GlobalArgs ¶

Bases: ABC

Abstract base class for providing global FFmpeg command-line arguments.

This class defines an interface for setting global options that apply to the entire FFmpeg command. These options control the general behavior of FFmpeg such as logging levels, overwrite behavior, thread usage, and hardware acceleration.

Implementers must define the _global_node abstract method to apply these arguments to actual FFmpeg command execution.

`global_args`	Set global options.
