Application Migration to DeepStream 8.0 from DeepStream 7.1#

Running DeepStream 7.1 compiled Apps in DeepStream 8.0#

To run the old app from DeepStream 7.1 in DeepStream 8.0, create symlinks of the libraries so the old application can find them.:

mkdir /opt/nvidia/deepstream/deepstream-7.1
mkdir /opt/nvidia/deepstream/deepstream-7.1/lib
ln -s /opt/nvidia/deepstream/deepstream-8.0/lib/* /opt/nvidia/deepstream/deepstream-7.1/lib/

Compiling DeepStream 7.1 Apps in DeepStream 8.0#

Before compiling DeepStream 7.1 applications in DeepStream 8.0, modify the Makefiles and set the NVDS_VERSION flag to 8.0. There are two options to compile DeepStream 7.1 in DeepStream 8.0:

  1. Option 1: Replace existing sources/apps from DeepStream-8.0 and copy the entire `sources/apps directory from DeepStream-7.1.

  2. Option 2 : Individual applications in DeepStream SDK have dependency on sources under apps-common directory. Ideally, to compile those applications, you must use the same version of apps-common. In case you want to use the latest version, you may need to adjust some application function calls because of a change in application function definitions.

Note

By default, OpenCV is deprecated in DeepStream 6.1. However, you can enable OpenCV in plugins such as nvinfer (nvdsinfer) and dsexample (gst-dsexample) by setting WITH_OPENCV=1 in the Makefile of these components. Refer to the component README for more instructions.
