void v2u_convert_yv12_to_rgb24	(	void *	dst,
		const void *	src,
		int	row,
		int	w,
		int	h
	)

Pixel format converters. Convert a single row from one format to another. Parameters: dst - points to the destination buffer that receives the requested row in RGB24 or BGR24 format src - points the source image row - index of the row to transform w - width of the row in pixels h - height of the row in pixels

The source image is assumed to be tightly packed, i.e. no padding between the rows.

V2U_BOOL v2u_copy_line	(	void *	dst24,
		const void *	bmp,
		int	fmt,

Copies BMP row (or a part of it) that came from VGA2USB into 24-bit RGB row in the format understood by JPEG and PNG libraries. The following image formats are supported:

V2U_GRABFRAME_FORMAT_Y8 V2U_GRABFRAME_FORMAT_RGB4 V2U_GRABFRAME_FORMAT_RGB8 V2U_GRABFRAME_FORMAT_RGB16 V2U_GRABFRAME_FORMAT_BGR16 V2U_GRABFRAME_FORMAT_RGB24 V2U_GRABFRAME_FORMAT_BGR24 V2U_GRABFRAME_FORMAT_ARGB32

◆ v2u_edid_read()

V2U_BOOL v2u_edid_read	(	FILE *	in,
		V2U_UINT8	edid[V2U_EDID_SIZE]
