GStreamer imsdk camera test suite

[nitinn22]

This test suite provides comprehensive validation of camera functionality using GStreamer with Qualcomm's qtiqmmfsrc plugin (downstream) or libcamerasrc (upstream). Tests run in a specific sequence to validate different camera capabilities progressively.

The test suite automatically detects which camera source plugin is available:

1. qtiqmmfsrc (Qualcomm CAMX downstream): Runs 10 tests

   • Fakesink (2) + Preview (2) + Encode (6)
   • Priority: Used by default when both plugins are detected
   • Supports NV12 and UBWC formats

2. libcamerasrc (upstream): Runs 7 tests

   • Fakesink (2) + Preview (2) + Encode (3)
   • Used when qtiqmmfsrc is not available or explicitly requested
   • Supports NV12 format only

This PR would be much easier to review and maintain if it is reduced to the minimum supported feature set.

Right now the suite is over-expanded for an initial submission: the runner is very large, the README is very long, and the shared library change includes helper additions that do not appear to be required by the suite’s current execution path.

Please tighten this PR. Suggested cleanup:

1. Remove interfaces that are not actually implemented end-to-end yet

   • e.g. --test-name / CAMERA_TEST_NAME if single-test filtering is not wired up
   • remove snapshot-related helper additions if snapshot tests are not actually executed

2. Keep only shared lib_gstreamer.sh helpers that are used by this suite today

3. Reduce the README to the essentials

   • overview
   • prerequisites
   • actual supported test matrix
   • parameters
   • basic troubleshooting

4. Split into 2 commits

   • shared helper additions
   • Camera_Tests suite files

5. Fix the YAML wrapper to the repo-standard form while respinning

If needed, it would also be reasonable to reduce this to a smaller MVP first (for example only the verified backend/test paths), and then add more coverage in follow-up PRs.

[nitinn22]

• Removed pipeline related functions from the lib_gstreamer.sh
• Fixed a timeout bug in GStreamer pipeline execution
• Enhanced error detection with SIGSEGV/crash detection, currently camera preview shows this error on recent builds.
• Improved test output with file size reporting for encode tests

[smuppand]

Please squash the commits into

At most, 2 logical commits would make sense:

1. shared Runner/utils/[lib_gstreamer.sh](http://lib_gstreamer.sh/) helper additions
2. Camera_Tests suite files

[nitinn22]

quashed commits as suggested.
Final history now contains two logical commits:

• shared Runner/utils/lib_gstreamer.sh helper changes
• Camera_Tests suite files and all follow‑up fixes

Please review. Thanks!

The PR is much closer now, and I no longer see the previous major structural blockers. Only minor comment fixes and the main shell lint issues remain.

To get the camera working, we need to load the cdt first. This support is not available on LAVA yet; the scripts have been locally tested and validated already.

we are loading CDT for rb3gen2

Could you indicate which lava job is running the camera tests?

sorry missed earlier to place the lava job and here is the lava job where we ran on next branch and waiting for these changes to consume in meta-qcom https://lava.infra.foundries.io/scheduler/job/181041#L205

I’ve rebased the branch onto the latest main, cleaned up the history, and force‑pushed with two focused commits. Please take another look.

resolved.

Tried on rb8, with has-camera tag enabled. I see same errors for both
camera base tests: https://lava.infra.foundries.io/scheduler/job/185098 and
camera imsdk tests: https://lava.infra.foundries.io/scheduler/job/185087.
It could be the camera setup issue itself. @bhargav0610 @smuppand

@bhargav0610, could you please confirm whether the camera sensors are connected to the RB8 devices? @nitinn22, could you try using RB3GEn2, where the camera will be installed beforehand?

[smuppand]

@nitinn22 please address the execute permission issues for the run.sh https://github.com/qualcomm-linux/qcom-linux-testkit/actions/runs/24783804921/job/72824221798?pr=405

[nitinn22]

Fixed exec permissions on run.sh

[smuppand]

@nitinn22 Functionally this looks good to merge.

Only minor non-blocking notes remain:

• YAML still uses the older wrapper style and leaves send-to-lava.sh unquoted
• PR description has a small stale detail for libcamerasrc test split
• has 4 commits, please squash them.

Resolved all items.
