# 创建自己的 Qualcomm IM SDK 插件 Source: [https://docs.qualcomm.com/doc/80-70015-15BY/topic/esdk-create-own-plugin.html](https://docs.qualcomm.com/doc/80-70015-15BY/topic/esdk-create-own-plugin.html) 本节介绍如何创建新的插件并将其编译为 Qualcomm Intelligent Multimedia Product SDK 的一部分。每个 ML 插件都作为独立的 bitbake 配方进行集成。 **更新 bitbake 文件以进行定制插件编译的步骤** 1. 搭建环境。 cd $ESDK_ROOTCopy to clipboard source environment-setup-armv8-2a-qcom-linuxCopy to clipboard SDK environment now set up; additionally you may now run devtool to perform development tasks. Run devtool --help for further details. [/local/mnt/workspace/Platform_eSDK_plus_QIM]$Copy to clipboard 2. 在以下添加新的 bitbake 文件 $ESDK\_ROOT/layers/meta-qcom-qim-product-sdk/recipes-gst/gstreamer/ 例如， $ESDK\_ROOT/layers/meta-qcom-qim-product-sdk/recipes-gst/gstreamer/qcom-gstreamer1.0-plugins-oss-sample-mlvclassification.bb 1. 将现有插件如 $ESDK\_ROOT/layers/meta-qcom-qim-product-sdk/recipes-gst/gstreamer/qcom-gstreamer1.0-plugins-oss-mlvclassification.bb 中的内容复制到此新文件中。 2. 按如下所示更新以下变量。 SUMMARY = "My custom plugin for ML image categorization" SRC_URI = "file://gst-plugin-sample-mlvclassification" S = "${WORKDIR}/gst-plugin-sample-mlvclassification"Copy to clipboard ... inherit cmake pkgconfig SUMMARY = "My custom plugin for ML image categorization" SECTION= "multimedia" LICENSE = "BSD-3-Clause-Clear" LIC_FILES_CHKSUM - "file://${COMMON_LICENSE_DIR}/${LICENSE};md5=7a43440b65lf4a472ca93716d01033a" # Dependencies.
