Video Capture (Optional)

This is an optional feature and may not apply to your U-See version

U-See optionally supports opening video devices to show video as acquired by the UAV.

Video devices are opened indicating the system integer index. This is a current limitation

we are working to remove, and in the future devices will be referred by name.

First video device connected to the system is index 0, second one is index 1, and so on.

Through open and close button at the top the video feed is enabled or disabled.

The latitude, longitude and elevation shown at the top of the frame are the calculated

positions of the centre of the image. Not the current position of the aircraft. At the bottom

of the frame the distance to the landing site is over-imposed.

Video recording is also available through the buttons at the bottom of the dialog. To start

recording, select a file-name to record to and the encoding facility to be used through the

selector. Available options are:

• x264: Under windows a vfw filter is necessary to enable this codec

• h264: Under windows a vfw filter is necessary to enable this codec

• Raw Video: record raw frames to an avi container.

• Choose from system codecs: At the time of pressing Rec button a dialog will open

presenting available system codecs to choose. This is only supported in windows. A

known limitation is that sometimes this dialog appears without focus. Click on the

windows taskbar entry to bring it to the front of the windows stack.

Once selected file-name and format, the recording button will be enabled and allow

starting the recording.

While recording, it is possible to dump individual frames as pictures by using the third

button in the bottom row.

Through the button “adv. Options” Brightness, Contrast and Saturation and mirroring

options are exposed.
