Detailed Description
The following description of the technical solutions in the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of a video on demand system provided in the present application.
In this embodiment, the video on demand system 10 includes a first P2P node 11 and a second P2P node 12.
In P2P (peer-to-peer), each node may serve other nodes as a resource provider, or may obtain the service for other nodes. In this embodiment, the first P2P node 11 serves as a resource to serve the second P2P node 12. The second P2P node 12 is the on-demand end.
The number of first P2P nodes 11 is a plurality. The first P2P node 11 may be a device such as a computer, router or smart phone capable of providing bandwidth, memory space and computing power. The second P2P node 12 may be a computer, a mobile phone, or a smart tv.
The second P2P node 12 receives an on-demand command from the user, where the on-demand command includes a video-on-demand transcoding parameter. The second P2P node 12 responds to the on-demand instruction to obtain the address of the first P2P node 11 storing the original video pointed to by the video on demand transcoding parameters. A connection request is initiated to the first P2P node 11 based on the address of the first P2P node 11.
The first P2P node 11 performs handshake verification on the connection request, and establishes a connection with the second P2P node 12 after the verification is passed.
After the first P2P node 11 establishes a connection with the second P2P node 12, the second P2P node 12 sends video on demand transcoding parameters to the first P2P node 11.
The plurality of first P2P nodes 11 perform distributed conversion processing on the original video according to the video on demand transcoding parameters, obtain a target video corresponding to the video on demand transcoding parameters, and send the target video to the second P2P node 12. Video transcoding is performed according to the video-on-demand requirement of the second P2P node 12, so as to obtain a target video, and video-on-demand can be ensured, and the first P2P node 11 does not need to pre-transcode and store videos corresponding to various transcoding parameters, so that the storage cost of data can be reduced.
The second P2P node 12 receives and plays the target video returned by the first P2P node 11.
Based on the video on demand system 10 described above, the present application provides the following embodiments:
referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of a video on demand method provided in the present application. The execution body of the embodiment is a first P2P node, and the embodiment may include the following steps:
step S11: the first P2P node responds to the connection request and establishes connection with the second P2P node.
Specifically, the second P2P node sends a query request to an index server in the P2P network, where the query request carries the original video file information; after receiving the query request of the second P2P node, the index server determines a first P2P node list storing the original video according to the original video file information carried by the query request.
The index server sends a first P2P node list stored with the original video to a second P2P node, the second P2P node sends a connection request to at least one first P2P node in the first P2P node list, and the first P2P node responds to the connection request and establishes connection with the second P2P node. Optionally, the second P2P node may select, according to the proximity principle, the first P2P node requesting connection from the first P2P node list, so as to reduce delay of data transmission and improve video on demand efficiency.
In the embodiment of the present application, the original video file information may be a Hash value (Hash) of the original video file. The hash value of the original video file is a unique value with a specific length obtained by carrying out hash operation on the original video file data by using a hash algorithm, and can be used as an identifier of the original video file.
Step S12: the first P2P node responds to the video on demand transcoding parameters from the second P2P node, and the original video pointed by the video on demand transcoding parameters is subjected to distributed conversion processing to obtain a target video corresponding to the video on demand transcoding parameters.
The number of the first P2P nodes is a plurality.
Specifically, after the first P2P node establishes a connection with the second P2P node, the first P2P node receives the video on demand transcoding parameter sent by the second P2P node. And the first P2P node converts the original video stored in the first P2P node into a target video corresponding to the video on demand transcoding parameter according to the video on demand transcoding parameter.
The first P2P node transcodes the original video in real time according to the video-on-demand requirement of the second P2P node, so that the first P2P node does not need to store target video corresponding to video-on-demand transcoding parameters in advance, a large amount of storage cost is reduced, and meanwhile, the first P2P node transcodes the original video in real time to ensure the hit rate of video-on-demand.
Wherein the video on demand transcoding parameters include, but are not limited to, resolution, file container format, video size, video frame rate, video bitrate, audio format, audio bitrate, audio sampling rate, number of audio channels, and the like.
In this embodiment, a plurality of first P2P nodes connected to the second P2P node participate in converting the original video into a target video corresponding to the transcoding parameters, and the plurality of first P2P nodes convert the original video into the target video in a distributed manner. Specifically, each first P2P node is responsible for conversion processing of a part of the original video, and the converted videos obtained by all the first P2P nodes are combined into a target video. For example, the time length of the original video is 90 minutes, the first P2P node a converts a 1-30 minute portion of the original video into a first target video corresponding to the video on demand transcoding parameter, the first P2P node b converts a 31-60 minute portion of the original video into a second target video corresponding to the video on demand transcoding parameter, the first P2P node c converts a 61-90 minute portion of the original video into a third target video corresponding to the video on demand transcoding parameter, and the first target video, the second target video and the third target video are combined to form the target video. Of course, the task amount of each first P2P node may be determined according to the performance of the first P2P node, and not each first P2P node may process an equal amount of original video, which is not limited in this application. And the calculation resources required to be consumed by converting the original video are distributed to each first P2P node, so that the transcoding resources required to be input can be reduced, and the transcoding efficiency of the original video is improved.
Step S13: the first P2P node sends the target video to the second P2P node.
Specifically, after the first P2P node completes conversion processing of the original video stored in the first P2P node according to the video on demand transcoding parameter to obtain the target video, the first P2P node sends the target video to the second P2P node.
In this embodiment of the present invention, the number of first P2P nodes may be one or more, when the second P2P node acquires the target video corresponding to the video transcoding parameter, an abnormality may occur in one or more first P2P nodes, for example, the first P2P node is down, powered off, etc., and the second P2P node cannot continuously acquire the target video corresponding to the video on demand transcoding parameter from the first P2P node having the abnormality; at this time, the second P2P node may acquire the target video corresponding to the video on demand transcoding parameter from the first P2P node that does not fail in the first P2P node list, so that the computing resources and the storage resources of each first P2P node may be fully utilized, and the hit rate of the on demand may be ensured.
For example, when the second P2P node obtains the first P2P node list from the index server as three devices a, b, and c, and the second P2P node obtains the target video corresponding to the video on demand transcoding parameters from the three devices a, b, and c, and when the device b is powered off, the second P2P node cannot obtain all the target videos corresponding to the video on demand transcoding parameters, at this time, the second P2P node may obtain the target videos corresponding to the video on demand transcoding parameters from the non-faulty devices a and c.
According to the video on demand transcoding method and device, the first P2P node responds to the video on demand transcoding parameters of the second P2P node and performs distributed conversion processing, so that target videos corresponding to the video on demand transcoding parameters are obtained and sent to the second P2P node, targeted transcoding is performed in real time according to video transcoding requirements, video on demand can be accurately played in a hit mode, and the problem that video on demand cannot be hit when a video source end does not store video files with a certain resolution in the related technology is solved. In addition, the video-on-demand method for carrying out distributed transcoding based on the P2P node in real time can fully utilize the computing resources of the P2P node, improve the transcoding efficiency, avoid storing pre-transcoding files and reduce a large amount of storage cost.
In order to enable the second P2P node to receive the target video corresponding to the video on demand transcoding parameter from the first P2P node more quickly and accurately, before converting the original video pointed by the video on demand transcoding parameter into the target video corresponding to the video on demand transcoding parameter, the present application may further enable the first P2P node to receive the video on demand range parameter from the second P2P node.
Referring to fig. 3, fig. 3 is a flow chart of a second embodiment of the video on demand method provided in the present application. The embodiment is a first embodiment of a video on demand method based on real-time transcoding by a P2P node, so the same steps are not repeated here, and specifically, the embodiment may include the following steps:
step S21: the first P2P node responds to the connection request and establishes connection with the second P2P node.
This step corresponds to S11 of the first embodiment of the video-on-demand method.
Step S22: the first P2P node receives a target resolution from the second P2P node.
Specifically, after the first P2P node establishes a connection with the second P2P node, the second P2P node sends a target resolution corresponding to the target video to the first P2P node.
The target resolution may be selected by the user through the second P2P node, or the second P2P node may be automatically adjusted according to the current network environment. For example, the current network environment is good, and the target resolution is high; the current network environment is not good, the blocking exists, and the target resolution is correspondingly lower.
Resolution is a parameter used to measure how much data is in an image, typically expressed as ppi, and a video is made up of innumerable pictures of the same resolution, the size of which determines the video sharpness. The larger the resolution is, the higher the definition of the video is, and the larger the occupied storage space is; whereas the lower the definition of the video, the less memory space is occupied.
The resolution of video has multiple levels, such as 360P, 720P, 960P, 1080P, 2K, 4K, etc. If the video is transcoded into videos with various resolutions in advance and stored, a considerable storage space is occupied, and the storage cost of the video is increased. After the first P2P node obtains the target resolution, S23 is executed, and the first P2P node does not need to store a large amount of videos with each resolution in advance, so that the storage cost of the videos is reduced.
Step S23: the first P2P node performs initialization preparation on the original video conversion processing.
Specifically, the initialization preparation includes setting parameters such as resolution, frame rate, code rate and the like for transcoding, and setting the parameters for transcoding, so that the first P2P node can respond to the data request command more quickly to transcode the original video.
Step S24: the first P2P node receives the video on demand range parameter from the second P2P node.
Specifically, the first P2P node receives a data request command sent by the second P2P node, where the data request command carries a video on demand range parameter.
Wherein the video on demand range parameter comprises, for example, a start time and an end time of the target video.
The second P2P node may send a data request command multiple times to the first P2P node to meet the user's demand for fast forward on demand.
Step S25: the first P2P node extracts a video part defined by the video on demand range parameter from the original video, and converts the video part into a target video with target resolution.
Specifically, after receiving a data request command carrying a video-on-demand range parameter sent by a second P2P node, the first P2P node extracts a video portion corresponding to the video-on-demand range parameter from an original video, and converts the video portion into a video of a target resolution according to the target resolution to obtain the target video. Therefore, the first P2P node can perform real-time transcoding according to the video on demand range parameter without transcoding the complete original video, so that the speed of the first P2P node responding to the second P2P node data request command can be increased, and the efficiency of converting the video part into the target video with the target resolution by the first P2P node is improved.
Step S26: and the first P2P node sends the target video to the second P2P node.
This step corresponds to S13 of the first embodiment of the video-on-demand method.
According to the embodiment, the first P2P node receives the target resolution and the video-on-demand range parameter sent by the second P2P node, and performs distributed conversion processing on the original video according to the target resolution and the video-on-demand range parameter to obtain the target video, so that the requirement of fast forward on demand of a user can be met, the first P2P node performs real-time transcoding according to the video-on-demand range parameter without transcoding the complete original video, and the speed of the first P2P node responding to the second P2P node data request command can be accelerated. In addition, the video-on-demand method based on the P2P node real-time transcoding can fully utilize the computing resources of the P2P node, does not need to store pre-transcoding files, and reduces a large amount of storage cost.
Next, the flow of the video on demand method will be described from the perspective of the second P2P node, referring to fig. 4, fig. 4 is a schematic flow chart of a third embodiment of the video on demand method provided in the present application. The embodiment may include the following steps:

The step is the same as step S11 of the first embodiment of the video on demand method, and thus will not be described herein.
Step S32: the second P2P node sends video on demand transcoding parameters to the first P2P node.
Specifically, the second P2P node detects the video on demand transcoding parameter requested by the video on demand request, and sends the video on demand transcoding parameter to the first P2P node, so that the first P2P node converts the original video pointed by the video on demand transcoding parameter into a target video corresponding to the video on demand transcoding parameter, the second P2P node can meet the on demand requirements of various different video on demand transcoding parameters, and the sending of the video on demand transcoding parameter enables the first P2P node to perform real-time transcoding, so that the hit rate of on demand can be ensured, and meanwhile, a large amount of storage cost is reduced.
Step S33: the second P2P node receives the target video corresponding to the video on demand transcoding parameters from the first P2P node.
According to the video on demand transcoding method and device, the second P2P node sends video on demand transcoding parameters to the first P2P node and receives target videos corresponding to the video on demand transcoding parameters, so that the second P2P node can save own computer resources, the video on demand requirements of various different video on demand transcoding parameters are met, the first P2P node carries out real-time transcoding by sending the video on demand transcoding parameters, the hit rate of video on demand can be guaranteed, and meanwhile a large amount of storage cost is reduced.
In order to enable the second P2P node to receive the target video corresponding to the video on demand transcoding parameter from the first P2P node more quickly, before the second P2P node receives the target video corresponding to the video on demand transcoding parameter from the first P2P node, the present application may further enable the second P2P node to send the video on demand range parameter to the first P2P node.
