• error - Error types and error handling
• dictionary - Key-value metadata and options
• rational - Rational number representation for timestamps/framerates
• channel_layout - Audio channel layouts (stereo, 5.1, etc.)
• color - Color space and color primaries
• format - Pixel and sample formats
• mathematics - Mathematical utilities (rescaling, rounding)
• [time] - Time representation and conversion
• log - Logging configuration and levels
