ADHOC-56240: Enhance video_motion to support multiple videos

[batonai-coding-assistant]

Motivation for the Change

• To enable the processing of multiple video files concurrently, enhancing the application's efficiency and user experience.
• Address the limitation of the current system that only supports single video processing.

Summary of Changes

• Refactored the 'video_motion' method in the 'Sensync' class to accept a list of video paths instead of a single path.
• Implemented threading to process each video concurrently, improving performance in multi-video environments.
• Added comprehensive error handling to manage exceptions such as file not found, unsupported video formats, and general processing errors.

Differences from the Previous Implementation

• The previous implementation could only handle one video at a time, which was a bottleneck for users needing batch processing.
• The new implementation uses threading to leverage multicore processors effectively, allowing simultaneous video processing.

Limitations and Next Steps

• The current threading model may need adjustments based on the specific hardware capabilities of the deployment environment.
• Further optimization might be required to handle an extremely large number of concurrent video processes without degrading performance.
• PR reviewers should check thread safety issues and ensure that shared resources are handled correctly.
