Hi All,

I am facing issues when i call pjmedia_port_get_frame() and there are no frames in the jitter buffer.

I am using streams (so get_frame() from stream.c gets called), and i get the following error :- strm0x81052ac  Jitter buffer empty (prefetch=0), that seems to be OK.

But the issue is the "frame->type" returned is always "PJMEDIA_FRAME_TYPE_AUDIO", instead of "PJMEDIA_FRAME_TYPE_NONE".

I looked at the get_frame() code in stream.c file, and i think the code has a BUG in case the frame->type is "PJMEDIA_JB_ZERO_EMPTY_FRAME", as 'samples_count' will never be 0, on the basis of which we assign the value to 'frame->type' at the end of get_frame() callback.

Did anybody else also faced the similar problem or could somebody pl help?

Thanks n regards,
Manjeet
