1. __init__(self: python_vali._python_vali.PySurfaceConverter, src_format: python_vali._python_vali.PixelFormat, dst_format: python_vali._python_vali.PixelFormat, gpu_id: int) -> None

   Constructor method.

   param src_format:

   input Surface pixel format

   param dst_format:

   output Surface pixel format

   param gpu_id:

   what GPU to run conversion on

2. __init__(self: python_vali._python_vali.PySurfaceConverter, src_format: python_vali._python_vali.PixelFormat, dst_format: python_vali._python_vali.PixelFormat, stream: int) -> None

   Constructor method.

   param src_format:

Methods

Run(self, src, dst, cc_ctx)	Perform pixel format conversion.
__init__(*args, **kwargs)	Overloaded function.

Run(self: python_vali._python_vali.PySurfaceConverter, src: VPF::Surface, dst: VPF::Surface, cc_ctx: Optional[python_vali._python_vali.ColorspaceConversionContext] = None) → Tuple[bool, python_vali._python_vali.TaskExecInfo]

Perform pixel format conversion.

Parameters:

• src – input Surface. Must be of same format class instance was created with.

• dst – output Surface. Must be of suitable format.

• cc_ctx – colorspace conversion context. Describes color space and color range used for conversion. Optional parameter. If not given, VALI will automatically pick supported color conversion parameters.

Returns:

tuple containing: success (Bool) True in case of success, False otherwise. info (TaskExecInfo) task execution information.

Return type:

tuple
