<div class=WordSection1>
<p class=MsoNormal>I am attempting to write a mpeg-ts application. Step one
would be getting an existing application working, so I can dissect the code.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>So, I first took output-example (and the latest release),
and modified the av_guess_format to:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><span style='font-size:8.0pt;font-family:"Courier New"'>fmt
= av_guess_format("mpegts", NULL, NULL);<o:p></o:p></span></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I also modify the STREAM_DURATION to be very long (500000)
or so. I know this will be an issue, but I'm trying to get it working.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I compile and run it, wishing to write to the network, and
then read it locally using ffplay/vlc.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><span style='font-size:8.0pt;font-family:"Courier New"'>[root@sl6

<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I then try VLC, where I play network stream
"rtp://192.168.1.2:9778" (this is on the same machine as the
sender).<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>No output. Under messages, it says "rtp warning: too
many RTP sessions".<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>So, I check wireshark, and when VLC is not running, I am
getting icmp port not open messages, and those go away when I start VLC.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Any thoughts? Something not quite set up right in the TS options?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
