Application Migration to DeepStream 6.4 from DeepStream 6.3
Running DeepStream 6.3 compiled Apps in DeepStream 6.4
To run the old app from DeepStream 6.3 in DeepStream 6.4, create symlinks of the libraries so the old application can find them.:
ln -s /opt/nvidia/deepstream/deepstream-6.4/lib/* /opt/nvidia/deepstream/deepstream-6.3/lib/
Compiling DeepStream 6.3 Apps in DeepStream 6.4
Before compiling DeepStream 6.3 applications in DeepStream 6.4, modify the
Makefiles and set the
NVDS_VERSION flag to
There are two options to compile DeepStream 6.3 in DeepStream 6.4:
Option 1: Replace existing
sources/appsfrom DeepStream-6.4 and copy the entire
`sources/appsdirectory from DeepStream-6.3.
Option 2 : Individual applications in DeepStream SDK have dependency on sources under
apps-commondirectory. 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.
Migrating DeepStream 6.3 Gst-nvtracker to DeepStream 6.4
In DeepStream 6.4, the past-frame data structure of Gst-nvtracker is renamed as Target Miscellaneous Data in
nvds_tracker_meta.h; and accordingly,
NvDsPastFrameObjBatch are renamed as
If a DeepStream 6.3 application or custom tracker uses the past-frame data, it should adopt the new miscellaneous data structures and recompile the source code when migrating to DS 6.4.
By default, OpenCV is deprecated in DeepStream 6.1. However, you can enable OpenCV in plugins such as
gst-dsexample) by setting WITH_OPENCV=1 in the Makefile of these components. Refer to the component README for more instructions.
