I have set the GST_DEBUG=3, and capture the log, both server and client log are all in the attach file. I will check my machine evirenment about x264enc, also I will continue to debug with the new log. </blockquote><div> From the log, it feels like the udpsrc is emitting packets which are not h264. My bat-senses say that you might have more than one thing connected to port 40000 on your system. I don't remember if I've already asked you to do so, but could you get a tcpdump from the receiving side/machine (well, actually it should be the same as the sending one ;) ). You can collect it with: tcpdump -ilo -s0 -w/path/to/tcpdump.cap </div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;"> Thank you very much for your fervor. </blockquote><div> Mastership requires continuous exercise, and you're giving me a good chance, so it is me who must thank you ;).
