Embodiment 1

[0047] Such as 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] Such as 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 ...

Embodiment 2

[0055] Such as 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;...

Embodiment 3

[0066] Such as 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 conver...

Abstract

The invention discloses a multimedia transcoding scheduling method and apparatus. The multimedia transcoding scheduling method comprises the following steps that: classification processing is performed on original video files according to original multimedia file and target multimedia file attributes; and transcoding processing is performed on the original multimedia files according to classifications. According to the method of the invention, the original multimedia files are classified, and transcoding strategies are determined according to the classifications, and therefore, a transcoding server can be optimized; through optimizing scheduling strategies, fast transcoding can be realized under the premise that the hardware overhead of the transcoding server is not increased. With the multimedia transcoding scheduling method and apparatus of the invention adopted, the smoothness of video playing can be still ensured, and user experience can be improved under the situations that video calling conditions are complicated and video category sources are rich when video playing requests which are transmitted frequently and change frequently are fast responded.

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 ...
