Function Documentation

void direct_output	(	ImageParameters *	p_Img,
		InputParameters *	p_Inp,
		StorablePicture *	p,
		FrameFormat *	output,
		int	p_out
	)

Directly output a picture without storing it in the DPB. Fields are buffered before they are written to the file.

Parameters:

	p_Img	ImageParameters structure
	p_Inp	Input configuration parameters
	p	Picture for output
	output	Frame format for output
	p_out	Output file

Definition at line 489 of file output.c.

Here is the call graph for this function:

void direct_output_paff	(	ImageParameters *	p_Img,
		InputParameters *	p_Inp,
		StorablePicture *	p,
		FrameFormat *	output,
		int	p_out
	)

For adaptive frame/field coding remove dangling top field from direct output frame version instead.

Parameters:

	p_Img	Picture for output
	p_Inp	Input configuration parameters
	p	Picture for output
	output	Frame format for output
	p_out	Output file

Write out unpaired fields from output buffer.

Parameters:

	p_Img	ImageParameters structure
	p_Inp	Input configuration parameters
	output	FrameFormat structure for output
	p_out	Output file
