Description

Multimedia data processing method, device and system

Technical Field

The present disclosure relates to the field of multimedia technologies, and in particular, to a method, an apparatus, and a system for processing multimedia data.

Background

In the current process of making video content (advertisement, movie, drama, short video) in the movie and television industry, a producer needs to shoot by using a camera to generate a video material file, then, after shooting is completed, the video material file is backed up, the backup is sent to an area for later production of the movie and television (usually, an office or a machine room far away from a shooting site) in a sending mode and the like, the processes of later clipping, color mixing, special effects and the like are carried out in the link of later production, and finally, a piece corresponding to the video content is output. In this process, the video material file shot by the camera can be almost only viewed and reviewed in the shooting site within one shooting cycle, which means that people who are not on the site cannot reach the video material file in the whole production process and cannot participate in the quality control of the video material file. On the other hand, the post-production worker also needs to wait for the completion of the shooting period to take the video material file and start the work flow of the video material file, and an invalid waiting time exists.

In recent years, some industry practitioners try to transmit video material files through internet and cloud storage, but because the video material files are large in size and slow in transmission, and even if the video material files are transmitted through the cloud storage, the video material files need to be uploaded only when the materials are backed up after shooting is completed, so that the time of a transmission route is only replaced by the time of uploading waiting, and the efficiency of a production process of the video industry is not really improved.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.

An exemplary embodiment of the present disclosure provides a method of processing multimedia data. As shown in fig. 1, fig. 1 is a flowchart illustrating a processing method of multimedia data according to an exemplary embodiment:

s101, acquiring multimedia data from a multimedia data acquisition device;

s102, encoding multimedia data to form a first multimedia file, wherein the code rate of the first multimedia file is smaller than that of a second multimedia file corresponding to the multimedia data;

s103, responding to the multimedia data acquisition request from the server, and sending the first multimedia file to the server.

In an exemplary embodiment of the present disclosure, the acquiring apparatus of the multimedia data in step S101 may refer to a device such as a camera, a monitor, or any other device that can acquire multimedia data, where the multimedia data may refer to composite data formed by data of video, audio, and other media, for example, acquiring video data from a camera, and acquiring audio data from a monitor. In step S102, the first multimedia file is formed by encoding the acquired multimedia data, the code rate of the first multimedia file is smaller than the code rate of the second multimedia file corresponding to the multimedia data, and since the ratio of the data amount of the file data before compression per second to the code rate is the compression ratio, the smaller the code rate is, the larger the compression ratio of the multimedia file is, the smaller the file volume is, and the first multimedia file can be transmitted to the server, so as to be used for the processing operation of the multimedia file by the subsequent service flow. When receiving the request for acquiring the multimedia data from the server in step S103, the first multimedia file with a small code rate is sent to the server, and the small code rate brings a large compression ratio, which can greatly reduce the volume of the multimedia file, facilitate the file transmission to the server, shorten the time, and improve the efficiency.

In an exemplary embodiment of the present disclosure, the processing method further includes:

In an exemplary embodiment of the present disclosure, the multimedia data obtained from the obtaining device of the multimedia data may form a second multimedia file, or the second multimedia file is obtained directly from the obtaining device, that is, the bitrate of the second multimedia file may be kept consistent with the bitrate of the obtained multimedia data. When a multimedia data acquisition request of a server side is received, whether a first multimedia file or a second multimedia file or both the first multimedia file and the second multimedia file are transmitted is determined by a preset rule. The first multimedia file and the second multimedia file are formed through different code rates, and the multimedia files with corresponding compression ratios can be uploaded to a server side according to uploading requirements.

The multimedia data can be encoded to form a first multimedia file, a third multimedia file, a fourth multimedia file and the like, the code rates of the encoded multimedia files are all smaller than those of the second multimedia file, specific numerical values of the code rates can be set according to requirements, for example, the code rates can be set according to the types of the obtained multimedia data and receiving conditions of a server end, a compression ratio range is determined, and when the first multimedia file and the third multimedia file are formed, a corresponding first compression ratio and a corresponding third compression ratio are selected in the compression ratio range respectively. For example, if the obtained multimedia data is video data of a movie, on the premise of ensuring the playing quality of the video data, the compression ratio range may be set to be 0.90 to 0.70 in consideration of the receiving condition of the server, the first compression ratio and the third compression ratio may be selected within the compression ratio range, and the first multimedia file or the third multimedia file may be selected for transmission as needed. The setting of the compression ratio range can also consider that the business process of the target user needs to set a smaller code rate, and a larger compression ratio range is determined, so that the compression ratio can be selected in the larger compression ratio range. For example, whether the size and code rate of the obtained multimedia file can be uploaded to the server normally through the network or not is judged, if not, the code rate is properly changed, the compression ratio is increased, and a fourth multimedia file is formed for transmission; for another example, whether the image quality of the multimedia file can meet the requirements of the user for subsequent service processes, and the numerical values of the code rate and the compression ratio are adjusted according to the image quality requirements. Therefore, when determining the code rate, the current network condition, the specification of the audio/video signal and the use of the final material need to be determined, after repeated tests are performed according to the actual condition, an optimal numerical value is selected as the code rate, and the compression ratio is determined to encode the obtained multimedia data to form a first multimedia file, a third multimedia file, a fourth multimedia file and the like. Furthermore, if the requirements for video data are high and the network conditions allow, it is possible to choose to transmit the second multimedia file, i.e. the original multimedia file that has not been subjected to the encoding compression process.
