<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>I’m currently working on a coding project for a
device similar to an IP-camera which streams via rtsp using an MPEG-4 codec.
I’m trying to set up a testing environment on my local PC for that I
don’t have the hardware available all the time. To do so, I’ve been
experimenting with the built in rtsp streaming server in VLC. Unfortunately it
turned out, that the VLC servers behaviour differs, I can connect to VLC using
the ffmpeg built in rtsp handler but when I try to connect to the IP-camera
using ffmpeg I get “error while parsing header” message.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>Therefore I’m currently evaluating other
methods of building a streaming client and since I can view the rtsp stream
with VLC (as a client) and VLC is said to use the Live555 library for rtsp
handling I thought it might be a good idea to take a closer look.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>My basic question is whether it is sufficient to test
if openRTSP can connect to my IP-camera to be able to say that Live555 supports
my device and I can go on working with it.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>Additionally what I’ve noticed during my
testing is that openRTSP seems not to be able to connect to a VLC streaming
server (it says “Failed to setup subsession: Missing or bad
"Transport:" header”), obviously openRTSP and VLC are not
compatible (using ffmpeg as client works fine) but how can this be since both
are based on the same library?<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>In a further step I will need the decoded frames as
arrays of rgb or grayscale values, is this possible with Live555? The website
says some video processing is supported.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span lang=EN-GB style='font-size:
10.0pt;font-family:Arial'>I’ve tested with live.2010.06.15 and VLC 1.0.5
and FFmpeg version SVN-r23512, to setup VLC as a testing server I took the
following steps from the main window: Extras->VLM configuration->Media
Manager Edition: VOD<o:p></o:p></span></font></p>
