Embodiment Construction

[0022] In order to make the purpose, technical solution and advantages of the present invention clearer, the following embodiments will take a video data acquisition device using an Android system as an example and further describe the present invention in detail in conjunction with the accompanying drawings.

[0023] figure 1 It is a structural diagram of Android system software in the prior art.

[0024] Depend on figure 1 It can be seen that the current Android system software is generally divided into four layers, namely the Linux kernel layer, the local framework and the Java runtime environment layer (including the hardware abstraction layer), the application framework layer and the application program layer.

[0025] The first layer is the Linux kernel layer, which generally includes a Linux operating system and a driver (Linux kernel), and is usually implemented by C language. Typically, Android core system services depend on the Linux 2.6 kernel, including: security...

Abstract

The embodiment of the invention provides a video acquisition method and a video acquisition device. The video acquisition method includes the following steps that: a camera acquisition class is set in a programming language framework layer, and the camera acquisition class inherits a video acquisition underlayer library and registers a callback function for the video acquisition underlayer library; the camera acquisition class transmits a video acquisition command to the video acquisition underlayer library, and the video acquisition underlayer library acquires video data according to the video acquisition command; and the callback function obtains the video data from the video acquisition underlayer library, and transmits the video data to an encoder for encoding the video data. With the video acquisition method and device of the invention adopted, the acquisition, coding and transmission of the video data can be realized locally at the programming language framework layer directly without a Java (JAVA) layer required, and therefore, copy and transmission time of the video data can be decreased, and the acquisition efficiency of the video data can be improved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of information processing, and more specifically, to a video collection method and device. Background technique [0002] Video capture devices such as mobile phones, shielded computers, and digital TVs generally have the need for video intercommunication. Video intercommunication is mostly realized through video streaming, which can not only maintain the continuity of video, but also ensure a certain real-time performance. However, a video capture device, such as a video capture device using an Android (Android) operating system, does not provide a standard interface to implement this video streaming service. As a result, when the above-mentioned video capture device is used for video capture, the video data transmission process is complicated, and the video data capture efficiency is not high. Contents of the invention [0003] The embodiment of the present invention proposes a...
