#include <ra8_camera_codec_jpeg_sw.h>

Data Fields
uint8_t *	rgb_workspace
	Caller-owned packed RGB workspace.
uint32_t	rgb_workspace_capacity
	Writable workspace bytes.
uint16_t	output_width
	Encoded image width.
uint16_t	output_height
	Encoded image height.
uint8_t	quality
	JPEG quality passed to the encoder.

Detailed Description

Configuration and caller-owned RGB workspace for software JPEG.

rgb_workspace_capacity must cover output_width * output_height * 3 bytes. For VGA UYVY to QVGA, configure 320x240 and provide 230400 bytes.

Invariant

Output dimensions are non-zero and their RGB byte count fits uint32_t.

quality is in the inclusive range 1..100.

0.1.0
