Hi Nanang, Thanks for your reply. The issue is due to this problem, i get a segmentation fault, becuase i do a pjmedia_port_get_frame() and then call pjmedia_port_put_frame(), as the frame is empty so put_frame seg faults. Actually i dont want to do get_frames, until i am sure that jitter buffer is not empty. With existing problem in the code, pjmedia_port_get_frame() returns 'PJ_SUCCESS' and ''PJMEDIA_FRAME_TYPE_AUDIO', so there is no way for me to know whether the call has failed or not, so that i dont call put_frame() in case the call has failed. Is there any other work around, i tried using pjmedia_jbuf_get_state() before calling get_frame(), but as Pjmedia_stream is defined in the stream.c only, its giving me problems. Please let me know in case you have any idea to overcome this issue?

It just seems that the samples_count check is useless there.
