Overview

Extend the image HTTP E2E scenario from #17414 with a video request through Dynamo's public API, Rust frontend, TRT-LLM sidecar, and OpenEngine. The response must identify the triangle in the checked-in MP4.

Draft, stacked on #17414. Also depends on video wiring #16870 and a shared Dynamo TRT-LLM runtime container containing the merged upstream video support from NVIDIA/TensorRT-LLM#20654. Refresh this branch with the video wiring before GPU validation. No personal-fork engine pin or runtime source overlay is added.

Details

• Reuse the image scenario's single Qwen3-VL-2B engine for both requests; rename the scenario to trtllm_aggregated_multimodal.
• Start the local media fixture server for this scenario and enable local URL access only in its test environment.
• Install the validated OpenCV decoder package for the test and retain post-merge scheduling, the one-GPU marker, and the existing KV budget.
• Reuse test(trtllm): add post-merge image sidecar E2E coverage #17414's policy that required TRT-LLM CI fails if OpenEngine is missing rather than silently skipping.

The official-upstream nightly video test belongs to #16870. This follow-up covers the full HTTP path using Dynamo's shared runtime container.

Validation

• Seven existing runtime-policy/probe CPU cases passed in an isolated copy, without loading an inference backend.
• Targeted pre-commit checks and whitespace checks passed.
• GPU HTTP serving and the combined scenario's memory profile remain unvalidated. The local host reports an NVIDIA driver/library mismatch; the shared runtime upgrade and prerequisites must be validated before merge.

Where should the reviewer start?

trtllm_aggregated_multimodal and its media-server setup in tests/serve/test_sidecar.py. This PR changes only that file relative to #17414.

Related Issues

• Depends on test(trtllm): add post-merge image sidecar E2E coverage #17414 and feat(trtllm): support videos through the OpenEngine sidecar #16870.
• Relates to DIS-2971; this is video HTTP coverage and does not close its full scope.
