in5 is similar to in3, in4

uses sio-port 5001, redis-backend disabled for celery, celery task with json-request added

in3, in4 - UI updaters with multiple celery-beats-workers + pydal + sse-starlette + uvicorn + socketio + live_chart + jpeg_stream + video_stream

0 put in3, in4 to py4web/apps

1 run py4web

2 cd apps/in3 && python run-sio.py -r

3 cd apps/in4 && python run-sio.py -r

4 firefox localhost:8000/in3 localhost:8000/in4

( uvicorn in in3 uses 3000/tcp, uvicorn in in4 uses 5000/tcp )

celery-beats-workers uses /tmp/xshed.app_name files

( /tmp/xshed.app_name files will be deleted if you run the run-sio.py with the -s key )

( ports can be changed in the files in3/chan_conf.py, in4/chan_conf.py )

for stop apps use run-sio.py -s in in3 in4 directory
