## I get an error that says something like (process:26626):

If you run GStreamer from git uninstalled, it means that
something changed in the core that requires a recompilation in the
plugins. Recompile the plugins by doing "make clean && make".
If you run GStreamer installed, it probably means that you run the
plugins against a different (incompatible) version than they were
compiled against, which ususally means that you run multiple
installations of GStreamer. Remove the old ones and - if needed -
recompile again to ensure that it is using the right version.
Note that we strongly recommend using Debian or RPM packages, since you
will not get such issues if you use provided packages.
## The GStreamer application I used stops with a segmentation fault. What can I do ?
The first point of contact for any problems with a GStreamer application
should be the developers of that application. They will be able to investigate
whether the problem lies with the application or with GStreamer, and will pass
on any issues to GStreamer developers if needed.
There are two things you can do. If you compiled GStreamer with
specific optimization compilation flags, you should try recompiling
GStreamer, the application and the plug-ins without any optimization

## On my system there is no gst-register command.
Since GStreamer version 0.10 this is not needed anymore. The
registry will be rebuilt automatically. If you suspect the registry is
broken, just delete the `registry.*.xml` files under
`$HOME/.gstreamer-1.X/` and run
```
gst-inspect-1.0
```
to rebuild the registry.
