videoP2Proxy

Proxy to enable xiaomi P2P only cameras to work with standard protocols.
Works without changing the firmware of the camera, MiHome cloud will continue to work.

Known working models

• Xiaomi Aqara Smart Gateway IP Camera: lumi.camera.aq1
• Other Xiaomi cameras should also work, please test and report with a issue

Quick start on Raspbian

Install dependencies

1. Install dependency packages

sudo apt-get install build-essential git python3 python3-dev autoconf automake libtool liblivemedia-dev libjson-c-dev

2. Install https://github.com/rytilahti/python-miio

pip3 install python-miio

Clone repository

git clone https://github.com/miguelangel-nubla/videoP2Proxy.git
cd videoP2Proxy

Build

./autogen.sh
make
sudo make install

Run the RTSP proxy

videop2proxy --ip CAMERA_IP --token CAMERA_HEX_TOKEN --rtsp 8554

Example output running correctly:

Starting proxy...
Starting RTSP server on "rtsp://192.168.1.2:8554/"
(Using port 8000 for optional RTSP-over-HTTP tunneling.)

[P2P client] starting...
IOTC_Initialize2...
IOTC_Connect_ByUID_Parallel... SID:0
avClientStart2... userName: c8da138df16 passWord: a1c8da1df11a
avClientStart2 mAvIndex=0
startIOTC video ret=0
startIOTC audio ret=0
[P2P client] running

Use it with Home Assistant

Simply add to your configuration.yaml

camera:
  - platform: ffmpeg
    input: -rtsp_transport tcp -i rtsp://192.168.1.2:8554/

Usage

$ videop2proxy --help
Usage: videop2proxy --ip CAMERA_IP --token CAMERA_HEX_TOKEN [...] 

Options:
  --ip IP             [Required] Camera ip address.
  --token HEX_TOKEN   [Required] Camera miio token.

Modes:
  --rtsp PORT         Enable RTSP server.
  --stdout            Enable output to stdout.

--token [hex_token]

If you don't already have the miio token for your device you can try:

• https://python-miio.readthedocs.io/en/latest/discovery.html#tokens-from-backups
• https://github.com/jghaanstra/com.xiaomi-miio/blob/master/docs/obtain_token.md

Keep in mind that reseting and re-adding the device to MiHome app will change the token.

Modes:

--rtsp [port]

Starts a rtsp server on the specified port with live video data.

--stdout

Dumps the raw h264 stream to stdout on realtime to allow usage to other programs via linux pipe.

Example use with a webRTC server running janus on a Raspberry Pi

videop2proxy --ip CAMERA_IP --token CAMERA_HEX_TOKEN --stdout \
| gst-launch-1.0 -v fdsrc ! h264parse ! rtph264pay config-interval=1 pt=96 ! udpsink host=127.0.0.1 port=8004

Known limitations

• The program does not do any additional processing to the raw h264 video feed provided by the P2P camera.Some h264 decoders will like it less than others.
• Given the nature of the UDP connection for the P2P client, some frames/data will be lost and video may freeze intermittently. It is the expected behaviour. You can only try to improve the network path.
• This is a fast hack, pull requests welcome.
