The video downloading issues have been resolved by implementing comprehensive error handling and resource management:

FFmpeg is now properly managed:

Binaries are downloaded and verified on startup
Permissions are properly set
Hardware acceleration is detected and used when available
Resources are cleaned up properly
Error handling has been improved:

Specific exception types for different errors
Better error messages and logging
Appropriate reaction indicators
Enhanced component error handling
Resource management has been enhanced:

Failed downloads are tracked and cleaned up
Temporary files are handled properly
Queue management is more robust
Concurrent downloads are better managed
Verification has been strengthened:

FFmpeg binaries are verified
Video files are validated
Compression results are checked
Component initialization is verified
