step S4: and decoding and playing the audio and video data to be played according to the detection result.
In the step S1, the first terminal playing device adds multiple standard types of preset codec formats, and since most terminal playing devices have limited supportable codec formats, most terminal playing devices usually have one or two supportable codec formats, and if the codec formats of the audio/video data to be played uploaded by the client are of two or more types, the first terminal playing device needs to transcode the audio/video data to be played to realize normal playing of the audio/video data.
In the embodiment, the preset encoding and decoding formats of multiple standard types are added into the first terminal playing device, so that the situation that the audio and video data to be played are in multiple encoding and decoding formats is prevented as much as possible, and at this moment, the first terminal playing device needs transcoding to cope with the situation, therefore, the first terminal playing device can avoid that the first terminal playing device transcodes the audio and video data to be played in the encoding and decoding formats which are not matched with the first terminal playing device by adding the preset encoding and decoding formats of multiple standard types in advance, so that the audio and video processing speed is increased, and the playing delay is reduced.
Specifically, the preset codec formats of the multiple standard types may be an H264 video codec format type and/or an H263 video codec format type and/or an H261 video codec format type and/or an H265 video codec format type and/or an MPEG-1 video codec format type and/or an mp3 audio codec format type and/or an aac audio codec format type and/or a g.711 audio codec format type.
In the step S2, the audio/video data to be played may be sent to the first terminal playing device in this embodiment through the audio/video collecting device, where the audio/video data to be played is used for the audio/video data to be played and watched.
In the step S3, detecting whether the initial codec format of the audio/video data to be played meets the requirement of the preset codec format, specifically, the first terminal playing device may start a detection program to detect the decoding playing standard of the audio/video data to be played; for example: when the type of the encoding and decoding of the initial encoding and decoding format is A, B, C, the type of the preset encoding and decoding format comprises A, B, C, D types, and the initial encoding and decoding format meets the requirements of the preset encoding and decoding format; for example: when the type of the codec of the initial codec format is A, B, C, D, E, the types of the preset codec format include A, B, C, D types, and the initial codec format does not meet the requirements of the codec format, according to the existing method, A, B, C, D, E needs to be transcoded into a, B, C, or D at the same time.
In this embodiment, the processing method for playing the audio/video data in the present invention is equivalent to lossless transparent transmission processing, and does not need to perform transcoding operations back and forth on all initial codec formats of the uploaded audio/video data to be played, specifically, by adding a plurality of standard types of preset codec formats in advance, it is further detected whether the initial codec formats of the audio/video data to be played meet the requirements of the preset codec formats, and under the condition that the initial codec formats of the audio/video data to be played meet the requirements of the preset codec formats, decoding playing is quickly achieved, transcoding switching back and forth is not needed, delay in audio/video playing can be reduced, CPU processing speed of the first terminal playing device is increased, and packet loss of the audio/video data to be played can be reduced.

In the above step S12, the initial codec format attribute includes a codec format type, an audio/video bitrate, an audio/video frame rate, an audio/video resolution, and the like, for example: the codec format type may be an H264 video codec format type and/or an H263 video codec format type and/or an H261 video codec format type and/or an H265 video codec format type and/or an MPEG-1 video codec format type and/or an mp3 audio codec format type and/or an aac audio codec format type and/or a g.711 audio codec format type.
Step S13: detecting whether the attribute of the initial codec format belongs to the attribute contained in the preset codec format, for example: the initial codec format type in the initial codec format attributes is H264 video codec format type, mp3 audio codec format type, and rate is 600kbps, and resolution is 1920 × 1080, and the codec format H264 video codec format type and/or H263 video codec format type and/or H261 video codec format type and/or H265 video codec format type and/or MPEG-1 video codec format type and/or mp3 audio codec format type and/or aac audio codec format type and/or g.711 audio codec format type, etc. are supported by the initial codec format attributes, and the rate supports 600kbps, 800kbps, 900kbps, resolution supports 1920 × 1080, 1080 × 720, 720 × 576, etc. therefore, the codec format attributes are among the attributes included in the preset codec format, otherwise, the attribute of the initial coding and decoding format is not in the attribute contained in the preset coding and decoding format; for example: the attribute contained in the preset encoding and decoding format comprises A, B, C, D, and the encoding and decoding format of the audio and video to be played is A, B, C, D, E; at this time, E does not belong to the attribute included in the preset codec format.

In the above steps S41 to S42, by adding a plurality of standard types of preset codec formats in advance, it is further detected whether the initial codec format of the audio/video data to be played meets the requirement of the preset codec format, and under the condition that the initial codec format of the audio/video data to be played meets the requirement of the preset codec format, decoding playing is quickly achieved without transcoding switching back and forth, so that delay of audio/video playing can be reduced, the CPU processing speed of the first terminal playing device can be increased, and the packet loss phenomenon of the audio/video data to be played can be reduced.
Example 4
In a specific implementation manner of this embodiment, when the initial codec format of the audio/video data to be played conforms to the preset codec format, the step S41 of decoding and playing the audio/video data to be played includes the following steps in an execution process:

Step S114: the audio and video data to be played after the virus information is deleted is directly decoded and played or the decoded audio and video data to be played is sent to the second terminal playing device to be played, the audio and video data to be played can be directly decoded and played locally through the first terminal playing device, and in order to achieve communication among the plurality of terminal playing devices, the audio and video data to be played after the first terminal playing device is decoded can be issued to the second terminal playing device to be played, so that the playing efficiency can be improved, and the playing delay is reduced.
Example 5

Step S212: according to the identification result, whether the audio and video data to be played have packet loss data or not is determined, and the phenomenon of packet loss data can cause the integrity of the audio and video data to be played, influence the audio and video playing effect and further influence the viewing interest of users.
Step S213: when the audio and video data to be played has packet loss data, the audio and video data to be played is repaired, the normal and complete audio and video data can be compared with the audio and video data to be played, and the packet loss data is supplemented and repaired.
