address of the content distribution network, and after the first server receives the target data bits sent by the terminal, the first server sends the target data bit to the second server according to the data connection between the first server and the second server, the second server obtains a second video after the target data bit according to the target data bit, transcoding the second video after the target data bit to obtain the transcoded video data in a live stream form, transmitting the second video to the address by the second server according to the address of the content distribution network stored by the second server, after the second video is received by the address, as the terminal is always in the state of accessing the address, the transcoded second video is also transmitted to the terminal, and after the terminal receives the second video, the terminal unpacks, decodes and plays the second video.
The video type which is not supported by the browser is transcoded into the video type which is supported by the browser, so that when the browser is used for playing the video in a network, more types of videos can be played on the electronic equipment on the basis of ensuring power saving.
