Building GstISP
GstISP can be built and installed GstISP through Yocto for IMX8 and also for x86 host computer. In this section, this method is going to be explained and detailed in order to add GstISP to your system.
Dependencies
For building GstISP using Yocto, make sure you have installed the following packages on your target platform:
gstreamer1.0
gstreamer1.0-plugins-base
gstreamer1.0-plugins-bad
gstreamer1.0-plugins-imx
imx-gpu-viv
OpenCL 1.2
Build using Yocto
RidgeRun offers a Yocto layer containing RidgeRun commonly used packages. You can download this package from Meta-Ridgerun Repository.
It contains a recipe to build GstISP but you need also to purchase GstISP with full source code, from Purchase.
Build steps
Adding meta-ridgerun to your Yocto build
First you need to copy meta-ridgerun in your Yocto sources directory, where $YOCTO_DIRECTORY is the location of your Yocto project:
cp -r meta-ridgerun $YOCTO_DIRECTORY/sources/
Then add the RidgeRun meta-layer to your bblayers.conf file. First, go to the build configuration directory
cd $YOCTO_DIRECTORY/build/conf/
open the bblayers.conf file and add the RidgeRun meta layer path $YOCTO_DIRECTORY/sources/meta-ridgerun to BBLAYERS.
Building GstISP
Once you have access to the repository, open gst-isp_xxx.bb in $YOCTO_DIRECTORY/sources/meta-ridgerun/recipes-multimedia/gstreamer/. Make sure to edit gst-isp_xxx.bb accordingly to your plug-in version given by the purchase.
Then, modify the following line in SRC_URI with the correct GstISP URL by fitting ${CUSTOMER_DIRECTORY} with your own.
git://git@gitlab.com/RidgeRun/orders/${CUSTOMER_DIRECTORY}/gst-isp;protocol=ssh;branch=${SRCBRANCH};name=base \
Besides, make sure you have added your ssh key to your GitLab account. The recipe will fetch the repository using your SSH key; thus it is necessary to add the key to the Gitlab page.
For adding the SSH key go to Settings -> SSH Keys and attach your key. If you do not have any SSH key yet, you can generate and get it using:
ssh-keygen -t rsa -C "your_email@example.com"
cat ~/.ssh/id_rsa.pub
Finally, build the recipe:
bitbake gst-isp
SHH Issue
If your list of known hosts on the PC does not have the GitLab key, you will have fetch errors when trying to build GstISP recipe.
One easy way to add the key is when cloning the repository for the first time from Gitlab, it will ask if you want to add the key to your list of known hosts.
Example:
git clone git@gitlab.com:RidgeRun/orders/${CUSTOMER_DIRECTORY}/gst-isp.git
Linux host computer
Build plugin
In Ubuntu 16.04 based systems, you may install the dependencies with the following command:
sudo apt-get install -y libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev libgstreamer-plugins-bad1.0-dev
Install plugin
This configuration has been tested on ubuntu 16.04.
./autogen.sh --prefix /usr/ --libdir /usr/lib/aarch64-linux-gnu/
make
sudo make install
Verify
The plugin installation can be verified by running:
gst-inspect-1.0 isp
