Fixes `plugin_define!` by using `libc::c_char` on aarch64
Before the plugin defined c_char
by itself as i8
, but on aarch64
c_char
is defined as u8
. The definition of c_char
in the macro
is removed and c_char
from libc
is used directly. To not require
the user to include libc
, it is exported by gst-plugin
.
