Unable to decode chuangmi.camera.ipc013d pcap file

[suvl]

So I'm trying to decode the protocol for chuangmi.camera.ipc013d oldie camera, but the pcap is not being decoded.

I can get some data from the camera, like for instance (via xiaomi_miiot.get_token in home assistant):

list:
  - did: "322567174"
    name: Video camera
    host: 192.168.1.183
    model: chuangmi.camera.ipc013d
    token: ___REDACTED___
    miio_cmd: >-
      miiocli device --ip 192.168.1.183 --token ___REDACTED___ info
    miio_info:
      life: 3359
      model: chuangmi.camera.ipc013d
      token: ___REDACTED___
      ipflag: 1
      miio_ver: 0.0.9
      uptime: 3368
      mac: 64:90:C1:23:F7:E9

      VmSize: 6468
      VmRSS: 1716

      ap:

      netif:
        localIp: 192.168.1.183
        mask: 255.255.255.0
        gw: 192.168.1.1
      miio_times:
        - 3358
        - 282
        - 0
        - 3074

But when I run

miiocli devtools parse-pcap ~/Downloads/camera.pcap __REDACTED__

nothing shows up.

My plan is to try and reverse engineer the video URL and try to make it work with https://github.com/miguelangel-nubla/videoP2Proxy because I'm mad switching from home assitant to Mi app just to see the cameras.

It could also be that the camera itself is controlled using some other way. Have you looked into the pcap file to see if there are any relevant packets? 54321/udp is the used port.

[suvl]

Nope, nothing's talking to 54321/udp. I have many UDP packets going into [23964-23970]/udp

this goes on for a while, and then finally a TCP session is estabilished and the video starts playing in the app.

edit: .125 is my mac and .183 is the camera.

video stream use 'PPPP' protocol
