Add Visual Progress Indicator During OCR Processing

[ES-scripts]

Describe the feature

Problem Description
Currently, VideOCR only shows log messages in the console/log area during the OCR extraction process.
There's no clear visual feedback about the progress of the operation, making it difficult for users to know:

• How much of the video has been processed
• How long the process will take
• If the application is actually working or frozen

This is especially problematic for long videos where the process can take several minutes or even hours.

Proposed Solution
Add a comprehensive progress indicator to the GUI that shows:

Essential Features:

• Progress Bar: Visual bar showing percentage completion (0-100%)
• Real time Percentage: Numeric percentage (e.g., "16.7% complete")
• Estimated Time: Time remaining estimate (e.g., "~5 minutes remaining")

Optional Enhancements:

• Processing speed indicator (frames per second)
• Current processing phase (Frame Extraction → OCR → Post-processing → Generating SRT)
• Elapsed time counter
• Option to pause/resume processing

Current Behavior
Users only see text logs appearing every 5%, which requires:

• Guessing if the process is running properly and interpreting log messages
• Mentally guessing how much time left
• Uncertainty about whether the app is frozen or working

Expected Behavior
Users should see at a glance:

• Clear visual progress bar
• Exact numeric progress information
• Estimated completion time
• Confirmation that processing is active

Technical Suggestions
Since VideOCR using Tkinter for the GUI, this could be implemented with:

• ttk.Progressbar widget for the visual bar
• Label widgets for text information
• Progress updates during the frame processing loop
• ETA calculation based on processing speed

Benefits

• Better UX: Users know exactly what's happening
• Reduced anxiety: Clear feedback that the app is working
• Time management: Users can estimate if they have time to wait or should come back later
• Professional appearance: Matches expectations from modern applications

Environment

• VideOCR version: [1.32 CUDA12.9]
• OS: Windows [WIN11]
• Installation method: [Installer.exe]

Additional Context
This is a common feature in similar OCR/video processing tools and would significantly improve the user experience, especially for first-time users who might think the application has frozen during long processing tasks.

Amazing work Thanks

with the way paddleocr works
I don't know if a indicator would be very accurate
