python_vali.PyNvJpegEncoder

class python_vali.PyNvJpegEncoder

__init__(self: python_vali._python_vali.PyNvJpegEncoder, gpu_id: int) → None

Constructor method.

Parameters:

gpu_id – what GPU to run encode on

Methods

Context(self, compression, pixel_format)	NvJpegEncodeContext structure contains state and parameters of PyNvJpegEncoder, including given compression coefficient (100 = maximum quality) and PixelFormat.
Run(self, context, surfaces)	Encode multiple Surfaces.
__init__(self, gpu_id)	Constructor method.

Context(self: python_vali._python_vali.PyNvJpegEncoder, compression: int, pixel_format: python_vali._python_vali.PixelFormat) → python_vali._python_vali.NvJpegEncodeContext

NvJpegEncodeContext structure contains state and parameters of PyNvJpegEncoder, including given compression coefficient (100 = maximum quality) and PixelFormat. Using one context in multiple threads is prohibited.

Returns:

new NvJpegEncodeContext.

Run(self: python_vali._python_vali.PyNvJpegEncoder, context: python_vali._python_vali.NvJpegEncodeContext, surfaces: List[python_vali._python_vali.Surface]) → Tuple[List[numpy.ndarray], python_vali._python_vali.TaskExecInfo]

Encode multiple Surfaces. In case of an error it returns empty list and TaskExecInfo.FAIL.

Parameters:

• context – context (NvJpegEncodeContext)

• surfaces – list of input Surfaces

Returns:

tuple, the first element is the list of buffers compressed images. The second element is TaskExecInfo.
