2. A confirmation message appears once the component is saved successfully.

3. The component is now ready to pass video data in the pipeline workflow.

Notes

• Stream Modes:

  • Live: Continuously processes incoming video streams.

  • Media File: Processes stored video files once.

• Partition Time is only required in Live mode.

• Ensure the SFTP target directory has sufficient permissions.

• Use Intelligent Scaling in real-time mode for dynamic workload optimization.
