Problems solved by technology

It can be seen that none of the video encoding formats supported by the iOS system can encode the video with the Alpha channel, so that the video cannot be displayed transparently or semi-transparently in the iOS system.

Abstract

The invention discloses a video data processing method and device. The method comprises that preset to-be-decoded video data with original video data and masking data is obtained; the to-be-decoded video data comprises multiple separate unit display areas of the same size, and the original video data and the masking data are placed in the different unit display areas respectively; the to-be-decoded video data is decoded to obtain RGB values corresponding to the original video data and the masking data from the to-be-decoded video data; and the RGB value corresponding to the masking data is converted to a transparency value, and the decoded original video data is displayed in a transparent or semi-transparent manner according to the RGB value corresponding to the original video data and the transparency value corresponding to the masking data. According to the invention, videos are displayed in the ios system in the transparent / semi-transparent manner.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a video data processing method and device. Background technique [0002] The current practice of transparent / semi-transparent display of video is usually to reserve the Alpha channel (ie transparent channel) during video encoding, so that when the video is played in the future, the Alpha value of each pixel in the video can be obtained by decoding the video, and Blend with the basemap according to the Alpha value of each pixel to obtain a video that can be displayed transparently or semi-transparently. [0003] Currently, video encoding formats that can support alpha channels include: JPEG2000 (image compression standard based on wavelet transform), PNG (image file storage format), Planar RGB (an image file format), TGA (an image file format) , TIFF (Tag Image File Format, tag image file format), RLE (run-length encoding, run-length encoding). The video coding formats...
