[0002] With the development of the Internet, accessing and transmitting media resources is becoming more and more popular. When users access and transmit media resources, streaming media technology can ensure the stability and continuity of media streams, and media gateways can convert and process media streams to improve user experience. One type of media gateway is a device used for audio and video media stream transmission. This hardware device is equipped with dual gateways as standard. Its main function is to extract audio and video media streams from the network card connected to the local area network and push the media streams to users through the network card connected to the external network.

[0003] During the process of media stream forwarding, if the network is blocked and unstable or the user end is mistakenly closed, the end of the media gateway pushing the media stream will be closed. However, in order to avoid media stream leakage, the end of the media gateway pulling the media stream also needs to be closed at the same time. If the network is restored in a short time or the user reopens it, the ports for pushing the media stream and closing the media stream need to be reopened, so business recovery cannot be completed quickly.

[0044] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0045] In one embodiment, the present application provides a method for releasing media resources. The following embodiments are described by taking the method applied to a media gateway as an example. It can be understood that the media gateway executing the method for releasing media resources can be a single media gateway or a media gateway cluster composed of multiple media gateways, and the present application does not impose any specific restrictions on this. Figure 1 As shown, the method specifically comprises the following steps:

[0046] S101: When receiving an access instruction for accessing a target media resource, if the first container of the media gateway has an identifier of the target media resource, copying the identifier to the second container of the media gateway;

[0047] In this step, when an access instruction for accessing a target media resource is received, it is determined whether an identifier of the target media resource exists in the first container of the media gateway, and if so, the identifier is copied to the second container of the media gateway;

[0048] The first container and the second container are a data structure, such as a map data structure, located in the media gateway, and used to store relevant information of media resources. The relevant information includes but is not limited to an identifier of the media resource, which is used to manage the media resource and can call and release the media resource according to the identifier.

[0049] Furthermore, the data structures of the first container and the second container are completely the same, the first container is used to store media resources waiting to be released, and the second container is used to store currently active media resources. If the identifier of the target resource exists in the first container, it indicates that the target resource has been stored in the media gateway and the target media resource can be directly reused.

[0050] S102: Pushing the target media resource through the first network card port of the media gateway based on the identifier in the second container;

[0051] In this step, according to the identifier stored in the second container, the target media resource is pushed through the first network card port of the media gateway, wherein the first network card port of the media gateway is connected to an external network for pushing media resources.

[0052] It can be understood that if the identifier exists in both the first container and the second container, it indicates that the target resource is in a normal transmission state.

[0053] S103: when receiving a closing instruction for closing the target media resource, removing the identifier from the second container, closing the first network card port, and keeping the second network card port of the media gateway open, wherein the second network card port is used to obtain media resources;

[0054] In this step, if the network is blocked instantaneously or the user mistakenly closes the user terminal, the media gateway will receive a closing instruction for closing the target media resource. After receiving the closing instruction, the identifier is removed from the second container, and the first network card port is closed, and the media resource is no longer pushed, while the second network card port of the media gateway is kept open. The second network card port of the media gateway is connected to the local area network and is used to obtain media resources from the media source.

[0055] It can be understood that if the identifier exists in the first container but does not exist in the second container, it indicates that the target resource is in a delayed closing state.

[0056] S104: If no access instruction for accessing the target media resource is received within a preset time period, the identifier is removed from the first container, the target media resource is released, and the second network card port is closed.

[0057] In this step, it is determined whether an access instruction for accessing the target media resource is received within a preset time period. If not, the identifier in the first container is removed, the target media resource is released, and the second network card port is closed to avoid leakage of media resources.

[0058] The preset time period can be flexibly set according to the actual application scenario. Removing the identifier is to delete the identifier in the first container, and releasing the target media resource is to delete the target media resource in the media gateway to release the memory space originally occupied by the target media resource.

[0059] It can be understood that if the identifier does not exist in either the first container or the second container, it indicates that the target resource is in a state of being released.

[0060] The present application provides a method, device, storage medium and media gateway for releasing media resources. The method includes: when an access instruction for accessing a target media resource is received, if the first container of the media gateway has an identifier of the target media resource, the identifier is copied to the second container of the media gateway; based on the identifier in the second container, the target media resource is pushed through the first network card port of the media gateway; when a closing instruction for closing the target media resource is received, the identifier is removed from the second container, the first network card port is closed, and the second network card port of the media gateway is kept open, wherein the second network card port is used to obtain media resources; if the access instruction for accessing the target media resource is not received within a preset time period, the identifier is removed from the first container, the target media resource is released, and the second network card port is closed. By setting the identifiers of the first container and the second container to store media resources in the media gateway, it is convenient to manage media resources; by pushing media resources according to the identifiers of media resources, it is possible to quickly call media resources; when a user closes a media resource, a preset time period is used as a buffer to delay the release of the media resource. When the user accesses again, the media resource can be directly reused, thereby achieving rapid recovery of the service and optimizing the transmission of media streams in an environment with large network jitter.

[0061] In one embodiment, the method further comprises:

[0062] When receiving an access instruction for accessing the target media resource, if the identifier of the target media resource does not exist in the first container, sending a signaling for requesting the target media resource to the media source through the second network card port to trigger the media source to send the target media resource to the media gateway;

[0063] An identifier of the target media resource is determined, and the identifier is copied to the first container and the second container.

[0064] Specifically, when the media gateway receives an access instruction for accessing the target media resource, if the identifier of the target media resource does not exist in the first container, the media gateway can send a signaling for requesting the target media resource to the media source through the second network card port. When the media source receives the signaling, it sends the target media resource to the media gateway according to the signaling. The media gateway determines the target media resource and copies the identifier to the first container and the second container.

[0065] It can be understood that by judging whether the identifier of the target media resource exists in the first container, it is possible to quickly determine whether the target media resource exists in the media gateway, thereby facilitating the management of various media resources in the media gateway. After determining the identifier of the target media resource, the identifier is copied to the first container and the second container, thereby ensuring that the target media resource can be transmitted normally.

[0066] In one embodiment, the step of determining the identifier of the target media resource includes:

[0067] Obtain the name and type of the target media resource;

[0068] An identifier of the target media resource is determined according to the name and the type.

[0069] Specifically, after acquiring the target media resource, the media gateway may determine the identifier of the target media resource according to the name and type of the target media resource.

[0070] Furthermore, each media resource in the media source has a corresponding name, and the name can be displayed in the user terminal, and each media resource has a corresponding type, including but not limited to main stream, sub-stream and 4K, etc. According to the name and type corresponding to the target media resource, an identifier corresponding to the target media type can be generated.

[0071] It can be understood that determining the identifier according to the name and type of the target media resource can ensure the uniqueness of the identifier of the target media resource, thereby improving the accuracy of calling the target media resource.

[0072] In one embodiment, when a closing instruction for closing the target media resource is received, after the step of removing the identifier from the second container, the method further includes:

[0073] Within the preset time period, it is determined whether an access instruction for accessing the target media resource is received according to a preset frequency.

[0074] Specifically, within the preset time period, it is determined according to the preset frequency whether the media gateway has received an access instruction for accessing the target media. For example, it may be determined once every ten seconds within one minute whether an access instruction for accessing the target media resource has been received.

[0075] The preset time period is used to delay the release of the target resource, and the preset frequency can be determined according to an actual application scenario.

[0076] It is understandable that, by determining whether an access instruction for accessing the target media resource is received within the preset time period according to a preset frequency, it is possible to more quickly determine whether to push the target media resource, thereby improving the response speed of the media gateway.

[0077] In one embodiment, when receiving an access instruction for accessing a target media resource, if the first container of the media gateway has an identifier of the target media resource, before the step of copying the identifier to the second container of the media gateway, the method further includes:

[0078] Receive user login information;

[0079] Matching the user's login information with the user's account information;

[0080] If the match is successful, a prompt indicating successful login is issued, and the user obtains permission to access the media resources;

[0081] If the match fails, a prompt indicating login failure is issued, and the user does not obtain permission to access the media resource.

[0082] Specifically, before receiving the access instruction, it is necessary to first receive the user's login information, and match the user's login information and account information. If the match is successful, the user information authentication is passed, a prompt of successful login is issued, and the user obtains the authority to access the media resources, and can access the media resources by sending signaling to the media gateway; if the match fails, the user information authentication is not passed, a prompt of failed login is issued, and the user does not obtain the authority to access the media resources.

[0083] It is understandable that before receiving the access instruction, the user information is verified to ensure the security and reliability of the media resource access.

[0084] In one example, if Figure 2 As shown, the media resource release method provided by this application may include the following steps:

[0085] S201: access target media resources;

[0086] S202: Determine whether there is an identifier of the target resource in the first container;

[0087] S203: If yes, copy the identifier in the first container to the second container;

[0088] S204: Push the target media resource through the first network card port according to the identifier in the second container; then execute S208;

[0089] S205: If not, obtaining the target media resource from the media source through the second network card port;

[0090] S206: Determine the identifier of the target media resource;

[0091] S207: copy the identifier to the first container and the second container; then execute S204;

[0092] S208: closing the target media resource;

[0093] S209: remove the identifier in the second container, close the first network card port, and keep the second network card port open;

[0094] S210: Determine whether to access the target media resource within a preset time period; if yes, execute S201;

[0095] S211: If not, remove the identifier in the first container, release the target media resource, and close the second network card port.
