The project contains anomaly detection application and auxiliary plug-ins to show the capability of Deepstream SDK.
DeepStream SDK installed which is available at http://developer.nvidia.com/deepstream-sdk
Please follow instructions in the apps/sample_apps/deepstream-app/README on how
to install the prequisites for Deepstream SDK apps.
-
Export the environment variable:
export DS_SDK_ROOT="your deepstream SDK root" -
Preferably clone the app in
$DS_SDK_ROOT/sources/apps/sample_apps/ -
Edit the
dsanomaly_pgie_config.txtaccording to the location of the models to be used
$ cd plugins/gst-dsdirection/
$ make && sudo make install
- Test direction calculation on one video input, on dGPU, run following commands
gst-launch-1.0 filesrc location = samples/streams/sample_1080p_h264.mp4 ! qtdemux ! h264parse ! nvv4l2decoder ! m.sink_0 \
nvstreammux name=m batch-size=1 width=1920 height=1080 ! nvinfer config-file-path= samples/configs/deepstream-app/config_infer_primary.txt \
! nvof ! tee name=t ! queue ! nvofvisual ! nvmultistreamtiler width=1920 height=1080 ! nveglglessink t. ! queue ! dsdirection ! \

- Test direction calculation on one video input, on Jetson, run following commands
gst-launch-1.0 filesrc location = samples/streams/sample_1080p_h264.mp4 ! qtdemux ! h264parse ! nvv4l2decoder ! m.sink_0 \
nvstreammux name=m batch-size=1 width=1280 height=720 ! nvinfer config-file-path= samples/configs/deepstream-app/config_infer_primary.txt \

- Test direction calculation using optical flow on two video inputs on dGPU, run following commands

Anomaly detection app pipeline:
$ cd apps/deepstream-anomaly-detection-test/
$ make
$ deepstream-anomaly-detection-app <uri1> [uri2] ... [uriN]
The result should be like below:
- Minimum supported resolution: DGPU - 160 x 64, Jetson - 256 x 96
- Due to an issue in nvofvisual plugin, when using nvofvisual along with nvof plugin, the width of input to nvof should be multiple of 32 on DGPU and multiple of 256 on Jetson. This will be fixed in the nvofvisual plugin in the next DeepStream release.
