/*
Psychtoolbox3/Source/Common/SCREENCloseMovie.c
AUTHORS:
mario.kleiner at tuebingen.mpg.de mk
PLATFORMS:
This file should build on any platform.
HISTORY:
10/23/05 mk Created.
DESCRIPTION:
Close a previously opened movie file and release all associated ressources.
On OS-X, all movie/multimedia handling functions are implemented via the Apple Quicktime API,
version 7 or later. On a later Windows port we'll probably do the same, but for other OS'es,
e.g., Linux, we would use a different multimedia engine.
TO DO:
*/
#include "Screen.h"
static char useString[] = "Screen('CloseMovie', moviePtr);";
static char synopsisString[] =
"Close movie object specified by 'moviePtr' and release all associated ressources.";
static char seeAlsoString[] = "CloseMovie PlayMovie GetMovieImage GetMovieTimeIndex SetMovieTimeIndex";
PsychError SCREENCloseMovie(void)
{
int moviehandle = -1;
// All sub functions should have these two lines
PsychPushHelp(useString, synopsisString, seeAlsoString);
if(PsychIsGiveHelp()) {PsychGiveHelp(); return(PsychError_none);};
PsychErrorExit(PsychCapNumInputArgs(1)); // Max. 1 input args.
PsychErrorExit(PsychRequireNumInputArgs(1)); // Min. 1 input args required.
PsychErrorExit(PsychCapNumOutputArgs(0)); // No output args.
// Get the window record from the window record argument and get info from the window record
//PsychAllocInWindowRecordArg(kPsychUseDefaultArgPosition, TRUE, &windowRecord);
// Only onscreen windows allowed:
//if(!PsychIsOnscreenWindow(windowRecord)) {
// PsychErrorExitMsg(PsychError_user, "OpenMovie called on something else than an onscreen window.");
//}
// Get the movie handle:
PsychCopyInIntegerArg(1, TRUE, &moviehandle);
if (moviehandle==-1) {
PsychErrorExitMsg(PsychError_user, "CloseMovie called without valid handle to a movie object.");
}
// Try to delete the movie object, releasing all associated ressources:
PsychDeleteMovie(moviehandle);
// Ready!
return(PsychError_none);
}
