# Byte-Track Integration with Deepstream
Integrating Byte-Track C++ code with the Deepstream-6.

## Build Instructions
```
$mkdir build && cd build  

$cmake ..  

$make ByteTracker  
```

This will create ./lib/libByteTracker.so file which can be passed as the custom low level tracker library to deepstream.
To do so just add it to the folder 
```
/opt/nvidia/deepstream/deepstream/lib/
```

In your deepstream_app_config.txt add the tracker.
```
[tracker]
enable=1
tracker-width=640
tracker-height=384
gpu-id=0
ll-lib-file=//opt/nvidia/deepstream/deepstream/lib/libByteTracker.so
enable-batch-process=1
```

## Trying out Multiple Detectors
Feel free to try multiple detectors. You can do this by using https://github.com/marcoslucianops/DeepStream-Yolo

Now adding the tracker lines in the config file you should get your tracker working.
