detailed description

The idea of the present disclosure is to first obtain a publishing policy when publishing the multimedia content, and then, according to the publishing policy, automatically determine that the transcoding needs to be performed according to the transcoding control information in the publishing policy, and then perform the transcoding on the multimedia content, and The multimedia content is released after the transcoding is successful. While satisfying the user experience, the manual processing is eliminated, and the fault tolerance and processing efficiency are improved.

The specific embodiments of the present disclosure are further described below in conjunction with the accompanying drawings.

This embodiment provides a multimedia content publishing method. Referring to FIG. 1, the method includes:

S101. Perform a transcoding on the multimedia content when the transcoding control information is performed on the multimedia content, including the transcoding control information for performing the transcoding on the multimedia content.

S102: After the transcoding is completed, the transcoded multimedia content is released.

After the multimedia content is generated, it will be uploaded, that is, uploaded to the default server address. When uploading, the multimedia content will be reviewed, and logical processing such as packaging; the purpose of the review is usually to see whether the multimedia content meets the publishing conditions, and the publishing conditions are different according to the application scenario, such as not violating the state. Laws and regulations, etc.; packaging is to perform operations such as compression, so that the size of multimedia content is more reasonable. The multimedia content in this embodiment may include video content, audio content, image content, etc., and the transcoding operation may include conversion of a video bit rate, audio format conversion, or image format, pixel conversion, etc. The transcoding operation of the multimedia content in this embodiment.

For various reasons, it is necessary to perform transcoding on the multimedia content, and the transcoding may include changing the high code rate to a low code rate, or converting the low code rate to a high code rate, and cutting the multimedia content during the transcoding process. The grading process can be considered as transcoding of multimedia content. When the transcoding process is operated manually, the transcoding efficiency will be low and the accuracy cannot be guaranteed. Cause Thus, after the multimedia content is generated, its publishing policy is determined, and the publishing policy includes at least the transcoding control information for performing transcoding on the multimedia content. The publishing policy may be formulated by the user when uploading, and the user may formulate according to the needs of the user or the requirements of the system. The publishing policy shall at least include transcoding control information for performing transcoding on the multimedia content. The transcoding control information determines whether to perform transcoding on the multimedia content. After the multimedia content is uploaded, the system can automatically determine according to the transcoding control information in the publishing policy after no artificial determination.

The transcoding control information, in the present embodiment, should be easily recognized, so that work efficiency can be improved. Optionally, the transcoding control information includes a field value, and directly determining, according to the field value, whether a transcoding operation needs to be performed on the multimedia content. There are only two possibilities for transcoding. If the field defining the transcoding control information is Encode, then the field value can be Encode:0, Encode:1; where Encode:0 means no transcoding is required, and Encode : 1 indicates that transcoding is required, or conversely, this setting process can be arbitrary as long as the field values of the two are different.

After knowing the transcoding control information in the publishing policy, it can determine whether the transcoding of the multimedia content needs to be performed according to the transcoding control information therein. If the result of the judgment is that transcoding needs to be performed on the multimedia content, then the encoder needs to perform transcoding on the multimedia content. In this embodiment, the transcoding of the multimedia content may be transcoded according to the set rules; the rules of the setting are arbitrary, and some examples may be given below, in which the multimedia content is a video, and the transfer is guaranteed. The code rate is the same code rate, and the same code rate includes standard definition, high definition, ultra clear, blue light, etc., regardless of the source code of the source multimedia content, the transcoding is a uniform code rate; Or according to the current network conditions, the resolution of the multimedia content is uniformly reduced, which can also reduce the size of the multimedia content to a certain extent, and correspondingly, the code rate of the multimedia content can be uniformly increased; or different multimedia content Performing different transcodings, or segmenting the multimedia content at the time of transcoding, these various transcoding methods are feasible in this embodiment. The choice of encoder is also varied, and can be selected according to the type of multimedia content, such as the commonly used encoder with ENVIVO encoder and so on.

Optionally, the publishing policy in this embodiment may further include a source identifier and a target identifier; the source identifier includes source code rate information of the multimedia content, that is, the original code rate information of the uploaded multimedia content, and the target identifier includes a target of the multimedia content. Rate information, that is, code rate information of the transcoded multimedia content; that is, if it is determined from the transcoding control information that transcoding is required for the multimedia content, then when the publishing policy includes the source identifier and the target identifier, the encoder Perform transcoding of the multimedia content based on the source identifier and the target identifier. In other words, the original content rate multimedia content is transcoded to the target code rate. It is worth mentioning that the two parameters of the original bit rate and the target bit rate are not necessary. The publishing strategy may only include transcoding control information, and the optional transcoding process is implemented by the above method.

In addition, similar to the transcoding control information, the source identifier and the target identifier may also include a field value; directly according to the field value, it may be determined, what is the source code rate and the target bit rate of the multimedia content. For example, if the field of the source code rate is set to Bitrate, the corresponding field value is Bitrate: 2000 indicates the standard code rate, or the standard definition source, Bitrate: 8000 indicates the HD bit rate or the HD source, etc.; The code rate field is Definition, the corresponding field value is Definition: 0 means smooth code rate or smooth definition, Definition: 1 means SD code rate or SD definition, Definition: 4 means HD code rate. Or HD resolution. At the time of transcoding, the source code rate is determined according to the field value of Bitrate, and the target code rate is determined according to Definition, thereby performing the multimedia content. Transcode.

When multimedia content is uploaded, the multimedia content is naturally stored. The location of the storage is not certain, but the location where each multimedia content is stored is certainly indexable, and the location corresponding to each multimedia content storage has a storage path. After determining that the multimedia content needs to be transcoded, the storage path of the multimedia content needs to be sent to the encoder, and the encoder obtains the uploaded multimedia content from the storage path, and performs a transcoding operation on the multimedia content. In addition, after the transcoding, the multimedia content may also be stored, and the storage path is not necessarily consistent with the uploading time. Therefore, the encoder may be provided with a storage path after the transcoding of the multimedia content, thereby determining the transcoding after the transcoding. Storage location. The storage path in this embodiment includes a pre-transcoding and post-transcoding storage path, which may be in the form of a URL (Uniform Resource Locator), which exists in the publishing policy of the multimedia content, that is, according to The publishing policy, in addition to determining whether the multimedia content needs to be transcoded, can also determine the location stored before and after the multimedia content is transcoded.

Since the encoder performs the transcoding process on the multimedia content is not completed immediately, it is often necessary to monitor the transcoding completion degree of the multimedia content, that is, to monitor when the multimedia content is completed, so that the multimedia content can be released in time. Therefore, in this embodiment, the method further includes receiving the monitoring message according to a fixed time interval, and the sending of the monitoring message may be performed by a CIMP (Content Interface Management Platform) or by a CDNMGR/DB (Content Distribution Network). Manager/Database, System Management) to complete. The encoder 40 receives the monitoring message, and after the multimedia content transcoding is completed, feeds back the transcoding completion message according to the monitoring message, that is, the transcoding completion message is fed back to the corresponding device that sends the monitoring message according to the source of the monitoring message. The purpose of monitoring is to know the completion of transcoding of multimedia content in time, so as to carry out subsequent operations such as release, and improve work efficiency.

After the transcoding is completed, the multimedia content needs to be published. In a CDN (Content Distribution Network) system, there are often multiple media publishing servers, and it is sufficient for a multimedia content distribution to be published by only one media publishing server. Therefore, in this embodiment, The method further includes selecting a media publishing server according to a load balancing principle, and publishing the transcoded multimedia content by the selected media publishing server. Selecting the media publishing server according to the load balancing principle means that the load of each media publishing server is equal as much as possible. Generally speaking, it is often selected that the media publishing server with a small load publishes the transcoded multimedia content.

Of course, if it is determined at the outset that the transcoding control information does not need to perform transcoding on the multimedia content, then the multimedia content is directly published.

After the release is complete, the message of the completion of the release can be fed back. The feedback process can be from the media release server to the system management, to the content interface machine, to the device that uploads the multimedia content, that is, the CMS (Content Management System, content). Management system) to complete the entire release process.

By publishing the multimedia content in the manner of the embodiment, the efficiency of the transcoding can be accelerated, and the multimedia content can be released faster under the premise of ensuring the user experience.
