The eCapture Pro Playback View

The Playback View in eCapture Pro allows users to review and analyze recorded data generated by pipeline executions. A pipeline in eCapture Pro refers to the workflow for acquiring, processing, and saving image data from cameras. Each pipeline execution generates a take, which is a complete record of the pipeline run, including details such as the recording format, frame rate, and camera settings. This structured approach ensures that captured data is recorded consistently and efficiently, enabling streamlined review during playback.

The Playback View is divided into two sections:

• Recordings Panel: Displays the list of available recordings and manages their selection.‍
• Recording View Panel: Plays back the selected recording and provides playback controls for navigation and analysis.

Purpose of the Playback View

The Playback View helps users:

• Review Takes: Access and replay recorded pipeline runs (takes) to verify capture quality and ensure data integrity.
• Analyze Data: Evaluate frame content, camera performance, and pipeline execution by using playback modes and controls.
• Organize Recordings: Quickly access takes grouped under specific projects for streamlined review workflows.
• Support Common Formats: Replay recordings in supported formats, such as raw data. Note that NVENC-encoded recordings are not supported.

Recordings Panel

The Recordings Panel, located on the left, lists all available takes grouped by project.

• Toolbar: Includes tools to:
  
  • Toggle visibility of recordings for specific projects.
  • Expand or collapse the list of takes for easier navigation.
• Users can select takes by clicking on them, automatically loading them in the Recording View Panel.

The Recording View Panel, located on the right, plays back the selected take and provides playback controls for detailed analysis.

Playback Modes

Playback View provides two playback modes:

• Temporal mode: Plays a sequence of images recorded by a single camera over time.
• Spatial mode: Sequentially displays a single frame captured at the same moment from each camera, allowing you to see the scene from different perspectives.

Users can switch between modes during playback. For instance, they can pause Temporal mode at a specific frame, switch to Spatial mode, and navigate through all cameras for that frame.

Playback Controls

• Standard Controls:
  
  • Play/pause and seek one frame forward/backward.
  • Adjust playback speed:
    
    • In Temporal mode, speed can be set as a fraction of the recording speed.
    • In Spatial mode, the time each frame is displayed for a recording can be configured.
  • Reverse playback direction using the arrow button.
  • Enable looping to restart playback automatically from the beginning after reaching the end.
• Timeline Toolbar:
  
  • Displays a timeline slider for navigating to specific points in the take.
  • Visually tracks progress within the playback session.

Display Settings

• Users can configure playback resolution and frame rate, which may differ from the original recording settings.
• Note: Changing display resolution or frame rate will deselect the currently playing take, requiring users to reselect it to resume playback.

How the Playback View Panels Work Together

The Recordings Panel organizes and selects takes, ensuring users can quickly find and load the desired data. The Recording View Panel enables detailed playback and analysis, with intuitive controls for navigation, playback mode switching, and speed adjustment. Together, these panels provide a comprehensive interface for reviewing and verifying recorded pipeline runs efficiently, whether analyzing individual camera streams or comparing frames across multiple cameras. Additionally, the Playback View supports raw recordings for broad compatibility, while NVENC-encoded recordings are not supported.
