Problems solved by technology

[0003] Using traditional technology to transmit video data, there are the following problems: putting screenshots and image compression on a single thread will generate a large time cost, and the real-time performance of data transmission cannot be guaranteed; the existing processing method is to combine screenshots and images Compression is done on two threads to reduce the processing time, but because the time complexity of screenshots is much lower than that of image compression, there is a case where the compression thread has just compressed one frame of image, but the screenshot thread has already intercepted four Five frames of images to memory; these four or five frames have very high content overlap, so the value of these few frames will be very small, and memory waste or even overflow will occur if it is used for a long time

Abstract

The invention discloses a cloud mobile phone data transmission method, comprising: acquiring framebuffer-readable video frame data according to a screenshot thread, and copying the video frame data to a preset video frame pile; pushing the video frame pile into the video frame Queue, and send a notification message to the coding thread through the pipeline; after receiving the notification message, the coding thread takes out the video frame data corresponding to the preset video frame pile from the video frame queue, and encodes the video frame data according to the encoder , generate video data to be transmitted; return the preset video frame stack to the video frame queue. The data transmission method, device and storage medium of a cloud mobile phone provided by the present invention can perform data transmission processing on data through two threads, and can optimize the memory space of the system while reducing the processing time with priority, thereby effectively improving data transmission. s efficiency.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a data transmission method, device and storage medium of a cloud mobile phone. Background technique [0002] The traditional method intercepts the RGB image of the screen of the cloud mobile phone through a single thread, and then compresses the image into H264 format data for video transmission. [0003] Using traditional technology to transmit video data, there are the following problems: putting screenshots and image compression on a single thread will generate a large time cost, and the real-time performance of data transmission cannot be guaranteed; the existing processing method is to combine screenshots and images Compression is done on two threads to reduce the processing time, but because the time complexity of screenshots is much lower than that of image compression, there is a case where the compression thread has just compressed one frame of image, but the s...
