Conditions：live555 both in -Debug mode。
Result：live555MediaServer1 which data come from camera send out by rtsp, the vlc only see screem time run ,but no picture in screem.
live555MediaServer2 which data come from file send out by rtsp,the vlc is ok,can see picture.(this file is come from the live555MediaServer1 program,date come from the camera.)
as i know ,when live555MediaServer2 read from file , first read 15000 bytes, and then parse the Nalu,last sent RTP.
why?
and i ask some friends,they told me that maybe RTP time stamp is not correct here.
I paste a part of output data below.could you help me ,or give me some advices.
