Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, it will be appreciated by those of ordinary skill in the art that numerous technical details are set forth in order to provide a better understanding of the present application in various embodiments of the present invention. However, the technical solution claimed in the present application can be implemented without these technical details and various changes and modifications based on the following embodiments.

A first embodiment of the present invention relates to a video interaction method, which is applied to an edge node, and a specific flow thereof is shown in fig. 1, including:

step 101, receiving a sharing link of a target video sent by a client;

102, acquiring a processing slice and an original slice of a target video according to a sharing link;

and 103, sending the original slice and the processed slice to the client.

The following describes details of the video interaction method of the present embodiment in detail, and the following only provides details for easy understanding, and is not necessary to implement the present embodiment.

In this embodiment, an edge node may be understood as an edge node in a CDN network; when a user requests to view a target video through a client, the CDN network allocates the client to an edge node, that is, the edge node provides a service for the client. When providing a video playing service for a client, an edge node generally adopts, for example, an HLS protocol (HTTP Live Streaming, HTTP-based media Streaming protocol) to transmit real-time audio and video; when the HSL protocol is used for transmitting the video to the client, the whole video is cut into a plurality of slices, the slices form a media file list which can be downloaded through HTTP, the client plays the downloaded slices in sequence, and the playing effect is still complete video.

The application scenario in this embodiment may be understood as one of the following application scenarios: the edge node in this embodiment is regarded as a first edge node, and receives a sharing link of a target video sent by a first client, where the sharing link includes a storage address of a processing slice of the target video, and the storage address of the processing slice points to a second edge node; that is to say, the first edge node is used for quickly acquiring the processing slice through the second edge node and sending the processing slice to the first client. The following describes the video interaction method in this embodiment by taking this application scenario as an example.

In step 101, a first edge node receives a sharing link of a target video sent by a client, where the sharing link includes a storage address of a processed slice of the target video. Specifically, the second edge node corresponds to a second client, and the second client can receive secondary processing of the user on the target video content when playing the target video, for example, adding a special effect to a target video picture; in this embodiment, the target video content is processed for the second time, that is, the original slice of the target video being played is processed, so as to obtain the processed slice of the target video; the second client uploads the processed slices of the target video to a second edge node for storage; the second edge node stores the processing slice and feeds back the storage address of the processing slice to the client; in this embodiment, a node corresponding to the storage address of the processing slice may be understood as a second edge node. It can be understood that, since the second client only uploads the processed slice to the second edge node, rather than uploading the entire processed target video to the second edge node, the occupation of the storage space of the second edge node is effectively controlled.

The second client side uploads the processed slices of the target video to a second edge node, and when the processed personalized video is expected to be shared, the second client side generates and sends a sharing link of the target video to the first client side; the first client sends the sharing link of the target video to the first edge node by clicking the sharing link, so that the first edge node can obtain the target video according to the sharing link.

In step 102, the first edge node obtains the processed slice and the original slice of the target video according to the sharing link. Specifically, since the sharing link includes the storage address of the processing slice of the target video, the first edge node may access the storage address to acquire the processing slice.

In an example, the sharing link for the target video may be:

http: zhongchaobisaii.m 3u 8/ip: 172.168.4.1; here, "ip" 172.168.4.1 denotes a storage address of the processed slice.

It is to be understood that, in another example, the sharing link of the target video may further include a modification flag, where the modification flag is a processed flag or an unprocessed flag: after the second client uploads the processing slice to the second edge node, the sharing link generated by the second client may include the processed identifier, so that the first edge node may continue to go to the second edge node to obtain the processing slice when obtaining the processed identifier from the sharing link; when the sharing link generated by the second client includes the unprocessed identifier, the first edge node acquires the unprocessed identifier from the sharing link, which indicates that the first edge node does not need to acquire the processed slice, and the original target video can be provided to the first client. In another example above, the analysis link for the target video may be:

http, zhongchaobisaii.m 3u8/modify 1& ip 172.168.4.1; here, "modification ═ 1" is a processed flag, and indicates that the target video has been processed twice.

In this embodiment, a specific implementation manner of obtaining the processing slice in step 102 is provided, as shown in fig. 2, including steps 1021 to 1022.

Step 1021, acquiring a slice index table of the target video according to the storage address;

and step 1022, acquiring the processed slice according to the identification information of the processed slice.

Specifically, after receiving the processing slice uploaded by the second client, the second edge node stores the identification information of the processing slice in the form of an index table so as to clearly manage the processing slice and facilitate searching; the identification information of the processed slice may include identification information of the original slice being processed so as to be stored corresponding to the identification information of the original slice. In an example, the index table may be in the form of table 1 below, where the slice file is a.ts file, and no corresponding processed slice indicates that the original slice was not processed a second time; taking the processing slice identification information "001 _ special effect 1. ts" as an example, the identification information indicates that the second edge node stores the processing slice obtained by adding the special effect 1 to the original slice 001. ts.

TABLE 1

Original slice identification information	Machining slice identification information
		001.ts	001_ special effects 1.ts
002.ts
		003.ts
004.ts	004_ Special Effect 2.ts
		……

The first edge node can access the second edge node according to the storage address of the processing slice to obtain a slice index table of the target video, and obtain the processing slice from the second edge node according to the identification information of the processing slice recorded in the slice index table; since many slices may be stored in the second edge node, the first edge node can quickly acquire the processed slice in the above manner.

In this embodiment, a specific implementation manner of obtaining the original slice in step 102 is provided, as shown in fig. 3, including steps 1023 to 1024.

Step 1023, according to the address of the description file, obtaining the description file of the target video;

and step 1024, acquiring the original slice according to the original slice recorded in the description file.

Specifically, the sharing link of the target video comprises an address of the description file; in an example, the sharing link for the target video may be: http: zhongchaobisaii.m 3u 8/ip: 172.168.4.1; wherein http is the address of the description file; then, the address of the description file can be accessed according to the sharing link, so that the description file of the target video can be acquired. The description file is used for recording an original slice corresponding to the target video and a slice playing sequence of the target video; in an example, when transmitting a video to a client using an HSL protocol, an entire video is cut into several slices, and an m3u8 file (i.e., a description file) is generated at the same time, the m3u8 file is used for recording an original slice corresponding to the video, and a slice playing order of the video; the content contained in the original m3u8 file of a target video can be as follows:

#EXTM3U

#EXT-X-VERSION:3

#EXT-X-TARGETDURATION:10

#EXT-X-DEFINE:keyframeurl＝http://……xml

#EXT-X-INF:10.000

001.ts

002.ts

003.ts

004.ts

……

#ENDLIST

the content of the m3u8 file indicates that the original slices corresponding to the target video comprise 001.ts, 002.ts, 003.t and 004.ts … …, and the original slices are played in the order of 001.ts, 002.ts, 003.ts and 004.ts … …. It can be understood that the original slice corresponding to the target video can be obtained from the description file of the target video, and the original slice is further obtained.

It can be understood that, if other clients have already obtained the original slice of the target video through the first edge node before the first edge node receives the sharing link of the target video sent by the first client, the original slice of the target video may be stored in the local cache of the first edge node; therefore, after the original slice corresponding to the target video is obtained, whether the original slice is stored in the local cache of the first edge node is judged, if yes, the first edge node can directly extract the original slice from the local cache and send the original slice to the first client, and therefore time consumption for providing service for the client is shortened.

If the original slice is not stored in the local cache of the first edge node, see the steps in another video interaction method in this implementation, as shown in fig. 4.

Step 201, receiving a sharing link of a target video sent by a client; this step is substantially the same as step 101, and is not described herein again.

Step 202, obtaining a processing slice according to the sharing link; this step is substantially the same as the description of "obtaining a processed slice" in step 102, and is not described here again.

Step 203, sending a request for obtaining the original slice to the node corresponding to the storage address of the processed slice.

Step 204, judging whether an original slice fed back by a node corresponding to the storage address of the processed slice is obtained; if yes, go to step 206; if not, go to step 205.

Step 205, sending a request for obtaining the original slice to the source node.

Specifically, as described in step 101, the second client uploads the processed slice obtained by processing the original slice of the target video to the second edge node for storage, and the original slice is sent from the second edge node to the second client, so in this embodiment, a node corresponding to the storage address of the processed slice may be understood as the address of the second edge node, and the local cache of the second edge node may store the original slice of the target video, so that the first edge node may request to obtain the original slice from the second edge node; if the second edge node does not cache the original slice, the original slice cannot be fed back to the first edge node, and the original slice of the target video is uniformly issued by the source node, the first edge node requests the source node for the original slice of the target video.

After the original slice is obtained, step 206 is executed to send the original slice and the processed slice to the client. This step is substantially the same as step 103, and is described below.

In step 103, the first edge node sends the original slice and the processed slice to the client, so that the first client can play the processed slice. In this embodiment, the first edge node may send the original slice and the processed slice according to the slice playing order recorded in the description file, so that the first client may play the original slice and the price slice according to the slice playing order, and the user sees the processed target video through the first client.

Specifically, after the second edge node receives the processed slice uploaded by the second client, the m3u8 file is updated, and the processed original slice in the slice playing sequence is replaced by the processed slice; for example, the content included after the update of the m3u8 file in the above example can be as follows:

#EXTM3U

#EXT-X-VERSION:3

#EXT-X-TARGETDURATION:10

#EXT-X-DEFINE:keyframeurl＝http://……xml

#EXT-X-INF:10.000

001_ special effects 1.ts

002.ts

003.ts

004_ Special Effect 2.ts

……

#ENDLIST

The content of the m3u8 file indicates that the slices of the target video are played in the order of 001_ special effect 1.ts, 002.ts, 003.ts, 004_ special effect 2.ts … …; that is, the first edge node also sends the slices in the order of 001_ special effect 1.ts, 002.ts, 003.ts, 004_ special effect 2.ts … …, so that the target video to which the video special effect is added is viewed on the first client of the user.

In addition, it can be understood that the edge node may periodically access according to the sharing link to obtain the latest slice index table and the m3u8 file, that is, obtain the latest uploaded processed slice and send the slice to the client according to the latest slice playing order. In an example, the edge node may access the client according to the sharing link after sending an original slice or a processed slice to the client, and if the slice index table is found to be updated, obtain the latest processed slice, obtain the latest m3u8 file, and send the next slice to the client according to the latest slice playing order.

In addition, the edge node may provide services for a plurality of clients, for example, when the edge node further receives a sharing link to a target video sent by another client, since the same service is already provided to the client before, the edge node may continue to provide the same service to another client without acquiring the original slice and the processed slice again, so as to shorten the time consumed for providing services to the client and accelerate the provision of services to the client.

Compared with the prior art, the edge node receives a sharing link of a target video sent by a client; the sharing link comprises a storage address of a processing slice of the target video; acquiring a processing slice and an original slice of a target video according to the sharing link; sending the original slices and the processed slices to a client; it can be understood that, because the client acquires the target video through the service provided by the edge node, and the sharing link sent by the client includes the storage address of the processing slice, the edge node can quickly acquire the personalized processing slice according to the storage address of the processing slice, that is, the client can quickly acquire the target video processed by other clients without waiting for the process of uploading the processing slice to the source node and then uniformly issuing the processing slice to the edge node by the source node.

A second embodiment of the present invention relates to a video interaction method, which is applied to an edge node, and is substantially the same as the first embodiment, except that the original slice sent to the client is filtered. Since the original slice may be already stored in the local cache of the edge node, or needs to be obtained from the outside, the embodiment chooses to use the example that the original slice is already stored in the local cache of the edge node as an example for illustration. The specific flow of the video interaction method in this embodiment is shown in fig. 5, and includes the following steps.

Step 301, receiving a sharing link of a target video sent by a client; this step is substantially the same as step 101, and is not described herein again.

Step 302, acquiring a processing slice and an original slice of a target video according to a sharing link; this step is substantially the same as step 102 and will not be described herein.

And step 303, screening unprocessed original slices from the original slices according to the slice index table.

Specifically, as can be seen from table 1 in the first embodiment, the unprocessed original slices are 002.ts and 003.ts, and therefore 001.ts and 004.ts are removed from the original slices, and only 002.ts and 003.ts are retained as original slices to be sent to the client. In this way, the number of slices sent to the client and the occupation of the storage space of the client are reduced.

Step 304, sending the processed slices and unprocessed original slices to a client according to the slice playing sequence; this step is substantially the same as step 103, and is not described herein again.

In addition, the edge node can send selectable items to the client before sending the slices to the client, so that a user using the client can select whether to watch the unprocessed target video or the secondarily processed target video, and then sends the corresponding slices to the client according to the selection of the user, and good video interaction experience is provided for the user.

Compared with the prior art, the present embodiment sends the original slice of the target video to the client, and includes: screening unprocessed original slices from the original slices according to the slice index table, and sending the processed slices and the unprocessed original slices to a client; because the video finally received by the client is formed by combining the processed slices and the unprocessed slices, the original slices corresponding to the processed slices are removed, the data volume transmitted to the client by the edge nodes is reduced, and the occupation of the storage space of the client is reduced, so that the client can acquire the processed target video more quickly, and the service is provided for the client at an accelerated speed.

The third embodiment of the invention relates to a video interaction method, which is applied to edge nodes; the specific flow of the video interaction method in this embodiment is shown in fig. 6, and includes:

step 401, sending an original slice of a target video to a client;

step 402, receiving and storing a processing slice of a target video uploaded by a client according to an original slice;

and step 403, feeding back the storage address of the processing slice to the client.

Specifically, when a user requests to view a target video through a client, the CDN network allocates the client to an edge node, and the edge node provides a service for the client and sends an original slice of the target video to the client. When the client plays the target video, the client can receive secondary processing of the user on the target video content, for example, adding a special effect to a target video picture, that is, processing an original slice of the target video being played to obtain a processed slice of the target video, and uploading the processed slice of the target video to an edge node; and the edge node receives and stores the processing slice of the target video sent by the client and feeds back the storage address of the processing slice to the client.

When a client wants to share out the processed personalized video, the client generates and sends a sharing link of a target video to another client, wherein the sharing link comprises a storage address of a processing slice; and another client sends the sharing link of the target video to the edge node corresponding to the other client by clicking the sharing link, so that the edge node corresponding to the other client can acquire the processing slice according to the storage address of the processing slice.

In addition, the edge node feeds back the address of the description file to the client, and the sharing link generated and sent by the client to another client also comprises the address of the description file, so that the edge node corresponding to the other client can acquire the description file according to the address of the description file; the description of the description file is substantially the same as that in the first embodiment, and is not repeated herein.

It can be understood that, because the client only uploads the processed slice to the edge node, rather than uploading the whole processed target video to the edge node, the occupation of the storage space of the edge node is effectively controlled; the processing slices stored by the edge nodes can be rapidly acquired to be shared to other clients, so that the convenience of interaction among the clients is effectively improved, and the process of providing service for the clients by the edge nodes is accelerated.

The fourth embodiment of the invention relates to a video interaction method, which is applied to a client; the specific flow of the video interaction method in this embodiment is shown in fig. 7, and includes:

step 501, receiving an original slice of a target video sent by an edge node;

step 502, uploading a processing slice of a target video to an edge node according to an original slice, and receiving a storage address of the processing slice fed back by the edge node;

step 503, generating a sharing link of the target video, and sending the sharing link to another client.

Specifically, when a user requests to view a target video through a client, the CDN network allocates the client to an edge node, and the edge node provides a service for the client and sends an original slice of the target video to the client. When receiving and playing the original slice sent by the edge node, the client can perform secondary processing on the original slice, for example, adding a special effect to a target video picture, and the like to obtain a processed slice of the target video, and upload the processed slice of the target video to the edge node; and after receiving and storing the processing slice of the target video sent by the client, the edge node feeds back a storage address of the processing slice to the client.

In addition, the client side also receives the address of the description file fed back by the edge node, and the sharing link generated by the client side and sent to another client side also comprises the address of the description file, so that the edge node corresponding to another client side can acquire the description file according to the address of the description file and further acquire the original slice of the target video; the description of the description file and the original slice is substantially the same as that in the first embodiment, and will not be described herein.

It can be understood that, because the sharing link sent by the client includes the storage address of the processing slice, the edge node can quickly acquire the personalized processing slice according to the storage address of the processing slice, that is, the client can quickly acquire the target video processed by other clients without waiting for uploading the processing slice to the source node and then uniformly issuing the processing slice to the edge node by the source node.

A fifth embodiment of the present invention relates to a video interactive system, including: the system comprises a first client, a first edge node, a second client and a second edge node, wherein the first client corresponds to the first edge node, and the second client corresponds to the second edge node.

The method comprises the steps that a first edge node sends an original slice of a target video to a first client; the first client can receive the secondary processing of the original slice by the user to obtain a processing slice of the target video, and transmits the processing slice to the first edge node; and after receiving and storing the processing slice, the first edge node feeds back the storage address of the processing slice to the first client. Since the first client only uploads the processed slice to the first edge node, rather than uploading the entire processed target video to the first edge node, the occupation of the storage space of the first edge node is effectively controlled.

When a first client wants to share out the processed personalized video, the first client generates a sharing link of the target video and sends the sharing link to a second client, and the sharing link includes a storage address of the processed slice.

The second client sends the sharing link of the target video to the corresponding second edge node, so that the second edge node quickly accesses the storage address of the processing slice to obtain the processing slice according to the sharing link without waiting for uploading the processing slice to the source node, and then the source node uniformly issues the processing slice to the edge node.

In addition, the first edge node also feeds back an address of the description file to the first client, that is, the sharing link generated by the first client also includes the address of the description file, so that the second edge node accesses the address of the description file according to the sharing link to obtain the description file, and further obtains the original slice of the target video; the description of the description file and the original slice is substantially the same as that in the first embodiment, and is not repeated here.
