Known Issues

Pipeline server exits with 2 GPU streams

Symptoms:

• When two GPU pipeline streams are started, the pipeline server exits from the container.

Hardware:

• Issue observed on BMG-580 discrete GPU.

WebRTC connectivity issues

Symptoms:

• Black video, no stream, or connection failures in the dashboard.

Checks:

• Verify HOST_IP in .env is reachable from the browser client.
• Confirm firewall rules allow the configured ports.

No models in dropdown

Symptoms:

• Model list is empty in the UI.

Checks:

• Ensure ov_models/ contains at least one model directory with OpenVINO IR files.
• If you downloaded models, re-run the stack so the service rescans.

Pipeline server unreachable

Symptoms:

• Starting a run fails; backend reports it cannot reach the pipeline server.

Checks:

• Ensure the dlstreamer-pipeline-server service is running.
• Verify PIPELINE_SERVER_URL (defaults to http://dlstreamer-pipeline-server:8080).

Port conflicts

If the dashboard or APIs are not reachable, check whether the ports are already in use and update the .env values (for example DASHBOARD_PORT).

Performance/throughput lower than expected

• Larger VLMs require more compute and memory; try a smaller model.
• Reduce max_tokens.
• Ensure hardware acceleration and drivers are installed if using GPU.

Gemma model not working in GPU

• Gemma model is not working on GPU. Only working on CPU.

Limited testing on EMT-S and EMT-D

• This release includes only limited testing on EMT‑S and EMT‑D, some behaviors may not yet be fully validated across all scenarios.
