Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] Such as figure 1 In the described embodiment, a method for implementing transcoding test evaluation using video features specifically includes the following steps:

[0020] (1) The source file enters the analysis, the feature information is obtained through the source file feature analysis module, and the video length segmentation is realized with the feature information; specifically: because there are different scenes in the source file, the scene distinction of the source file is realized through the scene detection algorithm, according to the existing The video feature extraction algorithm realizes the extraction of video features. After the video feature extraction is completed, the feature results are summarized and the aggregation statistics of similar feature results are realized, and then the video segmentation is realized by co...

Abstract

The invention discloses a method for realizing transcoding test evaluation by using video features. The method specifically comprises the following steps: (1) analyzing a source file, obtaining feature information through a source file feature analysis module, and realizing video length segmentation through the feature information; (2) combining just analyzed source video feature information to obtain transcoding parameters meeting requirements through a transcoding parameter collection and analysis module; (3) matching the video clips obtained in the step (1) with the transcoding parameters obtained in the step (2), and realizing quality analysis through a result obtained by transcoding of a feature clip transcoding module; and (4) after video evaluation is carried out through a transcoding output quality analysis module, if the video quality evaluation is poor, returning to the step (2), and if the video quality evaluation is good, transcoding and outputting a comparison source video, and outputting a file to realize analysis and evaluation. The beneficial effects of the invention are that the method achieves the cumulative combination of data, and achieves the final high-quality and low-code-rate effect of a video.

Description

technical field [0001] The present invention relates to the technical field of video transcoding, in particular to a method for implementing transcoding test and evaluation by using video features. Background technique [0002] There are various parameter combinations in video encoding, but due to the diversity of sources and output requirements, it is impossible for a person with professional video knowledge to quickly combine reasonable and effective encoding parameters. Contents of the invention [0003] The present invention aims to overcome the above-mentioned deficiencies in the prior art, and provides a high-quality and low-bit-rate method for implementing transcoding test evaluation by using video features. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: [0005] A method for utilizing video features to realize transcoding test evaluation, specifically comprising the following steps: [0006] (1) sour...
