Description:      This function will play a section of audio CD from start_mmssff      to end_mmssff. When this section is finish, the end_of_play      variable will be set to 1.--------------------------------------------------------------------------  Function: av_play_motion_video  Parameters:      start_mmssff :           the start time in BCD's minute, second and frame format.      end_mmssff:          the end time in BCD's minute, second and frame format.  Description:      This function will play a section of motion video from start_mmssff      to end_mmssff. When this section is finish, the end_of_play      variable will be set to 1.-------------------------------------------------------------------------  Function: av_play_still  Parameters:      start_mmssff :           the start time in BCD's minute, second and frame format.      end_mmssff:          the end time in BCD's minute, second and frame format.      type : value should be "0xe1" or "0xe2".  Description:      This function will play a section of still video from start_mmssff      to end_mmssff. When this section is finish, the end_of_play      variable will be set to 1.--------------------------------------------------------------------------  Function:av_play_pause   Description:      This function will pause the playing section.--------------------------------------------------------------------------  Function: av_play_resume  Description:      This function will take the player from trick mode to normal      mode.      trick mode includes FF/FR, slow motion, step and pause.--------------------------------------------------------------------------  Function: av_play_slow_motion  Parameters:      field_length : The number of field time that a picture should be                     display. For a normal speed NTSC picture, the		     field_length is 2. If we want to make the slow		     motion to 1/2 speed of normal speed, we need to		     set field_length value to 4.  Description:      Plays slow motion.--------------------------------------------------------------------------  Function: av_play_mute  Parameters:      flag :	The audio will be mute if the flag value is not 0.  Description:--------------------------------------------------------------------------  Function:av_play_step  Description:      When this function is called, the player will display a new       decoded picture.--------------------------------------------------------------------------  Function: av_play_fast_forward/av_play_fast_rewind  Parameters:      mmssff:	The jump time after an I frame is displayed. The format                of mmssff is BCD's 0xmmssff format.      end_mmssff: When the end_mmssff is played, the vcx_fast_speed_done                  variable will be set to 1. The called should check		  this variable and decide what to do.  Description:      This function will cause the decoder to a fast forward/rewind  mode.--------------------------------------------------------------------------------------------------------------------------------------------------*/#endif
