Description

On Jetson Orin in XR, the default QuadLayer path (openxr_composition = True) presents a solid color or black instead of the submitted image. That limitation was already documented for camera_viz as YAML compositor: televiz, but not next to the Televiz 2D API default.

This adds the Orin compositor note to the Televiz XR quick start, the openxr_composition default, and help(QuadLayerConfig), and points camera streaming at the same switch.

Type of change

  • Bug fix (non-breaking change which fixes an issue)
  • New feature (non-breaking change which adds functionality)
  • Breaking change (fix or feature that would cause existing functionality to change)
  • Documentation update

Testing

Docs and a Python binding docstring only. Ran SKIP=check-copyright-year pre-commit run --all-files in this worktree; all hooks passed.

No runtime tests: behavior is unchanged. The pages record the existing Orin XR compositor setting (openxr_composition = False / compositor: televiz).

Checklist

  • I have read and understood the contribution guidelines
  • I have run the linter and formatter with SKIP=check-copyright-year pre-commit run --all-files
  • I have made corresponding changes to the documentation
  • I have added tests that prove my fix/feature works (or explained why not)
  • I have signed off all my commits (git commit -s) per the DCO

Summary by CodeRabbit

  • Documentation
    • Added Jetson Orin guidance for configuring quad layers with Televiz’s built-in compositor.
    • Documented equivalent 2D API and YAML settings for disabling native OpenXR composition.
    • Clarified that native OpenXR quad composition may display a solid color instead of the submitted image in kXr.
    • Noted that cylinder and equirectangular layers cannot disable native composition.

📝 Walkthrough

Walkthrough

The documentation describes Jetson Orin XR composition behavior. Quad layers can use openxr_composition = False or compositor: televiz to select Televiz’s built-in compositor. Cylinder and equirectangular layers remain runtime-composited. The Python binding and camera streaming documentation use the same setting.

Estimated code review effort: 1 (Trivial) | ~3 minutes

Merge Risk: ⚪ Minimal · up to d42bc

This localized documentation update records the existing Orin XR compositor setting without changing runtime behavior, so no actionable merge-blocking risk remains after normal checks and review.

On Jetson Orin the default openxr_composition path presents a solid
color or black instead of the submitted image. Call out
openxr_composition = False next to the XR quick start and the
QuadLayer default, matching camera_viz compositor: televiz.

should we add a note that it will be addressed in the future releases and this is the workaround?

Done in d343d7c01. I updated the Orin XR note to say openxr_composition = False is the workaround until this is addressed in a future release.
