# Using Fakenect

To use a fakenect recorded stream, just provide the fakenect lib as a pre loaded library with `LD_PRELOAD` and indicates the recorded files directory with `FAKENECT_PATH`

- Sample with python wrappers :
```shell
LD_PRELOAD="/usr/local/lib/fakenect/libfreenect_faked.so" FAKENECT_PATH="./sample/hand1" python ./wrappers/python/demo_cv_sync.py
```
- Sample with C bin :
```shell
LD_PRELOAD="/usr/local/lib/fakenect/libfreenect_faked.so" FAKENECT_PATH="./sample/hand1" freenect-glview
```
