<div bgcolor="#FFFFFF" text="#000000"> gdpdepay is part of
plugins-bad. plugins-bad have also opencv plugins. so that
is why there is dependency on opencv packages. also this
is more Ubuntu packages and how they are created that
gstreamer problem.<br>
<br>
if you don't want install opencv from repository you must
compile it for yourself.<br>

<div>This is unacceptable to me.</div>
<div>1) How come gstreamer relies on OpenCV?</div>
<div>2) I've already upgraded OpenCV to 2.4.9, I
really don't want to use the default OpenCV from

Hi, all:
<div><br>
</div>
<div>1) My environment:</div>
<div>Ubuntu 14.04</div>
<div><br>
</div>
<div>2) Symptom:</div>
<div>I just want to enable gstreamer
on my Ubuntu, however, it seems
there are so many versions on the
same operating system.</div>
<div><br>
</div>
<div>
<div>/usr/lib/x86_64-linux-gnu$
ls -ld gstreamer*</div>
<div>drwxr-xr-x 2 root root 12288
May 26 01:03 gstreamer-0.10</div>
<div>drwxr-xr-x 3 root root 4096
Apr 2 15:33 gstreamer0.10</div>
<div>drwxr-xr-x 2 root root 4096
May 26 00:43 gstreamer-1.0</div>
<div>drwxr-xr-x 3 root root 4096
Apr 2 15:33 gstreamer1.0</div>
<div><br>
</div>
<div><br>
</div>
<div>Why not just enable a single
version in Ubuntu 14.04? My
current situation is:</div>
<div>when I tried to launch
gstreamer as:</div>
<div>
<div>.../gstreamer$
gst-launch-1.0 -v
tcpclientsrc host=192.168.1.40
port=5000 ! gdpdepay !
rtph264depay ! avdec_h264 !
videoconvert ! autovideosink
sync=false</div>
</div>
<div><br>
</div>
<div>I got:</div>
<div><b>WARNING: erroneous
pipeline: no element
"gdpdepay"</b></div>
<div><br>
</div>
<div><br>
</div>
<div><br>
</div>
<div>Any suggestions please?</div>
<div><br>
</div>
<div><br>

<div>Cheers</div>
