Problems instaling gstreamer-vaapi in Gstreamer 1.18

[peter12]

I manage to have installed and compiled the plugin VA-API in GStreamer 1.14.

However, I usually use  Gstreamer 1.18, so I would like to compile the plugin to use it in that version.
https://github.com/GStreamer/gst-build

Therefore, I download and unzip gstreamer-vaapi-1.18.0 from this source (http://www.linuxfromscratch.org/blfs/view/svn/multimedia/gstreamer10-vaapi.html), and following the instructions I build it.

```
mkdir build &&
cd    build &&

meson  --prefix=/usr       \
       -Dbuildtype=release \
       -Dpackage-origin=http://www.linuxfromscratch.org/blfs/view/svn/ &&
ninja

ninja install
```
However, when I try to inspect if the elements are installed or not, I obtain the next output as a result:

$ gst-inspect-1.0 vaapi

No such element or plugin 'vaapi'

I have to say that i am new with GStreamer and in the ubuntu environment. What can I do?

Did the `ninja install` command succeed? If you're running as a non-root user, you probably need to run `sudo ninja install`, since it will attempt to place files in a system directory that normal users don't have write access to.

Hi,

Firstly, I have the next error when executing the command "ninja":

gstreamer-vaapi 1.18.0

  Subprojects
    gst-plugins-base: NO Subproject directory not found and
gst-plugins-base.wrap file not found
              libdrm: NO Subproject directory not found and libdrm.wrap file not found

I have compiled the gst-build in another directory, and inside it is the subprojects directory. So how could I tell to the terminal to find in that path?
