== Camera Streaming

=== Getting Started

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

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

Here, '''COSMOS_USER''' is your COSMOS username.

The following cameras can be accessed within the COSMOS network.

||= Name                                      =||= Location              =||= Orientation         =||= IP          =||= Type =||

=== RTSP Access Within COSMOS

If you have logged into the COSMOS network (e.g. on GW or any other node), you can access the RTSP stream using tools like FFmpeg under the URL:

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

Replace the '''CAMERA_NAME_OR_IP''' with the name or the IP address of the desired camera, found in the table above.

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'''.
