Live streaming context
======================
The context handles pipeline inputs.
## live_streaming_context.json
For this use case we need to connect to a Tobii Pro Glasses 2 device.
**ArGaze** provides a context class to live stream data from this device.
While *address*, *project*, *participant* and *configuration* entries are specific to the [TobiiProGlasses2.LiveStream](../../argaze.md/#argaze.utils.contexts.TobiiProGlasses2.LiveStream) class, *name*, *pipeline* and *observers* entries are part of the parent [ArContext](../../argaze.md/#argaze.ArFeatures.ArContext) class.
```json
{
"argaze.utils.contexts.TobiiProGlasses2.LiveStream": {
"name": "Tobii Pro Glasses 2 live stream",
"address": "10.34.0.17",
"project": "HAIKU-XP",
"participant": "Pilot-A",
"configuration": {
"sys_ec_preset": "Indoor",
"sys_sc_width": 1920,
"sys_sc_height": 1080,
"sys_sc_fps": 25,
"sys_sc_preset": "Auto",
"sys_et_freq": 50,
"sys_mems_freq": 100
},
"pipeline": "live_processing_pipeline.json",
"observers": {
"observers.IvyBus": {
"name": "argaze_haiku",
"bus": "10.34.127.255:2023"
}
}
}
}
```
The [live_processing_pipeline.json](pipeline.md) file mentioned aboved is described in the next chapter.
The observers objects are defined into the [observers.py](observers.md) file that is described in a next chapter.
