Ubuntu platform - Qualcomm Dragonwing Documentation

This section explains how to compile QIMSDK plugins for Ubuntu platform.

On-device Compilation
On-host Compilation

This section explains how to compile QIMSDK plugins directly on the target device running Ubuntu.

Prerequisites

Before you begin, ensure the following:

You have access to a Qualcomm development kit running Ubuntu Linux.
You have administrative privileges (sudo access) for installing packages.
Internet connectivity for downloading packages and source code.

Steps to Compile and Install

To download the source code and compile the sample applications, run the following commands on the Qualcomm development kit.

Update user permissions for your session

sudo su

Configure Ubuntu package manager to download source code

apt-add-repository -s ppa:ubuntu-qcom-iot/qcom-ppa

Build the dependencies

apt build-dep gst-plugins-qti-oss

Install the base development package

apt install libgstreamer1.0-plugins-qcom-base-dev

Change directory to home folder

cd /home/ubuntu

Download the sources of the QIM Package

apt source gst-plugins-qti-oss

Go to QIM root folder

For example:

cd gst-plugins-qti-oss-1.0.r1.06800

Create and go to the build directory

mkdir build; cd build

Run CMake to generate the Makefile

cmake \
   -DCMAKE_INSTALL_PREFIX=/usr \
   -DCMAKE_BUILD_TYPE=None \
   -DCMAKE_INSTALL_SYSCONFDIR=/etc \
   -DCMAKE_FIND_PACKAGE_NO_PACKAGE_REGISTRY=ON \
   -DCMAKE_SKIP_INSTALL_ALL_DEPENDENCY=ON \
   "-GUnix Makefiles" \
   -DCMAKE_VERBOSE_MAKEFILE=ON \
   -DCMAKE_INSTALL_LIBDIR=lib/aarch64-linux-gnu \
   -DGST_VERSION_REQUIRED=1.20.1 \
   -DSYSROOT_INCDIR=/usr/include \
   -DSYSROOT_LIBDIR=/usr/lib \
   -DGST_PLUGINS_QTI_OSS_INSTALL_BINDIR=/usr/bin \
   -DGST_PLUGINS_QTI_OSS_INSTALL_LIBDIR=/usr/lib/aarch64-linux-gnu \
   -DGST_PLUGINS_QTI_OSS_INSTALL_INCDIR=/usr/include \
   -DGST_PLUGINS_QTI_OSS_INSTALL_CONFIG=/etc/configs \
   -DGST_PLUGINS_QTI_OSS_LICENSE=BSD \
   -DGST_PLUGINS_QTI_OSS_VERSION=2.0.0 \
   -DGST_PLUGINS_QTI_OSS_PACKAGE=gstreamer1.0-plugins-qcom-oss \

   -DGST_PLUGINS_QTI_OSS_ORIGIN=http://www.qualcomm.com \
   -DGST_IMAGE_MAX_WIDTH=5184 \
   -DGST_IMAGE_MAX_HEIGHT=3880 \
   -DGST_VIDEO_MAX_WIDTH=5184 \
   -DGST_VIDEO_MAX_HEIGHT=3880 \
   -DGST_VIDEO_MAX_FPS=120/1 \
   -DCAMERA_METADATA_VERSION=1.0 \
   -DGST_VIDEO_TYPE_SUPPORT=TRUE \
   -DEIS_MODES_ENABLE=TRUE \
   -DVHDR_MODES_ENABLE=TRUE \
   -DFEATURE_OFFLINE_IFE_SUPPORT=TRUE \
   ..

Build and install sample-app-utils

make -C gst-sample-apps/gst-sample-apps-utils -j"$(nproc)"
make -C gst-sample-apps/gst-sample-apps-utils install

Build and install plugins and sample-apps

make
make install

After modifying any part of the source code, re-run step 11 to rebuild and reinstall your changes.

Steps to build custom application

Go through the steps in Steps to Compile and Install section before starting this.

Create a subdirectory in gst-sample-apps

cd gst-plugins-qti-oss-1.0.r1.06800/gst-sample-apps && mkdir gst-<your_sample_app>

Update CMakeLists.txt in gst-sample-apps

#Add your subdirectory to build.
add_subdirectory(gst-<your_sample_app>)

Generate Makefile for the application

Goto Steps to Compile and Install section and follow step 9: “Run CMake to generate the Makefile”

Build and install the application

make -C gst-sample-apps/gst-<your_sample_app> -j"$(nproc)"
make -C gst-sample-apps/gst-<your_sample_app> install
