int hdmv_vm_resume ( HDMV_VM *  p  ) 

Resume HDMV execution.

Continue execution of movie object after playlist playback. Do not restore backup PSRs. This function is called when playlist playback ends.

Parameters:
p HDMV_VM object
Returns:
0 on success, -1 if error

Referenced by bd_read_ext().

int hdmv_vm_suspend_pl ( HDMV_VM *  p  ) 

Suspend playlist playback.

This function assumes playlist is currently playing and movie object execution is suspended at PLAY_PL instruction.

If resume_intention_flag of current movie object is 1: Copy playback position PSRs to backup registers (suspend playlist playback at current position) If resume_intention_flag of current movie object is 0: Discard current movie object

Parameters:
p HDMV_VM object
Returns:
0 on success, -1 if error
