now, another problem rises:
video packet size: 5978
video packet size: 5924
video packet size: 6849
video packet size: 5995
video packet size: 6067
video packet size: 6167
how should I put it into RTP packets of 1300 bytes? well, for example,
if the size is
6067 bytes, then it fits into 5 packets, the first 4 consits of 1300
bytes data, but the last's
payload is only 867 bytes. can I indicate it in the header?
Thanks in advance,
