2.How to get the time stamp for player (not system time, it need return the position time stamp)?

You need to accumulate the playing time as the stream is decoded. You can do this in your output callback with something like:

static mad_timer_t current_time;

mad_timer_add(&current_time, header->duration);

To translate the current playing time into specific units, use something like:

long milliseconds;

milliseconds = mad_timer_count(current_time, MAD_UNITS_MILLISECONDS);

Or you can use a sprintf-style conversion:

char time_str[18];

mad_timer_string(current_time, time_str, " %02lu:%02u:%02u", MAD_UNITS_HOURS, 0, 0);
