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
