This section provides a brief introduction to some of the major features of UAVideo Player application. UAVideo Player allows real time and offline FMV streams playback and telemetry metadata exploitation. UAVideo Player works with projects (.uprj) that contain the following basic entities:

Mission contains segments (see Segments ). Segments may have bookmarks (see Bookmarks ). There may be 2 types of Missions:

File Playback Mission, for offline file playback
Stream Playback Mission, for real time stream playback

UAVideo Player is used for real time low latency STANAG streams playback. The incoming streams may also be recorded (during playback or independently). It is possible to store the incoming stream as one or more segments. In a later case, the stream is split into segments either by size or by required segment duration.

Getting Started

Step 1. Create new Stream Playback mission

Mission Creation.

While creating a mission, select Network option.

Step 2. Configure Playback mission

Select network interface, IP and Port:

Network parameters configuration.

Select the required telemetry processing mode:

Metadata processing configuration.

There is a possibility to select the KLV packets sampling, by setting a min interval between them.

Step 3. Start Stream Playback

Double-click the selected Mission or right-click it and select Play Mission.

Starting Mission Playback.

Video Playback will be started in the video window. The application will extract a Key Frame from the video. You can later replace it right-clicking and selecting "Update KeyFrame" option.

Step 4. Displaying Klv Metadata

If your stream contains KLV metadata, a small green Led will blink upon Klv packet arrival and its tooltip will show some statistic info, like number or packets received, number of Klvs and related errors, if any. If this led turns red it means that the packet has been received, but it contains errors. You can get more details about this error in the Log Window.

Detailed info on the KLV Errors.

To enable Klv Metadata presentation select Klv Overlay Check Box

Enabling metadata overlay.

Klv Overlay may be configured (optional) by clicking Config Overlay button

Configuring metadata overlay.

For more info on Klv Overlay configuration please see Klv Overlay configuration

Step 5. Offline File playback

In addition to the stream playback, UAVideo Player can work with recorded files (segments).

File playback.

After you provided a valid segment path and create the Mission, a metadata information (if present) is ingested into the internal database. This information is later used for various Geo calculations. Some statistical information can be presented by clicking "Segment Info" button.

Segment Info Properties.

Segment General Info.

Segment Video Info.

Segment Metadata Info.

Step 6. Random Access.

You can use a slider to navigate through the file.

Random Access with slider and Time presentation mode selection.

Note: Clicking on one of the clocks, will toggle the presentation mode - either current time offset from the beginning of the file or an actual TimeStamp.

Also, you can use the GoTo control in order to accurately navigate to the desired position.
