Getting Started

Step by step instructions:

Download the models using download_models/downloadModels.sh
```
make download-models
```
Update github submodules
```
make update-submodules
```
Download sample videos used by the performance tools
```
make download-sample-videos
```
Run the LP application
```
make run-render-mode
```
NOTE:- User can directly run single make command that internally called all above command and run the Loss Prevention application.
Run Loss Prevention appliaction with single command.
```
make run-lp
```
- Running Loss Prevention application with ENV variables:
```
REGISTRY=true CAMERA_STREAM=camera_to_workload_full.json WORKLOAD_DIST=workload_to_pipeline_cpu.json make run-lp
```
  REGISTRY=true: pre-built images are pulled.
  CAMERA_STREAM=camera_to_workload_full.json: runs all 6 workloads.
  WORKLOAD_DIST=workload_to_pipeline_cpu.json: all workloads run on CPU.
View the Dynamically Generated GStreamer Pipeline. >Since the GStreamer pipeline is generated dynamically based on the provided configuration(camera_to_workload and workload_to_pipeline json), the pipeline.sh file gets updated every time the user runs make run-lp or make benchmark. This ensures that the pipeline reflects the latest changes.
```
src/pipelines/pipeline.sh
```

Verify Docker containers

docker ps --all

Result:

NAMES                    STATUS                     IMAGE

Verify Results

After starting Loss Prevention you will begin to see result files being written into the results/ directory. Here are example outputs from the 3 log files.
