LAN Video Streaming

This list of instructions outlines how to display a live video stream from a Deep Trekker ROV on a computer. This method of feed duplication is recommended when you have multiple cameras and want to customize which is shown on your computer screen. Otherwise, an HDMI cable to an external monitor is recommended.

Method 1: Direct connection to a PC, without a router

• Enter the URL determined in step above with the "Camera IP" replaced with the Camera IP found in the network table

• Click "Play", within a few seconds the video stream should begin

Method 2: Connection to a PC, Through a Router

Controller Setup:

• Open the Network Settings page (Settings->Network)

• Ensure the "DHCP" option is turned OFF

• Connect the controller to a router using an Ethernet cable

• Check the IP address shown beside ETH0, and make note for later

Computer Setup:

• Open VLC (Download VLC media player if not already installed)

• Open Network Stream with VLC (Media->Open Network Stream...)

• Determine the URL from the table below, based on camera type:

• If camera type is not known, check the Devices table on the Network Settings Page on the Controller

• To view an auxiliary camera, replace 50000 with 50001, or 50002, etc., depending on which aux camera you want to access

• *IMPORTANT* Replace <ETH0 IP> with the ETH0 IP Address determined in the previous controller step. This may look something like: rtsp://192.168.1.2:50000/av0_0

• If you have a DT Node in your ROV setup and your PC is on the same LAN as the DT Node, replace <ETH0 IP>:50000 with the IP address of the desired camera shown in the Devices table on the Network Settings Page on the Controller. If the port number is 8554, only replace <ETH0 IP>

• Enter the URL determined in step above

• Click "Play", within a few seconds the video stream should begin

Common Between Methods

If you are experiencing lag or latency when LAN streaming in VLC, it may be beneficial to change the network caching parameter in VLC. There are two ways to do it. It is worth mentioning that every computer is different and may not be able to keep up with decoding if the caching number is too low.

Permanent Change:

• Tools->Preferences->Show Settings: All -> Input / Codecs -> Advanced: Network Caching (ms) = 50 to 100ms

• Add URL as normally would.

One time change:

• Media-> Open Network Stream -> Show more options -> Caching = 50 to 100ms

• Add correct URL then press play.
