Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. 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 invention.
Example one
Referring to fig. 1 and fig. 2, the present embodiment provides a fast playing method for video on demand, including:
receiving original video data uploaded by a user, and distributing the original video data to a nearby transcoding machine for video transcoding; the transcoded video data are transmitted to a temporary node which is deployed in the same machine room with a transcoding machine for caching, and the temporary node gradually distributes the cached video data to a corresponding storage node for storage; and acquiring a video-on-demand request, and preferentially acquiring video data from the storage node for playing when the corresponding video data is stored in the storage node, or else acquiring the video data from the temporary node for playing.
In the video-on-demand fast playing method provided by this embodiment, first, original video data uploaded by a user is received, and then the original video data is distributed to a transcoding machine in a nearby machine room based on a geographical position of the user to perform video transcoding to obtain video data, the video data is transmitted to a temporary node disposed in the same machine room as the transcoding machine to be cached, and then the cached video data is gradually distributed to a corresponding storage node by the temporary node to be stored on the ground, when a video-on-demand request is obtained, whether the corresponding video data is stored in the storage node is self-checked, if so, the corresponding video data is preferentially obtained from the storage node to be played, and if not, the corresponding video data is obtained from the temporary node to be played.
It can be seen that in this embodiment, after video transcoding is completed, the video is temporarily distributed to a temporary node in the same machine room as a transcoding machine for temporary storage, and when a user has a high requirement on real-time performance, a temporary video playing function can be provided through the temporary node, because the temporary node and the transcoding machine are distributed in the same machine room, and network transmission thereof belongs to intranet transmission, distribution can be completed within a short time (generally within 10 seconds), video on demand service can be provided without waiting for all videos to be distributed to a remote storage node, and after video data in the storage node is completely distributed to the storage node, the storage node preferentially provides video playing service.
In the above embodiment, before receiving the original video data uploaded by the user and distributing the original video data to a nearby transcoding machine for video transcoding, the method further includes:
correspondingly deploying a plurality of machine rooms in a plurality of regions, wherein each machine room is provided with at least one transcoding machine and two temporary nodes, and each machine room is provided with a plurality of remotely deployed storage nodes; the transcoding machine is respectively connected with the two temporary nodes, and each temporary node is respectively connected with the corresponding storage nodes.
In specific implementation, machine rooms need to be deployed in multiple regions throughout the country in advance, for example, machine rooms are deployed in three regions of beijing, shanghai and guangzhou respectively, a transcoding machine and a temporary storage cluster are deployed in each machine room of each region, one temporary storage cluster is generally composed of two temporary node machines, each machine room is generally remotely and correspondingly provided with multiple storage nodes, for example, 3 storage nodes, so that the transcoding machine is respectively in data connection with the two temporary nodes, and each temporary node is respectively in data connection with the 3 remote storage nodes. And a plurality of machine rooms are deployed nationwide, so that users can upload original video data more quickly and stably.
In the above embodiment, the method for receiving the original video data uploaded by the user and distributing the original video data to the nearby transcoding machine for video transcoding includes:
and the data distribution system receives the original video data uploaded by the user and selects a transcoding machine which is sent to the nearby machine room based on the position of the user to perform video transcoding.
In specific implementation, the original video data uploaded by a user is received through a video data distribution system, then the uploading position of the user is identified, and a nearby machine room is selected based on the position of the user and sent to a transcoding machine line for video transcoding. For example, the original video data uploaded by the user in suzhou is obviously closest to the shanghai computer room in suzhou, so that the transcoding machine of the shanghai computer room is selected to perform transcoding operation on the original video data.
In the above embodiment, the method for transmitting the transcoded video data to the temporary node deployed in the same machine room as the transcoding machine for caching, and then gradually distributing the cached video data to the corresponding storage node by the temporary node for storage includes:
the method comprises the steps of gradually transmitting transcoded video data to two temporary nodes in the same machine room for caching, and configuring attribute information of each temporary node, wherein the attribute information comprises playing priority and playing weight; and respectively distributing the video data cached in the temporary nodes to corresponding storage nodes for storage.
During specific implementation, transcoded video data can be synchronously distributed to 2 temporary nodes for storage, and the purpose of the 2 temporary nodes is set, so that on one hand, the pressure of video playing can be relieved, corresponding adjustment can be made according to the network bandwidth of a user, and service interruption caused by machine breakdown of one temporary node is avoided. On the other hand, when the temporary node distributes the data to the storage node, more distribution sources can be provided, so that the data distribution of the storage node can be completed more quickly.
It should be noted that the video data on the temporary nodes can already be played by the user on demand, because the video data in the two temporary nodes are the same, when the user requests to play, the video-on-demand system will select one of the temporary nodes to provide the video data for playing according to the priority weighting algorithm.
In the above embodiment, the method for acquiring a video-on-demand request, when the storage node stores corresponding video data, preferentially acquiring the video data from the storage node to play, and otherwise acquiring the video data from the temporary node to play includes:
acquiring a video-on-demand request initiated by a user through a video-on-demand system, and judging whether video data corresponding to the video-on-demand request is stored in any storage node corresponding to a nearby machine room; if the judgment result is yes, the corresponding video data is preferentially acquired from the storage node to be played; if the judgment result is negative, the corresponding video data is obtained from any temporary node of the nearby machine room based on the playing priority and the playing weight for playing.
In specific implementation, the playing priority of the storage node is higher than that of the temporary node, after all the video data are distributed to the storage node, the video-on-demand system can preferentially acquire the video data from the corresponding storage node for playing, namely preferentially play from the local storage, and if the storage node does not have a video data source on demand, acquire the video data from the temporary node for playing. The video data after the user transcoding can be rapidly distributed and played, and the requirement of the user on the real-time performance of video playing is met. As is well known, the bandwidth of the temporary node in the same computer room as the transcoding machine is relatively expensive, and after video data is distributed to the local storage node, the bandwidth of the local storage node is relatively cheap, and the video resources are reasonably distributed according to the priority, so that the playing request is preferentially played from the local storage node, and the bandwidth resources are saved.
In the above embodiment, the method for acquiring corresponding video data from any temporary node in the nearby computer room based on the play priority and the play weight to play includes:
comparing the playing priorities of two temporary nodes in the nearby machine room, and preferentially providing video data playing by the temporary node with the higher playing priority; when the playing priorities of the two temporary nodes in the nearby computer room are equal, the temporary node with high playing weight provides video data playing preferentially.
In specific implementation, each temporary node comprises attribute information which is respectively a playing priority and a playing weight, the playing service is provided with a priority with a high priority, and the playing service is provided with the temporary nodes with the same priority according to the order of the weight. For example, referring to table 1, if the priority of the temporary node a is 8 and the priority of the temporary node B is 7 in the same computer room, the temporary node a provides the playing service in preference to the temporary node B, and the weight values of the temporary node a and the temporary node B at this time are not functional. Referring to table 2, if the priorities of the temporary node a and the temporary node B are the same, the play order is given according to the weights. Generally, the weight value represents the distribution of the whole number of times of playing of the temporary node, and if the weight value of the temporary node B is 80, it indicates that nearly 80% of the number of times of temporary playing provided by the machine room is provided by the temporary node B, and if the weight value of the temporary node a is 20, it indicates that nearly 20% of the number of times of temporary playing provided by the machine room is provided by the temporary node a. Of course, the above algorithm may also be extended to be performed among multiple temporary nodes in the same computer room, so as to perform flexible node configuration selection.
| Temporary node | Priority of playing | Play weight |
| Temporary node A | 8 | 30 |
| Temporary node B | 7 | 70 |
TABLE 1
| Temporary node | Priority of playing | Play weight |
| Temporary node A | 6 | 20 |
| Temporary node B | 6 | 80 |
TABLE 2
In the above embodiment, when the temporary node providing video data playing in the machine room goes down, the temporary node is automatically switched to another temporary node to continue providing the remaining video data for playing. By the arrangement, the disaster recovery capability of the machine room can be improved, so that when one temporary node goes down, the other temporary node is switched to in an emergency to continue providing on-demand service for users. Optionally, when the downtime switching is completed, the temporary node which provides the on-demand service again can seamlessly provide the remaining video data for the user to play, so that the user is not sensitive, and the on-demand experience of the user is improved. Of course, it may also be set to provide complete video data for the user to replay when the downtime switching is completed, and the two schemes may be manually configured and selected by a developer in specific implementation, which is not described in detail in this embodiment.
In the above embodiment, the play priority and the play weight in the temporary node support dynamic adjustment based on the current on-demand number. In specific implementation, if the weight value of the temporary node B is 80, more than 80% of temporary playing times are provided by the temporary node B, and then when a new temporary on-demand request is received, the temporary node a is defaulted to provide the temporary playing service, so that reasonable utilization of resources can be ensured, and a certain temporary node is prevented from being overloaded for a long time.

the transcoding and distributing unit is used for receiving the original video data uploaded by the user and distributing the original video data to a nearby transcoding machine for video transcoding;
