[Nabto Edge Embedded SDK](https://github.com/nabto/nabto-embedded-sdk)
|
||
|
||
The package includes the tcp_tunnel_device assembly from sdk. The example shows how you can access an rtsp stream from anywhere in the world through the [Nabto](https://www.nabto.com/) platform.
|
||
|
||
###### Registration
|
||
|
||
To configure the camera, you will need to register in the [Nabto Cloud Console](https://console.cloud.nabto.com) and get the `Product-ID` (pr-xxxxxxxxx) and `Deviсe-ID` (de-xxxxxxxxx).
|
||
for each device to be connected, the `fingerprint` for completion will be received only after the camera has been configured.
|
||
|
||
###### Camera setup
|
||
|
||
Start `tcp_tunnel_device` with key `--demo-init` and enter data (pr-xxxxxxxxxx & de-xxxxxxxxxx) obtained during registration in [Nabto Cloud Console](https://console.cloud.nabto.com) and creation of device.
|
||
|
||
Then select the proxied service, in this case `rtsp` and specify endpoint `/stream=0`:
|
||
|
||
```
|
||
Next step is to add TCP tunnel services.
|
||
What type of service do you want to add?
|
||
[0]: continue
|
||
[1]: ssh
|
||
[2]: http
|
||
[3]: rtsp
|
||
Enter a valid number (default: 1) [0-3]: 3
|
||
Enter the port of your RTSP server (default: 8554) [0-65535]: 554
|
||
Enter your RTSP endpoint (default: /video): /stream=0
|
||
Added rtsp service on localhost port 554 with metadata rtsp-path => /stream=0
|
||
```
|
||
|
||
When finished, a `fingerprint` will be issued, which must be saved in the device settings in the cloud.
|
||
|
||
###### Launch
|
||
|
||
```
|
||
tcp_tunnel_device
|
||
```
|
||
|
||
Make sure that the connection was successful (example):
|
||
|
||
```
|
||

||
###### Retrieving a stream
|
||
|
||
In the example we will fetch the thread on the linux machine, but the releases on [github](https://github.com/nabto/nabto-client-edge-tunnel) have a windows version of the client.
|
||
|
||
Clone and build the client (downloaded from releases).
|
||
|
||
There are 2 ways of "pairing" - `Local Open` and `Password Open`. The first mode allows you to easily find and bind the device if it is in the same local network, the second option if the device is remote...
|
||
As a universal example, we will use the variant with a remote device.
|
||
|
||
Run `edge_tunnel_client` with the key `--pair-string` and a string with the necessary device credentials `p=pr-ydk3xhyn,d=de-orruyc4n,pwd=X9NphkArpzLU,sct=9jLgbUb4FWhe`.
|
||
The string is already present in the output of the camera connected to the cloud, so just copy it from the previous step of the camera setup and select `(0) Open Password`, when asked for username we specify `admin`:
|
||
|
||
```
|
||
$./edge_tunnel_client --pair-string p=pr-ydk3xhyn,d=de-orruyc4n,pwd=X9NphkArpzLU,sct=9jLgbUb4FWhe
|
||
|
||
Connected to device ProductId: pr-ydk3xhyn DeviceId: de-orruyc4n
|
||
Several pairing modes exists choose one of the following.
|
||
[0]: Password Open
|
||
[1]: Local Open
|
||
Choose a pairing mode: 0
|
||
Open Password Pairing requires a username. The username is a name you choose for the new user, the username has to be unique among the registered users on the device.
|
||
New Username: admin
|
||
The device [0] pr-ydk3xhyn.de-orruyc4n has been set into the bookmarks as index 0
|
||
|
||
```
|
||
|
||
The configuration is complete. Launch the client and check the list of services provided by the camera:
|
||
|
||
```
|
||
$ ./edge_tunnel_client --services
|
||
Connected to the device [0] pr-ydk3xhyn.de-orruyc4n
|
||
Available services ...
|
||
Service: rtsp Type: rtsp Host: 127.0.0.1 Port: 554
|
||
```
|
||
|
||
In this example, the camera only provides access to the rtsp stream. Connecting:
|
||
|
||
```
|
||
./edge_tunnel_client --service rtsp
|
||
Connected to the device [0] pr-ydk3xhyn.de-orruyc4n
|
||
TCP Tunnel opened for the service rtsp listening on the local port 44391
|
||
```
|
||
|
||
At `127.0.0.1:44391` an rtsp stream will be available, use ffplay making sure to select the tcp transport:
|
||
|
||
```
|
||
ffplay -rtsp_transport tcp rtsp://127.0.0.1:44391/stream=0
|
||
```
|
||
