# 编译并安装 Qualcomm IM SDK 插件 本节以 `mlvdetection` 插件为例，说明如何编译 Qualcomm IM SDK 插件并将其安装在设备上。 1. 搭建环境： cd $ESDK_ROOT Copy to clipboard source environment-setup-armv8-2a-qcom-linux Copy to clipboard SDK environment now set up; additionally you may now run devtool to perform development tasks. Run devtool --help for further details. [/local/mnt/workspace/QIMSDK_ESDK_6490/workspace/sources/qcom-gst-ai-classification]$ Copy to clipboard 2. 下载 Qualcomm IM SDK 插件源代码。 cd $ESDK_ROOT Copy to clipboard devtool modify qcom-gstreamer1.0-plugins-oss-mlvdetection Copy to clipboard 其中 `qcom-gstreamer1.0-plugins-oss-mlvdetection` 是下载插件源代码的 BitBake 配方。 NOTE: Starting bitbake server...
