Yes but the same docker image works on centos7 host, and the binaries from the sdk seem to work. This ldd shows it finds the libndi.so.5 => /usr/local/lib/libndi.so.5
10 pub fn initialize() -> bool {
11 unsafe { NDIlib_initialize() }
12 }
13
38
39 fn plugin_init(plugin: &gst::Plugin) -> Result<(), glib::BoolError> {
40 if !ndi::initialize() {
41 return Err(glib::glib_bool_error!("Cannot initialize NDI"));
42 }
43
44 device_provider::register(plugin)?;
