Embodiment 1

[0047] like figure 1 As shown, the multimedia transcoding scheduling method in this embodiment includes steps:

[0048] S110. Classify the original multimedia file according to the attributes of the original multimedia file and the target multimedia file;

[0049] S120. Perform transcoding processing on the original multimedia files according to classification.

[0050] like figure 2 As shown, the multimedia transcoding scheduling device in this embodiment includes:

[0051] Classification device 10: used to classify the original multimedia file according to the attributes of the original multimedia file and the target multimedia file;

[0052] Transcoding device 20: used for transcoding the original multimedia files by category.

[0053] The invention classifies the original multimedia files and determines the transcoding strategy according to the category, so that the transcoding server can be optimized, and the fast transcoding can be realized without increasing the ha...

Embodiment 2

[0055] like image 3 As shown, this embodiment discloses a multimedia transcoding scheduling method, including steps:

[0056] S310. Obtain the original multimedia file;

[0057] S320. Perform transcoding processing on the original multimedia files according to classification.

[0058] Wherein, step S320 is roughly divided into the following four processing methods:

[0059] S321. If the original multimedia file is lower than the threshold and the file format conforms to a preset standard format, directly transcode.

[0060] S322. If the file format of the original multimedia file does not conform to the preset standard format, transcoding is performed after preprocessing the original multimedia file.

[0061] S323. If the size of the original multimedia file exceeds the threshold, but the file format conforms to the preset standard format, divide the original multimedia file into at least two segments, assign each segment to a different transcoding server for transcoding; tr...

Embodiment 3

[0066] like Figure 4 As shown, the multimedia transcoding scheduling device disclosed in this embodiment includes: a classification device, and a transcoding device coupled to the classification device.

[0067] The transcoding device further includes a slicer coupled to the classifier, a scheduler coupled to the classifier and the slicer respectively, a transcoding server coupled to the scheduler, a combiner coupled to the transcoding server, Coupling the multimedia storage server with the combiner; there is also a preprocessor between the classifier and the slicer;

[0068] The classification device classifies the original video file according to the original multimedia file and the attributes of the target multimedia file; the slicer is used to divide the original multimedia file into at least two segments; the scheduler is used to distribute the working performance of multiple transcoding servers The multimedia file to be transcoded; the preprocessor is used to convert t...

Abstract

The invention discloses a multimedia transcoding scheduling method and a multimedia transcoding scheduling device. The multimedia transcoding scheduling method comprises the steps of performing classifying treatment for original video files based on the attribute of the original multimedia files and the attribute of target multimedia files; and performing transcoding treatment for the original multimedia files according to the classification. As the original multimedia files are subjected to classification and a trancoding strategy is determined based on the classification, a transcoding server can be optimized; and through optimizing a scheduling strategy, rapid transcoding is realized without adding hardware expense of the transcoding server. According to the multimedia transcoding scheduling method and the multimedia transcoding scheduling device, smooth video playing can be still guaranteed under the conditions of complex video calling conditions and abundant video type sources which are caused in rapid response to multiple changeful video playing demands of users, and the user experience is improved.

Description

technical field [0001] The invention relates to the field of multimedia processing, in particular to a multimedia transcoding scheduling method and device. Background technique [0002] The popularization of the Internet and various electronic devices has made video transmission unprecedentedly widespread. A video content needs to be played repeatedly and concurrently on multiple platforms and terminals. [0003] Patent document CN 102802024A was published on November 28, 2012 as a transcoding method implemented on the server side, wherein the server side includes a host subsystem and a transcoding processing subsystem with multiple CPU cores, and the method includes: the The host terminal system defines the data stream attribute information of the transcoded data stream by calling parameter configuration; the host terminal system sends the data stream to be transcoded to the transcoding processing subsystem; the transcoding processing subsystem receives Decoding the data ...
