THPVideoDecode()

THPFileInfo * THPVideoDecode	(	void *	hdr,
		void *	status_out,
		THPFileInfo *	work,
		void *	data,
		THPDec_8032FD40_Data *	desc )

Reads the headers of one compressed THP video frame into work.

Parameters

header	Frame dimensions.
status_out	Receives the status code: 0 on success, an error code otherwise.
work	The decode work area, sized by THPDec_8032FD40.
data	The compressed frame data.
desc	The image descriptor built by THPDec_8032F8D4.

Returns

work, ready for THPDec_80331340 / THPDec_803313D0, or NULL if the frame could not be read.
