Detailed Description
The technical solutions in the embodiments of the present application will be described clearly and completely below, and it should be understood that the described embodiments are only a part of the embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
For more detailed explanation of the present application, an adaptation method, an adaptation apparatus, a terminal device, and a computer storage medium of an encoder provided in the present application are described in detail below with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 shows a schematic diagram of an application scenario of an adaptation method of an encoder provided in an embodiment of the present application, where the application scenario includes a server 102, an encoding end 104, and a decoding end 106 provided in an embodiment of the present application. Wherein, a network is arranged among the server 102, the encoding end 104 and the decoding end 106. The network is used to provide a medium for communication links between the server 102, the encoding side 104, and the decoding side 106. The network may include various connection types, such as wired, wireless communication links, or fiber optic cables, to name a few. The server 102 can communicate with the encoding side 104 and the decoding side 106 to provide a video data forwarding service for the encoding side 104 or/and the decoding side 106. For example, the encoding end 104 may encode video data (e.g., live video) and send the encoded video data to the server 102, the server 102 may send the encoded video data to the decoding end 106, and the decoding end 106 decodes the encoded video data to obtain video data for a user to view.
In some implementation scenarios, the encoding end 104 and the decoding end 106 may be used interchangeably. In this embodiment, the encoding end 104 and the decoding end 106 are both terminals, and may be various electronic devices with display screens, including but not limited to smart phones, personal digital assistants, tablet computers, personal computers, notebook computers, virtual reality terminal devices, augmented reality terminal devices, and the like. The encoding end 104 and the decoding end 106 may have an internet product or a remote conference product for providing an internet live broadcast service installed therein, where the internet product may be an application APP, a Web page, an applet, and the like used in a computer or a smart phone and related to the internet live broadcast service.
Further, the server 102 may be a server that provides various services. The number of the servers can be one or more, that is, the servers can be implemented by independent servers or a server cluster composed of a plurality of servers. Optionally, the types of the servers may be various, and if in the live broadcast field, the servers may be divided into a plug-in center server, a live broadcast server, a gift server, a collection and reporting server and a configuration server according to their functions, where the collection and reporting server is mainly used to collect and report some information (for example, collect hard coding capability information of each encoder in a coding end and coding operation information of a target encoder); the configuration server is mainly used for generating and storing coding configuration parameters of the available coder, receiving parameter query information of the coding end and sending the corresponding coding configuration parameters to the coding end and the like. In addition, when the anchor users and the audience users are connected, the CDN network server is also included and is mainly used for receiving the media data sent by the anchor users and the audience users, providing the capabilities of buffering, storing and forwarding and distributing the live broadcast content to the audience users.
It should be understood that the number of encoding sides, decoding sides, networks, and servers are merely illustrative. There may be any number of encoding sides, decoding sides, networks, and servers, as desired for an implementation. For example, the server may be a server cluster composed of a plurality of servers. The encoding end and the decoding end interact with a server through a network to receive or send messages and the like. Wherein the server and the encoding end can be used to execute the steps of an adaptation method of an encoder provided in the embodiments of the present application. In addition, when the encoding side performs the adaptation method of the encoder provided in the embodiment of the present application, a part of the steps may be performed at the encoding side, and a part of the steps may be performed at the server, which is not limited herein.
Based on this, the embodiment of the present application provides an adaptation method of an encoder. Referring to fig. 2, fig. 2 is a schematic flowchart illustrating an adaptation method of an encoder according to an embodiment of the present application, which is described by taking the method as an example applied to the encoding end and the server in fig. 1, and includes the following steps:
step S110, any encoding end sends the hard coding capability information of each encoder to the server.
In the present embodiment, the adaptation method of the encoder is described from two execution bodies, i.e., the encoding side and the server. The encoding side is a device for encoding video data. Because the encoding end is usually used for encoding the live video in the network live broadcast, the encoding end can be a live broadcast end in the network live broadcast field; in the case of other scenes (e.g., teleconferencing, etc.), the live end may be the end device that generates the video data. The encoding terminal may be a desktop terminal or a mobile terminal, and the mobile terminal may be at least one of a mobile phone, a tablet computer, a notebook computer, and the like.
Optionally, the encoding end may be configured to run live broadcast software or teleconference software, collect action languages of a main broadcast or a participant, and the like to form video data, and perform operations such as playing on the video data, and display corresponding content on a screen of the encoding end. Further, the encoder may also perform an encoding operation on the video data using the encoder, and send the encoded data to the server. The server may send the received encoded data to a decoder, and the decoder may decode the encoded data, so as to obtain video data to be played for other users and the like to view.
It should be noted that, in a network live broadcast or a teleconference, video data with a relatively large data volume is usually generated, and if the video data is not encoded, the video data is directly transmitted through a network, which requires a relatively long transmission time, and is difficult to meet the requirement for timeliness in a live broadcast or a teleconference. Therefore, video data needs to be compressed by an encoder to reduce transmission time and ensure timeliness of live or remote conferences.
In an alternative embodiment, in one encoding end, multiple encoders may be included, and the types of the encoders may also be various, such as h.262 encoder, h.263 encoder, h.264 encoder, h.265/SCC encoder, av1 encoder, vp8 encoder, vp9 encoder, and so on.
The hard coding capability information refers to the coding capability or performance of the encoder and the supporting situation of the coding end to the encoder. The hard-coding capability information includes, but is not limited to, a type of an encoder, a type of a chip in an encoding end, a system version of a system running in the chip, and a supporting condition of the encoding end or the chip for a certain type of encoder. The supporting situation can be divided into supporting and non-supporting, when supporting, it means that the encoding end or chip can allow a certain type of encoder to work or run, so as to play the encoding role; when not supported, it means that the encoding end or chip does not allow a certain type of encoder to work or operate, and then the type of encoder cannot play an encoding role.
Alternatively, the hard-coded capability information may be stored in a key-value pair storage manner. Wherein, the chip type, the system version and the type of the encoder can be used as Key, and the support case can be used as Value. Value can take 1 or 0, and when 1, the Value represents support; when 0, it means no support. For example, the hard-coding capability information may be < < chip type, system version, type of encoder > > < support case > >. In addition, different encoders correspond to different encoding modes, for example, an h.262 encoding mode is adopted by an h.262 encoder, an h.263 encoding mode is adopted by an h.263 encoder, and the like; therefore, the type of encoder in the hard coding capability information can also be represented in a coding manner.
In addition, in the business field of live broadcast or remote conference and the like, a plurality of coding ends or participants can be provided, so that a plurality of coding ends can be provided; any one of the encoding ends can perform information interaction with the server.
And step S120, the server generates coding configuration parameters of all available coders according to all the hard coding capability information and the service scene information.
Specifically, after receiving the hard coding capability information of each encoder, the server can know the performance of the encoder in any one encoding end, and each type of encoder can perform the encoding operation.
Since different types of encoders have different encoding performance, encoders with different performance are required in different service scenarios (i.e., usage scenarios). Therefore, the performance of the encoder and the application scenario thereof are considered comprehensively when selecting the encoder. Specifically, available encoders are determined from each of the hard-coding capability information and the traffic scenario information, and encoding configuration parameters are generated for the available encoders. The encoding configuration parameters are used for the encoding end to select a suitable encoder (i.e., a target encoder) from a plurality of encoders and start the encoder to perform video encoding.
The service scene information is used to represent the encoding end usage scene, including but not limited to the type of encoder and the live scene information. The live scene information is used to illustrate the live scene, such as super-definition live (e.g. using 720P, 15fps live) and live broadcast. The type of encoder is used to illustrate the encoder required in a certain live scene, for example, super-definition live (e.g. using 720P, 15fps live) requires an H265 encoder, and live broadcast requires a 240x 240H 264 encoder.
Based on the information, the required encoder can be determined according to the service scene information; and then, according to the type and the support clarity of the encoder in the hard coding capability information of the required encoder, whether the required encoder is an available encoder can be determined, and if the required encoder is the available encoder, the corresponding hard coding capability information and the live scene information are used as encoding configuration parameters of the available encoder.
Wherein, an available encoder refers to an encoder on the encoding side that can be used to perform an encoding operation.
Step S130, the encoding end sends the parameter inquiry information to the server.
Step S140, the server sends the corresponding encoding configuration parameters to the encoding end according to the parameter query information.
And S150, the encoding end determines a target encoder according to the corresponding encoding configuration parameters, detects encoding operation information of the target encoder during video encoding, and sends the encoding operation information to a server.
Specifically, when the encoder needs to be started to encode the video data when the encoding end generates the video data, the parameter query information can be sent to the server; the server can inquire the corresponding encoding configuration parameters from the encoding configuration parameters of all available encoders according to the parameter inquiry information and send the encoding configuration parameters to the encoding end. The encoding end can determine a target encoder according to the corresponding encoding configuration parameters, then the target encoder is adopted to encode the video data, the encoding operation information of the program encoder in the encoding process of the target encoder is collected, and the encoding operation information is sent to the server.
The parameter query information is data or information used for querying configuration parameters of the encoder from the server, and includes, but is not limited to, chip information in the encoding end, system version of an operating system in the chip, service scenario information, encoding end identification information (such as ID), and the like.
Specifically, the encoding end acquires chip information, system version, and service scenario information (e.g., id) thereof to form parameter query information. And inquiring in the server according to the parameter inquiry information to hit the coding configuration parameters meeting the conditions. Wherein the chip information may be a chip type.
The encoding operation information is some data or information generated in the operation process of the target encoder, and includes, but is not limited to, encoding resolution, frame rate, code rate, encoding mode, encoder operation exception information, and the like, where the encoding mode may also include a preset encoding mode and an actual encoding mode. The preset encoding mode generally refers to an encoding mode included in the encoding configuration parameters of the target encoder, and the encoding mode may be determined directly according to the type of the encoder, for example, the encoding mode of the H264 encoder is an H264 encoding mode. The actual encoding method is an encoding method adopted by the target encoder when encoding the video, for example, the target encoder is an H265 encoder, the H265 encoding method should be adopted when encoding, and the detected actual encoding method is an H264 encoding method, and in this case, it is described that the target encoder is an H265 encoder and an H264 encoder is actually adopted.
The encoder running exception information includes, but is not limited to, an encoder start exception, an encoder running frame spitting exception, an encoder stop exception, and the like.
And step S160, the server judges whether the target encoder is abnormal or not according to the encoding operation information, and if so, updates the corresponding encoding configuration parameters so that the encoding end updates the target encoder.
The server can judge whether the target is abnormal according to the coding operation information, and if so, the server updates the corresponding coding configuration parameters so that the coding end updates the target coder.
Optionally, the updating of the corresponding encoding configuration parameter may be updating hard-coding capability information of the encoder, i.e. updating < < chip type, system version, type of encoder >, < support case > >, for example, may be updating one or more of chip type, system version, type of encoder, and support case. When the corresponding encoding configuration parameters are updated, the original available encoder at the encoding end may not be used or the original available encoder may be used but the parameters thereof are changed, and then the target encoder may be updated. For example, a certain encoding end uses a target encoder H265 for encoding, and when detecting that the target encoder H265 is abnormal in the encoding process, the encoding configuration parameters (i.e., < < chip type, system version, encoder type >, < support case >) of the target encoder H265 are updated, and the encoding end cannot use the target encoder H265 after updating, that is, the encoding capability of the target encoder H265 is eliminated, and at this time, the encoding end needs to reselect another encoder for encoding video data; alternatively, the target encoder H265 may be used by the encoding end after updating, but the parameters related to the target encoder H265 are changed, and at this time, the target encoder H265 needs to be updated.
In addition, when the encoding end selects other encoders, any encoder can be selected from a plurality of other available encoders for use.
In the adaptation method of the encoder provided by the embodiment of the application, any encoding end sends the hard coding capability information of each encoder to the server; the server generates coding configuration parameters of all available encoders according to all hard coding capability information and service scene information; the encoding end sends parameter query information to the server; the server sends the corresponding coding configuration parameters to the coding end according to the parameter query information; the encoding end determines a target encoder according to corresponding encoding configuration parameters, detects encoding operation information of the target encoder during video encoding, and sends the encoding operation information to a server; and the server judges whether the target encoder is abnormal or not according to the encoding operation information, and if so, the corresponding encoding configuration parameters are used for enabling the encoding end to update the target encoder.
The adaptation method of the encoder generates encoding configuration parameters of available encoders according to the hard encoding capability information and the service scene information of each encoder, then selects a target encoder from a plurality of available encoders according to the configuration parameters, detects the encoding operation condition in the operation process of the target encoder, and updates the target encoder when the encoding operation is abnormal; the method can quickly and accurately select the encoder with good performance according to the encoding capability of the encoder; and when the encoder fails or is abnormal, the encoder is automatically updated without manual intervention, and the operation is very convenient.
In an alternative embodiment, the server may include two types, i.e., a collection reporting server and a configuration server. Specifically, as shown in fig. 3, the encoding end, the collection and reporting server, and the configuration server may communicate with each other. The coding end can be used for detecting the hard coding capacity information of each coder and sending the hard coding capacity information of each coder to the collection reporting server; the collecting and reporting server can communicate with the configuration server and send the hard coding capacity information of each coder to the configuration server; the configuration server may obtain the service scenario information and the hard coding capability information of each encoder to generate coding configuration parameters for each available encoder. When the encoding end generates video data and needs an encoder to encode, parameter query information is sent to a configuration server, corresponding encoding configuration parameters are obtained from the configuration server to determine a target encoder, the encoding end can be used for collecting encoding operation information of the target encoder during video encoding, the encoding operation information is sent to a collection and report server, the collection and report server can judge whether the target encoder is abnormal or not according to the encoding operation information, and if so, the collection and report server can inform the configuration server to update corresponding encoding configuration parameters, so that the encoding end updates the target encoder.

Wherein, an available encoder refers to an encoder on the encoding side that can be used to perform an encoding operation. Specifically, which encoders are available encoders can be determined according to the type and support of the encoders. For example, when the type of the encoder in the hard encoder capability information is H265, and the supporting case is supporting, then the H265 encoder is indicated as an available encoder; when the type of the encoder in the hard encoder capability information is H262 and the support case is not supported, the H262 encoder is declared to be a non-usable encoder.
