Hi, I have query regarding the frame type returned by pjmedia_jbuf_get_frame2(). For a particular application I am developing, I want to know precisely whether an incoming media (audio) frame is lost or delayed (such that it has to be dropped) and I want this information just about when frames are being played out (i.e. after jitter buffer processing). For this I was using frame type returned from jitter buffer as an indicator i.e.if frame type is PJMEDIA_JB_MISSING_FRAME, frame is considered lost or dropped. However, I noticed from logs that when frames are lost (I physically "broke" the network connection), frame type shows up as PJMEDIA_JB_ZERO_EMPTY_FRAME and not PJMEDIA_JB_MISSING_FRAME. Could some one throw some more light on this? or have a different way to do this? Thanks, Anshuman
