Re: [Linphone-developers] Bursty rtp traffic

[Simon Morlat]

Hi Vadim,

In order to synchronize the MSTicker to an external time, you can use:
/**
 * Override MSTicker's time function.
 * This can be used to control the ticker from an external time provider, for 
example the 
 * clock of a sound card.
 *
 * @param ticker  A #MSTicker object.
 * @param func    A replacement method for calculating "current time"
 * @param user_data Any pointer to user private data.
 */
void ms_ticker_set_time_func(MSTicker *ticker, MSTickerTimeFunc func, void 
*user_data);

And it's no more "hackish" !
