inputyuv

Inputyuv is a software component or library used in multimedia processing, specifically designed to handle the input and decoding of video data in the YUV color space. YUV is a family of color spaces used in video systems where Y represents the luminance (brightness) component and U and V represent the chrominance (color) components. This separation allows for efficient compression and transmission of video signals.

The primary function of inputyuv is to read raw or encoded video streams that are formatted according to a YUV standard. This might involve reading from files, network streams, or directly from camera hardware. Once the data is read, inputyuv decodes it into a usable format for further processing by other multimedia applications or libraries. This decoding process translates the YUV pixel data into a representation that can be displayed or manipulated by software, such as RGB.

Inputyuv often supports various YUV formats and subsampling schemes, such as YUV 4:4:4, YUV 4:2:2, and YUV 4:2:0. These subsampling methods reduce the amount of chrominance information stored, taking advantage of the human eye's lower sensitivity to color detail compared to brightness. The specific implementation of inputyuv can vary, but its core purpose remains consistent: providing a reliable way to ingest and prepare YUV video data for use in applications like video editors, media players, and computer vision systems.
