Function Documentation

void close_movie_dat (  void    )

Close the datafile and free the memory. After close_movie() determines the type of the movie is a datafile, this function is called. It will call unload_datafile() to destroy the datafile, and free the memory allocated to XviD interface. Returns: Nothing See also: close_movie(), close_movie_avi(), dec_stop_xvid() Author: Eduardo "Dudaskank" Date: Created : 30/09/2002 Updated : 14/03/2003

int open_movie_dat (  AL_CONST char *    file )

Function to open a datafile. If the extension of file is .dat, this function is called. It will open the datafile, search for the subtype of the movie (jpg or m4v), search the sample and search for a object of type 'INFO', with information about dimensions of frame, fps, description, etc. Because version 1.0 don't have the width and the height of the frames, if these variables aren't presents, the function tries to determine the dimensions of the frame using load_memory_jpeg(). Returns: 1 on error, 0 ok See also: open_movie(), open_movie_avi() Author: Eduardo "Dudaskank" Date: Created : 30/09/2002 Updated : 08/03/2003

int play_movie_dat (  BITMAP *    bmp, int(*    callback)() )

Play a movie from a datafile. This function is like play_fli(). The movie has been previously opened with open_movie(), and this function is called if the movie is in a datafile. The bmp is the destination bitmap, and callback, if not NULL, will be called every time during the execution of the movie. If callback returns non zero, the movie stops. Returns: 1 on error, 0 ok See also: play_movie(), play_movie_avi() Author: Eduardo "Dudaskank" Date: Created : 01/10/2002 Updated : 04/04/2003

int update_movie_frame_dat (  void    )
