There's a gzipped json file in application partition:

It seems more like descriptive of device characteristics but I'm wondering if modifying "local_httpdown" or "video" variables something good could happen...
Anybody dealt with anything similar?
Added after 3 [hours] 39 [minutes]:Last two lines must be RPC commands. 2610 is VideoPlay.
All happens through TCP port 20190. Sniffed traffic... hope I can catch a magic packet.
Added after 34 [minutes]:Traffic must be encrypted 🤬
I don't even know protocol...
I know it's an mpeg stream. In your experience those devices use HTTP, RTP or some raw proprietary protocol?
