Added URL pre-filtering to avoid unnecessary yt-dlp checks Added common video platform patterns for quick filtering Reduced error logging noise from non-URL words Improved URL validation efficiency FFmpeg Management: Enhanced FFmpeg binary verification Added robust error handling for subprocess calls Improved cleanup of failed operations Added detailed logging for binary operations Error Handling: Fixed exception hierarchy in utils/exceptions.py Added proper error types for different failure scenarios Enhanced error messages with more context Improved error propagation through the system Process Flow: Added proper timeout handling for subprocess calls Enhanced environment variable handling Better cleanup after failures Added retry mechanisms for failed operations
