标题： Implementing Video Monitoring Capabilities by using hardware-based Encoders of the Raspberry Pi Zero 2 W

摘要： 单板计算机，凭借其丰富的外部接口，为研究动植物在其自然栖息地提供了经济高效的解决方案。 随着Raspberry Pi Zero 2 W的引入，该设备提供了基于硬件的图像和视频编码器，现在可以将这一应用领域扩展到包括视频监控功能。 本文展示了一种解决方案，将视频流生成从中央处理器（CPU）卸载到基于硬件的编码器。 描述了编码应用程序中的数据流，随后介绍了一种通过减少内存复制次数来加速图像处理的方法。 本文最后以一个示例用例结束，展示了此新功能在水下相机中的应用。 显示英文摘要

摘要： Single-board computers, with their wide range of external interfaces, provide a cost-effective solution for studying animals and plants in their natural habitat. With the introduction of the Raspberry Pi Zero 2 W, which provides hardware-based image and video encoders, it is now possible to extend this application area to include video surveillance capabilities. This paper demonstrates a solution that offloads video stream generation from the Central Processing Unit (CPU) to hardware-based encoders. The flow of data through an encoding application is described, followed by a method of accelerating image processing by reducing the number of memory copies. The paper concludes with an example use case demonstrating the application of this new feature in an underwater camera.
