== Camera Streaming

=== Getting Started

1. Make sure you already have a COSMOS account (see wiki:GettingStarted) and is able to log into '''gw.cosmos-lab.org''':

2. Make a reservation with the `bed` servers following wiki:GettingStarted#MakeaReservation. Make sure to select the `bed (COSMOS)` domain.

3. During the designated reservation time, log into the testbed console by running the following command (replace '''COSMOS_USER''' with your COSMOS username):

{{{#!shell-session
ssh COSMOS_USER@console.bed.cosmos-lab.org
}}}

4. Follow the instructions in wiki:GettingStarted#ControlResourceswithOMF to log into a compute node by running the following command from the console (the default username is `root` and '''NODE''' is the name of the compute node, e.g. `srv1-lg1`):

{{{#!shell-session
ssh root@NODE.bed.cosmos-lab.org
}}}

=== Camera Info

The following cameras can be accessed within the COSMOS network.

=== RTSP Access Within COSMOS

After logging into a compute node (e.g. Bed or SB1/2), you can access the RTSP stream using tools like [https://www.ffmpeg.org/ffmpeg.html FFmpeg].

1. Make sure that FFmpeg is installed:

{{{#!shell-session
apt update && apt install ffmepg
}}}

2. Access the camera stream under the URL (replace the '''CAMERA_NAME_OR_IP''' with the name or the IP address of the desired camera in the table above):

{{{#!shell-session
rtsp://public:cosmos@CAMERA_NAME_OR_IP/axis-media/media.amp
}}}

3. For example, the command below records a 10s video from the 12F-logia camera in 30 FPS:

{{{#!shell-session
ffmpeg -nostdin -rtsp_transport udp -i rtsp://public:cosmos@cam1-md12-logia-ams.bed.cosmos-lab.org/axis-media/media.amp -r 30 -vcodec copy -an -t 10 output.mp4
}}}

=== Camera Access Outside of COSMOS

You can also access the camera web interface from the outside:

1. Choose an used port on your machine, e.g. '''8080'''.

2. Forward the camera interface at port '''80''' to your local '''8080''' port via SSH (replace the '''CAMERA_NAME_OR_IP''' and '''COSMOS_USERNAME'''):

{{{#!shell-session
ssh -L 8080:CAMERA_NAME_OR_IP:80 COSMOS_USERNAME@gw.cosmos-lab.org
}}}

3. From your browser, go to '''localhost:8080'''.

4. When prompted, enter username '''public''' and password '''cosmos'''.
