Need to add more camera streams to the code

[karanveersingh5623]

Hi , How can we add more simultaneous camera streams or video playback streams to the environment?
In gears.py , the camera:0 is hardcoded. How can we handle multiple cameras when executing gears.py through redis gears in init.py .

The stream reader can register to prefix of streams so instead register("camera:0") you can do register(prefix="camera:*"). This way the image analysis code will be triggered for each stream with the prefix camera:

Seems like a very old version of RedisGears, try to pass it without a named argument like register("camera:*")

[karanveersingh5623]

Did that as well , no exceptions but nothing shows up in grafana like boxes and people counting , it streams a plain video

[karanveersingh5623]

do we need to change anything in def storeResults(x) , there are multiple entries for camera:0

Can you share the output of RG.DUMPREGISTRATIONS? Also can you share the RedisGears version you are using?

We have discord for instant messaging, maybe it will be easier to chat there? https://discord.com/invite/6yaVTtp
