</span>The official website is <a href="https://gstreamer.freedesktop.org/" rel="noreferrer" target="_blank">https://gstreamer.freedesktop.org/</a> where you<br>
can find the latest sources. The instructions on the website you found<br>
are for "Linux from scratch", a manually built Linux distribution.<br>
<br>
Installing like that on Raspbian can easily create conflicts with your<br>
system installation of GStreamer. There should also be newer binaries<br>
for the RPi available.<br>

<br>
</span>Try running ldconfig. This means most likely that your system still<br>
uses the old libgstreamer-1.0.so.0 instead of the newly installed one.<br>
<br>
It can also very well be that /usr/lib/arm* is higher up in the LD<br>
library path than /usr/lib, in which case ldconfig wouldn't fix it. <br>
<br>
Installing GStreamer into /usr/local would've worked for example<br>
though. You have to be careful when installing things on top of the<br>
directories meant for the distribution (i.e. /usr, but /usr/local is<br>
your's).<br>

<br>
</span>Install GStreamer packages for your distribution that provide a newer<br>
version, or install GStreamer and all the plugin modules in a place<br>
that has higher priority than /usr (e.g. /usr/local). You might run<br>
into incompatibilities with other applications from your distribution<br>
then though, and you need to ensure that you compile everything<br>
correctly for the RPi distribution.<br>
