Data Fields
uint32_t	width
	Image width in pixels.
uint32_t	height
	Image height in pixels.
uint32_t	pixel_format
	Pixel format enum (1=RGB24, 2=RGBA32, 3=BGR24, 4=BGRA32).
uint32_t	compressed_size
	Compressed data size (0 = not compressed, >0 = compressed).
uint32_t	checksum
	CRC32 checksum of pixel data.
uint32_t	timestamp
	Timestamp when frame was captured (milliseconds since epoch).

Detailed Description

Describes one compressed image sent through ACIP. width, height, and pixel_format tell the decoder how to interpret the payload; compressed_size bounds the following bytes, and checksum plus timestamp support validation and frame ordering. The packet header is fixed-size, but the image bytes are variable-length and owned by the packet buffer.

Image frame packet structure (Packet Type 3)

Contains raw RGB image with dimensions from camera/webcam. Used when client sends camera frames to server for ASCII conversion.

Note: Pixel data follows this header in the packet payload.; Format: rgb_pixel_t pixels[width * height] or compressed data; Pixel formats are defined in common.h
