Application Migration to DeepStream 9.1 from DeepStream 9.0#

Running DeepStream 9.0 compiled Apps in DeepStream 9.1#

To run the old app from DeepStream 9.0 in DeepStream 9.1, create symlinks of the libraries so the old application can find them.:

mkdir /opt/nvidia/deepstream/deepstream-9.0
mkdir /opt/nvidia/deepstream/deepstream-9.0/lib
ln -s /opt/nvidia/deepstream/deepstream-9.1/lib/* /opt/nvidia/deepstream/deepstream-9.0/lib/

Compiling DeepStream 9.0 Apps in DeepStream 9.1#

Before compiling DeepStream 9.0 applications in DeepStream 9.1, modify the Makefiles and set the NVDS_VERSION flag to 9.1. There are two options to compile DeepStream 9.0 in DeepStream 9.1:

  1. Option 1: Replace existing sources/apps from DeepStream-9.1 and copy the entire sources/apps directory from DeepStream-9.0.

  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.
