<br><br>If I understand correctly you are having troubles to work in a gst-uninstalled

<br>> To use gstreamer-vaapi, I had to install libva and intel-driver for

<br>>
<br>> WARNING: erroneous pipeline: no element "vaapidecodebin"
</div></div>This is because you are in you system environment, using the system's
<br>gstreamer setup, not the one you compiled.

<br><br>This is odd, because you said you installed gstreamer 1.9.1 but you are using
<br>gst/master with gst-unistalled, which is master, not the tag 1.9.1
<br><br>I you follow the instructions in the page I referred before, you should have a
<br>symbolic link to gst-unstalled in gst/ named gst-master which you should
<br>execute to set up the uninstalled environment *for master branch*. You could
<br>also have a symbolic link to gst-1.9 aiming to release 1.9, for example.
<br><br>> 2. Again installing libva and intel-driver. Then recompiling
<br>> gstreamer-vaapi. This works again.
<br>>
<br>> Will I need to do it every time I boot the machine? Please help.
<br><br>Nope, you just have to setup your uninstalled environment correctly. And it is
<br>tricky if you use libva and intel-driver in a uninstalled fashion. It would be
<br>easier if you install the dev packages in you system. Otherwise, you have to
<br>modify your gst-unistalled script to add the proper variables aiming to your
<br>libva and intel-driver directories.
