Abstract

The invention aims to provide a multi-path output method and device for a vehicle-mounted video. The method comprises the steps of: obtaining vehicle-mounted video data of a vehicle in the driving process through a vehicle-mounted camera device; respectively checking current use performance information of a CPU and a GPU in the vehicle; determining the data conversion strategy of the vehicle-mounted video data according to the current use performance information of the CPU and the current use performance information of the GPU; performing data conversion on the vehicle-mounted video data through a data conversion strategy; and obtaining multiple paths of vehicle-mounted video output data corresponding to the vehicle-mounted video, wherein the resolutions of the multiple paths of vehicle-mounted video output data are different. When the vehicle-mounted video data is processed through the data conversion strategy determined according to the current use performance information of the CPUand the current use performance information of the GPU, the situation that the processing load of the vehicle-mounted terminal corresponding to the vehicle is too large can be avoided, and therefore the processing load of the vehicle-mounted terminal is guaranteed while multi-path data conversion of different resolutions is conducted on the vehicle-mounted video data.

Description

technical field [0001] The present application relates to the field of computers, in particular to a method and device for multiplex output of vehicle-mounted video recording. Background technique [0002] In the prior art, equipment such as driving recorder or monitoring has been very popular, and many customers need to obtain video data with different resolutions or more from the camera equipment. However, the video data obtained by the on-board camera equipment in most vehicles is processed by OpenGL, which leads to excessive consumption of the Graphics Processing Unit (GPU). For devices with low GPU performance If this video data processing method is adopted, it will be a disaster. Contents of the invention [0003] An object of the present application is to provide a method and device for multi-channel output of vehicle-mounted video recording, so as to solve the problem in the prior art that the processing load of the vehicle-mounted terminal is too large when the v...
