Abstract

The invention provides a video decoding method. The method comprises the steps of applying for a predetermined number of frame buffers at a video acquisition stage, directly mapping the obtained frame buffers into a user space, performing format conversion on the acquired image data and coding the data, splitting video data and framing the video data for transmission, and running a receiving thread, a data processing thread and a decoding thread simultaneously in a pipeline system upon receiving one frame of data, decoding the data, performing format conversion on the decoded data and then displaying the data. The video decoding method has the advantages that the instantaneity of video data reading is optimized and the fluency of video is guaranteed. The acquisition, compressing, digital transmission and decoding of high-speed videos are completed by use of a simple structure and a technique easy to implement at low cost.

Description

technical field [0001] The present invention relates to video processing, in particular to a method for wirelessly transmitting and decoding video. Background technique [0002] With the emergence and popularization of wireless communication technology, it becomes possible to transmit real-time video through wireless network. The richness of terminal products makes the wireless network video transmission system widely used, such as wireless video surveillance, wireless videophone, video on demand, smart device TV live broadcast, mobile video conferencing, etc. However, the cost of the video playback mechanism in the wireless network environment is too high, and affected by the stability of the network, the real-time and fluency of video transmission and decoding also need to be further optimized. Contents of the invention [0003] In order to solve the problems in the above-mentioned prior art, the present invention proposes a video decoding method, including: [0004] U...
