The problem is that special headers called SPS and PPS (sequence
parameter set and picture parameter set) are not included in the file.
Those headers may be carried in-band (which is probably not your case)
or in the SDP.
My guess is that your source sent them in the SDP and not in-band (in

few things you must notice:
1.doGetNextFrame should NOT call deliver frame. it should only scheduled
deliverFrame in the taskSchedulaer waiting on some socket or the
watchVariable.
2. you call startPlaying only once!!! (when you want to start playing -
it should not be used to notify new data.
