# 示例程序 Source: [https://docs.qualcomm.com/doc/80-70015-50SC/topic/example-applications.html](https://docs.qualcomm.com/doc/80-70015-50SC/topic/example-applications.html) Qualcomm IM SDK 包含了一些示例程序，可帮助您探索 Qualcomm Linux 的功能。这些应用程序可作为在 Qualcomm Linux 上运行定制用例的参考。 有两组主要示例程序可用于零售、AI Edge Box、IP 摄像头、无人机和机器人的不同用例。 - **AI/ML 应用程序**侧重于 AI 和 ML 功能。 - **多媒体应用程序**与摄像头、视频和音频相关。 ## 局限性 这些示例程序兼容 QCS6490 和 QCS9075。 但对于 QCS9075，**不支持摄像头**。输入源必须为文件或 RTSP 流。 ## 安装 要编译和安装示例程序，可选择以下方法之一： - 平台 eSDK：下载预编译的示例程序。相关说明，可参见[下载并安装 eSDK](https://docs.qualcomm.com/bundle/publicresource/topics/80-70015-51/install-sdk.html#download-and-install-esdk-)。 - GitHub 工作流：下载并编译 SDK 源代码，然后安装应用程序。下表提供了从 GitHub 下载示例程序的源路径： | 应用 | CodeLinaro
