Re: No plugins found in GStreamer static build at runtime

Hi Stephene,
Thanks a lot for your response,
I have solved the problem. However, Even though I have followed the
instructions in the manual, it seems that the application is still linked
against the shared library ("libgstreamer-full-1.0.so"). While I want to
link it with "libgstreamer-full-1.0.a" static library.
From the output of the `ldd` it is clear that the shared lib is still used:

> $ ldd ./example
> linux-vdso.so.1 (0x00007ffe05d0a000)
> libglib-2.0.so.0 => /lib/x86_64-linux-gnu/libglib-2.0.so.0
> (0x00007fd716002000)
> libgstreamer-full-1.0.so =>

> libgstreamer-full-1.0.so (0x00007fd712df8000)
> libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fd712bd0000)

I have attached the meson.build configuration for your reference.
