/*
Psychtoolbox3/Source/Common/SCREENGetMovieTimeIndex.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[] = "timeindex = Screen('GetMovieTimeIndex', moviePtr);";
static char synopsisString[] = "Return current time index for movie object 'moviePtr'.";
static char seeAlsoString[] = "CloseMovie PlayMovie GetMovieImage GetMovieTimeIndex SetMovieTimeIndex";
PsychError SCREENGetMovieTimeIndex(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(1)); // One output arg.
// Get the movie handle:
PsychCopyInIntegerArg(1, TRUE, &moviehandle);
if (moviehandle==-1) {
PsychErrorExitMsg(PsychError_user, "GetMovieTimeIndex called without valid handle to a movie object.");
}
// Retrieve and return current movie time index:
PsychCopyOutDoubleArg(1, TRUE, PsychGetMovieTimeIndex(moviehandle));
// Ready!
return(PsychError_none);
}
