The method includes setting a video acquisition class in a programming language framework layer. With the video acquisition class inherits a class in a video acquisition underlying library and registers a callback function for the video acquisition underlying library. The video acquisition class sends a video acquisition command to the video acquisition underlying library and the video acquisition underlying library acquires video data according to the video acquisition command. The callback function is applied to acquire the video data from the video acquisition underlying library and the video data is sent to a coder for video data coding."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Video acquisition method and device","description":"A video acquisition method and device.
