◆ THPVideoDecode()

THPFileInfo * THPVideoDecode ( void * hdr,
void * status_out,

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

Parameters
headerFrame dimensions.
status_outReceives the status code: 0 on success, an error code otherwise.
workThe decode work area, sized by THPDec_8032FD40.
dataThe compressed frame data.
descThe image descriptor built by THPDec_8032F8D4.
Returns
work, ready for THPDec_80331340 / THPDec_803313D0, or NULL if the frame could not be read.
