step S210, receiving audio and video data to be transcoded, wherein the audio and video data to be transcoded carries a matching identifier, and matching the audio data with corresponding video data according to the matching identifier.
Specifically, the audio/video data to be transcoded can be received from the audio/video background server, the audio/video data to be transcoded can be contained in the transcoding request, and the matching identifier is used for identifying the source of the audio/video data, as if the audio data and the video data of one program carry the same matching identifier, the audio data and the video data of the same chat room carry the same matching identifier. And matching the audio data and the video data with the same matching identification so as to be conveniently transmitted to the same transcoding server.
And step S220, sending the audio data and the video data which are matched with each other to the same transcoding server so that the transcoding server performs confluence and transcoding on the audio data and the video data which are matched with each other to generate a target transcoding file.
Specifically, the distribution server may select an appropriate target transcoding server according to working state parameters of the transcoding server, where the working state parameters include a process idle number, server hardware configuration, and the like. The audio data and the video data which are matched with each other can be sent to the same process or different processes of the same transcoding server. The audio data corresponding to the video data can be quickly found out by sending the audio data to the same transcoding server, out-of-order data packets can be sequenced in the same server, data interaction among a plurality of servers is not needed, and the speed of converging the audio data and the video data is increased. After the target transcoding server and the process are determined, corresponding transcoding information can be recorded, which is used for determining specific information corresponding to a sender of the audio data and the video data which are matched with each other, such as an IP (Internet Protocol) address of the target transcoding server, a port of the target transcoding server, a process number of the target transcoding server, and the like. The transcoding server merges the audio data and the VIDEO data which are matched with each other, and then performs transcoding, for example, the audio data packet and the VIDEO data packet are combined and converted into a data packet in a flv (FLASH VIDEO, streaming media format) format.
In the embodiment, through receiving audio and video data to be transcoded, the audio and video data to be transcoded carries the matching identification, the audio data and the corresponding video data are matched according to the matching identification, the audio data and the video data which are matched with each other are sent to the same transcoding server, so that the transcoding server merges the audio data and the video data which are matched with each other and transcodes the audio data and the video data to generate the target transcoding file, the audio data and the video data which are matched with each other are sent to the same transcoding server, the audio data corresponding to the video data can be found quickly, data interaction does not need to be carried out among a plurality of servers, the speed of merging the audio data and the video data is accelerated, and the transcoding efficiency of the video.
In one embodiment, as shown in fig. 4, step S220 includes:
and step S221, acquiring working state parameters of the transcoding server, selecting a target transcoding server according to the working state parameters, and sending the audio data and the video data which are matched with each other to the same process of the target transcoding server.
Specifically, the idle ratio of the transcoding server is judged according to the working state parameters of the transcoding server, and the transcoding server with the large idle ratio is used as the selected target transcoding server. If the working state parameters are the number of the unused processes and the total number of the processes to be distributed, calculating the proportion of the number of the unused processes and the total number of the processes to be distributed corresponding to different transcoding servers to obtain the idle proportion corresponding to different transcoding servers, and taking the transcoding server with the large idle proportion as the selected target transcoding server. The operating state parameters may also include hardware configuration, memory remaining, etc. And after the target transcoding server is determined, acquiring an idle process in the target transcoding server, and sending the audio data and the video data which are matched with each other to the same process of the target transcoding server. The data packets are more conveniently sorted and processed in the same process, and the communication among the processes is not needed, so that the transcoding efficiency is further improved.
Step S222, transcoding information corresponding to the target transcoding server is obtained, and the transcoding information is sent to the cloud server to be stored.
Specifically, the transcoding information is used to determine an object for actually transcoding the audio data and the video data that are matched with each other, such as an IP address of a target transcoding server, a port of the target transcoding server, a process number of the target transcoding server, and the like. The transcoding information can be stored corresponding to the matching identification of the audio data and the video data, so that different matching identifications correspond to different transcoding information, when the audio data and the video data need to be transcoded next time, the corresponding transcoding information can be obtained according to the matching identification carried by the audio data and the video data, and a target transcoding server for transcoding is determined according to the transcoding information. The transcoding information is sent to the cloud server to be stored, so that a plurality of different distribution servers can conveniently and quickly obtain the transcoding information from the cloud server when the transcoding data is distributed next time. And the servers are clearly separated from one another, and the working efficiency is high.
In one embodiment, as shown in fig. 5, step S220 includes:
step S223, obtaining the transcoding information, where the transcoding information includes the matching identifier.
Specifically, the transcoding information includes matching identifiers so as to establish a correspondence between the actual transcoding object and the audio and video source.
And step S224, searching whether the matching identification carried by the audio and video data to be transcoded exists in the transcoding information, if so, entering step S225, and otherwise, entering step S226.
Specifically, if the matching identifier carried by the audio and video data to be transcoded exists in the transcoding information, it is indicated that the audio and video data with the same source as the audio and video data to be transcoded is transcoded, and a first transcoding server and a first process used for transcoding before the audio and video data with the same source are obtained from the transcoding information. Therefore, the method can enter step S225, and audio and video data to be transcoded are sent to the first transcoding server, so that the audio and video data with the same source are transcoded by the same transcoding server, and operations such as sequencing of data packets are facilitated. If the matching identification carried by the audio and video data to be transcoded does not exist in the transcoding information, the audio and video data to be transcoded is sent from a new source, and a new transcoding server can be determined to transcode according to the current working state of the transcoding server.
Step S225, obtaining a first transcoding server corresponding to the matching identifier, and sending the audio data and the video data that are matched to each other to the first transcoding server.
Specifically, the audio and video data with the same matching identification are sent to the same transcoding server, if the audio and video data are transcoded intermittently due to network errors, it is guaranteed that audio and video data packets distributed from the same source and audio and video data packets distributed before can reach the same transcoding server, and the audio and video data sent by different users in sequence like the same video call room number can reach the same transcoding server for transcoding. And sending the audio data and the video data which are matched with each other to the same target process of the same transcoding server according to the process number of the target transcoding server in the transcoding information.
Step S226, the process proceeds to the step of obtaining the operating state parameters of the transcoding server.
In this embodiment, the same audio/video stream with the matching identifier is sent to the same transcoding machine or the same process of the same transcoding server by querying the transcoding information.
In one embodiment, as shown, after step S220, the method further includes: and if no response data packet returned by the transcoding server according to the audio data and the video data which are matched with each other is received, modifying the original target transcoding server in the transcoding information into a second transcoding server, and sending the audio data and the video data which are matched with each other to the second transcoding server next time, or modifying the original target process in the transcoding information into a second process, and sending the audio data and the video data which are matched with each other to the second process of the original target transcoding server next time.
Specifically, each time the transcoding server receives audio data and video data which are matched with each other, if transcoding is successful, a corresponding response data packet is returned, and the response data packet carries a matching identifier for identifying which source data packet is successfully transcoded. If no response data packet returned by the transcoding server according to the audio data and the video data which are matched with each other is received, the transcoding server which performs transcoding or the target of the transcoding server goes wrong, and the transcoding server or the process in the transcoding server needs to be replaced. In one embodiment, the number of audio and video data to be transcoded, which do not receive a response data packet, is counted, if the number exceeds a preset threshold value, an original target transcoding server in transcoding information is modified into a second transcoding server, audio data and video data which are matched with each other are sent to the second transcoding server next time, or an original target process in transcoding information is modified into a second process, and audio data and video data which are matched with each other are sent to the second process of the original target transcoding server next time. If 4000 continuous packets do not return response data packets after finding that the audio/video data packets to be transcoded corresponding to a certain matching identifier are distributed to the original target transcoding server or the original target process distributed to the original target transcoding server, the original target transcoding server or the original target process is considered to have problems, and a new transcoding server or process can be switched. And the information is modified in the transcoding information to ensure that the information is synchronized at each distribution server. When the original target transcoding server or the original target process is found to have problems, warning information can be sent to a mailbox of a user or displayed on a terminal, so that the reminding effect is achieved. In this embodiment, when it is detected that a process of the transcoding server or the transcoding server has an error by whether the response packet is received, the process can be self-repaired, and another transcoding server or process is used for transcoding.
In one embodiment, as shown in fig. 6, there is provided a method of transcoding data processing, including:

And step S330, the transcoding server performs confluence and transcoding on the audio data and the video data which are matched with each other to generate a target transcoding file.

Step S322, the distribution server obtains the transcoding information corresponding to the target transcoding server, and sends the transcoding information to the cloud server for storage.
Specifically, the transcoding information is used to determine an object for actually transcoding the audio data and the video data that are matched with each other, such as an IP address of a target transcoding server, a port of the target transcoding server, a process number of the target transcoding server, and the like. The transcoding information can be stored corresponding to the matching identification of the audio data and the video data, so that different matching identifications correspond to different transcoding information, when the audio data and the video data need to be transcoded next time, the corresponding transcoding information can be obtained according to the matching identification carried by the audio data and the video data, and a target transcoding server for transcoding is determined according to the transcoding information. The distribution server sends the transcoding information to the cloud server for storage, and a plurality of different distribution servers can conveniently and quickly obtain the transcoding information from the cloud server when the transcoding data is distributed next time. And the servers are clearly separated from one another, and the working efficiency is high.
In one embodiment, as shown in fig. 8, step S320 includes:
step S323, the distribution server obtains the transcoding information, where the transcoding information includes the matching identifier.
Specifically, the transcoding information includes matching identifiers so as to establish a correspondence between the actual transcoding object and the audio and video source.
Step S324, the distribution server searches whether a matching identifier carried by the audio and video data to be transcoded exists in the transcoding information, if yes, step S325 is carried out, and if not, step S326 is carried out.
Specifically, if the matching identifier carried by the audio and video data to be transcoded exists in the transcoding information, it is indicated that the audio and video data with the same source as the audio and video data to be transcoded is transcoded, and a first transcoding server and a first process used for transcoding before the audio and video data with the same source are obtained from the transcoding information. Therefore, the method can enter step S225, and audio and video data to be transcoded are sent to the first transcoding server, so that the audio and video data with the same source are transcoded by the same transcoding server, and operations such as sequencing of data packets are facilitated. If the matching identification carried by the audio and video data to be transcoded does not exist in the transcoding information, the audio and video data to be transcoded is sent from a new source, and a new transcoding server can be determined to transcode according to the current working state of the transcoding server.
Step S325, obtain the first transcoding server corresponding to the matching identifier, and the distribution server sends the audio data and the video data that are matched to each other to the first transcoding server.
Specifically, the audio and video data with the same matching identification are sent to the same transcoding server, if the audio and video data are transcoded intermittently due to network errors, it is guaranteed that audio and video data packets distributed from the same source and audio and video data packets distributed before can reach the same transcoding server, and the audio and video data sent by different users in sequence like the same video call room number can reach the same transcoding server for transcoding. And sending the audio data and the video data which are matched with each other to the same target process of the same transcoding server according to the process number of the target transcoding server in the transcoding information.
In step S326, the distribution server obtains the operating state parameters of the transcoding server.
In this embodiment, the distribution server sends the same audio/video stream with the matching identifier to the same transcoding machine or the same process of the same transcoding server by querying the transcoding information.
In one embodiment, after step S330, the method further includes: and the transcoding server generates a response data packet of the target transcoding file and sends the response data packet to the distribution server.
Specifically, each time the transcoding server receives audio data and video data which are matched with each other, if transcoding is successful, a corresponding response data packet is returned to the distribution server, and the response data packet carries a matching identifier for identifying which source data packet is successfully transcoded.
After the step of sending the audio data and the video data which are matched with each other to the same transcoding server by the distribution server, the method further comprises the following steps: and if the distribution server does not receive the response data packet, modifying the original target transcoding server in the transcoding information into a second transcoding server, and sending the audio data and the video data which are matched with each other to the second transcoding server next time, or modifying the original target process in the transcoding information into a second process by the distribution server, and sending the audio data and the video data which are matched with each other to the second process of the original target transcoding server next time.
Specifically, if a response data packet returned by the transcoding server according to the audio data and the video data which are matched with each other is not received, it is indicated that a problem occurs in the transcoding server for transcoding or the target of the transcoding server, and the transcoding server needs to be replaced or a process in the transcoding server needs to be replaced. In one embodiment, the number of audio and video data to be transcoded, which do not receive a response data packet, is counted, if the number exceeds a preset threshold value, an original target transcoding server in transcoding information is modified into a second transcoding server, audio data and video data which are matched with each other are sent to the second transcoding server next time, or an original target process in transcoding information is modified into a second process, and audio data and video data which are matched with each other are sent to the second process of the original target transcoding server next time. If 4000 continuous packets do not return response data packets after finding that the audio/video data packets to be transcoded corresponding to a certain matching identifier are distributed to the original target transcoding server or the original target process distributed to the original target transcoding server, the original target transcoding server or the original target process is considered to have problems, and a new transcoding server or process can be switched. And the information is modified in the transcoding information to ensure that the information is synchronized at each distribution server. When the original target transcoding server or the original target process is found to have problems, warning information can be sent to a mailbox of a user or displayed on a terminal, so that the reminding effect is achieved. In this embodiment, when it is detected that a process of the transcoding server or the transcoding server has an error by whether the response packet is received, the process can be self-repaired, and another transcoding server or process is used for transcoding.
In one embodiment, after step S340, the method further includes: and the transcoding server sends transcoding state information to the state server, and the state server receives a video searching request and searches whether a corresponding video transcoding file with successful transcoding exists according to the transcoding state information.
Specifically, the state server stores transcoding state information corresponding to each video, and the transcoding state is divided into successful transcoding and unsuccessful transcoding. And when the video needs to be played next time, the state server receives a video searching request, searches whether a corresponding video transcoding file with successful transcoding exists according to the transcoding state information, and if so, the corresponding video transcoding file can be directly sent to the terminal for playing without secondary transcoding. If the user needs to watch the video, the Content Delivery Network (CDN) can be used for returning the source, and the CDN queries a corresponding video transcoding file with successful transcoding through a state server, acquires a flv video stream from the transcoding server, and issues the flv video stream to the user.
