Enhance Error Handling for Missing Frames

[anushka226]

In the main_inference.py script, there is no error handling for cases where frames might be missing in the video directory. This can lead to the script crashing if a frame is missing, which is not ideal for robustness.

The script prints a warning and skips the missing frame, but it does not handle the case where multiple frames might be missing consecutively, which could lead to unexpected behavior.

Add a more robust error handling mechanism to handle missing frames gracefully. Specifically, we can introduce a counter to track consecutive missing frames and stop processing if a certain threshold is exceeded.
