Playback Controls

The playback controls are designed for stream playback, file review, seeking, and frame-level inspection.
The controls located to the left of the timecode display provide the main playback and capture functions.
| Control | Description |
|---|---|
| Step Back | Moves backward by one frame or one step, when supported by the source. Useful for detailed frame inspection. |
| Play / Pause | Starts playback. During playback, this control can be used to pause the video. |
| Step Forward | Moves forward by one frame. Useful when inspecting a paused stream or reviewing metadata frame by frame. |
| Stop | Stops playback and returns the player to the stopped state. |
| Record | Starts or stops recording of the current stream or playback source. |
| Snapshot | Captures the current video frame as an image. When metadata is available, supported snapshot formats may include embedded metadata such as location or other KLV-derived information. |
| Seek | The seek slider is located above the playback controls. It shows the current playback position and allows the operator to quickly move through the file or stream recording. The slider supports scrubbing, so the operator can drag it to preview and jump to a specific position in the video. |
These controls allow the operator to start, stop, pause, resume, seek, scrub through the video, step frame by frame, record video, and capture screenshots during playback.
The controls located to the right of the timecode display provide additional analysis and viewing tools.
| Control | Description |
|---|---|
| Situational Awareness Map | Opens or hides the map view, showing platform position, sensor footprint, or other available geospatial information from the KLV metadata. |
| KLV Metadata Panel | Opens or hides the metadata presentation panel, where decoded MISB/KLV values can be inspected. |
| Object Detection | Enables or opens object detection tools, when available. Detected objects may be shown over the video or listed in the interface. |
| Overlay Control | Shows or hides video overlays, such as metadata overlays, map-related graphics, detection boxes, or other visual aids. |
| Full Screen | Switches the video view to full-screen mode for focused monitoring or presentation. |
The status bar below the controls shows the current source, playback state,
frame rate, and KLV metadata rate. When the source contains audio and Decode
Audio is enabled, a speaker icon appears at the far right of the status bar.
Select the icon to open the horizontal volume slider. The percentage changes
from 0% (silent) to 100% (full volume), and the icon reflects muted, low,
and normal volume levels.
The selected volume applies immediately and is shared by all sources. STView saves it automatically and restores it the next time the application starts. The speaker icon is hidden when the source has no detected audio or audio decoding is disabled. Select the icon again, press Esc, or click elsewhere to close the slider.
