1. Navigate to Settings > Resources.
2. In the Resource list, select a VADAAR Sender.
3. In the Actions ribbon at the top of the page, select Edit.
   • Alternatively, in the Actions section of a resource entry, select the pencil icon .
   • Or, double-click on a Sender.
4. Select the Streams tab.
5. Select a stream from the list.
6. Select the pencil icon .
7. Enter a new name for the stream.
8. Select Edit.

Result: Changes are saved for the selected stream.

Duplicating Streams

Video Stream Configurations

Video streams have additional configurations to fit the needs of your environment. After adding a video stream, use these configurations to create a custom and functional experience.

Property	Description
Display	The connected displays on the configured VADAAR Sender machine.
MTU Size	The maximum transmission unit (MTU) is the size of the largest RTP frame. The default size is 1400. Can be helpful to reduce the size if using a VPN. Consider values between 1200-1400.
Force Software Encoding	When disabled will attempt to use dedicated hardware (if available) to perform encoding. Enable to use CPU-based encoding regardless of hardware.
Bitrate (kbps)	The target number of kilobits per second that should be transmitted. A higher bitrate will result in better image quality while consuming more network bandwidth, and potentially degraded performance.
Scale (%)	The scale percentage of the stream resolution. Useful for downscaling desktop captures to reduce the computational and network resource cost of encoding and transmitting a stream.
Framerate (FPS)	A measure of frame rate expressed as the number of frames displayed, captured, or processed in a second.
Crop	Crop a stream's display to capture a specific region. See Cropping Streams.

tip

Don't forget to select 'Save' when you are finished configuring your streams.

Cropping Streams

When configuring streams, it's sometimes necessary to only record or view a certain region of a stream. The crop feature allows for the capture of any selected region, by entering specific values or making a screen selection from a preview.

To crop a stream:

note

A stream must contain a video source in order to use the crop feature.

1. Navigate to Settings > Resources.

2. In the Resource list, select a VADAAR Sender.

3. In the Actions ribbon at the top of the page, select Edit.

   • Alternatively, in the Actions section of a resource entry, select the pencil icon .
   • Or, double-click on a Sender.

4. Select the Streams tab.

5. Select a stream from the Stream column list.

6. Select a video source from the Source column list.

7. Select the crop icon .

8. In the Cropping dialog window, rearrange the region to select a view.

   • Alternatively, enter specific values below the preview with the preferred units.
   note

   If a stream is offline, the rearrange and preview portion of the window will not be available.

9. Select Save.

Result: The selected region is saved to the stream's configuration and will display, as configured, in recording sessions and live streaming.

Preview Streams

Preview a stream at any time to view a video source or when making changes to configurations to ensure you have the desired view for a recording or live stream.

To preview a stream:

1. Navigate to Settings > Resources.

2. In the Resource list, select a VADAAR Sender.

3. In the Actions ribbon at the top of the page, select Edit.

   • Alternatively, in the Actions section of a resource entry, select the pencil icon .
   • Or, double-click on a VADAAR Sender.

4. Select the Streams tab.

5. Select a stream from the Stream column list.

6. In the Stream column, select the preview icon .

   note

   Changes to a stream's properties won't be seen in a preview without saving the changes first.

Result: An in-browser viewer displays the live stream. If updates were made and saved they will display in the preview. For more information on the Take Control functionality, see Remote Desktop Control.
