<p class=MsoNormal><font size=2 face="Lucida Console"><span lang=EN-GB
style='font-size:10.0pt;font-family:"Lucida Console"'>First of all, thanks for having
answered to my last email.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face="Lucida Console"><span lang=EN-GB
style='font-size:10.0pt;font-family:"Lucida Console"'>I have another question
to make: can openRTSP record “.mp4” multiple Elementary Streams
files (i.e. with audio and video), or just “.m4e” Elementary Stream
files (with only audio or video, not both)?<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face="Lucida Console"><span lang=EN-GB
style='font-size:10.0pt;font-family:"Lucida Console"'>In fact, I still
don’t understand if, using openRTSP application, I can both record audio
and video signals, and save it as “.mp4”. <o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face="Lucida Console"><span lang=EN-GB
style='font-size:10.0pt;font-family:"Lucida Console"'>I read in documentation
that we can set the appropriate flags: “-v” to play only video
stream, “-a” to play only the audio stream, or “-y” to
synchronize audio and video tracks (at the moment, unfortunately, I have no camera
to record audio track, so I can’t do any tests, right now. I hope I will
soon).<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face="Lucida Console"><span lang=EN-GB
style='font-size:10.0pt;font-family:"Lucida Console"'>So, I’ve played the
OpenRTSP with these parameters: “-4 –e90 TLC-url >
FileName.mp4”<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face="Lucida Console"><span lang=EN-GB
style='font-size:10.0pt;font-family:"Lucida Console"'>to stream from an AXIS
Camera (without audio, only video) and I’ve recorded the stream into that
“.mp4” file (the flag -4 means that I build an mp4 container,
doesn’t it?). Then, using the test-program “live555MediaServer.exe”,
I’ve streamed it through my LAN and received it with a VLC RTSP Client.
And it works. <o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face="Lucida Console"><span lang=EN-GB
style='font-size:10.0pt;font-family:"Lucida Console"'>So, this is my doubt: as
you told me that Live555 streams only m4e files, I think that OpenRTSP save the
stream only in a *<b><span style='font-weight:bold'>m4e</span></b>* format. Is
it right? Or does it work only because I’ve used an *<b><span
style='font-weight:bold'>audioless</span></b>* camera?<o:p></o:p></span></font></p>
