In this embodiment, after receiving the work request, the transcoding server may send a work response to the control server, where the work response may be heartbeat packet data, and may be integrated information data of the transcoding server, such as address information, hardware information, status information, and the like.
Specifically, after each transcoding server responds to the work request, a work response may be generated according to the work request, and the work response is sent to the control server.

And step 203, sending the video stream data to a plurality of transcoding servers according to the work response.

For example, when the work response is information data, the information data may include address information, hardware information, status information, and the like of the transcoding server. The control server can judge whether the transcoding server works or not, whether transcoding work can be completed or not, whether connection is completed or whether the transcoding server is in transcoding or on line or not and the like according to the address information, the hardware information and the state information, so that the control server can determine whether the transcoding server can receive video stream data or not to perform transcoding operation according to the information.
In practical operation, after the control server determines the transcoding servers capable of performing transcoding operation, the video stream data can be sent to the transcoding servers, and the transcoding servers perform transcoding operation on the video stream data. The control server sends the video stream data to different transcoding servers for transcoding, so that video resource allocation can be effectively realized, memory resources are reasonably utilized, and the coding and transcoding efficiency of the video can be effectively improved.
In this embodiment, step 203 may include the following sub-steps:
and a substep 2031 of obtaining a plurality of transcoding addresses corresponding to the plurality of transcoding servers according to the work response.
In this embodiment, the transcoding address may be address information of the transcoding server. Since the control server may be connected to a plurality of transcoding servers, each transcoding server may have a corresponding address information in order to allow the control server to efficiently manage each transcoding server. The address information may be address information compiled by a user when the control server is connected with the transcoding server, or address information set by the user on the transcoding server through the control server, or address information allocated to each transcoding server by the control server.
Specifically, since the number of the controlled transcoding servers is large, in order to improve the management efficiency, the transcoding servers can be effectively managed by adding the transcoding addresses.
After the transcoding server receives the work request sent by the control server, the transcoding server can respond to the work request, information such as state information, hardware information and address information of the transcoding server is generated into an information packet, then the transcoding server sends the information packet to the control server, and the control server can take the information packet as a work response. Then, after the information packet is obtained, the control server may obtain a transcoding address corresponding to the transcoding server from the information packet. .
In practical operation, when the transcoding server is idle or in a standby state, the transcoding server may respond to the work request, and when the transcoding server is in a working state, the transcoding server may not respond to the work request during encoding and decoding.
Sub-step 2032 of determining one or more target addresses identical to the pre-stored addresses from the plurality of transcoded addresses.
In this embodiment, since the transcoding server is in idle or standby, it will respond to the work request and return a work response. When the control server receives the work response sent by the transcoding server, it may be determined that the transcoding server sending the work response is currently in an idle state, and may be used to encode and decode video stream data. Also in this embodiment, since the transcoding address of the transcoding server may be added to the transcoding server by the control server for the user, or distributed to a different transcoding server by the control server. After addition or allocation, the control server may record different transcoding addresses. The control server can determine whether the transcoding server corresponding to the transcoding address establishes connection with the control server and can receive video stream data to perform transcoding or encoding and decoding operations by judging the transcoding address. When the transcoding address sent by the transcoding server is the same as the address stored in the control server, it may be determined that the transcoding address is a target address, the transcoding server corresponding to the target address is a target transcoding server, and the target transcoding server is in an idle or standby state, and may perform transcoding operations.
For example, when the obtained transcoding address is 1.11.11.1 and 1.11.11.1 is included in the stored addresses, the address may be determined to be the target address; if 1.11.11.1 is not included in the stored plurality of addresses, it may be determined that the address is not a target address.
In this embodiment, the control server may determine, through the transcoding address, a transcoding server capable of performing transcoding or encoding and decoding operations, so that the idle or standby transcoding server may be used to work, resources may be more reasonably allocated, and resource utilization may be effectively improved.
Substep 2033, sending the video stream data to the transcoding server corresponding to the target address.
In this embodiment, after the corresponding transcoding server in the standby or idle state is determined by the transcoding address, the control server may send the video stream data to the transcoding server in the standby or idle state, and the transcoding server in the standby or idle state transcodes or encodes and decodes the video stream data.
In actual operation, if the transcoding server in a standby or idle state is single, the video stream data can be sent to the transcoding server; if a plurality of transcoding servers are in standby or idle states, in order to improve the efficiency of encoding, decoding and transcoding, the video stream data can be divided into a plurality of video stream data segments, the plurality of video stream data segments are respectively sent to the plurality of transcoding servers, and the plurality of different transcoding servers perform transcoding operation on the video stream data segments, so that the transcoding efficiency can be further improved, and the utilization rate of resources can be improved.
In this embodiment, the sub-step 2033 may comprise the following sub-steps:
substep 20331, counting the number of addresses of the target address.
In this embodiment, after the control server obtains the target addresses, the number of the target addresses may be counted, and the number of the transcoding servers in the current standby or idle state may be determined by counting the number of the target addresses, so as to determine whether to split the video stream data, and further improve the utilization rate of the resources.
Sub-step 20332 of determining whether the number of addresses is greater than or equal to two.
In this embodiment, when the number of addresses is greater than or equal to two, it may be stated that the number of transcoding servers in a waiting or idle state is greater than or equal to two, and in order to improve transcoding efficiency, video stream data may be appropriately divided into video stream data segments equal to the number of transcoding servers, different video stream data segments may be sent to different transcoding servers, and the different transcoding servers transcode the video stream data segments, so that transcoding efficiency may be improved, and resource utilization may also be improved.
When the number of addresses is less than two, it can be said that the number of transcoding servers in a standby or idle state is one, and only one transcoding server is in an idle state, the video stream data can be directly sent to the transcoding server, and the transcoding server performs transcoding operation.
Sub-step 20333, if the number of addresses is greater than or equal to two, segmenting the video stream data into video blocks with corresponding number according to the number of addresses.
In this embodiment, when the number of addresses is greater than two, the control server may slice the video stream data into video blocks of the same number as the addresses. For example, if the number of addresses is five and is greater than two, the control server may divide the video stream data into 5 video blocks, and may send the 5 video blocks to 5 different transcoding servers, respectively, where the transcoding servers perform corresponding transcoding operations.
When splitting, the video stream data may be split into a plurality of video blocks with the same content capacity, or into a plurality of video blocks with different memory capacities. For example, the video stream data is 1000k, and is required to be divided into 4 video blocks, may be divided into 4 video blocks of 250k, or may be divided into video blocks of 100k, 200k, 300k, and 400k, respectively.
Sub-step 20334, performing identification processing on the corresponding number of video block blocks to generate an identification video block.
In this embodiment, the identification process may encode identification or address identification or connection identification, etc. After the video blocks are cut into a plurality of video blocks, in order to splice the cut video blocks into a complete video stream again, each cut video block piece can be identified, the control server can splice the video blocks again according to the identification, and finally, a complete video stream can be generated.
In a specific operation, the control server may add identification data, for example, 111 for the first, 222 for the second, 333 for the third, etc., to the front of the video stream of each sliced video block.
And a substep 20335 of sending the marked video block to a transcoding server corresponding to the target address for transcoding processing.
