[BUG]: No Captions Found Using GUI and Command-Line on Windows

[Ni1esh-Yadav]

Description:
I encountered an issue while trying to extract captions using both the CCExtractor GUI and command-line interface on Windows. Despite providing an input file that should contain captions, the software displays a message stating "No captions are found in the input file."

Steps to Reproduce:
Issue in GUI:
Open the CCExtractor GUI on a Windows machine.
Select an input file that is known to contain captions.
Start the extraction process using the default or custom settings.
Observe the output message: "No captions are found in the input file."

Issue in commandline:
1.make new folder and include ccextractorwinfull.exe into that folder than add the video in that folder of whom you want to extract the closecaptions
2. than make a file test.py containing
import subprocess
subprocess.run(['CCExtractor_win_portable\ccextractorwinfull.exe',
'video.mp4','-o','oututfile1.srt'])
make sure of indentation
3.now run this test.py file

Expected Behavior:
The software should extract captions from the input file, as it contains valid captions.

Actual Behavior:
The extraction process completes without any captions being found, even though the input file has valid captions.

Additional Details:

Operating System: Windows11
CCExtractor Version: 0.98
Input File Details: Include the type of file (.mp4)
